Phase II study of cisplatin and vinorelbine in squamous cell carcinoma of the cervix: a gynecologic oncology group study.

Abstract

To evaluate the efficacy and toxicity of intravenous cisplatin and vinorelbine as combination chemotherapy in patients with advanced or recurrent squamous cell carcinoma of the cervix. Between August 1997 and January 2001, 73 patients with advanced or recurrent squamous cell carcinoma of the cervix were entered onto this study. Eligible patients had received no prior therapeutic chemotherapy, except when administered concurrent with primary radiation therapy. The initial doses administered were cisplatin 75 mg/m(2) every 4 weeks and vinorelbine 30 mg/m(2) weekly. Subsequent doses were unchanged, reduced, escalated, or omitted according to observed toxicity and protocol guidelines. Patients were evaluated for response and toxicity using standard Gynecologic Oncology Group criteria. Of 73 patients, 67 were eligible and assessable. The overall response rate was 30% (five complete and 15 partial responses). The overall median response duration was 5.5+ months. The major toxicity was neutropenia, with 16% grade 3 and 67% grade 4 reported. Gastrointestinal and neurotoxicity were infrequent and mild. The combination of cisplatin and vinorelbine has moderate activity in advanced or recurrent squamous cell carcinoma of the cervix. Additional study of this regimen in a phase III setting is justified in this patient population.
