[Phase II study of cisplatin in cervical and endometrial carcinomas]

A phase II group study of cisplatin for cervical and endometrial carcinomas was carried out in 19 institutes throughout Japan. The patients entered consisted of 62 women with cervical and 7 with endometrial carcinoma of whom 39 and 4 were evaluable, respectively. Cisplatin was administered in either of two regimens; 10-20 mg/m2 i.v., on days 1-5, or 50-100 mg/m2 i.v., on day 1, every 3 to 4 weeks. The responders comprised 4 CRs and 10 PRs for cervical carcinoma and 1 CR and 2 PRs for endometrial carcinoma, and the response rates were 35.9% and 75.0%, respectively. The response rates by histological classification were 39.4% (13/33) for squamous cell carcinoma and 16.7% (1/6) for non-squamous cell carcinoma. Response rates analysed by lesion site were 33.3% for primary tumors, 36.8% for local lesions and 33.3% for metastases. Furthermore, the response rate among patients without any prior chemotherapy was 44.4% vs. 16.7% for those with prior chemotherapy. Adverse effects included nausea and vomiting (95.3%), anorexia (93%), anemia (72.1%), leucopenia (60.5%) and elevation of BUN (16.3%). Adverse effects were tolerable. We concluded from these results that cisplatin is among the most efficacious and useful drugs against cervical (and endometrial) carcinoma(s).
