Oral and Oropharyngeal Cancer - Introduction

Approved by the Cancer.Net Editorial Board, 10/2022

ON THIS PAGE: You will find some basic information about these diseases and the parts of the body they may affect. This is the first page of Cancer.Net’s Guide to Oral and Oropharyngeal Cancer. Use the menu to see other pages. Think of that menu as a roadmap for this entire guide.

Cancer begins when healthy cells change and grow out of control, forming a mass called a tumor. A tumor can be cancerous or benign. A cancerous tumor is malignant, meaning it can grow and spread to other parts of the body. A benign tumor means the tumor can grow but will not spread.

Cancer of the oral cavity and cancer of the oropharynx are 2 of the most common types of cancer that develop in the head and neck region, a grouping called head and neck cancer. The oral cavity and oropharynx, along with other parts of the head and neck, give us the ability to chew, swallow, breathe, and talk.

The oral cavity includes the:

  • Lips

  • Lining of the lips and cheeks, called the buccal mucosa

  • Upper and lower gums, called the gingiva

  • Front two-thirds of the tongue

  • Floor of the mouth under the tongue

  • Roof of the mouth, also called the hard palate

  • Retromolar trigone, which is the small area behind the wisdom teeth

The oropharynx begins where the oral cavity stops. It includes the:

  • Soft palate at the back of the mouth

  • Part of the throat behind the mouth

  • Tonsils

  • Base of the tongue

More than 90% of oral and oropharyngeal cancers are squamous cell carcinoma. This means that they begin in the flat, squamous cells found in the lining of the mouth and throat. The most common locations for cancer in the oral cavity are:

  • Tongue

  • Tonsils

  • Oropharynx

  • Gums

  • Floor of the mouth

Although oral cancer and oropharyngeal cancer are commonly described using 1 phrase, it is important to identify exactly where the cancer began. This is because there can be differences in treatment between the 2 locations.

Oral and Oropharyngeal Cancer - Statistics

Approved by the Cancer.Net Editorial Board, 02/2023

ON THIS PAGE: You will find information about the estimated number of people who will be diagnosed with oral or oropharyngeal cancers each year. You will also read general information on surviving these diseases. Remember, survival rates depend on several factors, and no 2 people with cancer are the same. Use the menu to see other pages.

Every person is different, with different factors influencing their risk of being diagnosed with these cancers and the chance of recovery after a diagnosis. It is important to talk with your doctor about any questions you have around the general statistics provided below and what they may mean for you individually. The original sources for these statistics are provided at the bottom of this page.

How many people are diagnosed with oral and oropharyngeal cancer?

In 2023, an estimated 54,540 adults (39,290 men and 15,250 women) in the United States will be diagnosed with an oral or oropharyngeal cancer. Worldwide, an estimated 476,125 people were diagnosed with an oral or oropharyngeal cancer in 2020.

Rates of these 2 cancers are more than twice as high in men as in women. White people are slightly more likely to be diagnosed with them than Black people. Together, oral and oropharyngeal cancers are the eighth most common cancer among men. The average age of diagnosis is 64. These types of cancer can be diagnosed at any age, with about 20% of cases occur in people younger than 55.

From 2015 to 2019, oral and oropharyngeal cancers increased slightly (under 1%) per year (see Risk Factors and Prevention) in women and stayed steady in men. However, during the same years, oropharynx cancers related to human papillomavirus (HPV) infection rose by 1.3% in women and 2.8% in men. An estimated 50% of all oral cancers were diagnosed in the tongue or tonsils during 2015 to 2019, compared to 25% in the late 1970s.

It is estimated that 11,580 deaths (8,140 men and 3,440 women) from oral and oropharyngeal cancer will occur in the United States in 2023. After dropping for several decades, the death rate for these 2 diseases increased by slightly under half a percent each year from 2009 to 2020. This change was mainly due to a 2% increase in deaths during those years from oropharyngeal cancer related to HPV. In 2020, an estimated 225,900 people worldwide died from oropharyngeal cancer.

What is the survival rate for oral and oropharyngeal cancer?

There are different types of statistics that can help doctors evaluate a person’s chance of recovery from oral or oropharyngeal cancer. These are called survival statistics. A specific type of survival statistic is called the relative survival rate. It is often used to predict how having cancer may affect life expectancy. Relative survival rate looks at how likely people with oral or oropharyngeal cancer are to survive for a certain amount of time after their initial diagnosis or start of treatment compared to the expected survival of similar people without these cancers.

Example: Here is an example to help explain what a relative survival rate means. Please note this is only an example and not specific to this type of cancer. Let’s assume that the 5-year relative survival rate for a specific type of cancer is 90%. “Percent” means how many out of 100. Imagine there are 1,000 people without cancer, and based on their age and other characteristics, you expect 900 of the 1,000 to be alive in 5 years. Also imagine there are another 1,000 people similar in age and other characteristics as the first 1,000, but they all have the specific type of cancer that has a 5-year survival rate of 90%. This means it is expected that 810 of the people with the specific cancer (90% of 900) will be alive in 5 years.

It is important to remember that statistics on the survival rates for people with oral or oropharyngeal cancer are only an estimate. They cannot tell an individual person if cancer will or will not shorten their life. Instead, these statistics describe trends in groups of people previously diagnosed with the same disease, including specific stages of the disease.

The survival rates for oral and oropharyngeal cancer vary based on several factors. These include the stage and grade of cancer, a person’s age and general health, and how well the treatment plan works. Another factor that can affect outcomes is the original location.

The 5-year relative survival rate for oral or oropharyngeal cancer in the United States is 68%. The 5-year relative survival rate for Black people is 52%. For White people, it is 70%. Research shows that survival rates are higher in people who have HPV-associated cancer, which is more frequently diagnosed in White people (see Risk Factors and Prevention). However, a survival disparity still exists.

If the cancer is diagnosed at an early stage, the 5-year relative survival rate for all people is 86%. About 28% of oral and oropharyngeal cancers are diagnosed at this stage. If the cancer has spread to surrounding tissues or organs and/or the regional lymph nodes, the 5-year relative survival rate is 69%. An estimated half of cases are diagnosed at this stage. If the cancer has spread to a distant part of the body, the 5-year relative survival rate is 40%. About 17% of oral and oropharyngeal cancers are diagnosed at this stage.

Experts measure relative survival rate statistics for oral and oropharyngeal cancer every 5 years. This means the estimate may not reflect the results of advancements in how oral and oropharyngeal cancer is diagnosed or treated from the last 5 years. Talk with your doctor if you have any questions about this information. Learn more about understanding statistics.

Oral and Oropharyngeal Cancer - Risk Factors and Prevention

Approved by the Cancer.Net Editorial Board, 10/2022

ON THIS PAGE: You will find out more about the factors that increase the chance of developing oral and oropharyngeal cancers. Use the menu to see other pages.

A risk factor is anything that increases a person’s chance of developing cancer. Although risk factors often influence the development of cancer, most do not directly cause cancer. Some people with several risk factors never develop cancer, while others with no known risk factors do. Knowing your risk factors and talking about them with your doctor may help you make more informed lifestyle and health care choices.

The risk of oral and oropharyngeal cancers is greatly increased by 2 factors:

  • Tobacco use. Using tobacco, including cigarettes, cigars, pipes, chewing tobacco, and snuff, is the single largest risk factor for head and neck cancer. Eighty-five percent (85%) of head and neck cancer is linked to tobacco use. Pipe smoking in particular has been linked to cancer in the part of the lips that touch the pipe stem. Chewing tobacco or snuff is associated with a 50% increase in the risk of developing cancer in the cheeks, gums, and inner surface of the lips, where the tobacco has the most contact. Secondhand smoke may also increase a person’s risk of head and neck cancer.

  • Alcohol. Frequent and heavy consumption of alcohol increases the risk of head and neck cancer. Using alcohol and tobacco together increases this risk even more.

Other factors that can raise a person’s risk of developing oral or oropharyngeal cancer include:

  • Prolonged sun exposure. High exposure to the sun, without sun protection measures, is linked with cancer in the lip area.

  • Human papillomavirus (HPV). Research shows that infection with the HPV virus is a risk factor for oropharyngeal cancer. In recent years, HPV-related oropharyngeal cancer in the tonsils and the base of the tongue has become more common. Sexual activity, including oral sex, with someone who has HPV is the most common way someone gets HPV. There are different types of HPV, called strains. Research links some HPV strains more strongly with certain types of cancers.

    It is likely that receiving an HPV vaccination before exposure to HPV can reduce the risk of oropharynx cancer (see below).

  • Gender. Men are more likely to develop oral and oropharyngeal cancers than women.

  • Fair skin. Fair skin is linked to a higher risk of lip cancer.

