ON THIS PAGE: You will learn about the different treatments doctors use for people with AdCC. Use the menu to see other pages.
This section tells you the treatments that are the standard of care for this type of cancer. “Standard of care” means the best treatments known. When making treatment plan decisions, patients are encouraged to consider clinical trials as an option. A clinical trial is a research study that tests a new approach to treatment. Doctors want to learn whether the 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. Your doctor can help you consider all your treatment options. To learn more about clinical trials, see the About Clinical Trials and Latest Research sections.
In cancer care, different types of doctors often work together to create a patient’s overall treatment plan that combines different types of treatments. This is called a multidisciplinary team. Cancer care teams include a variety of other health care professionals as well.
The team may include medical and radiation oncologists; surgeons; otolaryngologists, who are ear, nose, and throat doctors; plastic, or reconstruction, surgeons; maxillofacial prosthodontists, specialists who perform restorative surgery in the head and neck areas; dentists; physical therapists; speech pathologists; audiologists, or hearing experts; psychiatrists; nurses; dietitians; and social workers. It is extremely important that this team creates a comprehensive treatment plan before treatment begins, and people may need to be seen by several specialists before a treatment plan is fully developed.
Although eliminating the cancer is the primary goal of treatment, preserving the function of the nearby nerves, organs, and tissues is also very important. When planning treatment, doctors consider how it might affect a person’s quality of life, such as how a person feels, looks, talks, eats, and breathes.
Descriptions of the most common treatment options for AdCC are listed below. 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. You care plan may also include treatment for your symptoms and side effects, an important part of cancer care. 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. Learn more about making treatment decisions.
Surgery is the removal of the tumor and some surrounding healthy tissue during an operation.
Surgical removal of the tumor is the best treatment for AdCC as long as it can be done safely and is likely to have a good outcome. A surgical oncologist is a doctor who specializes in treating cancer using surgery. During surgery, the surgeon will remove the tumor and an area of healthy tissue surrounding it, called a margin. Surgery is considered the most successful if the margin removed during surgery is found to be “clean,” which means there is a minimum of 2 millimeters (mm) of cancer-free tissue surrounding the tumor. The extent of surgery will vary depending on the location of the tumor and the area of the body involved.
Because AdCC may frequently spread along nerves, the surgeon should examine and determine whether nerves are involved. Major nerves that are not involved should be identified and spared during surgery. Smaller branches of nerves should be analyzed to determine if the cancer has spread to the space surrounding the nerve. For a later-stage tumor or one that significantly involves nerves, the surgeon should remove as much of the tumor as possible while sparing the organs and functions of the face. These are difficult decisions to make. Talk with your doctor about how to find a surgeon with the necessary level of expertise, experience, and training to perform this type of surgery.
Side effects from surgery vary depending upon the surgical site. A concern with all surgeries of the parotid gland is that the surgery may damage facial nerves, which can cause the muscles in the face to droop. Sometimes, a facial nerve graft or other reconstructive procedure (plastic surgery) may be recommended to restore the function of the facial muscles after surgery to remove the tumor.
Before surgery, talk with your health care team about the possible side effects from the specific surgery you will have. Learn more about the basics of cancer surgery.
Occasionally, it is not possible to remove AdCC using surgery. This type of tumor is called inoperable. In these cases, your doctor will recommend other treatment options. See below for more information.
External-beam radiation therapy
Radiation therapy is the use of high-energy x-rays or other particles to destroy cancer cells. The most common type of radiation treatment is called external-beam radiation therapy, which is radiation given from a machine outside the body. A doctor who specializes in giving radiation therapy to treat cancer is called a radiation oncologist. A radiation therapy regimen, or schedule, usually consists of a specific number of treatments given over a set period.
Radiation therapy is particularly effective for AdCC as an adjuvant therapy by helping to eliminate any microscopic cancer cells that may remain in the body after surgery. Adjuvant therapy is therapy given after surgery. Radiation therapy is not used pre-operatively, meaning before surgery, for this disease. That is because many surgeons feel that the surgical wound heals better if radiation therapy is not given prior to surgery.
A specific method of external-beam radiation therapy, known as intensity modulated radiation therapy (IMRT), allows for more effective doses of radiation therapy to be delivered while reducing the damage to healthy cells and causing fewer side effects.
Since radiation therapy is targeted to a specific area, the side effects will depend on where the radiation therapy was given. Generally, during head and neck treatments, people may experience a sore mouth and/or throat that can cause pain and difficulty in swallowing. They may also have a skin reaction or burn that causes some pain.
Before beginning radiation treatment for any head and neck cancer, patients should receive a thorough examination from an oncologic dentist. An oncologic dentist is experienced in 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 with proper treatment from a dentist before beginning treatment. Learn more about dental and oral health during cancer treatment.
People should also receive an evaluation from a speech pathologist with experience treating people with head and neck cancer. The speech pathologist can teach exercises that will help maintain the strength and flexibility of the muscles used during speech and swallowing.
Long-term side effects of radiation therapy vary with the sites involved, but they may include permanent loss of saliva, causing dryness of the mouth and deterioration of the teeth. In some cases, a drug to stimulate the parotid salivary gland and increase or restore saliva levels may be given. Currently, amifostine (Ethyol), a drug to protect tissues during radiation therapy, is being studied. Scarring or fibrosis, which is the hardening or thickening of the skin and muscles, may develop several months to years after radiation therapy and lead to problems with wound healing, neck stiffness, and trouble swallowing. Other long-term effects that can develop include accelerated narrowing of the carotid arteries, which supply the head and neck with blood. There may also be lower thyroid gland functioning, called hypothyroidism, which can be managed with thyroid hormone replacement medication. Learn more about the basics of radiation therapy.
