Recurrent Adult Non-Hodgkin Lymphoma
Recurrent adult non-Hodgkin lymphoma is cancer that has recurred (come back) after it has been treated. The lymphoma may come back in the lymph system or in other parts of the body. Indolent lymphoma may come back as aggressive lymphoma. Aggressive lymphoma may come back as indolent lymphoma.
Treatment Option Overview
There are different types of treatment for patients with non-Hodgkin lymphoma.
Different types of treatment are available for patients with non-Hodgkin lymphoma. Some treatments are standard (the currently used treatment), and some are being tested in clinical trials. A treatment clinical trial is a research study meant to help improve current treatments or obtain information on new treatments for patients with cancer. When clinical trials show that a new treatment is better than the standard treatment, the new treatment may become the standard treatment. Patients may want to think about taking part in a clinical trial. Some clinical trials are open only to patients who have not started treatment.
For pregnant women with non-Hodgkin lymphoma, treatment is carefully chosen to protect the fetus. Treatment decisions are based on the mother's wishes, the stage of the non-Hodgkin lymphoma, and the age of the fetus. The treatment plan may change as the symptoms, cancer, and pregnancy change. Choosing the most appropriate cancer treatment is a decision that ideally involves the patient, family, and health care team.
Six types of standard treatment are used:
Radiation therapy is a cancer treatment that uses high-energy x-rays or other types of radiation to kill cancer cells and keep them from growing. There are two types of radiation therapy. External radiation therapy uses a machine outside the body to send radiation toward the cancer. Internal radiation therapy uses a radioactive substance sealed in needles, seeds, wires, or catheters that are placed directly into or near the cancer. The way the radiation therapy is given depends on the type and stage of the cancer being treated.
For pregnant women with non-Hodgkin lymphoma, radiation therapy should be given after delivery, if possible, to avoid any risk to the fetus. If treatment is needed right away, pregnant women may decide to continue the pregnancy and receive radiation therapy. However, lead used to shield the fetus may not protect it from scattered radiation that could possibly cause cancer in the future.
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). To treat certain types of adult non-Hodgkin lymphoma that spread to the brain, CNS prophylaxis (chemotherapy given to kill cancer cells in the brain or spinal cord) may be used. The way the chemotherapy is given depends on the type and stage of the cancer being treated.
Combination chemotherapy is treatment using two or more anticancer drugs. Steroid drugs may be added, to relieve swelling and inflammation.
In pregnant women, the fetus is exposed to chemotherapy when the mother is treated, and some anticancer drugs cause birth defects. Because anticancer drugs are passed to the fetus through the mother, both must be watched closely when chemotherapy is given.

Targeted therapy is a type of treatment that uses drugs or other substances to identify and attack specific cancer cells without harming normal cells. Monoclonal antibody therapy and proteasome inhibitor therapy are two types of targeted therapy used to treat adult non-Hodgkin lymphoma.
Monoclonal antibody therapy is a cancer treatment that uses antibodies made in the laboratory from a single type of immune system cell. These antibodies can identify substances on cancer cells or normal substances that may help cancer cells grow. The antibodies attach to the substances and kill the cancer cells, block their growth, or keep them from spreading. Monoclonal antibodies are given by infusion. They may be used alone or to carry drugs, toxins, or radioactive material directly to cancer cells. Monoclonal antibodies that have been joined to radioactive material are called radiolabeled monoclonal antibodies.
Proteasome inhibitor therapy blocks the action of proteasomes in cancer cells and may prevent the growth of tumors.
See Drugs Approved for Non-Hodgkin Lymphoma for more information.
If the blood becomes thick with extra antibody proteins and affects circulation, plasmapheresis is done to remove extra plasma and antibody proteins from the blood. In this procedure, blood is removed from the patient and sent through a machine that separates the plasma (the liquid part of the blood) from the blood cells. The patient's plasma contains the unneeded antibodies and is not returned to the patient. The normal blood cells are returned to the bloodstream along with donated plasma or a plasma replacement. Plasmapheresis does not keep new antibodies from forming.
Biologic therapy is a treatment that uses the patient's immune system to fight cancer. Substances made by the body or made in a laboratory are used to boost, direct, or restore the body's natural defenses against cancer. This type of cancer treatment is also called biotherapy or immunotherapy.
Interferon is a type of biologic therapy. It affects the division of cancer cells and can slow tumor growth.
Watchful waiting is closely monitoring a patient's condition without giving any treatment until symptoms appear or change.
New types of treatment are being tested in clinical trials.
This summary section describes treatments that are being studied in clinical trials. It may not mention every new treatment being studied. Information about clinical trials is available from the NCI Web site.
Vaccine therapy is a type of biologic therapy. Biologic therapy is a treatment that uses the patient's immune system to fight cancer. Substances made by the body or made in a laboratory are used to boost, direct, or restore the body's natural defenses against cancer. This type of cancer treatment is also called biotherapy or immunotherapy. Vaccine therapy can also be a type of targeted therapy.
High-dose chemotherapy with stem cell transplant
High-dose chemotherapy with stem cell transplant is a method of giving high doses of chemotherapy and replacing blood -forming cells destroyed by the cancer treatment. Stem cells (immature blood cells) are removed from the blood or bone marrow of the patient or a donor and are frozen and stored. After the chemotherapy is completed, the stored stem cells are thawed and given back to the patient through an infusion. These reinfused stem cells grow into (and restore) the body's blood cells.
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.
Many of today's standard treatments for cancer are based on earlier clinical trials. Patients who take part in a clinical trial may receive the standard treatment or be among the first to receive a new treatment.
Patients who take part in clinical trials also help improve the way cancer will be treated in the future. Even when clinical trials do not lead to effective new treatments, they often answer important questions and help move research forward.
Patients can enter clinical trials before, during, or after starting their cancer treatment.
Some clinical trials only include patients who have not yet received treatment. Other trials test treatments for patients whose cancer has not gotten better. There are also clinical trials that test new ways to stop cancer from recurring (coming back) or reduce the side effects of cancer treatment.
Clinical trials are taking place in many parts of the country. See the Treatment Options section that follows for links to current treatment clinical trials. These have been retrieved from NCI's listing of clinical trials.
Follow-up tests may be needed.
Some of the tests that were done to diagnose the cancer or to find out the stage of the cancer may be repeated. Some tests will be repeated in order to see how well the treatment is working. Decisions about whether to continue, change, or stop treatment may be based on the results of these tests. This is sometimes called re-staging.
Some of the tests will continue to be done from time to time after treatment has ended. The results of these tests can show if your condition has changed or if the cancer has recurred (come back). These tests are sometimes called follow-up tests or check-ups.