  • Age. People older than 45 have an increased risk for oral cancer, although this type of cancer can develop in people of any age.

  • Poor oral hygiene. Lack of dental care and not following regular oral hygiene practices may cause an increased risk of oral cavity cancer. Poor dental health or ongoing irritation from poorly fitting dentures, especially in people who use alcohol and tobacco products, may contribute to an increased risk of oral and oropharyngeal cancers. Regular examinations by a dentist or dental hygienist can help detect oral cavity cancer and some oropharyngeal cancers at an early stage.

  • Poor diet/nutrition. A diet low in fruits and vegetables and a vitamin A deficiency may increase the risk of oral and oropharyngeal cancer. Chewing betel nuts, a nut containing a mild stimulant that is popular in Asia, also raises a person’s risk of developing oral and oropharyngeal cancers.

  • Weakened immune system. People with a weakened immune system may have a higher risk of developing oral or oropharyngeal cancer.

  • Marijuana use. Recent studies have suggested that people who have used marijuana may be at higher-than-average risk for head and neck cancer.

Prevention

Different factors cause different types of cancer. Researchers continue to look into what factors cause oral and oropharyngeal cancers, including ways to prevent it. Although there is no proven way to completely prevent this disease, you may be able to lower your risk. Several of the risk factors for oral and oropharyngeal cancers can be avoided by making healthy lifestyle choices.

Stopping the use of all tobacco products is the most important thing a person can do to reduce the risk of oral and oropharyngeal cancers, even for people who have been using tobacco for many years.

Another way to reduce your risk of developing oropharynx cancer is to reduce your risk of contracting HPV. It is likely that receiving an HPV vaccination before exposure to HPV can reduce the risk of oropharynx cancer. The Gardasil 9 vaccine helps prevent infection from HPV-16, HPV-18, and 5 other types of HPV linked to cancer.

In the United States, the vaccine is approved for anyone between the ages of 9 and 45. The U.S. Centers for Disease Control (CDC) recommends HPV vaccination for everyone through the age of 26 if not already vaccinated. Some adults between the ages of 27 and 45 who have not already been vaccinated may decide to get it after reviewing their risks for infection and the benefits of the vaccine with their doctor. Even if you already have 1 type of HPV, the vaccine may protect you from types of HPV you do not have.

Another way to reduce your risk of HPV infection is to limit your number of sexual partners. Having many partners increases the risk of HPV infection. Using a condom does not fully protect you from HPV during sex.

Also, to reduce your risk of lip cancer, reduce your exposure to sunlight and other sources of ultraviolet (UV) radiation. Read more about protecting your skin from the sun.

Talk with your health care team if you have concerns about your personal risk of developing these types of cancer.

ON THIS PAGE: You will find out more about screening for oral and oropharyngeal cancers. You will also learn the risks and benefits of screening. Use the menu to see other pages.

Screening is used to look for cancer before you have any symptoms or signs. Scientists have developed, and continue to develop, tests that can be used to screen a person for specific types of cancer. The overall goals of cancer screening are to:

  • Lower the number of people who die from the disease, or eliminate deaths from cancer altogether

  • Lower the number of people who develop the disease

Learn more about the basics of cancer screening.

Screening information for oral and oropharyngeal cancers

Many of the symptoms of oral or oropharyngeal cancer can be caused by other, noncancerous health conditions. Therefore, it is important for people to receive regular health and dental care, especially those who routinely drink alcohol, currently use tobacco products, or have used tobacco products in the past.

Many dentists now perform oral and oropharyngeal cancer screening checks at regular dental appointments for everyone. If you currently use alcohol and tobacco or have used them in the past, you should receive a routine evaluation from their dentist and primary care doctor on a regular basis. This is a simple, quick procedure in which the doctor looks in the nose, mouth, and throat for abnormalities and feels for lumps in the neck. If anything unusual is found, the doctor will recommend a more extensive examination using 1 or more of the diagnostic procedures mentioned in the Diagnosis section.

Cancers of the oral cavity and oropharynx have a much better chance of being cured when they are caught early.

The next section in this guide is Symptoms and Signs. It explains what changes or medical problems oral or oropharyngeal cancer can cause. Use the menu to choose a different section to read in this guide.

Oral and Oropharyngeal Cancer - Symptoms and Signs

Approved by the Cancer.Net Editorial Board, 10/2022

ON THIS PAGE: You will find out more about body changes and other things that can signal a problem that may need medical care. Use the menu to see other pages.

People with oral or oropharyngeal cancer may experience the following symptoms or signs. Symptoms are changes that you can feel in your body. Signs are changes in something measured, like by taking your blood pressure or doing a lab test. Together, symptoms and signs can help describe a medical problem. Sometimes, people with oral or oropharyngeal cancer do not have any of the signs and symptoms described below. Or, the cause of a symptom or sign may be a medical condition that is not cancer. Often, a dentist is the first person to find oral or oropharyngeal cancer during a routine examination.

  • The most common symptom is a sore in the mouth or on the lip that does not heal

  • Red or white patch on the gums, tongue, tonsil, or lining of the mouth

  • Lump on the lip, mouth, neck, or throat or a feeling of thickening in the cheek

  • Persistent sore throat or feeling that something is caught in the throat

  • Hoarseness or change in voice

  • Numbness of the mouth or tongue

  • Pain or bleeding in the mouth

  • Difficulty chewing, swallowing, or moving the jaws or tongue

  • Ear and/or jaw pain

  • Chronic bad breath

  • Changes in speech

  • Loosening of teeth or toothache

  • Dentures that no longer fit

  • Unexplained weight loss

  • Fatigue

  • During later stages of the disease, people may experience a loss of appetite

If you are concerned about any changes you experience, please talk with your doctor and/or dentist as soon as possible. Your doctor will ask how long and how often you’ve been experiencing the symptom(s), in addition to other questions. This is to help figure out the cause of the problem, called a diagnosis.

If cancer is diagnosed, relieving symptoms remains an important part of cancer care and treatment. Managing symptoms may also be called palliative care or supportive care. It is often started soon after diagnosis and continued throughout treatment. Be sure to talk with your health care team about the symptoms you experience, including any new symptoms or a change in symptoms.

The next section in this guide is Diagnosis. It explains what tests may be needed to learn more about the cause of the symptoms. Use the menu to choose a different section to read in this guide.

Oral and Oropharyngeal Cancer - Diagnosis

Approved by the Cancer.Net Editorial Board, 10/2022

ON THIS PAGE: You will find a list of common tests, procedures, and scans that doctors use to find the cause of a medical problem. Use the menu to see other pages.

Doctors use many tests to find, or diagnose, cancer. They also do tests to learn if cancer has spread to another part of the body from where it started. If the cancer has spread, it is called metastasis. Imaging tests show pictures of the inside of the body. Doctors may also do tests to learn which treatments could work best.

For most types of cancer, a biopsy is the only sure way for the doctor to know if an area of the body has cancer. In a biopsy, the doctor takes a small sample of tissue for testing in a laboratory. If a biopsy is not possible, the doctor may suggest other tests that will help make a diagnosis.

How oral or oropharyngeal cancer is diagnosed

There are many tests used for diagnosing oral or oropharyngeal cancer. Not all tests described here will be used for every person. Your doctor may consider these factors when choosing a diagnostic test:

  • The type of cancer suspected

  • Your signs and symptoms

  • Your age and general health

  • The results of earlier medical tests

The following tests may be used to diagnose oral or oropharyngeal cancer:

  • Physical examination. Dentists and doctors often find lip and oral cavity cancers during routine checkups. If a person shows signs of oral or oropharyngeal cancer, the doctor will take a complete medical history, asking about the patient’s symptoms and risk factors. The doctor will feel for any lumps on the neck, lips, gums, and cheeks. Because people with oral or oropharyngeal cancer have a higher risk of other cancers elsewhere in the head and neck region, the doctor will examine the area behind the nose, the larynx (voice box), and the lymph nodes of the neck.

  • Endoscopy. An endoscopy allows the doctor to see inside the mouth and throat. Typically, a thin, flexible tube with an attached light and view lens, called an endoscope, is inserted through the nose to examine the head and neck areas. Sometimes, a rigid endoscope, which is a hollow tube with a light and view lens, is placed into the back of the mouth to see the back of the throat in more detail.

    Endoscopic examinations have different names depending on the area of the body that is examined, such as laryngoscopy to view the larynx, pharyngoscopy to view the pharynx, or nasopharyngoscopy to view the nasopharynx. To make the patient more comfortable, these examinations are performed using an anesthetic spray to numb the area. If an area looks suspicious, the doctor will take a biopsy (see below). Tests are often done in the doctor’s office. However, sometimes an endoscopy must be performed in an operating room at a hospital using general anesthesia, which blocks the awareness of pain.

