Stereotactic radiation therapy uses a rigid head frame attached to the skull to aim radiation directly to a tumor, causing less damage to nearby healthy tissue. The total dose of radiation is divided into several smaller doses given over several days. This procedure is also called stereotactic external-beam radiation therapy and stereotaxic radiation therapy.
Chemotherapy is a cancer treatment that uses drugs to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. When chemotherapy is taken by mouth or injected into a vein or muscle, the drugs enter the bloodstream and can reach cancer cells throughout the body (systemic chemotherapy). When chemotherapy is placed directly into the cerebrospinal fluid, an organ, or a body cavity such as the abdomen, the drugs mainly affect cancer cells in those areas (regional chemotherapy). The way the chemotherapy is given depends on the type and stage of the cancer being treated.
Chemotherapy may be given after radiation therapy to kill any cancer cells that are left. Treatment given after radiation therapy, to lower the risk that the cancer will come back, is called adjuvant therapy.
See Drugs Approved for Head and Neck Cancer for more information. (Nasopharyngeal cancer is a type of head and neck cancer.)
Surgery is a procedure to find out whether cancer is present, to remove cancer from the body, or to repair a body part. Also called an operation. Surgery is sometimes used for nasopharyngeal cancer that does not respond to radiation therapy. If cancer has spread to the lymph nodes, the doctor may remove lymph nodes and other tissues in the neck.
New types of treatment are being tested in clinical trials.
Information about clinical trials is available from the NCI Web site.
Patients may want to think about taking part in a clinical trial.
For some patients, taking part in a clinical trial may be the best treatment choice. Clinical trials are part of the cancer research process. Clinical trials are done to find out if new cancer treatments are safe and effective or better than the standard treatment.
