If you have indolent non-Hodgkin lymphoma without symptoms, you may not need treatment for the cancer right away. The doctor watches your health closely so that treatment can start when you begin to have symptoms. Not getting cancer treatment right away is called watchful waiting.
If you have indolent lymphoma with symptoms, you will probably receive chemotherapy and biological therapy. Radiation therapy may be used for people with Stage I or Stage II lymphoma.
If you have aggressive lymphoma, the treatment is usually chemotherapy and biological therapy. Radiation therapy also may be used.
People who choose watchful waiting put off having cancer treatment until they have symptoms. Doctors sometimes suggest watchful waiting for people with indolent lymphoma. People with indolent lymphoma may not have problems that require cancer treatment for a long time. Sometimes the tumor may even shrink for a while without therapy. By putting off treatment, they can avoid the side effects of chemotherapy or radiation therapy.
If you and your doctor agree that watchful waiting is a good idea, the doctor will check you regularly (every 3 months). You will receive treatment if symptoms occur or get worse.
Chemotherapy for lymphoma uses drugs to kill lymphoma cells. It is called systemic therapy because the drugs travel through the bloodstream. The drugs can reach lymphoma cells in almost all parts of the body.
You may receive chemotherapy by mouth, through a vein, or in the space around the spinal cord. Treatment is usually in an outpatient part of the hospital, at the doctor's office, or at home. Some people need to stay in the hospital during treatment.
Chemotherapy is given in cycles. You have a treatment period followed by a rest period. The length of the rest period and the number of treatment cycles depend on the stage of your disease and on the anticancer drugs used.
People with certain types of non-Hodgkin lymphoma may have biological therapy. This type of treatment helps the immune system fight cancer.
Monoclonal antibodies are the type of biological therapy used for lymphoma. They are proteins made in the lab that can bind to cancer cells. They help the immune system kill lymphoma cells. People receive this treatment through a vein at the doctor's office, clinic, or hospital.
Radiation therapy (also called radiotherapy) uses high-energy rays to kill lymphoma cells. It can shrink tumors and help control pain. Two types of radiation therapy are used for people with lymphoma:
- external radiation. A large machine aims the rays at the part of the body where lymphoma cells have collected. This is local therapy because it affects cells in the treated area only. Most people go to a hospital or clinic for treatment 5 days a week for several weeks.
- systemic radiation. Some people with lymphoma receive an injection of radioactive material that travels throughout the body. The radioactive material is bound to monoclonal antibodies that seek out lymphoma cells. The radiation destroys the lymphoma cells.
Stem Cell Transplantation
If lymphoma returns after treatment, you may receive stem cell transplantation. A transplant of your own blood-forming stem cells allows you to receive high doses of chemotherapy, radiation therapy, or both. The high doses destroy both lymphoma cells and healthy blood cells in the bone marrow.
Stem cell transplants take place in the hospital. After you receive high-dose treatment, healthy blood-forming stem cells are given to you through a flexible tube placed in a large vein in your neck or chest area. New blood cells develop from the transplanted stem cells.
The stem cells may come from your own body or from a donor.