  • Biopsy. A biopsy is the removal of a small amount of tissue for examination under a microscope. Other tests can suggest that cancer is present, but only a biopsy can make a definite diagnosis. The type of biopsy performed will depend on the location of the cancer. During a fine needle aspiration biopsy, cells are removed using a thin needle inserted directly into the suspicious area. A pathologist then analyzes the cells. A pathologist is a doctor who specializes in interpreting laboratory tests and evaluating cells, tissues, and organs to diagnose disease.

  • Oral brush biopsy. During routine dental examinations, some dentists are using a newer, simple technique to detect oral cancer in which the dentist uses a small brush to gather cell samples of a suspicious area. The specimen is then sent to a laboratory for analysis. This procedure can be done in the dentist’s chair with very little or no pain. If cancer is found using this method, a traditional biopsy is recommended to confirm the results.

  • HPV testing. HPV testing may be done on a sample of the tumor removed during the biopsy. As described in Risk Factors and Prevention, HPV has been linked to a higher risk of oropharyngeal cancer. Knowing if a person has HPV can help determine the cancer’s stage and the treatment options that are likely to be most effective. ASCO recommends that HPV testing is done for all patients newly diagnosed with oropharyngeal squamous cell carcinoma. This is a type of oropharyngeal cancer that starts in flat, scale-like cells called squamous cells. Testing is not usually recommended for oropharyngeal cancer that starts in other types of cells or for other types of head and neck cancer. Learn more details about recommendations for HPV testing on a separate ASCO website.

  • X-ray. An x-ray is a way to create a picture of the structures inside of the body, using a small amount of radiation. X-rays may be recommended by your dentist or doctor to look for abnormal findings in the mouth or neck.

  • Barium swallow/modified barium swallow. There are 2 barium swallow tests that are generally used to look at the oropharynx and to check a patient’s swallowing. The first is a traditional barium swallow. During an x-ray exam, the patient is asked to swallow liquid barium. This lets the doctor look for any changes in the structure of the oral cavity and throat and see whether the liquid passes easily to the stomach. A modified barium swallow, or videofluoroscopy, may be used to evaluate difficulties with swallowing.

  • Computed tomography (CT or CAT) scan. A CT scan takes pictures of the inside of the body using x-rays taken from different angles. A computer combines these pictures into a detailed, 3-dimensional image that shows any abnormalities or tumors. A CT scan can be used to measure the tumor’s size, help the doctor decide whether the tumor can be surgically removed, and show whether the cancer has spread to lymph nodes in the neck or lower jawbone. Sometimes, a special dye called a contrast medium is given before the scan to provide better detail on the image. This dye can be injected into a patient’s vein or given as a pill or liquid to swallow.

  • Magnetic resonance imaging (MRI). An MRI uses magnetic fields, not x-rays, to produce detailed images of the body, especially images of soft tissue, such as the tonsils and the base of the tongue. MRI can be used to measure the tumor’s size. A special dye called a contrast medium is given before the scan to create a clearer picture. This dye can be injected into a patient’s vein or given as a pill or liquid to swallow.

  • Ultrasound. An ultrasound uses sound waves to create a picture of the internal organs. This test can detect the spread of cancer to the lymph nodes in the neck, which doctors also call the "cervical lymph nodes."

  • Positron emission tomography (PET) or PET-CT scan. A PET scan is usually combined with a CT scan (see above), called a PET-CT scan. However, you may hear your doctor refer to this procedure just as a PET scan. A PET scan is a way to create pictures of organs and tissues inside the body. A small amount of a radioactive sugar substance is injected into the patient’s body. This sugar substance is taken up by cells that use the most energy. Because cancer tends to use energy actively, it absorbs more of the radioactive substance. However, the amount of radiation in the substance is too low to be harmful. A scanner then detects this substance to produce images of the inside of the body.

After diagnostic tests are done, your doctor will review the results with you. If the diagnosis is cancer, these results also help the doctor describe the cancer. This is called staging.

The next section in this guide is Stages and Grades. It explains the system doctors use to describe the extent of the cancer. Use the menu to choose a different section to read in this guide.

Oral and Oropharyngeal Cancer - Stages and Grades

Approved by the Cancer.Net Editorial Board, 10/2022

ON THIS PAGE: You will learn about how doctors describe a cancer’s growth or spread. This is called the stage. Use the menu to see other pages.

What is cancer staging?

Staging is a way of describing where a cancer is located, if or where it has spread, and whether it is affecting other parts of the body.

Doctors use diagnostic tests to find out the cancer’s stage, so staging may not be complete until all the tests are finished. Knowing the stage helps the doctor recommend the best kind of treatment, and can help predict a patient’s prognosis, which is the chance of recovery. There are different stage descriptions for different types of cancer.

This page provides detailed information about the system used to find the stage of oral and oropharyngeal cancer and the cancer stage grouping for oral and oropharyngeal cancer, such as stage II or stage IV.

TNM staging system

One tool that doctors use to describe the stage is the TNM system. Doctors use the results from diagnostic tests and scans to answer these questions:

  • Tumor (T): How large is the primary tumor? Where is it located?

  • Node (N): Has the tumor spread to the lymph nodes? If so, where and how many?

  • Metastasis (M): Has the cancer spread to other parts of the body? If so, where and how much?

The TNM system differs depending whether the diagnosis is oral cancer, oropharyngeal cancer, or HPV-related oropharyngeal cancer.

The results of the TNM system are combined to determine the stage of cancer for each person. There are 4 or 5 stages, depending on the diagnosis. Stage 0 (zero) is only used for non-HPV-related oropharyngeal cancer. Stages I through IV (1 through 4) are used for all types of oral and oropharyngeal cancers. The stage provides a common way of describing the cancer, so doctors can work together to plan the best treatments.

Here are more details on each part of the TNM system for oral and oropharyngeal cancers.

Tumor (T)

Using the TNM system, the "T" plus a letter or number (0 to 4) is used to describe the size and location of the tumor. Tumor size is measured in millimeters (mm) and centimeters (cm). A centimeter is roughly equal to the width of a standard pen or pencil. There are 10 millimeters in 1 centimeter.

Stage may also be divided into smaller groups that help describe the tumor in even more detail. Specific tumor stage information is listed below.

Oral cavity cancer

TX: The primary tumor cannot be evaluated.

Tis: Describes a stage called carcinoma (cancer) in situ. This is a very early cancer where cancer cells are found only in 1 layer of tissue.

T1: The tumor is 2 cm or less at its greatest dimension. The tumor has invaded nearby tissues to a depth of 5 mm or less; this is called depth of invasion.

T2: The tumor is 2 cm or smaller, and the depth of invasion is more than 5 mm. Or, the tumor is larger than 2 cm but not larger than 4 cm, and the depth of invasion is 10 mm or less.

T3: The tumor is larger than 2 cm but not larger than 4 cm, and the depth of invasion is more than 10 mm. Or, the tumor is larger than 4 cm with a depth of invasion 10 mm or less.

T4: This is moderately advanced or very advanced local disease.

  • T4a (lip): The tumor began on the lip but has invaded bone or spread to the inferior alveolar nerve in the mouth, the floor of the mouth, or the skin of the face.

  • T4a (oral cavity): The tumor is larger than 4 cm, and the depth of invasion is more than 10 mm. Or, the tumor has invaded nearby structures in the mouth, such as the jaw, sinuses, or skin of the face.

  • T4b: The tumor has invaded the muscles and bones that form the mouth or the base of the skull, and/or it encases the internal arteries.

Oropharynx cancer (unrelated to HPV)

TX: The primary tumor cannot be evaluated.

Tis: Describes a stage called carcinoma (cancer) in situ. This is a very early cancer where cancer cells are found only in 1 layer of tissue.

T1: The tumor is 2 cm or smaller at its greatest dimension.

T2: The tumor is larger than 2 cm but not larger than 4 cm.

T3: The tumor is larger than 4 cm or has spread to the epiglottis, which is the flap of cartilage that diverts food into the esophagus.

T4a: The tumor has invaded the larynx, muscle of the tongue, muscles in the jaw, roof of the mouth, or jawbone.

T4b: The tumor has invaded muscles and bones in the region of the mouth; the nasopharynx, which is the air passageway at the upper part of the throat behind the nose; or the base of the skull, or the tumor encases the carotid artery.

HPV-related oropharyngeal cancer

T0 (T zero): No tumor can be found.

T1: The tumor is 2 cm or smaller at its greatest dimension.

T2: The tumor is larger than 2 cm but not larger than 4 cm.

