In a comparative study of topotecan and paclitaxel in patients previously treated for ovarian carcinoma with platinum based chemotherapy (n = 112 and 114, respectively), the response rate (95% CI) was 20.5% (13%, 28%) versus 14% (8%, 20%) and median time to progression 19 weeks versus 15 weeks (hazard ratio 0.7 [0.6, 1.0]), for topotecan and paclitaxel, respectively.
