Spinal cord compression as a primary manifestation of aggressive malignant lymphomas: long-term analysis of treatments with radiotherapy, chemotherapy or combined therapy.
A controlled clinical trial evaluated the usefulness of three different therapeutic approaches in the treatment of spinal cord compression (SCC) as primary manifestation of malignant lymphoma with the following end-points: neurological function, event free survival (EFS) and overall survival (OS). Forty-eight patients with SCC as unique manifestation (IE) of malignant lymphoma, were randomly assigned to receive either: radiotherapy (16 patients), chemotherapy (11 patients) or combined therapy (radiotherapy followed by chemotherapy, 21 patients). Although neurological recovery was similar in both groups, EFS and OS were better in the combined therapy arm. Actuarial curves at 10 years showed that EFS was 50% for patients treated with radiotherapy, 46% in the chemotherapy arm and 76% in the combined therapy group. Overall survival was 58, 38 and 76%, respectively, however because of the small number of patients, no statistical differences were observed. Although malignant lymphoma with SCC as primary manifestation could be considered as a localized disease, more patients could have microscopic disseminated disease. The use of combined therapy improves the outcome in this group of patients, and so it should be considered the treatment of choice.
