    Objective: This study aimed to evaluate the incidence and predict the risk factors of lymph node (LN) metastasis among patients with grossly apparent early?stage epithelial ovarian cancer (EOC). Methods: We retrospectively reviewed the clinicopathologic data and follow?up information of 266 patients who underwent LN dissection for apparent early?stage EOC between January 2018 and September 2022 at the Obstetrics and Gynecology Hospital of Fudan University. Results: Among 266 patients, 44 (16.5%) showed LN metastasis, of which 65.9% and 59.1% presented in the pelvic region and para?aortic region, respectively. Univariate analysis revealed higher LN positivity in patients with high?grade serous carcinoma (HGSC), preoperative imaging suggestive of LN metastasis, bilateral adnexal involvement, lymphovascular space invasion (LVSI), positive peritoneal cytology, and clinical stage IIA. LN metastases were identified in 7.9%, 10.2%, and 39.7% of clinical stage IA/B, IC, and IIA disease cases, respectively. Multivariate analysis confirmed significantly higher LN positivity rates in patients with HGSC, LVSI, and clinical stage IIA. In clinical stage IIA EOC, the 3?year progression?free survival (PFS) rates were 65.8% and 77.4% (P = 0.360) for LN?negative and LN?positive groups, respectively. In clinical stage I EOC, the 3?year PFS rates were 93.5% and 59.4% (P < 0.001) for LN?negative and LN?positive groups, respectively. Conclusions: High?grade serous histology, LVSI, and clinical stage IIA disease are predictive factors for LN involvement in early?stage EOC. In addition, LN metastasis appears to be associated with worse PFS in clinical stage I EOC compared with clinical stage IIA EOC.
