Baseline demographics, surgical management, pathology data, and outcomes were analyzed using descriptive statistics, and survival analysis.  \nResults: Postoperative histology of the 110 patients meeting inclusion criteria was 45. 5% grade 3 endometrioid, 36.4% serous, 10.9% clear cell, and 7. 3% carcinosarcoma. On final pathology, 63.7% were stage 1, and 23. 6% were stage 3C with positive nodes. A total of 63 patients (57. 3%) had a PA lymph node dissection (56 bilateral, 7 unilateral) in addition to the pelvic SLN. Among this group, 5. 8%(95% confidence interval 1. 2%–16 .0%) had a positive PA node despite a negative pelvic SLN. Among those with a negative pelvic SLN and no adjuvant chemotherapy (n = 75), the rate of distant recurrence was 14.7%, and 3-year recurrence-free survival was 71.9% . Conclusion: The rate of isolated PA node metastasis in high-grade endometrial cancers despite a negative pelvic SLN may be significantly higher than the accepted rate of isolated PA node metastasis in low-grade endometrial cancer. This supports adjuvant treatment decisions continuing to incorporate primary tumor pathology and molecular classification.  \nK E Y WO R D S  \nendometrial cancer, lymph node assessment, sentinel lymph node biopsy, surgical staging, uterine cancer  \nThis is an open access article under the terms of the Creative Commons Attribution-NonCommercial-NoDerivs License, which permits use and distribution in any medium, provided the original work is properly cited, the use is non-commercial and no modifications or adaptations are made.  \n© 2024 The Author(s) .
