[Chemotherapy using cisplatin in bone and soft tissue sarcoma]

Cisplatin was used in 14 bone and soft tissue sarcomas. Severe vomiting developed in all cases, but the duration was relatively short. Renal function was disturbed in cases with a higher total dose. This side effect was considered to be the dose-limiting factor of cisplatin. Seven cases showed high-frequency deafness but they did not complain of disturbance during conversation. In seven metastatic osteosarcomas, one was evaluated as a partial response and one as a minor response. No response was observed among three soft tissue sarcomas. Three cases of osteosarcoma receiving cisplatin in adjuvant chemotherapy have been disease-free for 4 and 46 months after resection of pulmonary metastases and for 50 months after resection of the primary tumor. We consider cisplatin to be the first-choice drug in cases resistant to adriamycin or methotrexate, but there are some problems when cisplatin is used in adjuvant chemotherapy, because of its side effects.
