BackgroundIn the Gynecologic Cancer Intergroup International Collaboration on Ovarian Neoplasms 7 (ICON7) trial, bevacizumab improved progression-free survival in patients with ovarian cancer when used in combination with first-line chemotherapy and as a single-drug continuation treatment for 18 cycles. In a preliminary analysis of a high-risk subset of patients, there was also an improvement in overall survival. This study aims to describe the health-related quality-of-life (QoL) outcomes from ICON7.MethodsICON7 is a randomised, multicentre, open-label phase 3 trial. Between Dec 18, 2006, and Feb 16, 2009, after a surgical procedure aiming to debulk the disease, women with International Federation of Gynecology and Obstetrics (FIGO) high-risk stage I-IV epithelial ovarian cancer were randomly allocated (1:1) by computer program and block randomisation to receive either six cycles of standard chemotherapy (total 18 weeks) with carboplatin (area under the curve 5 or 6) and paclitaxel (175 mg/m(2)) alone or with bevacizumab (7·5 mg/kg) given intravenously with chemotherapy and continued as a single drug thereafter (total 54 weeks). The primary QoL endpoint was global QoL from the European Organisation for Research and Treatment of Cancer quality-of-life questionnaire-core 30 at week 54, analysed by ANOVA and adjusted for baseline score. Analyses were by intention to treat. The ICON7 trial has completed recruitment and remains in follow-up. This study is registered, number ISRCTN91273375.Findings764 women were randomly assigned to the standard chemotherapy group and 764 to the bevacizumab group. At baseline, 684 (90%) of women in the standard chemotherapy group and 691 (90%) of those in the bevacizumab group had completed QoL questionnaires. At week 54, 502 (66%) women in the bevacizumab group and 388 (51%) women in the standard chemotherapy group provided QoL data. Overall, the mean global QoL score improved during chemotherapy by 7·2 points (SD 24·4) when analysed for all women with data at baseline and week 18. The mean global QoL score at 54 weeks was higher in the standard chemotherapy group than in the bevacizumab group (76·1 [SD 18·2] vs 69·7 [19·1] points; difference 6·4 points, 95% CI 3·7-9·0, p<0·0001).InterpretationBevacizumab continuation treatment seems to be associated with a small but clinically significant decrement in QoL compared with standard treatment for women with ovarian cancer. The trade-off between the prolongation of progression-free survival and the quality of that period of time needs to be considered in clinical practice when making treatment decisions.FundingRoche and the National Institute for Health Research through the UK National Cancer Research Network.Copyright © 2013 Elsevier Ltd.
