Prospective evaluation of weekly topotecan in recurrent platinum-resistant epithelial ovarian cancer.
Topotecan administered on a weekly basis has been reported to possess antineoplastic activities with lower toxicities than the standard 5-day regimen every 3 weeks. We studied the activity of weekly topotecan regimen in recurrent platinum-resistant epithelial ovarian cancer patients. Ovarian cancer patients with documented platinum-resistant recurrences were treated with weekly intravenous topotecan (4 mg/m(2)) on days 1, 8, and 15 on a 28-day cycle. ⋯ No significant association was observed between best clinical response and patients' initial platinum sensitivity status. The estimated median progression-free survival was 20.9 weeks (95% CI 11.2-30.5) from the start of the weekly regimen. Weekly topotecan is well tolerated in patients with recurrent platinum-resistant ovarian cancer with modest activity.
