[Current approaches to the combination therapy of osteogenic sarcoma]

The results of treatment of 315 cases of osteogenic sarcoma are presented. Available methods of primary tumor therapy fail to prevent dissemination of neoplastic disease by blood circulation. However, following a prophylactic course of chemotherapy (adriamycin, vincristine, cyclophosphamide, sarcolysine), 3- and 5-year survival rates in 45 cases of limb amputation for osteosarcoma increased to 38.1% and 30.5%, respectively. No recurrences were observed in 39 patients with extensive segmental resection of bone who preoperatively received intra-arterial infusions and radiation therapy; the 3-year survival rates were a high as 43.9% and patients showed good performance. The method offers good advantages in the treatment of patients with osteogenic sarcoma.
