Primary Lymphoma of Bone: Long Term Results in Patients Treated with Vincristine - Adriamycin - Cyclophosphamide and Local Radiation

Abstract

Primary lymphoma of bone (PLB) is an unusual but well-recognized extranodal presentation of non-Hodgkin's lymphoma. In most series treatment with radiotherapy alone results in a cure rate of approximately 40%. Between January 1972 and December 1982, 26 patients with biopsy proven PLB were treated at the Rizzoli Institute with radiotherapy (4000-5,500 rad) and chemotherapy (vincristine, cyclophosphamide and adriamycin). The minimal clinical staging included complete blood cell counts and serum chemistries, bone radiography, full lung tomography, isotope bone scan, bone marrow biopsy and bipedal lymphoangiograms. At a median follow-up of 13 years (8.5-18.5) there were only three relapses (2 cases of meningeal involvement and 1 recurrence in another bone). No local recurrences nor second tumor in the irradiated field were observed. We conclude that the addition of chemotherapy to radiotherapy results in an excellent cure rate for patients with PLB.
