Primary bone lymphoma in 24 patients treated between 1955 and 1999.
The authors present their experience in the treatment of 24 patients with primary bone lymphoma. Eighty-one patients treated between 1955 and 1999 were evaluated, and 57 were excluded because of misdiagnosis. The male to female ratio was 7:5 and the median age was 38.5 years (range, 18-69 years). Two patients had human immunodeficiency virus. Seventeen patients had intermediate-grade lymphomas (Working Formulation), nine patients had centroblastic subtype (Kiel), and 22 patients had B immunophenotype. Nine patients had combined treatment with chemotherapy and radiation therapy, and nine patients had chemotherapy alone. The mean followup was 13.2 years (range, 1.5-37.3 years). Three patients had surgery, two because of subtrochanteric fractures (one patient had closed reduction and internal fixation and the other patient had resection and endoprosthesis reconstruction). The third patient presented with myelocompression at the thoracic level, and he had decompression surgery. Only one patient had radiation therapy and two patients had no treatment. There have been no local recurrences in 17 patients (70.8%). Seven patients (29.2%) died with evidence of disease within a followup of 11 months. The results of the current study showed that patients with primary bone lymphoma have a good prognosis when they are treated with chemotherapy, regardless of whether radiation therapy was given. Surgery usually is appropriate for patients with fractures.
