163P Global burden and trend of ovarian cancer in high-income countries: A 30-year analysis of disease dynamics

Ovarian cancer is unique among gynaecological cancers in lacking an effective population-level screening strategy, with most cases diagnosed at advanced stage where five-year survival remains below 30%. This makes long-term burden surveillance especially critical for guiding early detection research and health system planning. HICs are particularly important to study as they benchmark cancer control infrastructure and treatment innovation necessary to reduce disease burden at the population level.
