Non-Hodgkin's lymphoma presenting with spinal involvement: the Sheffield Lymphoma Group experience (1970-2000)

Spinal non-Hodgkin's lymphoma is rare. We retrospectively reviewed the clinical and histopathologic records of 39 consecutive patients referred to the Sheffield Lymphoma Group from 1970 to 2000 and analysed the prognostic differences between localised (stage IE and IIE) and secondary (stage III and IV) spinal non-Hodgkin's lymphoma (S-NHL) patients. Forty-five percent of all patients were over 60 years old. More patients were male (58%); presented with stage IE and IIE (63%), mostly of intermediate/high grade histology (74%); over a third had symptoms; nearly a third (11 patients) were paraplegic and 14 had sphincter dysfunction at diagnosis. The overall survival of all patients was 39% at 5 years (median 24.7 months), whilst that of localised S-NHL was 51% (median 89.7 months). Univariate analysis showed better survival for patients with good mobility status at presentation (p < 0.0l) and complete response to initial treatment (p < 0.00l). In primary S-NHL, histology (p < 0.05) significantly influenced overall survival. In conclusion, disease is frequently locally advanced at presentation with aggressive histologic grade: thorough staging should always be performed to exclude widespread disease. Good mobility status predicts for good survival outcome. Optimal treatment is still uncertain.