Neutron and proton radiation therapy
Neutron therapy is a different form of radiation therapy that uses neutrons rather than x-rays. Compared with conventional radiation therapy, neutrons can deliver 20 times to 100 times more energy along their path length, causing much greater damage to the cancer cells. Neutron radiation therapy has been tested on many different types of tumors, and its treatment for salivary gland tumors and AdCC has shown the greatest benefit.
In certain instances, neutron radiation therapy may be the first treatment for AdCC, particularly in areas of the body where it is difficult to perform surgery. However, neutron therapy carries more severe side effects than traditional radiation therapy, such as severe sore mouth and/or throat and difficulty swallowing; therefore, it is generally used more often with people with an inoperable tumor (surgery cannot be performed) or if the tumor recurs.
Medication to help increase saliva production and protect tissues may be given during this treatment. Neutrons cannot be used to treat large areas of the body for metastatic disease, but they can be used to treat isolated metastases that are causing problems, such as pain, blockage of part of the lung, or pressure on the spinal cord.
Proton therapy, also called proton beam therapy, is a type of external-beam radiation therapy that uses protons rather than x-rays. At high energy, protons can destroy cancer cells. The advantage of proton therapy is the ability to better control where the radiation is delivered, greatly reducing the damage to normal healthy tissues that surround the tumor. However, proton therapy has not been extensively researched for use in AdCC. Learn more about the basics of proton therapy.
Neutron and proton therapy are not widely available. Talk with your doctor for information about the availability of these treatments.
Chemotherapy is the use of drugs to destroy cancer cells, usually by ending the cancer cells’ ability to grow and divide. Chemotherapy is given by a medical oncologist, a doctor who specializes in treating cancer with medication.
Systemic chemotherapy gets into the bloodstream to reach cancer cells throughout the body. Common ways to give chemotherapy include an intravenous (IV) tube placed into a vein using a needle or in a pill or capsule that is swallowed.
A chemotherapy regimen, or schedule, usually consists of a specific number of cycles given over a set period. A patient may receive 1 drug at a time or combinations of different drugs given at the same time.
Chemotherapy is generally not used for AdCC, as this type of cancer appears to be less responsive to chemotherapy than other types of cancer. Various combinations of chemotherapy have been tried without much success. The combination of chemotherapy and radiation therapy is considered experimental for AdCC.
Because AdCC is a rare disease and, in general, the current chemotherapy is of limited benefit, it is recommended that people with AdCC ask about clinical trials to treat this disease. It may also be beneficial to get a second opinion regarding treatment options. Learn more about seeking a second opinion.
Learn more about the basics of chemotherapy and preparing for treatment. 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. Learn more about your prescriptions by using searchable drug databases.
Getting care for symptoms and side effects
AdCC and its treatment often cause side effects. In addition to treatments intended to slow, stop, or eliminate the cancer, an important part of cancer care is relieving a person’s symptoms and side effects. This approach is called palliative or supportive care, and it includes supporting the patient with his or her physical, emotional, and social needs.
Palliative care is any treatment that focuses on reducing symptoms, improving quality of life, and supporting patients and their families. Any person, regardless of age or type and stage of cancer, may receive palliative care. It works best when palliative care is started as early as needed in the cancer treatment process. People often receive treatment for the cancer and at the same time that they receive treatment to ease side effects. In fact, patients who receive both at the same time often have less severe symptoms, better quality of life, and report they are more satisfied with treatment.
Palliative treatments vary widely and often include medication, nutritional changes, relaxation techniques, emotional support, and other therapies. You may also receive palliative treatments similar to those meant to eliminate the cancer, such as chemotherapy, surgery, or radiation therapy. Talk with your doctor about the goals of each treatment in the treatment plan.
Before treatment begins, talk with your health care team about the possible side effects of your specific treatment plan and palliative care options. During and after treatment, be sure to tell your doctor or another health care team member if you are experiencing a problem so it can be addressed as quickly as possible. Learn more about palliative care.
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. Also, clinical trials might 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 and radiation therapy. Palliative care will also be important to help relieve symptoms and side effects.
For most patients, a diagnosis of metastatic cancer is very stressful and, at times, difficult to bear. Patients and their families are encouraged to talk about the way they are feeling with doctors, nurses, social workers, or other members of the health care team. It may also be helpful to talk with other patients, including through a support group.
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 does return after the original treatment, it is called recurrent cancer. It may come back in the same place, meaning it is a local recurrence, or nearby, which is a regional recurrence. If it comes back in another place, it is a distant recurrence.
When this occurs, a new cycle of testing will begin again to learn as much as possible about the recurrence. After this testing is done, you and your doctor will talk about your treatment options. Often the treatment plan will include the treatments described above, such as surgery 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 this type of recurrent cancer. Whichever treatment plan you choose, palliative care will be important for relieving symptoms and side effects.
People with recurrent cancer often experience emotions such as disbelief or fear. Patients are encouraged to talk with their health care team about these feelings and ask about support services to help them cope. Learn more about dealing with cancer recurrence.
If treatment doesn’t 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 many 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 is there to help, and many team members have special skills, experience, and knowledge to support patients and their families. Making sure a person is physically comfortable and free from pain is extremely important.
Patients who have advanced cancer and who are expected to live less than 6 months may want to consider a type of palliative care called 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.
