Primary lymphoma of the central nervous system. A report of 20 cases and a review of the literature.
Twenty patients with primary non-Hodgkin's lymphoma of the central nervous system (CNS) were seen at Vanderbilt and its affiliated hospitals between 1974 and 1986. Histologically, the most common subtypes were large, noncleaved cell lymphoma and immunoblastic lymphoma of B cells. However, multiple histologies were identified. Lesions most commonly involved the frontal lobes and/or deep nuclei. Positive cerebrospinal fluid cytology was rare at initial presentation. Seventeen patients were treated with surgical biopsy or resection followed by whole brain radiotherapy at a median dose of 5,000 cGy (range: 3,000-5,600 cGy). Seven patients have been followed for less than 12 months since diagnosis. Of the remaining patients, 7 (54%) survived at least 1 year. The extent of surgery performed, dose of radiotherapy administered, subclass of lymphoma diagnosed, or location(s) of involvement within the CNS did not influence survival. Treatment rarely caused a dramatic improvement in performance status despite objective signs of response. New treatment strategies are needed to improve the management of these tumors.
