Abstract

PURPOSE: Soft tissue sarcomas are uncommon primary malignancies. So studies on the effective chemotherapy for soft tissue sarcomas are limited. We started this study to evaluate the effectiveness of VIP (etoposide, ifosfamide, cisplatin) combination chemotherapy for advanced soft tissue sarcomas.
MATERIALS AND METHODS
Thirty patients with recurrent or metastatic soft tissue sarcoma were treated with VIP combination chemotherapy between December 1989 and June 1996. Each patient was given etoposide 75 mg/m2, ifosfamide 1000 mg/m2, cisplatin 20 mg/m2 intravenously for five consecutive days every three weeks. Mesna (sodium-2-mercaptoethansulfonate) was given to avoid the urologic toxicity.
RESULTS
Twenty-eight of 30 patients were evaluable for response, and among the 28 evaluable patients, there were 9 partial response (32%). Duration of response in 9 responders ranged from 4.1 to 16.2 months (median 8.8 months). Overall survival ranged from 1.7 to 41.5 months (median 11 months) and survival was better for patients with partial response (median survival 14.8 months vs. 9.7 months with stable disease vs. 5.1 months with progressive disease p=0.0006). Nausea and vomiting was noted in more than 90% of cycles, but was markedly severe in only 4%. Leukopenia was noted in 60% of cycles, including 11% of cycles with counts <2,000/mm3. There was no treatment related death, but we had to stop chemotherapy in 2 patients due to leukopenia (1 patient) and neurotoxicity (1 patient).
CONCLUSION
Combination of etoposide, ifosfamide, and cisplatin was fairly active for advanced soft tissue sarcoma, with myelosuppresion and peripheral neuropathy being the most serious toxicities.
