Twenty-five years ago, a PCNSL was a rarity; today they are more common. Why? The increase is due to three groups: a) patients with compromised immune systems who are now living longer (e.g., cancer and AIDS patients), b) patients with lupus, rheumatoid arthritis, and bone marrow transplantation who are receiving immune suppressive therapies; and c) patients who are having (more frequent) biopsies. The latter has led to diagnoses that are more accurate. Does the location of the CNS lymphoma make a difference?

CNS lymphomas originating in the brain are still unusual. It’s imperative that a search begin in all lymph node areas (neck, groin, chest, abdomen), since lymphomas usually start there. Diagnosis What are symptoms of a CNS lymphoma in the brain?

Symptoms include headache, vomiting, forgetfulness, difficulty finding words, confusion, double vision, wobbliness (ataxia), weakness of a leg or arm, and sometimes facial weakness. What tests are needed for the initial evaluation of a CNS lymphoma?

Remember: CNS Lymphomas in the brain are uncommon. They require complex management with chemotherapy first, followed by radiation and possibly immune therapy (see below). Evaluation should take place in a comprehensive cancer center where physicians with different areas of expertise can work together. This team might include neurooncologists, neuroradiologists, neurosurgeons, neuropathologists, hematopathologists, neurologists, oncologists, radiation oncologists, endocrinologists, and neuropsychologists. Due to its rarity, families should be encouraged to participate in clinical trials in an attempt to improve and optimize therapy. Clinical Trials

The role of neurosurgery for lymphomas is different from other tumors in the brain. For most brain tumors, the more tumor tissue that can be removed (for diagnosis and treatment) by the surgeon, the better the prognosis for longer life. Lymphomas are the exception.

Yes! We know that even the best surgeon cannot completely remove all cancer cells; this is even truer for lymphomas. Thus, the after-surgical therapies are critical to your treatment and longer life. I recommend a Tumor Board evaluation or referral to a medical center that specializes in CNS lymphoma treatment. What is a shunt operation, and why is it necessary?

If a tumor causes pressure within the skull to increase, a shunt may be surgically placed. A shunt is a thin piece of tubing that is inserted intone of the spaces of the brain (ventricles) or sometimes into the space around the spine that contains cerebrospinal fluid (subarachnoid space). The other end of the tubing is threaded under the skin from the head usually to the abdominal cavity. Excess cerebrospinal fluid is drained from the brain and is absorbed in the abdominal cavity. The shunt contains a one-way valve that opens when there is too much fluid in the brain. Shunts may be temporary (until the tumor is removed) or permanent. 4 Radiation Therapy How has the role of radiation therapy changed in the treatment of CNS lymphoma of the brain?

Twenty years ago, all patients with lymphomas of the brain or spine received immediate radiotherapy and showed dramatic tumor shrinkage within days. The problem was that the tumor returned in weeks tmonths. 1, 2 Then, sensitivity of PCNSLs to chemotherapy was not understood.

Primary central nervous system lymphomas illustrate of how poorly planned therapy can affect survival. There is a reason for the specific sequence of therapies. Radiation to the human brain causes changes in brain cells and blood vessels, which render them exquisitely sensitive to the toxic effects of methotrexate, the best chemotherapy we have for lymphoma. What is the role of chemotherapy and other drugs for lymphomas?

Chemotherapy has evolved into the major component of successful treatment, paralleling the success of lymphoma therapy in other locations of the body. Fortunately, most lymphomas interrupt the blood-brain-barrier, so drug delivery to the tumor in the brain is not the problem. Several adult and pediatric clinical trials of new chemotherapies and immunotherapies are underway.

Immunotherapy uses the immune system to recognize, target, and kill tumor cells. Human lymph cells are the best studied and characterized in the body. Scientists know that one protein called CD-20 is on the surface of B-lymphoma cells and not on other normal tissues.
