Abstract

OBJECT:

The authors present a retrospective analysis of 248 immunocompetent patients with primary intracerebral lymphoma treated at 19 French and Belgian medical centers between January 1980 and December 1995.

METHODS:

This study involved 127 female and 121 male patients with a median age of 61 years (range 2-88 years). All tumors available for review were classic diffuse non-Hodgkin's lymphoma, for which the phenotype was determined in 220 patients: 212 (96.4%) were B-cell and eight (3.6%) were T-cell type tumors. According to the Revised European-American classification of lymphoid neoplasms, most lesions were diffuse large cell tumors (62%). A total of 196 tumors were reviewed in 127 patients for whom preoperative computerized tomography and magnetic resonance studies were available. There was a single lesion in 66% of the cases, with a supratentorial location in 87%. Tumor location in the basal ganglia, corpus callosum, or fornix, infiltration of the periventricular ependyma, or a mirror pattern, were strongly suggestive of a lesion of lymphomatous origin. The histological diagnosis was obtained after surgical resection in 116 patients, with the remainder undergoing biopsy sampling only. Of the 248 patients studied, 129 (52%) received chemotherapy plus radiation therapy, 60 (24%) received radiation therapy alone, 35 (14%) received chemotherapy alone, and 24 (10%) received no postsurgical treatment.

CONCLUSIONS:

Using univariate analysis, the authors determined prognostic factors that were significantly associated with a favorable impact on survival including age younger than 60 years, radiation therapy (without evidence of a dose-response relationship), radiation therapy combined with chemotherapy, and chemotherapy consisting of anthracycline. Partial surgical resection was an unfavorable prognostic factor. Multivariate analysis was used to confirm the independent prognostic value of radiation therapy, age, chemotherapy consisting of anthracyclines or methotrexate, and partial surgical resection. This European survey provides a reasonable basis for the treatment of primary intracerebral lymphoma with the following sequence: stereotactic biopsy sampling, chemotherapy with a methotrexate- and anthracycline-based regimen, followed by cranial irradiation.
