This section outlines treatments that are the standard of care (the best proven treatments available) for this specific type of tumor. When making treatment plan decisions, patients are also encouraged to consider clinical trials as an option. A clinical trial is a research study to test a new treatment to evaluate whether it is safe, effective, and possibly better than standard treatment. Your doctors can help you review all treatment options. For more information, see the Clinical Trials  and Current 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 .
The most common treatment options for parathyroid cancer are surgery, radiation therapy, and treatment of hypercalcemia . Chemotherapy may also be recommended. Treatment will include efforts to both eliminate the tumor and control the amount of calcium in the patient’s bloodstream.
Descriptions of these common treatment options are listed below. Treatment options and recommendations depend on several factors, including the type and stage of the tumor, possible side effects, and the patient’s preferences and overall health. Learn more about making treatment decisions .
There are a number of medications used to reduce calcium levels in the blood, including calcitonin (Calcimar, Cibacalcin, Miacalcin), plicamycin (Mithramycin), gallium nitrate (Ganite), bisphosphonates (Aredia, Bonefos, Loron), or zoledronic acid (Zometa). Most of these drugs are only used for short periods of time until treatment to remove the tumor can be started.
Surgery is the removal of the tumor and surrounding tissue during an operation.
Surgery is the primary treatment for a parathyroid tumor, regardless of whether the tumor is benign or cancerous. A surgical oncologist is a doctor who specializes in treating a tumor using surgery.
It is difficult to determine before surgery if a parathyroid tumor is benign or malignant. Therefore, the surgeon needs to remove the entire gland and any tissue that looks abnormal. In addition, because parathyroid tissue is very likely to implant in the surgical bed (area where tissue was removed during surgery), it is important for the surgeon to remove the tumor, any abnormal tissue, and a clean margin (tissue around the tumor that is disease-free). The doctor may also recommend radiation therapy (see below) after surgery to the affected area of the neck.
Surgery for a benign parathyroid tumor is called a parathyroidectomy. Talk with your surgeon about the role of minimally invasive surgery for a single gland tumor that is strongly believed to be benign.
Surgery for parathyroid cancer is more extensive and includes the complete removal of the parathyroid gland as well as surrounding tissues such as the nearby thyroid gland, adjoining fatty tissues, lymph nodes, and if possible, the surrounding muscles.
If a surgeon finds the tumor is benign during surgery, it is common to check the patient’s level of parathyroid hormone in the blood during the operation. If necessary, the surgeon will then re-implant one of the normal parathyroid glands that had been removed earlier in the operation. However, if the tumor is cancerous, re-implantation should not be done to avoid putting cancer cells back into the body. Learn more about cancer surgery .
Radiation therapy is the use of high-energy x-rays or other particles to kill cancer cells. A doctor who specializes in giving radiation therapy to treat cancer is called a radiation oncologist. A radiation therapy regimen (schedule) usually consists of a specific number of treatments given over a set period of time.
Occasionally, radiation therapy may be recommended after surgery for parathyroid cancer. Radiation therapy may help reduce the risks of parathyroid cancer recurring in the neck, but it is difficult to evaluate whether this treatment is beneficial because this type of cancer is so rare.
Side effects from radiation therapy may include fatigue, mild skin reactions, upset stomach, and loose bowel movements. Most side effects go away soon after treatment is finished. Learn more about radiation therapy .
Chemotherapy is the use of drugs to kill cancer cells, usually by stopping the cancer cells’ ability to grow and divide. Systemic chemotherapy is delivered through the bloodstream to reach cancer cells throughout the body. Chemotherapy is given by a medical oncologist, a doctor who specializes in treating cancer with medication. A chemotherapy regimen (schedule) usually consists of a specific number of cycles given over a set period of time. A patient may receive one drug at a time or combinations of different drugs at the same time.
The side effects of chemotherapy depend on the individual and the dose used, but they can include fatigue, risk of infection, nausea and vomiting, loss of appetite, and diarrhea. These side effects usually go away once treatment is finished.
Chemotherapy is rarely effective at treating metastatic or recurrent parathyroid cancers. More clinical trials are needed.
Learn more about chemotherapy  and preparing for treatment . The medications used to treat tumors 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 .
Cancer and its treatment often cause side effects. In addition to treatment 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 can help a person at any stage of illness. People often receive treatment for the cancer and treatment to ease side effects at the same time. In fact, patients who receive both often have less severe symptoms, better quality of life, and report they are more satisfied with treatment.
Before treatment begins, talk with your health care team about the possible side effects of your specific treatment plan and supportive care options. And during and after treatment, be sure to tell your doctor or another health care team member if you are experiencing a problem, so it is addressed as quickly as possible. Learn more about palliative care .
Recurrent parathyroid tumor
A remission is when cancer cannot be detected in the body and there are no symptoms. This may also be called “no evidence of disease” or NED.
A remission can be temporary or permanent. This uncertainty leads to many survivors feeling worried or anxious that the tumor will come back. While many remissions are permanent, it’s important to talk with your doctor about the possibility of the tumor returning. Understanding the risk of recurrence and the treatment options may help you feel more prepared if it does return. Learn more about coping with the fear of recurrence .
If the tumor does return after the original treatment, it is called a recurrent tumor. It may come back in the same place (called a local recurrence), nearby (regional recurrence), or in another place (distant recurrence).
The first sign of recurrence after treatment may be high blood calcium levels. Therefore, tests to watch for a recurrence include blood tests for PTH and calcium level changes, as well as ultrasounds of the neck (see Diagnosis ).
If a recurrence is detected, the cycle of testing will begin again to learn as much as possible about the tumor. After testing is done, you and your doctor will talk about your treatment options. Often the treatment plan will include the therapies described above (such as surgery, chemotherapy, and radiation therapy) but may be used in a different combination or given at a different pace. Your doctor may also suggest clinical trials that are studying new ways to treat this type of recurrent tumor.
People with recurrent disease 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 recurrence .
Metastatic parathyroid cancer
If cancer has spread to another location in the body, it is called metastatic cancer. Patients with this diagnosis are encouraged to talk with doctors who are experienced in treating this stage of cancer, because there can be different opinions about the best treatment plan. Learn more about seeking a second opinion  before starting treatment, so you are comfortable with the treatment plan chosen. This discussion may include clinical trials .
Your health care team may recommend a treatment plan that includes a combination of surgery, chemotherapy, and radiation therapy. Supportive care will also be important to help relieve symptoms and side effects.
For many patients, a diagnosis of metastatic cancer can be 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.
If treatment fails
Recovery from cancer is not always possible. If treatment is not successful, the disease may be called advanced or terminal cancer.
This diagnosis is stressful, and this is difficult to discuss for many people. 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.
Palliative care given toward the end of a person’s life is called hospice care . You and your family are encouraged to think about where you would be most comfortable: at home, in the hospital, or in a hospice environment. Nursing care and special equipment can make staying at home a workable alternative for many families. Learn more about advanced cancer care planning .
After the death of a loved one, many people need support to help cope with the loss. Learn more about grief and bereavement .
