Docetaxel and carboplatin chemotherapy for treating patients with stage IVB or recurrent non-squamous cell carcinoma of the uterine cervix: a phase II study.

Background: This phase II study evaluated the efficacy and safety of docetaxel/carboplatin chemotherapy for treating patients with stage IVB or recurrent non-squamous cell carcinoma of the uterine cervix.

Methods: A total of 50 patients with International Federation of Gynecology and Obstetrics stage IVB or recurrent non-squamous cell carcinoma of the uterine cervix were enrolled and administered docetaxel at a dose of 60 mg/m, followed by carboplatin at a dose based on the area under the receiver operating characteristic curve of 6. The treatments were repeated every 21 days until disease progression or unacceptable adverse events. Except for two patients, 48 were eligible for evaluation. Another patient withdrew consent before treatment; adverse events were evaluated in 47.

Results: The response rate was 47.9% with 5 patients achieving complete response, 18 partial response, 14 stable disease, and 6 progressive disease. The disease control rate was 77.1%. With a median follow-up duration of 368 days, the median progression-free survival and overall survival were 6.1 months (95% CI 5.5-8.6) and 15.8 months (95% CI 18.2-28.3), respectively. The most frequent grade 3 and grade 4 hematological toxicity was neutropenia, with 38 patients (81%) having grade 4 and 4 (9%) having grade 3 neutropenia. The non-hematological toxicities were mainly grade 1 or 2 in severity.

Conclusion: Docetaxel/carboplatin chemotherapy was effective, with a higher disease control rate and well-tolerated chemotherapeutic regimen for patients with stage IVB or recurrent non-squamous cell carcinoma of the uterine cervix.
