Low-dose-intensity bevacizumab with weekly irinotecan for platinum- and taxanes-resistant epithelial ovarian cancer



Abstract

Purpose The purpose of this study was to evaluate the safety and efficacy of low-dose-intensity bevacizumab and weekly irinotecan as salvage treatment for patients with platinum- and taxanes-resistant advanced epithelial ovarian cancer.MethodsFifty-two patients with platinum- and taxanes-resistant advanced epithelial ovarian cancer received bevacizumab 5 mg/Kg days 1 and 15; irinotecan 60 mg/m2 days 1, 8 and 15. The combined therapy was repeated every 28 days, up to six cycles.ResultsA total of 230 cycles of bevacizumab combined with irinotecan were administrated to 52 patients. Among the 52 patients, 22 patients achieved partial response (42.3 %); 12 patients had stable disease (23.1 %) and 18 patients experienced disease progression (34.6 %). The median progression-free survival and the median overall survival were 8.0 months (95 % confidence interval: 6.74–9.26 months) and 13.8 months (95 % confidence interval: 11.97–15.63 months), respectively. The most frequent grade 3–4 hematologic toxicities were neutropenia (11.5 %) and thrombocytopenia (3.8 %). The non-hematologic toxicities included grade 3 diarrhea (3.8 %) and hypertension (3.8 %). Two patients (3.8 %) were confirmed with deep vein thrombosis. Febrile neutropenia, symptomatic cardiac dysfunction and gastrointestinal perforation were not observed in this study.ConclusionsThe combination of low-dose-intensity bevacizumab and weekly irinotecan was an effective and safe regimen for patients with platinum- and taxanes-resistant epithelial ovarian cancer.
