Primary bone lymphoma or non-Hodgkin lymphoma of bone is a rare disease. There are only a few
case series of stage IE of this condition in medical literature. The aim of this study is to determine the rate of survival
for stage IE after combined modality treatment, the rate of local recurrence, and the results of limb salvage in cases
of local recurrence.
We collected data from 61 patients with histologically confirmed PBL treated at the Musculoskeletal
Oncology Department of our hospital from 2000 to 2010. Retrospective evaluation included demographics, symptoms,
tumor locations, outcomes of surgical treatment for local recurrence and survival rates.
All patients received Combined Modality Therapy. Overall,five year survival was 89% and five year disease
free survival rate was 78%. Local recurrence occurred in 6 patients during follow up period, which was treated surgically
by wide excision and reconstruction. The mean follow-up for the local recurrence group was 36(24-54) months and
mortality rate in this group was 17%.
Combined Modality Therapy for stage IE primary bone lymphomaresults in good survival rate. In case
of local recurrence, wide excision and reconstruction improves the outcomes.
