Retrospective analysis of uterine involvement in low grade serous ovarian carcinoma.

Low grade serous ovarian carcinoma (LGSOC) accounts for 2.5% of all ovarian carcinoma more affects younger women than high grade serous ovarian carcinoma. Hysterectomy is performed routinely for LGSOC treatment, but fertility sparring surgery (FSS) is feasible for some early stages. Currently, there is no study about uterine involvement in LGSOC. We evaluate uterine involvement in LGSOC patients and aim to identify pre-operative predictive factors. Retrospective observational study of LGSOC patients treated between January 2000 and May 2022 in the Hospices Civils de Lyon. All cases were viewed, reviewed or approved by an expert pathologist. Among 535 serous ovarian carcinomas, 26 were included. Most patients (73 %) had FIGO III disease. Median OS was 115 months and median PFS was 42 months. Uterine involvement was found in 58 % patients who underwent hysterectomy (14/24), serosal involvement was the most frequent type of involvement (n = 13, 54 %). Myometrial involvement was found in 8 patients (33 %) and was associated with serosal involvement (7/8). Among patients with a macroscopic disease-free uterus during exploratory laparoscopy, 31 % had a microscopic serosal involvement. None patient with presumed early stage (FIGO I) were upstaged due to uterine involvement (serosal or myometrial). In patients with stage FIGO IIII, 72 % of uterine involvement were found. Univariate analysis did not show any predictive factor of myometrial involvement. There was no difference on OS nor PFS between patients with or without myometrial involvement. In early stages LGSOC, FSS may be considered for selected patients. In advanced stages, hysterectomy should be performed routinely, since no predictive factor for uterine involvement were identified.
