irradiation and chemotherapy for primary treatment of osteogenic sarcoma.

Combined modality treatment was given in nine patients of osteogenic sarcoma
wherein the tumor was unresectable because of location or amputation was refused.
This alternative to massive surgery comprised hypofractionated irradiation,
intra-arterial infusion of the radiosensitizer 5'-bromodeoxyuridine (BUdR) and
adjuvant systemic chemotherapy. Local control was achieved in seven of the nine
patients. Four survived, all without evidence of disease at 6, 7.1, 8.8, and 10.5
years after completion of irradiation. Pulmonary metastases developed in six
patients--of whom one survives, following high-dose pulmonary irradiation and
additional chemotherapy. Significant soft-tissue injury occurred in five
patients. On the basis of our experience, we believe that new approaches using
modifications of external beam irradiation with different fractionation schedules
or better radiosensitizing compounds may hold promise for patients with
non-resectable osteosarcoma.
