SWOG-9310, INT-0143


I.  Assess the rate of tumor response to 
methotrexate/vincristine/procarbazine/dexamethasone administered prior to 
radiotherapy in patients with primary central nervous system lymphoma.

II.  Compare survival of these patients to historical controls treated with 
radiotherapy alone.

III.  Assess the long-term toxicity of this regimen.

IV.  Provide data for consideration of a randomized trial to compare 
chemotherapy alone vs. chemotherapy plus radiotherapy in an effort to reduce 
the morbidity of cranial irradiation.

Note: The purpose of most clinical trials listed in this database is to test new cancer treatments, or new methods of diagnosing, screening, or preventing cancer. Because all potentially harmful side effects are not known before a trial is conducted, dose and schedule modifications may be required for participants if they develop side effects from the treatment or test. The therapy or test described in this clinical trial is intended for use by clinical oncologists in carefully structured settings, and may not prove to be more effective than standard treatment. A responsible investigator associated with this clinical trial should be consulted before using this protocol.
