The chemotherapy included three cycles of adriamycine, cyclophosphamide, vincristine, dacarbazine and five cycles of adriamycine and cyclophosphamide. 34 patients were randomized for additional beta-Interferon (Fiblaferon) treatment (10(5) U/kg daily for 3 weeks followed by 3 times a week for 21 weeks). 38 patients were not treated with Fiblaferon. The response rate was 96% including 35% complete and 61% partial remissions. Preoperative chemotherapy improved remarkably the resectability of the primary tumor without enhancing complication rates. The cumulative proportion surviving was 21% for the interferon group and 6% for the patients not treated with interferon. The cumulative recurrence free survival rate, however, was 5% for both groups. The median survival time was 19 months and the median recurrence free survival time 10 months. A serious side effect of chemotherapy was bone marrow depression (73%) resulting in 1 week delay of drug administration per cycle. The median of administered drug dosages was 87-100% of the recommended dosages. Side effects of beta-Interferon commonly decreased with time and were fever reactions (55%), shaking chills (29%), cardiovascular reactions (16%).(ABSTRACT TRUNCATED AT 250 WORDS) | lld:pubmed |