T3: The tumor is larger than 4 cm or has spread to the epiglottis, which is the flap of cartilage that keeps food from entering the airway during swallowing.

T4: The tumor has invaded the larynx, muscle of the tongue, muscles in the jaw, roof of the mouth, or jawbone.

Node (N)

The “N” in the TNM staging system stands for lymph nodes. These small, bean-shaped organs help fight infection. Lymph nodes near where the cancer started are called regional lymph nodes. Lymph nodes in other parts of the body are called distant lymph nodes. There are many lymph nodes in the head and neck area. Careful assessment of lymph nodes is an important part of staging.

When cancer has spread through a lymph node and into the tissues directly surrounding it, it is called extranodal extension (ENE). Knowing whether ENE is present plays an important role in the evaluation of lymph nodes in oral and oropharyngeal cancers that are not related to HPV.

There are 2 methods of categorizing N in the TNM system: clinical and pathological. "Clinical N" is used for patients who have not received a neck dissection (see “Surgery” in Types of Treatment). "Pathological N" is used for those who have had a lymph node dissection.

Oral cavity and oropharynx cancers (unrelated to HPV) — Clinical N

NX: The regional lymph nodes cannot be evaluated.

N0 (N zero): There is no evidence of cancer in the regional lymph nodes.

N1: The cancer has spread to a single lymph node on the same side as the primary tumor, and the cancer found in the node is 3 cm or smaller. There is no ENE.

N2a: Cancer has spread to a single lymph node on the same side as the primary tumor and is larger than 3 cm but not larger than 6 cm. There is no ENE.

Recurrent oral and oropharyngeal cancer

Recurrent cancer is cancer that has come back after treatment. If the cancer does return, there will be another round of tests to learn about the extent of the recurrence. These tests and scans are often similar to those done at the time of the original diagnosis.

Return to top

Grade (G)

Doctors also describe oral and oropharyngeal cancers using a grade (G). The grade describes how much cancer cells look like healthy cells when viewed under a microscope. The grading system is for all oral and oropharyngeal cancers. HPV-related oropharyngeal cancer does not have a separate grading system.

The doctor compares the cancerous tissue with healthy tissue. Healthy tissue usually contains many different types of cells grouped together. If the cancer looks similar to healthy tissue and has different cell groupings, it is called "differentiated" or a "low-grade tumor." If the cancerous tissue looks very different from healthy tissue, it is called "poorly differentiated" or a "high-grade tumor." The cancer’s grade can help the doctor predict how quickly the cancer will spread. In general, the lower the tumor’s grade, the better the prognosis.

GX: The grade cannot be evaluated.

G1: The cells look more like normal tissue and are well differentiated.

G2: The cells are only moderately differentiated.

G3 and G4: The cells do not resemble normal tissue and are poorly differentiated.

Oral and Oropharyngeal Cancer - Types of Treatment

Approved by the Cancer.Net Editorial Board, 10/2022

ON THIS PAGE: You will learn about the different types of treatments doctors use to treat people with oral or oropharyngeal cancer. Use the menu to see other pages.

This section explains the types of treatments, also known as therapies, that are the standard of care for oral and oropharyngeal cancers. “Standard of care” means the best treatments known. When making treatment plan decisions, you are encouraged to discuss with your doctor whether clinical trials are an option. A clinical trial is a research study that tests a new approach to treatment. Doctors learn through clinical trials whether a new treatment is safe, effective, and possibly better than the standard treatment. Clinical trials can test a new drug, a new combination of standard treatments, or new doses of standard drugs or other treatments. Clinical trials are an option for all stages of cancer. Your doctor can help you consider all your treatment options. Learn more about clinical trials in the About Clinical Trials and Latest Research sections of this guide.

How oral and oropharyngeal cancers are treated

Oral and oropharyngeal cancers can often be cured, especially if the cancer is found at an early stage. Although curing the cancer is the primary goal of treatment, preserving the function of the nearby nerves, organs, and tissues is also very important. When doctors plan treatment, they consider how treatment might affect a person’s quality of life, such as how the person feels, looks, talks, eats, and breathes.

In many cases, a team of doctors will work together with the patient to create the best treatment plan. Head and neck cancer specialists often form a multidisciplinary team to care for each patient. This team may include:

  • Medical oncologist: A doctor who treats cancer using chemotherapy or other medications, such as targeted therapy and immunotherapy.

  • Radiation oncologist: A doctor who specializes in treating cancer using radiation therapy.

  • Surgical oncologist: A doctor who treats cancer using surgery.

  • Otolaryngologist: A doctor who specializes in the ear, nose, and throat.

  • Reconstructive/plastic surgeon: A doctor who specializes in reconstructive surgery, which is done to help repair damage caused by cancer treatment.

  • Maxillofacial prosthodontist: A specialist who performs restorative surgery in the head and neck areas.

  • Oncologic dentist or oral oncologist: Dentists experienced in caring for people with head and neck cancer.

  • Prosthodontist: A dental specialist with expertise in the restoration and replacement of broken teeth with crowns, bridges, or dentures.

  • Physical therapist: A health care professional who helps patients improve their physical strength and ability to move.

  • Speech-language pathologist: A health care professional who specializes in communication and swallowing disorders. A speech-language pathologist helps patients regain their speaking, swallowing, and oral motor skills after cancer treatment that affects the head, mouth, and neck.

  • Audiologist: A health care professional who treats and manages hearing problems that may be caused by the tumor itself or the cancer treatment.

  • Psychologist/psychiatrist: These mental health professionals address the emotional, psychological, and behavioral needs of the person with cancer and those of their family.

Cancer care teams include a variety of other health care professionals, such as physician assistants, nurse practitioners, oncology nurses, social workers, pharmacists, counselors, dietitians, and others. It is extremely important for the team to create a comprehensive treatment plan before treatment begins. People may need to be seen by several specialists before a treatment plan is fully developed.

Treatment options and recommendations depend on several factors, including the type and stage of cancer, possible side effects, and the patient’s preferences and overall health. One of these therapies, or a combination of them, may be used.

Take time to learn about all of your treatment options and be sure to ask questions about things that are unclear. Talk with your doctor about the goals of each treatment and what you can expect while receiving the treatment. These types of talks are called “shared decision-making.” Shared decision-making is when you and your doctors work together to choose treatments that fit the goals of your care. Shared decision-making is particularly important for oral and oropharyngeal cancers because there are different treatment options. Learn more about making treatment decisions.

There are 3 main treatment options for oral and oropharyngeal cancer: surgery, radiation therapy, and therapies using medication. These types of treatment are described below. Your care plan may also include treatment for symptoms and side effects, an important part of cancer care.

Surgery

Surgery is the removal of the tumor and some surrounding healthy tissue, known as a margin, during an operation. An important goal of the surgery is the complete removal of the tumor with "negative margins." Negative margins means that there is no trace of cancer in the margin's healthy tissue. Surgeons are often able to tell in the operating room if all of the tumor has been removed.

Sometimes surgery is followed by radiation therapy, therapies using medication, or both. Depending on the location, stage, grade, and other features of the cancer, some people may need more than 1 operation to remove the cancer and to help restore the appearance and function of the affected tissues.

The most common surgical procedures for the removal of oral or oropharyngeal cancer include:

  • Primary tumor surgery. The tumor and a margin of healthy tissue around it are removed to decrease the chance that any cancerous cells will be left behind. The tumor may be removed through the mouth or through an incision in the neck. A mandibulotomy, in which the jawbone is split to allow the surgeon to reach the tumor, may also be required.

  • Glossectomy. This is the partial or total removal of the tongue.

  • Mandibulectomy. If the tumor has entered a jawbone but not spread into the bone, then a piece of the jawbone or the whole jawbone will be removed. If there is evidence of destruction of the jawbone on an x-ray, then the entire bone may need to be removed.

  • Maxillectomy. This surgery removes part or all of the hard palate, which is the bony roof of the mouth. Prostheses (an artificial replacement), or more recently, the use of flaps of soft tissue with and without bone can be placed to fill gaps created during this operation.

  • Neck dissection. Cancer of the oral cavity or oropharynx often spreads to lymph nodes in the neck. Preventing the cancer from spreading to the lymph nodes is an important goal of treatment. It may be necessary to remove some or all of these lymph nodes using a surgical procedure called a neck dissection, even if the lymph nodes show no evidence of cancer when examined (see Stages and Grades). A neck dissection may be followed by radiation therapy or a combination of chemotherapy and radiation therapy, called chemoradiation, to make sure there is no cancer remaining in the lymph nodes. Sometimes, for oropharyngeal cancer, a neck dissection will be recommended after radiation therapy or chemoradiation. If a neck dissection is not possible, radiation therapy may be used instead. See "Radiation therapy," below, for more details on this type of treatment.

