Abstract

Purpose To assess the clinical profile, treatment outcome, and prognostic factors in primary spinal epidural lymphoma (PSEL). Methods and Materials Between 1982 and 2002, 52 consecutive patients with PSEL were treated in nine institutions of the Rare Cancer Network. Forty-eight patients had an Ann Arbor stage IE and four had a stage IIE. Forty-eight patients underwent decompressive laminectomy, all received radiotherapy (RT) with (n = 32) or without chemotherapy (n = 20). Median RT dose was 36 Gy (range, 6-50 Gy). Results Six (11%) patients progressed locally and 22 (42%) had a systemic relapse. At last follow-up, 28 patients were alive and 24 had died. The 5-year overall survival, disease-free survival, and local control were 69%, 57%, and 88%, respectively. In univariate analyses, favorable prognostic factors were younger age and complete neurologic response. Multivariate analysis showed that combined modality treatment, RT volume, total dose more than 36 Gy, tumor resection, and complete neurologic response were favorable prognostic factors. Conclusions Primary spinal epidural lymphoma has distinct clinical features and outcome, with a relatively good prognosis. After therapy, local control is excellent and systemic relapse occurs in less than half the cases. Combined modality treatment appears to be superior to RT alone.
