Analysis of a series of sixty soft tissue sarcomas in adults treated with a cyclophosphamide-vincristine-adriamycin-dacarbazine (CYVADIC) combination.
From 1976 to 1983, a group of 60 adult patients presenting with metastatic and/or locally advanced soft tissue sarcomas was treated with combination chemotherapy consisting in cyclophosphamide, vincristine, adriamycin, and DTIC (CYVADIC). A tumor response was obtained for 29 patients (48.3%), with 4 (6.7%) cases of complete regression. The median duration of the response was 10 months. Responses were noted in 14/22 patients receiving induction chemotherapy for advanced, and previously nonirradiated, primary tumors; among the patients with metastatic disease tumor regression was recorded in 17/32 patients with pulmonary metastases, but in none of the patients with metastases at other sites. Moreover, the attainment of a response was found to correlated with the patient's general condition, while response duration depended on the histoprognostic grade of the tumors.