  • Laryngectomy. A laryngectomy is the complete or partial removal of the larynx or voice box. Although the larynx is important for producing sounds, the larynx is also critical to swallowing because it protects the airway from food and liquid entering the trachea or windpipe and reaching the lungs, which can cause pneumonia. A laryngectomy is rarely needed to treat oral or oropharyngeal cancer. However, when there is a large tumor of the tongue or oropharynx, the doctor may need to remove the larynx to protect the airway during swallowing. If the larynx is removed, the windpipe is reattached to the skin of the neck where a hole, called a stoma or tracheostomy, is made (see below). Rehabilitation will be needed to learn a new way of speaking (see Follow-up Care).

  • Transoral robotic surgery and transoral laser microsurgery. Transoral robotic surgery (TORS) and transoral laser microsurgery (TLM) are minimally invasive surgical procedures. This means that they do not require large cuts to get to and remove a tumor. In TORS, an endoscope is used to see a tumor in the throat, the base of the tongue, and the tonsils. Then 2 small robotic instruments act as the surgeon’s arms to remove the tumor. In TLM, an endoscope connected to a laser is inserted through the mouth. The laser is then used to remove the tumor. A laser is a narrow beam of high-intensity light.

Other types of surgery may also be needed, including:

  • Micrographic surgery. This type of surgery is frequently used to treat skin cancer and can sometimes be used for oral cavity tumors. It can reduce the amount of healthy tissue removed. This technique is often used with cancer of the lip. It involves removing the visible tumor in addition to small fragments of tissue surrounding the tumor. Each small fragment is examined under a microscope until all of the cancer has been removed.

  • Tracheostomy. If cancer is blocking the airway or is too large to completely remove, a hole is made in the neck. This hole is called a tracheostomy. A tracheostomy tube is then placed, and a person breathes through this tube. A tracheostomy can be temporary or permanent.

  • Gastrostomy tube. If cancer prevents a person from swallowing, a feeding device called a gastrostomy tube is placed. The tube goes through the skin and muscle of the abdomen and directly into the stomach. These tubes may be used as a temporary method for maintaining nutrition until the person can safely and adequately swallow food taken in through the mouth. For swallowing problems that are temporary, a nasogastric (NG) tube may be used instead of a tube into the stomach. An NG tube is inserted through the nose, down the esophagus, and into the stomach.

  • Reconstruction. If treatment requires removing large areas of tissue, reconstructive surgery may be necessary to help the patient swallow and speak again. Healthy bone or tissue may be taken from other parts of the body to fill gaps left by the tumor or replace part of the lip, tongue, palate, or jaw. A prosthodontist may be able to make an artificial dental or facial part to help with swallowing and speech. A speech-language pathologist can teach the patient to communicate using new techniques or special equipment and can also help restore the ability to swallow in patients who have difficulty eating after surgery or after radiation therapy. Learn more about the basics of reconstructive surgery.

In general, surgery for oral and oropharyngeal cancer often causes swelling, making it difficult to breathe. It may cause permanent loss of voice or impaired speech; difficulty chewing, swallowing, or talking; numbness of the ear; weakness raising the arms above the head; lack of movement in the lower lip; and changes to your facial appearance. Surgery can affect the function of the thyroid gland, especially after a total laryngectomy or radiation therapy to the area. Talk with your surgeon about the possible side effects from your specific surgery in advance and how they will be managed or relieved.

It is important that a person receive the opinion of different members of the multidisciplinary team before deciding on a specific treatment. Even though surgery is the fastest way to remove cancer, other treatment methods exist and may be equally effective in treating the cancer. You are encouraged to ask about all of the treatment options before deciding on a treatment plan.

Talk with your health care team before surgery, so you know what to expect and how your side effects will be managed. Learn more about the basics of cancer surgery.

Radiation therapy

Radiation therapy is the use of high-energy x-rays or other particles to destroy cancer cells. A radiation therapy regimen, or schedule, usually consists of a specific number of treatments given over a set period of time.

  • External-beam radiation therapy. This is the most common type of radiation treatment for oral or oropharyngeal cancer. During external-beam radiation therapy, a radiation beam produced by a machine outside the body is aimed at the tumor. This is generally done as an outpatient procedure, meaning the patient comes into the center for treatment then returns home after each session.

    Proton therapy is a type of external-beam radiation therapy that uses protons rather than x-rays. At high energy, protons can destroy cancer cells. Another method of external-beam radiation therapy, known as intensity modulated radiation therapy (IMRT), allows for more effective doses of radiation therapy to be delivered to the tumor while reducing damage to healthy cells.

  • Internal radiation therapy. When radiation treatment is given using implants, it is called internal radiation therapy or brachytherapy. Tiny pellets or rods containing radioactive materials are surgically implanted in or near the cancer site. The implant is left in place for several days while the person stays in the hospital.

Radiation therapy may be the main treatment for oral cavity cancer, or it can be used after surgery to destroy small areas of cancer that could not be removed. Radiation therapy can also be used to treat the lymph nodes. Combining radiation therapy with cisplatin (a chemotherapy drug; see below) may be used for this purpose in some cases. This approach is called chemoradiation.

Before beginning radiation treatment for any head and neck cancer, people should receive a thorough examination from a dentist with experience treating people with head and neck cancer. Since radiation therapy can cause tooth decay, damaged teeth may need to be removed. Often, tooth decay can be prevented by proper treatment from a dentist before beginning treatment. Learn more about dental and oral health.

It is also important that people receive counseling and evaluation from an oncologic speech-language pathologist. This is a speech-language pathologist who has experience treating people with head and neck cancer. Because radiation therapy can damage healthy tissue, people often have difficulty speaking and/or swallowing after radiation therapy. These problems may occur long after radiation therapy is completed. Speech-language pathologists can provide exercises and techniques to prevent long-term speech and swallowing problems.

Hearing problems may affect patients who receive radiation therapy to the head due to nerve damage or buildup of fluid in the middle ear. Earwax may also dry out and build up because of the radiation therapy’s effect on the ear canal. Sometimes, a patient’s hearing ability may need to be evaluated by a hearing specialist, known as an audiologist.

Radiation therapy may also cause a thyroid problem called hypothyroidism. In this condition, the thyroid gland slows down, causing the patient to feel tired and sluggish. Every patient who receives radiation therapy to the neck area should have their thyroid function checked regularly.

Other side effects from radiation therapy to the head and neck may include redness or skin irritation to the treated area, dry mouth or thickened saliva from damage to salivary glands (which can be temporary or permanent), temporary swelling (called edema) or long-term swelling (called lymphedema), bone pain, nausea, fatigue, mouth sores, sore throat, difficulty opening the mouth, and a loss of appetite due to a change in a person’s sense of taste. Talk with your doctor about possible side effects that you can expect and ways to manage them.

Therapies using medication

The treatment plan may include medications used to destroy cancer cells. Medication may be given through the bloodstream to reach cancer cells throughout the body. When a drug is given this way, it is called systemic therapy. Medication may also be given locally, which is when the medication is applied directly to the cancer or kept in a single part of the body.

This treatment is generally prescribed by a medical oncologist, a doctor who specializes in treating cancer with medication. Medications are often given through an intravenous (IV) tube placed into a vein using a needle or as a pill or capsule that is swallowed (orally). If you are given oral medications, be sure to ask your health care team about how to safely store and handle them.

The types of medications used for oral and oropharyngeal cancer include:

  • Chemotherapy

  • Immunotherapy

  • Targeted therapy

Each of these types of therapies is discussed below in more detail. A person may receive 1 type of medication at a time or a combination of medications given at the same time. They can also be given as part of a treatment plan that includes surgery and/or radiation therapy.

The medications used to treat cancer are continually being evaluated. Talking with your doctor is often the best way to learn about the medications prescribed for you, their purpose, and their potential side effects or interactions with other medications.

It is also important to let your doctor know if you are taking any other prescription or over-the-counter medications or supplements. Herbs, supplements, and other drugs can interact with cancer medications, causing unwanted side effects or reduced effectiveness. Learn more about your prescriptions by using searchable drug databases.

Chemotherapy

Chemotherapy is the use of drugs to destroy cancer cells, usually by keeping the cancer cells from growing, dividing, and making more cells.

Some people may receive chemotherapy in their doctor's office or an outpatient clinic. Others may go to the hospital.

A chemotherapy regimen, or schedule, usually consists of a specific number of cycles given over a set period of time. A patient may receive 1 drug at a time or a combination of different drugs given at the same time.

