Purpose: We evaluated whether adding bevacizumab (Bev) to paclitaxel+carboplatin (TC) could improve outcomes, especially progression-free survival (PFS), in patients with platinum-sensitive recurrent ovarian cancer.
Patients and methods: Among patients with platinum-sensitive recurrent ovarian cancer treated at our hospital from May 2008 to March 2017, PFS was compared between those receiving platinum-based chemotherapy or TC+Bev therapy by propensity score matching analysis.
Results: Nineteen patients received platinum-based chemotherapy and 13 patients received TC+Bev therapy. PFS (the primary endpoint) was 6.31 months in the platinum-based chemotherapy group versus 14.71 months in the TC+Bev group (hazard ratio: 0.304; 95% confidence interval: 0.114-0.8121; p=0.01752). The safety profile was similar to that expected.
Conclusion: Adding Bev to TC prolonged PFS in patients with platinum-sensitive recurrent ovarian cancer and adverse effects were tolerable.
