Abstract Background: Prior studies evaluating diet quality in relation to ovarian cancer survival are sparse, and date none have assessed or diet-quality change after diagnosis. Methods: In the prospective Ovarian Prognosis And Lifestyle (OPAL) study, scores were calculated using data from food frequency questionnaires completed pre-diagnosis (n = 650) 12 months' post-diagnosis 503). We used Cox proportional hazard models estimate adjusted ratios (HR) 95% confidence intervals (CI) for association between survival. Results: During median follow-up of 4.4 years, 278 women died cancer. There was no evidence an pre- progression-free, overall, cancer–specific No advantage observed who had either improved their consumed a high-quality both before months Conclusions: Higher not associated with better outcomes this cohort Impact: Diet is important range health but may improve diagnosis
