Postradiation sarcoma of bone in Hodgkin disease

Abstract

We report 16 cases seen in the Memorial Sloan-Kettering Cancer Center (MSKCC) during the past 50 years. These patients had been treated with external radiation for Hodgkin disease and had developed sarcomas in the field 4-31 years after the diagnosis of Hodgkin disease. Most of the tumors (12 of 16) occurred in the chest wall. There were three tumors of the pelvis and an unusual osteosarcoma of the femur following treatment for a primary Hodgkin disease of the femur. The tumors were predominantly osteosarcomas (9). In addition, there were five malignant fibrous histiocytomas, one fibrosarcoma, and one chondrosarcoma. Prognosis was poor; the mean survival was 12 months. Survival of patients with other primary cancers who developed radiation sarcomas was not significantly different from that of patients with Hodgkin disease. Hodgkin disease is now the most common tumor among radiation-induced sarcomas in previously normal bone and has surpassed breast cancer, which was previously the most common original tumor.
