Abstract

Objective: We attempted to investigate the safety and efficacy of alternative weekly topotecan dosing in a heavily pretreated Taiwanese population with recurrent epithelial ovarian cancer (EOC) and primary peritoneal carcinoma (PPC). Materials and methods: We retrospectively reviewed the medical records of patients with recurrent EOC and PPC who had been treated with weekly topotecan between November 2008 and May 2012. Topotecan was given at a dose of 2.75-4mg/m2 via a 30-minute intravenous (IV) infusion on Days 1, 8, and 15 of a 28-day cycle until disease progression or unacceptable toxicity occurred. Results: Thirty-two patients were identified and 24 (75%) of them had received at least two previous regimens of chemotherapy; the median number of treatment courses was seven. The main toxicities (Grades 3 and 4) were anemia in seven (21.9%), neutropenia in six (18.8%), and thrombocytopenia in two patients (6.2%). No deaths were attributable to the therapy. Overall, seven patients (21.9%) showed a partial response (PR), while seven patients (21.9%) with stable disease (SD) were observed. Furthermore, we found a favorable response and toxicity profile in patients who received the lowest dose intensity (2.75mg/m2). The median progression-free survival (PFS) and overall survival (OS) were 3 months [95% confidence interval (CI) 2.7-3.2] and 20 months (95% CI 11.1-28.9), respectively. Conclusion: Topotecan administered as a weekly dosage (2.75-4mg/m2) seems to be a tolerable regimen with modest activity in a Taiwanese population. Although the lower dose schedule showed a higher response with a better toxicity profile, further studies with more cases are needed to confirm this finding.
