Quality of life predicts overall survival in women with platinum-resistant ovarian cancer: an AURELIA substudy.

ABSTRACT: Background:Women with platinum-resistant ovarian cancer are a heterogeneous group whose median overall survival is 12?months. We hypothesized that their quality of life (QoL) scores would be prognostic. Patients and methods:Data from AURELIA (n?=?326), a randomized trial of chemotherapy with or without bevacizumab, were used to identify baseline QoL domains [EORTC (European Organisation for Research and Treatment of Cancer) QLQ-C30 and OV28] that were significantly associated with overall survival in multivariable Cox regression analyses. Patients were classified as having good, medium, or poor risk. Cutpoints were validated in an independent dataset, CARTAXHY (n?=?136). Multivariable analyses of significant QoL domains on survival were adjusted for clinicopathological prognostic factors. The additional QoL information was assessed using C statistic. Results:In AURELIA, all domains, except cognitive function, predicted overall survival in univariable analyses. Physical function (P?93) risk categories for physical function, median overall survival was 11.0, 14.7, and 19.3?months, respectively (P?44), medium- (13-44), and low- (<13) risk categories for abdominal/gastrointestinal symptoms, median overall survival was 11.9, 14.3, and 19.7?months in AURELIA (P?
