Radiation Therapy for Lymphoma and Leukemia
Radiation therapy is the use of high-dose X-rays to treat cancer cells that may remain after surgery, especially if all of the cancer cannot be removed. Radiation therapy is often used for the treatment of cancer, such as non-Hodgkin's lymphoma (NHL), Hodgkin's lymphoma, and all types of leukemia. Radiation therapy may be used alone or in combination with other treatment options, such as chemotherapy.
For lymphoma or leukemia, radiation therapy may be given from a machine outside the body that directs radiation to the cancer (external radiation). Or it may be given inside the body (internal radiation), with radiation that is sealed inside of needles, seeds, wires, or catheters. The way radiation is given depends on the type and stage of cancer being treated.
What To Expect After Treatment
Side effects are common but generally go away when treatment is finished. They include:
Why It Is Done
When used during early-stage or nonaggressive NHL, radiation therapy is used to treat cells that may remain after surgery, especially if all of the cancer cannot be removed. Radiation may be used alone or in combination with other treatment options, such as chemotherapy. Radiation is also used for palliative care if chemotherapy is not working.
Radiation therapy is used to help keep an acute leukemia from spreading to the central nervous system (CNS prophylaxis). It is also used to treat recurrent leukemia that has spread to the brain or spinal cord.
How Well It Works
For some stages of leukemia and non-Hodgkin's lymphoma (NHL), radiation therapy works well when used alone. But it may be used in combination with chemotherapy, depending on the type and the stage of the cancer.
The short-term side effects of radiation therapy are common but usually get better and go away when treatments stop. These side effects depend on the area of the body affected by treatments and may include:
The long-term side effects of radiation therapy depend on what part of your body was treated, how much radiation you were given, and how long your treatment lasted. For example, radiation therapy to the pelvis may cause permanent sterility. Other long-term side effects may include brain changes, joint problems, lymphedema, mouth problems, and other cancers. These side effects depend on whether you also had chemotherapy.
What To Think About
Radiation therapy to the pelvis may cause permanent sterility. Discuss fertility options with your doctor before you begin pelvic radiation for NHL or CLL.
Unlike general radiation therapy, targeted radiation therapy uses monoclonal antibodies, which deliver radiation directly to the lymphoma cells.
