Outcomes of patients with early stage mucinous ovarian carcinoma: a Dutch population-based cohort study comparing expansile and infiltrative subtypes.

Objective: This study aimed to assess the outcomes of patients with early stage mucinous ovarian carcinoma based on subtype (expansile vs infiltrative).

Methods: We retrospectively analyzed all surgically treated patients with mucinous ovarian carcinoma in the Netherlands (2015-2020), using data from national registries. Subtypes were determined, with any ambiguities resolved by a dedicated gynecologic pathologist.
