Retrospective analysis of the CYVADIC regimen in advanced soft tissue sarcomas.

Abstract

We performed a retrospective review of our data obtained with the original CYVADIC regimen in 31 consecutive patients with advanced soft tissue sarcomas. The treatment consisted of cyclophosphamide 500 mg/m2 i.v. from day 1, vincristine 1.5 mg/m2 in days 1 and 5, doxorubicin 50 mg/m2 i.v. on day 1, and dAcarbazine 250 mg/m2 i.v. from days 1 to 5, repeated every 3 weeks. An objective response was observed in 11/31 patients (35.5%). There were 2 complete remissions (6.5%) lasting 23 and 2 months respectively and 9 partial responses (median duration 7 months, range 1-23). No change was observed in 14 patients, and 6 patients showed progression after a median of 2 cycles of chemotherapy. Toxicity was similar to that already described with this regimen, with alopecia, nausea, vomiting and myelosuppression being the most important side effects. In particular, the median WBC nadir was 1,900/mm3 (range 400-3,600/mm3) whereas the platelet nadir was 181,000/mm3 (range 80,000-358,000/mm3); no patient developed congestive heart failure, and no treatment related death was observed. Still today, after 10 years of use, the CYVADIC regimen is very widely employed as a standard treatment for recurrent or metastatic soft tissue sarcomas, although the original positive results have been confirmed only by a few authors. In our retrospective analysis of a totally unselected population of patients, we too observed a lower activity which is, however, according to a recent review, similar to the mean value of responses obtained in the whole population of treated patients reported in the literature.
