✦ Synopsis

BACKGROUND.

Successful chemotherapy for patients with soft tissue sarcoma (STS) has been limited by a lack of active drugs. The most effective single agents are doxorubicin, dacarbazine, and, more recently, ifosfamide. Previously the most widely used combination has been CYVADIC (cyclophosphamide, vincristine, doxorubicin, and dacarbazine). In one randomized trial, ifosfamide was superior to cyclophosphamide; two nonrandomized studies also reported favorable results.

Etoposide monotherapy was successful in 8%; the effectiveness of cisplatin was 5-23%. In view of these findings, the authors treated STS patients with an etoposide, cisplatin, and ifosfamide (VIP) combination.

METHODS.

The eligibility criteria included histologically confirmed, inoperable, metastatic or locally recurrent STS; a World Health Organization (WHO) performance status of 0 -2; a maximum age of 75 years; and progressive, measurable disease. A total of 104 patients were treated from January 1990 to June 1997. The median age of the patients was 42.4 years. The patients were treated with a combination of etoposide (100mg/m 2 for 5 days), ifosfamide (2000mg/m 2 for 2 days), and cisplatin (20mg/m 2 for 5 days) once a month via a peripheral vein. The treatment response and the toxicity were assessed according to WHO criteria.

RESULTS.

Of 104 evaluable patients, 47 responded. The overall response rate was 46% (complete response: 10%; partial response: 36%). In 43 patients the disease remained stable (41%). Remission duration was 4.6 months. Toxicity was moderate. The main adverse events were alopecia (100%), nausea and vomiting (73%), and leukopenia (29%).
