[Spinal cord compression in non-Hodgkin's lymphoma. A study of 10 patients]

Spinal cord compression is an infrequent event in patients with non-Hodgkin's lymphomas (NHL) and early diagnosis and therapy are required. The main clinical and histologic characteristics as well as the response to therapy in 10 NHL patients with spinal cord compression diagnosed at a single center in a 7-year period are referred. The main initial clinical manifestations were pain in dorsal or lumbar regions (5 cases) and paraparesia or paraplegia (5 patients). Infection by human immunodeficiency virus (HIV) was present in four cases. In 8 patients spinal cord compression was the initial manifestation of NHL. Pathologic diagnosis showed intermediate or high-grade lymphoma in 8 out of 10 cases and immunologic phenotype was B-cell in all cases. Laminectomy followed by radiation therapy and chemotherapy was performed in 4 cases, radiotherapy and chemotherapy in two, isolated chemotherapy in 3 and radiation therapy was administered to the remaining case. Complete response was observed in 4 cases and 6 cases were resistant to treatment. No patient with HIV infection responded to treatment. Six patients had died, median survival time for the whole series being 4 months, and the actuarial probability of survival was 40% at the first year.
