Abstract
Response rates of metastatic soft part sarcomas to chemotherapy have varied from 27 and 44% for our ALOMAD and OMAD protocols to 46–55% reported for CYVADIC. The present combination, CYOMAD, consists of the induction part of ALOMAD (vincristine, high‐dose methotrexate with citrovorum factor rescue, Adriamycin and DTIC) alternating with a condensed version of CYVADIC (cyclophosphamide, vincristine, adriamycin and DTIC). Forty‐one patients with advanced soft‐part sarcomas were entered on the CYOMAD program of whom 36 were considered evaluable. Complete responses (CR) were seen in four patients and partial (PR) in five patients for a major response rate of 25%. Responders had an overall longer survival than nonresponders (20 versus 13 months). Toxicity was substantial with both gastrointestinal side effects and myelosupression common. Possible Adriamycin cardiotoxicity was noted in four patients. Cyomad offered no therapeutic advantage over previous protocols and was even less well tolerated than some. Cancer 50:1724‐1727, 1982.