The use of chemotherapy in combination with radiation therapy, called chemoradiation, is often recommended. The combination of these 2 treatments can sometimes control tumor growth, and it often is more effective than giving either of these treatments alone. This combined treatment, using cisplatin, may be an option for oral or oropharyngeal cancer that may have spread to the lymph nodes. Sometimes, chemoradiation for oropharyngeal cancer will be followed with neck dissection (see "Surgery," above). However, the side effects can be worse when combining these treatments.

Chemotherapy may be used as the initial treatment before surgery, radiation therapy, or both, which is called a neoadjuvant chemotherapy. Or it can be given after surgery, radiation therapy, or both, which is called adjuvant chemotherapy. Chemotherapy for oral cavity cancer is most often given as part of a clinical trial.

Each drug or combination of drugs can cause specific side effects. While some can be permanent, most are temporary and can typically be well controlled. In general, chemotherapy may cause fatigue, nausea, vomiting, hair loss, dry mouth, hearing loss, loss of appetite (often due to a change in sense of taste), difficulty eating food, weakened immune system, diarrhea, constipation, and open sores in the mouth that can lead to infection. Your health care team will help you understand what to expect with your prescriptions and how side effects can be managed.

Immunotherapy

Immunotherapy uses the body's natural defenses to fight cancer by improving your immune system's ability to attack cancer cells.

Pembrolizumab (Keytruda) and nivolumab (Opdivo) are 2 immunotherapy drugs approved by the U.S. Food and Drug Administration (FDA) for the treatment of people with recurrent or metastatic head and neck squamous cell carcinoma (HNSCC) that has not been stopped by platinum-based chemotherapy (see below for information on recurrent cancer and metastatic cancer). Both are immune checkpoint inhibitors that are also approved for the treatment of some people with advanced cancers of other kinds.

Immunotherapy in combination with chemotherapy and radiation therapy may also be used in clinical trials.

Different types of immunotherapy can cause different side effects. Common side effects include skin reactions, flu-like symptoms, diarrhea, and weight changes. Talk with your doctor about possible side effects for the immunotherapy recommended for you. Learn more about the basics of immunotherapy.

Return to top

Targeted therapy

Targeted therapy is a treatment that targets the cancer’s specific genes, proteins, or the tissue environment that contributes to cancer growth and survival. This type of treatment blocks the growth and spread of cancer cells and limits damage to healthy cells.

Not all tumors have the same targets. To find the most effective treatment, your doctor may run tests to identify the genes, proteins, and other factors in your tumor. This helps doctors better match each patient with the most effective treatment whenever possible. In addition, research studies continue to find out more about specific molecular targets and new treatments directed at them.

Currently, antibodies directed against a cellular receptor called the epidermal growth factor receptor (EGFR) are being used in combination with radiation therapy for head and neck cancers. Cetuximab (Erbitux) is a targeted therapy approved by the FDA for this use in combination with radiation therapy.

Talk with your doctor about the possible side effects of the specific treatment you will be receiving and how they can be managed.

Learn more about the basics of targeted treatments.

Physical, emotional, and social effects of cancer

Cancer and its treatment cause physical symptoms and side effects, as well as emotional, social, and financial effects. Managing all of these effects is called palliative care or supportive care. It is an important part of your care that is included along with treatments intended to slow, stop, or eliminate the cancer.

Palliative care focuses on improving how you feel during treatment by managing symptoms and supporting patients and their families with other, non-medical needs. Any person, regardless of age or type and stage of cancer, may receive this type of care. And it often works best when it is started right after a cancer diagnosis. People who receive palliative care along with treatment for the cancer often have less severe symptoms, better quality of life, and report that they are more satisfied with treatment.

Palliative treatments vary widely and often include medication, nutritional changes, relaxation techniques, emotional and spiritual support, and other therapies. You may also receive palliative treatments similar to those meant to get rid of the cancer, such as chemotherapy, surgery, or radiation therapy.

Before treatment begins, talk with your doctor about the goals of each treatment in the recommended treatment plan. You should also talk about the possible side effects of the specific treatment plan and palliative care options. Many patients also benefit from talking with a social worker and participating in support groups. Ask your doctor about these resources, too.

During treatment, your health care team may ask you to answer questions about your symptoms and side effects and to describe each problem. Be sure to tell the health care team if you are experiencing a problem. This helps the health care team treat any symptoms and side effects as quickly as possible. It can also help prevent more serious problems in the future.

Learn more about the importance of tracking side effects in another part of this guide. Learn more about palliative care in a separate section of this website.

Metastatic cancer

If cancer spreads to another part in the body from where it started, doctors call it metastatic cancer. If this happens, it is a good idea to talk with doctors who have experience in treating it. Doctors can have different opinions about the best standard treatment plan. Clinical trials might also be an option. Learn more about getting a second opinion before starting treatment, so you are comfortable with your chosen treatment plan.

Your treatment plan may include a combination of surgery, radiation therapy, chemotherapy, targeted therapy, or immunotherapy. Palliative care will also be important to help relieve symptoms and side effects.

For most people, a diagnosis of metastatic oral or oropharyngeal cancer is very stressful and difficult. You and your family are encouraged to talk about how you feel with doctors, nurses, social workers, or other members of your health care team. It may also be helpful to talk with other patients, such as through a support group or other peer support program.

Remission and the chance of recurrence

A remission is when cancer cannot be detected in the body and there are no symptoms. This may also be called having “no evidence of disease” or NED.

A remission may be temporary or permanent. This uncertainty causes many people to worry that the cancer will come back. While many remissions are permanent, it is important to talk with your doctor about the possibility of the cancer returning. Understanding your risk of recurrence and the treatment options may help you feel more prepared if the cancer does return. Learn more about coping with the fear of recurrence.

If the cancer returns after the original treatment, it is called recurrent cancer. It may come back in the same place (called a local recurrence), nearby (regional recurrence), or in another place (distant recurrence).

If a recurrence happens, a new cycle of testing will begin again to learn as much as possible about it. After this testing is done, you and your doctor will talk about the treatment options. Often the treatment plan will include the treatments described above, such as surgery, medications, and radiation therapy, but they may be used in a different combination or given at a different pace. Your doctor may suggest clinical trials that are studying new ways to treat recurrent oral and oropharyngeal cancer. Whichever treatment plan you choose, palliative care will be important for relieving symptoms and side effects.

People with recurrent cancer sometimes experience emotions such as disbelief or fear. You are encouraged to talk with your health care team about these feelings and ask about support services to help you cope. Learn more about dealing with cancer recurrence.

If treatment does not work

Recovery from cancer is not always possible. If the cancer cannot be cured or controlled, the disease may be called advanced or terminal.

This diagnosis is stressful, and for some people, advanced cancer is difficult to discuss. However, it is important to have open and honest conversations with your doctor and health care team to express your feelings, preferences, and concerns. The health care team has special skills, experience, and knowledge to support patients and their families and is there to help. Making sure a person is physically comfortable, free from pain, and emotionally supported is extremely important.

People who have advanced cancer and who are expected to live less than 6 months may want to consider hospice care. Hospice care is designed to provide the best possible quality of life for people who are near the end of life. You and your family are encouraged to talk with the health care team about hospice care options, which include hospice care at home, a special hospice center, or other health care locations. Nursing care and special equipment can make staying at home a workable option for many families. Learn more about advanced cancer care planning.

After the death of a loved one, many people need support to help them cope with the loss. Learn more about grief and loss.

Oral and Oropharyngeal Cancer - About Clinical Trials

Approved by the Cancer.Net Editorial Board, 10/2022

ON THIS PAGE: You will learn more about clinical trials, which are the main way that new medical approaches are studied to see how well they work. Use the menu to see other pages.

What are clinical trials?

Doctors and scientists are always looking for better ways to care for people with oral or oropharyngeal cancer. To make scientific advances, doctors create research studies involving volunteers, called clinical trials. Every drug that is now approved by the U.S. Food and Drug Administration (FDA) was tested in clinical trials.

Clinical trials are used for all types and stages of oral and oropharyngeal cancers. Many focus on new treatments to learn if a new treatment is safe, effective, and possibly better than the existing treatments. These types of studies evaluate new drugs, different combinations of treatments, new approaches to radiation therapy or surgery, and new methods of treatment.

People who participate in clinical trials can be some of the first to get a treatment before it is available to the public. However, there are some risks with a clinical trial, including possible side effects and the chance that the new treatment may not work. People are encouraged to talk with their health care team about the pros and cons of joining a specific study.

Some clinical trials study new ways to relieve symptoms and side effects during treatment. Others study ways to manage the late effects that may happen a long time after treatment. Talk with your doctor about clinical trials for symptoms and side effects.

