ON THIS PAGE: You will learn about the different ways doctors use to treat people with this type of cancer. To see other pages, use the menu on the side of your screen.
This section outlines treatments that are the standard of care (the best proven treatments available) for this specific type of cancer. 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 approach to treatment to evaluate whether it is safe, effective, and possibly better than the standard treatment. Clinical trials may test such approaches as a new drug, a new combination of standard treatments, or new doses of current therapies. Your doctor can help you review all treatment options. For more information, see the 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 .
Descriptions of the most common treatment options for thymoma 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. Your care plan may also include treatment for 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. Also, talk about the goals of each treatment with your doctor and what you can expect while receiving the treatment. Learn more about making treatment decisions .
Surgery is the removal of the tumor and surrounding tissue during an operation.
Surgery is the most common treatment for early-stage thymoma. For thymoma, surgery is usually done by a thoracic surgeon, a doctor who specializes in surgery of the chest. The most common type of surgery for thymoma is called a median sternotomy. During a median sternotomy, the breastbone is split, and the thymoma and the tissue surrounding the tumor are removed. Surgery is often the only treatment needed for early-stage thymoma.
Later-stage thymoma may include surgery to remove as much of the tumor as possible when the entire thymoma cannot be removed with surgery. This is called debulking surgery and may provide some relief of symptoms. If the thymoma has spread to the lining of the lung, surgery may also include the removal of the lung lining or a portion of the lung.
Talk with your surgeon beforehand about possible side effects, which are based on the extent of surgery, and what you can expect regarding your recovery from surgery. Learn more about cancer surgery .
Radiation therapy is the use of high-energy x-rays or other particles to destroy cancer cells. A doctor who specializes in giving radiation therapy to treat cancer is called a radiation oncologist. The most common type of radiation treatment is called external-beam radiation therapy, which is radiation given from a machine outside the body. A radiation therapy regimen (schedule) usually consists of a specific number of treatments given over a set period of time.
External-beam radiation therapy can be used alone, following surgery, or in combination with chemotherapy in the treatment of thymoma. For patients with later-stage disease, radiation therapy is often recommended after the thymoma has been surgically removed.
Side effects from radiation therapy may include fatigue, mild skin reactions, difficulty swallowing, upset stomach, and loose bowel movements. Most side effects go away soon after treatment is finished.

Chemotherapy is the use of drugs to destroy cancer cells, usually by stopping 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 is delivered through 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 (orally). 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. Common drugs for thymoma include:
- Carboplatin (Paraplatin)
- Cisplatin (Platinol)
- Cyclophosphamide (Neosar)
- Doxorubicin (Adriamycin)
- Etoposide (Toposar, VePesid)
- Ifosfamide (Ifex)
- Octreotide (Sandostatin)
- Paclitaxel (Taxol)
- Pemetrexed (Alimta)
The common drug combinations for thymoma include:
- Carboplatin and paclitaxel
- Cyclophosphamide, doxorubicin, and cisplatin
- Etoposide and cisplatin
These chemotherapy combinations are sometimes used to shrink the tumor before surgery if the thymoma is found at a later stage. Chemotherapy may also be used for people who have stage IVB/advanced thymoma or recurrent thymoma that cannot be completely removed with surgery. Recurrent thymoma is thymoma that has come back after treatment.
The side effects of chemotherapy depend on the individual, the type of drug, and the dose used, but they can include fatigue, risk of infection, nausea and vomiting, hair loss, loss of appetite, and diarrhea. These side effects usually go away once treatment is finished.
Learn more about 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
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.
Palliative treatments vary widely and often include medication, nutritional changes, relaxation techniques, and other therapies. You may also receive palliative treatments similar to those meant to eliminate the cancer, such as chemotherapy, surgery, and radiation therapy. Talk with your doctor about the goals of each treatment in your treatment plan.
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 .
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, radiation, and chemotherapy. Sometimes, when thymoma is metastatic and growing very slowly, your health care team may recommend no treatment for a period of time. However, when thymoma has spread to another location in the body, it is unlikely that any of the treatments will make the cancer go away forever. Supportive care is also 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 “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 cancer will come back. While many remissions are permanent, it’s important to talk with your doctor about the possibility of the cancer returning. Understanding the 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 (called a local recurrence), nearby (regional recurrence), or in another place (distant recurrence).
When this occurs, a cycle of testing will begin again to learn as much as possible about the recurrence, including whether the cancer’s stage has changed. 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 they 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 cancer.
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 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.
Patients who have advanced cancer and who are expected to live less than six 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 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 them cope with the loss. Learn more about grief and loss .
