The purpose of the present paper was to report cases of avascular necrosis of bone (AVNB) arising as a complication of chemotherapy for acute lymphoblastic leukemia (ALL). X-rays and [sup 99m]technicium-MDP bone scans were performed on patients with symptoms of bone pain, whereby five patients out of 850 patients were detected to have avascular necrosis of the femoral head. All had received aggressive chemotherapy with steroids. Two patients were still on therapy for the primary disease. In these patients further chemotherapy was continued without steroids. The median period from diagnosis of ALL to development of AVNB was 29 months. Three patients underwent corrective surgical procedures. To conclude, the data suggest that patients receiving combination chemotherapy, especially those with high cumulative doses, run a risk of developing AVNB. Awareness of this complication is important in order to have an early diagnosis so as to limit disability. [ABSTRACT FROM AUTHOR]
