Task: Question Generation
Input (English): The aim of this study was to evaluate the prognostic value of the serum CA-125 level for complete responders after 6 cycles of primary adjuvant paclitaxel/carboplatin chemotherapy in advanced epithelial ovarian cancer.', 'The clinical data of 123 complete responders after 6 cycles of primary adjuvant paclitaxel/carboplatin chemotherapy for epithelial ovarian cancer FIGO stages III and IV were collected between January 1997 and March 2007. All patients were divided into 3 groups according to the serum CA-125 level after 6 cycles of the chemotherapy: group I (< 10 U/ml), group II (10-21 U/ml), and group III (> 21 U/ml). The effect of the serum CA-125 level on survival was evaluated using the Kaplan-Meier method and Cox proportional hazard analysis.', 'The median progression-free survival was 26, 14, and 10 months, and the median overall survival was 105, 42, and 37 months in groups I, II, and III, respectively (p < 0.05). The lower serum CA-125 level and optimal debulking surgery were prognostic factors for improving survival (p < 0.05).
Output (English): Is serum CA-125 level after 6 cycles of primary adjuvant chemotherapy a useful prognostic factor for complete responders ' survival in patients with advanced epithelial ovarian cancer?
