Purpose Primary bone lymphoma is a rare disease. Little is reported about surgical procedures in these patients. We evaluated a single-centre consecutive series of 21 patients for results, prognostic factors and surgical treatment. Methods Patient ages ranged from 19 to 82 years. The most frequently affected site was the spine (six cases), followed by the ileum, femur and mandible (three cases each). Four patients were treated with chemotherapy and 17 with chemotherapy and radiation therapy. Six patients were affected by a pathological fracture. Surgery was performed in four patients (19 %), in two cases before chemotherapy, in one case during chemotherapy and in one case after chemotherapy and radiotherapy. Five patients died within the range of three to 36 months after diagnosis. Average follow-up of the remaining patients was 62.8 (19-145) months. Results Overall survival was 74.2 % at five years. The only positive prognostic factor was complete remission after chemotherapy. A trend for better survival was present for International Prognostic Index (IPI) score (P = 0.051), under 40 years of age (P = 0.10) and abnormal lactate dehydrogenase (LDH) values (P = 0.10), but it did not reach statistical significance. Conclusions Surgical treatment should be aimed at restoring function and eliminating pain while minimising delays in the chemotherapy schedule. When feasible, postponing surgery until after chemotherapy is advisable.

Abstract
Purpose Primary bone lymphoma is a rare disease. Little is reported about surgical procedures in these patients. We evaluated a single-centre consecutive series of 21 patients for results, prognostic factors and surgical treatment. Methods Patient ages ranged from 19 to 82 years. The most frequently affected site was the spine (six cases), followed by the ileum, femur and mandible (three cases each). Four patients were treated with chemotherapy and 17 with chemotherapy and radiation therapy. Six patients were affected by a pathological fracture. Surgery was performed in four patients (19 %), in two cases before chemotherapy, in one case during chemotherapy and in one case after chemotherapy and radiotherapy. Five patients died within the range of three to 36 months after diagnosis. Average follow-up of the remaining patients was 62.8 (19-145) months. Results Overall survival was 74.2 % at five years. The only positive prognostic factor was complete remission after chemotherapy. A trend for better survival was present for International Prognostic Index (IPI) score (P = 0.051), under 40 years of age (P = 0.10) and abnormal lactate dehydrogenase (LDH) values (P = 0.10), but it did not reach statistical significance. Conclusions Surgical treatment should be aimed at restoring function and eliminating pain while minimising delays in the chemotherapy schedule. When feasible, postponing surgery until after chemotherapy is advisable.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
