Abstract
Aims: Primary non-Hodgkin lymphoma of bone account for 5% of extra nodal lymphomas. The Authors report their experience referring to the results obtained with a multidisciplinary approach.
Materials: 18 cases of lymphoma of bone were included. Medium age was 63 yrs. All cases have been classified according to the REAL classification system. Patients have been staged with: total body CT scan, bone marrow aspirate, bone marrow biopsy, LDH serum level, skeletal survey and MRI of the skeletal segments involved. We treated 10 cases with solitary localization and 8 with multiple ones. Three patients presented with a pathologic fracture at diagnosis.
Chemotherapy protocols were:
MACOP-B < 60 yrs.
VNCOP-B > 60 yrs.
Seven patients received the PROMACE-CYTABOM protocol.
13 patients received EBRT (40 Gy). Ten patients received a surgical treatment: internal fixation in 7 cases and of spine stabilization in 3 cases
Results: At a medium follow-up of 40 months overall survival was 34,6 months and 14,5 months respectively for solitary or multiple localizations. Surgical treatment has been useful in improving performance status and in some cases to obtain a better control of the disease.
Discussion: In our experience bone lymphomas have always a high grade histology. Chemotherapy constitutes the treatment of choice. Surgical treatment have to be considered as a support treatment. Prognosis is worse in multiple localizations
