Primary CNS Lymphoma Treatment (PDQ®): Treatment - Patient Information [NCI] - Treatment Option Overview


A network of blood vessels and tissue, called the blood-brain barrier, protects the brain from harmful substances. This barrier can also keep anticancer drugs from reaching the brain. In order to treat CNS lymphoma, certain drugs may be used to make openings between cells in the blood-brain barrier. This is called blood-brain barrier disruption. Anticancer drugs infused into the bloodstream may then reach the brain.

Steroid therapy

Steroids are hormones made naturally in the body. They can also be made in a laboratory and used as drugs. Glucocorticoids are steroid drugs that have an anticancer effect in lymphomas.

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.

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.
