Purpose. To analyze quality of life (QOL) in a randomized, placebo-controlled phase III trial concluding that the addition of concurrent and maintenance bevacizumab (Arm 3) to carboplatin and paclitaxel prolongs progression-free survival in front-line treatment of advanced ovarian cancer compared to chemotherapy alone (Arm 1) or chemotherapy with bevacizumab in cycles 2-6 only (Arm 2). Patients and methods. The Trial Outcome Index of the Functional Assessment of Cancer Therapy-Ovary (FACT-O TOI) was used to assess QOL before cycles 1, 4, 7, 13, and 21; and 6 months after completing study therapy. Differences in QOL scores were assessed using a linear mixed model, adjusting for baseline score, and age. The significance level was set at 0.0167 to account for multiple comparisons. Results. 1693 patients were queried. Arm 2 (p<0.001) and Arm 3 (p<0.001) reported lower QOL scores than those in Arm 1. The treatment differences were observed mainly at cycle 4, when the patients receiving bevacizumab (Arm 2 and Arm 3) reported 2.72 points (98.3% CI: 0.88-4.57; effect size = 0.18) and 2.96 points (98.3% CI: 1.13-4.78; effect size = 0.20) lower QOL respectively, than those in Arm 1. The difference in QOL scores between Arm 1 and Arm 3 remained statistically significant up to cycle 7. The percentage of patients who reported abdominal discomfort dropped over time, without significant differences among study arms. Conclusion. The small QOL difference observed during chemotherapy did not persist during maintenance bevacizumab. (C) 2012 Published by Elsevier Inc.