Deciding to join a clinical trial

People decide to participate in clinical trials for many reasons. For some, a clinical trial is the best treatment option available. Because standard treatments are not perfect, patients are often willing to face the added uncertainty of a clinical trial in the hope of a better result. Others volunteer for clinical trials because they know that these studies are a way to contribute to the progress in treating head and neck cancer. Even if they do not benefit directly from the clinical trial, their participation may benefit future people with oral or oropharyngeal cancer.

Insurance coverage and the costs of clinical trials differ by location and by study. In some programs, some of the expenses from participating in the clinical trial are reimbursed. In others, they are not. It is important to talk with the research team and your insurance company first to learn if and how your treatment in a clinical trial will be covered. Learn more about health insurance coverage of clinical trials.

Sometimes people have concerns that, in a clinical trial, they may receive no treatment by being given a placebo or a “sugar pill.” When used, placebos are usually combined with standard treatment in most cancer clinical trials. Study participants will always be told when a placebo is used in a study. Find out more about placebos in cancer clinical trials.

Patient safety and informed consent

To join a clinical trial, people must participate in a process known as informed consent. During informed consent, the doctor should:

  • Describe all of the treatment options, so that the person understands how the new treatment differs from the standard treatment.

  • List all of the risks of the new treatment, which may or may not be different than the risks of standard treatment.

  • Explain what will be required of each person in order to participate in the clinical trial, including the number of doctor visits, tests, and the schedule of treatment.

  • Describe the purposes of the clinical trial and what researchers are trying to learn.

Clinical trials also have certain rules called “eligibility criteria” that help structure the research and keep patients safe. You and the research team will carefully review these criteria together. You will need to meet all of the eligibility criteria in order to participate in a clinical trial. Learn more about eligibility criteria in clinical trials.

People who participate in a clinical trial may stop participating at any time for personal or medical reasons. This may include that the new treatment is not working or there are serious side effects. Clinical trials are also closely monitored by experts who watch for any problems with each study. It is important that people participating in a clinical trial talk with their doctor and researchers about who will be providing their treatment and care during the clinical trial, after the clinical trial ends, and/or if they choose to leave the clinical trial before it ends.

Finding a clinical trial

Research through clinical trials is ongoing for all types of cancer. For specific topics being studied for oral and oropharyngeal cancers, learn more in the Latest Research section.

Cancer.Net offers more of information about cancer clinical trials in other areas of the website, including a complete section on clinical trials and places to search for clinical trials for a specific type of cancer.

Oral and Oropharyngeal Cancer - Latest Research

Approved by the Cancer.Net Editorial Board, 10/2022

ON THIS PAGE: You will read about the scientific research being done to learn more about oral and oropharyngeal cancers and how to treat them. Use the menu to see other pages.

Doctors are working to learn more about oral and oropharyngeal cancers, ways to prevent them, how to best treat them, and how to provide the best care to people diagnosed with these diseases. The following areas of research may include new options for patients through clinical trials. Always talk with your doctor about the best diagnostic and treatment options for you.

  • New drug therapies. Many new treatments have become available as doctors and researchers have learned more about the biology of head and neck cancers. Some of these treatments, including immunotherapy and targeted therapy, are available through clinical trials. As described in Types of Treatment, immunotherapy uses the body's natural defenses to fight cancer by improving your immune system's ability to attack cancer cells. Therapies being researched include tyrosine kinase inhibitors; antiangiogenic therapy, which prevents the growth of blood vessels needed for tumor growth; immune modulating approaches; and drugs that trigger cancer cell death. These and other treatment approaches are in various stages of research.

  • Radiofrequency thermal ablation (RFA). RFA uses heat to destroy cancer cells. It is a minimally invasive treatment option that may be useful for treating a localized tumor that cannot be removed with surgery.

  • Less intense treatment for HPV-related cancer. Many patients with HPV-related oropharyngeal cancer have an excellent prognosis after treatment. Providing these patients with less intense treatment can reduce long-term side effects without affecting survival. However, research is ongoing in this area and less intensive treatment is only recommended as part of a clinical trial. Learn more about ASCO’s clinical opinion on less intense treatment for HPV-related oropharyngeal cancer.

  • Palliative care/supportive care. Clinical trials are underway to find better methods of reducing the symptoms and side effects of current oral and oropharyngeal cancer treatments to improve comfort and quality of life for patients.

The next section in this guide is Coping with Treatment. It offers some guidance on how to cope with the physical, emotional, social, and financial changes that cancer and its treatment can bring. Use the menu to choose a different section to read in this guide.

Oral and Oropharyngeal Cancer - Coping with Treatment

Approved by the Cancer.Net Editorial Board, 10/2022

ON THIS PAGE: You will learn more about coping with the physical, emotional, social, and financial effects of cancer and its treatment. Use the menu to see other pages.

Every cancer treatment can cause side effects or changes to your body and how you feel. For many reasons, people do not experience the same side effects even when they are given the same treatment for the same type of cancer. This can make it hard to predict how you will feel during treatment. People who are being treated for head and neck cancer may find it helpful to reach out to support groups that specialize in helping people being treated for oral and oropharyngeal cancers.

As you prepare to start cancer treatment, it is normal to fear treatment-related side effects. It may help to know that your health care team will work to prevent and relieve side effects. This part of cancer treatment is called palliative care or supportive care. It is an important part of your treatment plan, regardless of your age or the stage of disease.

Coping with physical side effects

Common physical side effects from each treatment option for oral and oropharyngeal cancer are described in the Types of Treatment section. Learn more about side effects of cancer and its treatment, along with ways to prevent or control them. Changes to your physical health depend on several factors, including the cancer’s stage, the length and dose of treatment, and your general health.

Talk with your health care team regularly about how you are feeling. It is important to let them know about any new side effects or changes in existing side effects. If they know how you are feeling, they can find ways to relieve or manage your side effects to help you feel more comfortable and potentially keep any side effects from worsening.

You may find it helpful to keep track of your side effects so it is easier to talk about any changes with your health care team. Learn more about why tracking side effects is helpful.

Sometimes, side effects can last after treatment ends. Doctors call these long-term side effects. Side effects that occur months or years after treatment are called late effects. Treating long-term side effects and late effects is an important part of survivorship care. Learn more by reading the Follow-up Care section of this guide or talking with your doctor.

Coping with emotional and social effects

You can have emotional and social effects after a cancer diagnosis. This may include dealing with a variety of emotions, such as sadness, anxiety, or anger, or managing your stress level. Sometimes, people find it difficult to express how they feel to their loved ones. Some have found that talking to an oncology social worker, counselor, or member of the clergy can help them develop more effective ways of coping and talking about cancer.

You can also find coping strategies for emotional and social effects in a separate section of this website. This section includes many resources for finding support and information to meet your needs.

Coping with the costs of cancer care

Cancer treatment can be expensive. It is may be a source of stress and anxiety for people with cancer and their families. In addition to treatment costs, many people find they have extra, unplanned expenses related to their care. For some people, the high cost of medical care stops them from following or completing their cancer treatment plan. This can put their health at risk and may lead to higher costs in the future. Patients and their families are encouraged to talk about financial concerns with a member of their health care team. Learn more about managing financial considerations in a separate part of this website.

Coping with barriers to care

Some groups of people experience different rates of new cancer cases and experience different outcomes from their cancer diagnosis. These differences are called "cancer disparities." Disparities are caused in part by real-world barriers to quality medical care and social determinants of health, such as where a person lives and whether they have access to food and health care. Cancer disparities more often negatively affect racial and ethnic minorities, people with fewer financial resources, sexual and gender minorities (LGBTQ+), adolescent and young adult populations, older adults, and people who live in rural areas or other underserved communities.

If you are having difficulty getting the care you need, talk with a member of your health care team or explore other resources that help support medically underserved people.

Talking with your health care team about side effects

Before starting treatment, talk with your doctor about possible side effects. Ask:

  • Which side effects are most likely?

  • When are they likely to happen?

  • What can we do to prevent or relieve them?

  • When and who should we call about side effects?

Be sure to tell your health care team about any side effects that happen during treatment and afterward, too. Tell them even if you do not think the side effects are serious. This discussion should include physical, emotional, social, and financial effects of cancer.

Caring for a loved one with cancer

Family members and friends often play an important role in taking care of a person with oral or oropharyngeal cancer. This is called being a caregiver. Caregivers can provide physical, practical, and emotional support to the patient, even if they live far away. Being a caregiver can also be stressful and emotionally challenging. One of the most important tasks for caregivers is caring for themselves.

Caregivers may have a range of responsibilities on a daily or as-needed basis, including:

  • Providing support and encouragement

  • Talking with the health care team

  • Giving medications

  • Helping manage symptoms and side effects

  • Coordinating medical appointments

  • Providing a ride to and from appointments

  • Assisting with meals

  • Helping with household chores

  • Handling insurance and billing issues

A caregiving plan can help caregivers stay organized and help identify opportunities to delegate tasks to others. It may be helpful to ask the health care team how much care will be needed at home and with daily tasks during and after treatment. Use this 1-page fact sheet to help make a caregiving action plan. This free fact sheet is available as a PDF, so it is easy to print.

