A pilot study of oral S-1 for treating heavily pretreated patients with advanced or recurrent cervical cancer among Chinese population

This pilot study retrospectively aimed to assess the feasibility effectiveness and safety of oral S-1 in heavily pretreated patients with advanced or recurrent cervical cancer (ARCC) among Chinese population. Thirty patients with ARCC who had undergone one or more lines of chemotherapy received oral S-1 (40–60 mg/m(2)) twice daily for 6 weeks. Outcome measurements included tumor response, time to progression (TTP), overall survival (OS) time, and occurrence of adverse events (AEs). The overall response rate was 43.3%. After a median follow-up of 6 months, the median TTP was 4.4 months and the median OS time was 10.2 months. The most frequent grade 3 or 4 AEs were neutropenia (13.3%) and nausea (16.7%). The results of this study show that oral S-1 is effective and well-tolerated in patients with ARCC who were heavily pretreated among Chinese population.
