Abstract
Four adult patients with malignant lymphoma were treated with combination chemotherapy including an alkylating agent, vincristine, procarbazine (in all but one case), and intermittent high-dose prednisone. Twenty to 42 months after initiation of therapy, osteonecrosis of the femoral head developed. This was bilateral in two patients and unilateral in two, and presumably represented a complication of steroid administration, even though three of the patients received only 4 to 6 weeks of therapy. Necrosis of bone may be a low-frequency long-term complication of combination chemotherapy in lymphoma.
