  abstract     = {{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. Patients with International Federation of Gynecology and Obstetrics (FIGO) stage I were categorized into full staging, fertility-sparing, or partial stagings. Outcomes were overall survival and recurrence free survival, and recurrence rates. Results Among 409 identified patients, 257 (63%) had expansile and 152 (37%) had infiltrative tumors. Patients with expansile tumors had FIGO stage I more frequently (n=243, 95% vs n=116, 76%, p<0.001). For FIGO stage I disease, patients with expansile and infiltrative tumors underwent similar proportions of partial (n=165, 68% vs n=78, 67%), full (n=32, 13% vs n=23, 20%), and fertility-sparing stagings (n=46, 19% vs n=15, 13%) (p=0.139). Patients with expansile FIGO stage I received less adjuvant chemotherapy (n=11, 5% vs n=24, 21%, p<0.001), exhibited better overall and recurrence free survival (p=0.006, p=0.012), and fewer recurrences (n=13, 5% vs n=16, 14%, p=0.011). Survival and recurrence rates were similar across the expansile extent of staging groups. Patients undergoing fertility-sparing staging for infiltrative tumors had more recurrences compared with full or partial stagings, while recurrence free survival was similar across these groups. Full staging correlated with better overall survival in infiltrative FIGO stage I (p=0.022). Conclusions While most patients with FIGO stage I underwent partial staging, those with expansile had better outcomes than those with infiltrative tumors. Full staging was associated with improved overall survival in infiltrative, but not in expansile FIGO stage I. These results provide insight for tailored surgical approaches.}},