Learn more about caregiving or read the ASCO Answers Guide to Caring for a Loved One With Cancer in English or Spanish.

The next section in this guide is Follow-up CareIt explains the importance of checkups after you finish cancer treatment. Use the menu to choose a different section to read in this guide.

Oral and Oropharyngeal Cancer - Follow-Up Care

Approved by the Cancer.Net Editorial Board, 10/2022

ON THIS PAGE: You will read about your medical care after cancer treatment is completed and why this follow-up care is important. Use the menu to see other pages.

Care for people diagnosed with cancer does not end when active treatment has finished. Your health care team will continue to check that the cancer has not come back, manage any side effects, and monitor your overall health. This is called follow-up care.

Your follow-up care may include regular physical examinations, medical tests, or both. Doctors want to keep track of your recovery in the months and years ahead. A common follow-up schedule is every 2 months for the first year, every 4 months for the second year, every 6 months for the third year, and once a year after that.

People treated for oral or oropharyngeal cancer have a higher risk of developing a secondary cancer. If you smoke, you should be monitored for possible secondary cancers in the lung, esophagus, and the head and neck area. Researchers are studying the use of chemotherapy to prevent second cancers from developing, called chemoprevention. This may become a part of regular follow-up care for those treated for oral or oropharyngeal cancer.

Learn more about the importance of follow-up care.

Cancer rehabilitation

Rehabilitation is a major part of follow-up care after treatment for head and neck cancer. People may need physical therapy and speech and swallowing therapy. Palliative and supportive care to manage symptoms and maintain good nutrition during and after treatment may be recommended.

Depending on the size and location of the tumor and the type of cancer treatment used, a person may have problems with their ability to chew and move food through the digestive system. People who have been treated for oral or oropharyngeal cancer can have long-term swallowing problems. It is important that they continue to swallow their saliva and as much food as they are able throughout treatment to prevent these problems from developing. Special nutritional care and support is often needed during and immediately following treatment. Some people may need to learn new ways to eat or prepare foods differently. Working with a speech-language pathologist and a registered dietitian can help with these challenges. Listen to a podcast about managing eating challenges after treatment.

If the cancer treatment changes the oral cavity structures or limits movement, a patient’s ability to speak will be affected. Speech-language pathologists can help people work toward regaining their speech and swallowing functions.

People treated for oral or oropharyngeal cancer may look different, feel tired, and be unable to talk or eat the way they did before treatment. They may experience swelling in the area, called lymphedema. Some people experience depression. Be sure to talk with members of your health care team about your physical and emotional side effects regularly. They can help you adjust and connect you with support services.

Watching for recurrence

One goal of follow-up care is to check for a recurrence, which means that the cancer has come back. Cancer recurs because small areas of cancer cells may remain undetected in the body. Over time, these cells may increase in number until they show up on test results or cause signs or symptoms.

People treated for oral or oropharyngeal cancer should receive regular follow-up medical and dental examinations to check for signs of recurrent cancer or a new type of cancer. Most recurrences of oral and oropharyngeal cancer happen within the first 2 to 3 years after diagnosis, so follow-up visits will be more frequent in the years right after treatment.

During follow-up care, a doctor familiar with your medical history can give you personalized information about your risk of recurrence. Your doctor will ask specific questions about your health. Some people may have blood tests or imaging tests done as part of regular follow-up care, but testing recommendations depend on several factors, including the type and stage of cancer first diagnosed and the types of treatment given.

The anticipation before having a follow-up test or waiting for test results may add stress to you or a family member. This is sometimes called “scanxiety.” Learn more about how to cope with this type of stress.

Managing long-term and late side effects

Most people expect to have side effects when receiving treatment. However, it is often surprising to survivors that some side effects may linger beyond the treatment period. These are called long-term side effects. Other side effects called late effects may develop months or even years after treatment has ended. Long-term and late effects can include both physical and emotional changes.

Talk with your doctor about your risk of developing such side effects based on your diagnosis, your individual treatment plan, and your overall health. If you had a treatment known to cause specific late effects, you may have certain physical examinations, scans, or blood tests to help find and manage them.

Surgery and radiation therapy used to treat oral and oropharyngeal cancers can affect a person’s thyroid gland. If your thyroid gland could have been affected by treatment, then thyroid function tests should be part of your follow-up care to find out if thyroid hormone medication is needed.

Special dental care
may also be needed to manage or avoid long-term dental problems.

Keeping personal health records

You and your doctor should work together to develop a personalized follow-up care plan. Be sure to discuss any concerns you have about your future physical or emotional health. ASCO offers forms to help keep track of the cancer treatment you received and develop a survivorship care plan when treatment is completed.

This is also a good time to talk with your doctor about who will lead your follow-up care. Some survivors continue to see their oncologist, while others transition back to the care of their primary care doctor or another health care professional. This decision depends on several factors, including the type and stage of cancer, side effects, health insurance rules, and your personal preferences.

If a doctor who was not directly involved in your cancer care will lead your follow-up care, be sure to share your cancer treatment summary and survivorship care plan forms with them and with all future health care providers. Details about your cancer treatment are very valuable to the health care professionals who will care for you throughout your lifetime.

Oral and Oropharyngeal Cancer - Survivorship

Approved by the Cancer.Net Editorial Board, 10/2022

ON THIS PAGE: You will read about how to cope with challenges in everyday life after a cancer diagnosis. Use the menu to see other pages.

What is survivorship?

The word “survivorship” is complicated because it means different things to different people. Common definitions include:

  • Having no signs of cancer after finishing treatment.

  • Living with, through, and beyond cancer. According to this definition, cancer survivorship begins at diagnosis and continues during treatment and through the rest of a person's life.

For some, even the term "survivorship" does not feel right, and they prefer to use different language to describe and define their experience. Sometimes extended treatment will be used for months or years to manage or control cancer. Living with cancer indefinitely is not easy, and the health care team can help you manage the challenges that come with it. Everyone has to find their own path to name and navigate the changes and challenges that are the results of their cancer diagnosis and treatment.

Some people continue to receive cancer treatment for a long time to reduce the risk of recurrence or manage the cancer as a chronic disease. Learn more about received extended cancer treatment.

Survivors may experience a mixture of feelings, including joy, concern, relief, guilt, and fear. Some people say they appreciate life more after a cancer diagnosis and have gained a greater acceptance of themselves. Others become very anxious about their health and uncertain about coping with everyday life. Feelings of fear and anxiety may still occur as time passes, but these emotions should not be a constant part of your daily life. If they persist, be sure to talk with a member of your health care team.

Survivors may feel some stress when their frequent visits to the health care team end after completing treatment. Often, relationships built with the cancer care team provide a sense of security during treatment, and people miss this source of support. This may be especially true when new worries and challenges surface over time, such as any late effects of treatment, emotional challenges including fear of recurrence, sexual health and fertility concerns, and financial and workplace issues.

Every survivor has individual concerns and challenges. With any challenge, a good first step is being able to recognize your fears and talk about them. Effective coping requires:

  • Understanding the challenge you are facing

  • Thinking through solutions

  • Asking for and allowing the support of others

  • Feeling comfortable with the course of action you choose

Many survivors find it helpful to join an in-person support group or an online community of survivors. This allows you to talk with people who have had similar first-hand experiences. Other options for finding support include talking with a friend or member of your health care team, individual counseling, or asking for assistance at the learning resource center of the place where you received treatment.

A new perspective on your health

For many people, survivorship serves as a strong motivator to make lifestyle changes.

People recovering from oral or oropharyngeal cancer are encouraged to follow established guidelines for good health, such as not smoking, limiting alcohol, eating well, exercising regularly, and managing stress. Regular physical activity can help rebuild your strength and energy level. Your health care team can help you create an appropriate exercise plan based upon your needs, physical abilities, and fitness level. Learn more about making healthy lifestyle choices.

It is important to have recommended medical checkups and tests to take care of your health. Talk with your health care team to develop a survivorship care plan that is best for your needs.

Changing role of caregivers

Family members and friends may also go through periods of transition. A caregiver plays a very important role in supporting a person diagnosed with cancer, providing physical, emotional, and practical care on a daily or as-needed basis. Many caregivers become focused on providing this support, especially if the treatment period lasts for many months or longer.

However, as treatment is completed, the caregiver's role often changes. Eventually, the need for caregiving related to the cancer diagnosis will become much less or come to an end. Caregivers can learn more about adjusting to life after caregiving.
