Abstract Background: Owing to the wide spread perception of a possible benefit from paclitaxel in the second-line situation the Nordic Gynecologic Oncology Group (NGOG) conducted two prospective phase II studies of paclitaxel single agent treatment (175 mg/m2, three-hour i.v. infusion with standard pre-medication every third week) in patients with relapsing or progressing epithelial ovarian cancer following platinum. Patients and methods: Between 1992–1994 138 patients in total were enrolled of whom 136 received paclitaxel and were included in the toxicity and survival analysis, while 112 were evaluable for response. Results: The overall response rate (CR + PR) was 28% with 16 patients achieving a CR (14%). The estimated median (range) time to progression was 4.1 (0.7–60.7) months. The projected four-year overall survival was 7%, with a median (range) of 9.6 (0.3–60.7) months. A multivariate logistic regression analysis showed that platinum resistance, and WHO performance status at baseline, independently correlated with survival at all three time points (median survival time 9.6, 18, and 24 months). Patients with platinum sensitive tumors and WHO performance status 0 had a median survival of 25.6 months compared to 7.0 months for the rest of the patients (P ≤ 0.0001). No serious toxicity was registered. Conclusion: Paclitaxel could safely be administered in an outpatient setting using this schedule. Patients with platinum sensitive tumors and a good performance status were most likely to survive. However, these patients are also most likely to respond to re-treatment with a platinum compound. With reference to the reasonably good tumor control and limited toxicity observed in this study, we conclude that paclitaxel single agent therapy is a viable option in the salvage situation, which in some patients can give long-lasting responses. However, although responses can be induced in a significant number of patients, the survival figures remain poor.
