OBJECTIVE: To evaluate whether the addition of topotecan can improve the efficacy of carboplatin and paclitaxel in first-line treatment of advanced epithelial ovarian cancer. METHODS: Meta-analysis was performed using a random effects model. RESULTS: Four randomized controlled trials with a total of 3632 patients were identified and included in the meta-analysis. No significant differences were observed in terms of progression-free survival (P=0.400), overall survival (P=0.502) and overall response rate (P=0.953) between patients treated with topotecan plus carboplatin and paclitaxel versus carboplatin and paclitaxel. However, there were significantly higher rates of grade 3-4 leucopenia (P=0.024), neutropenia (P<0.001), anaemia (P<0.001), and thrombopenia (P<0.001) in the topotecan plus carboplatin and paclitaxel group. No significant differences were observed in grade 3-4 nausea (P=0.352) and vomiting (P=0.092) between these two groups. CONCLUSION: Topotecan plus carboplatin and paclitaxel did not improve survival outcomes and caused more haematological toxicity for advanced ovarian cancer.
