Phase II evaluation of topotecan and navelbine in patients with recurrent ovarian, fallopian tube or primary peritoneal cancer.

Abstract

OBJECTIVE:

To assess the efficacy and toxicity profile in patients with recurrent ovarian or primary peritoneal cancer treated with topotecan at 2.5 mg/m(2) days 1 and 8 plus vinorelbine at 25 mg/m(2) days 1 and 8 every 3 weeks.

MATERIALS AND METHODS:

Eligibility criteria included patients with recurrent primary peritoneal or epithelial ovarian cancer with either platinum-resistant or platinum-sensitive disease. Patients were required to have a performance status of <or=2 and normal hepatic and renal function. Response to therapy and toxicity were assessed using standard criteria. Chi square and Student's t-tests were used as appropriate. Survival was assessed with Kaplan-Meier method.

RESULTS:

All 40 patients enrolled were assessable for response. The median age of the patients was 58 years (range 30-82). Median treatment-free interval was 4.0 months. A total of 216 cycles of chemotherapy were administered with a median of 5.0 cycles per patient. Overall median TTP with this treatment regimen was 19 weeks (range 2-136 weeks). The response rate was 30% overall, and the response for platinum-sensitive and platinum-resistant patients was 44% (95% CI:22-69%) and 18% (95% CI:5-40%) respectively. Median progression-free survival was 3.0 months (range 1-9 months). Median overall survival was 16.4 months (range 1.5-51.7 months). Assessment of toxicity by patient showed 58% demonstrating grade 3/4 neutropenia with the vast majority being uncomplicated. No severe non-hematological toxicity was observed.

CONCLUSION:

Administration of topotecan and navelbine is feasible with demonstrable activity and tolerable toxicity. This regimen may be considered especially in platinum-sensitive patients if a non-platinum based doublet is desired.
