Abstract

Objective: To evaluate the rate and associated factors of pelvic lymph node metastasis in cervical cancer patients undergoing radical surgery at the National Hospital of Obstetrics and Gynecology. Subjects and Methods: A retrospective cross-sectional study was conducted on 445 patients with stage I–IIA cervical cancer who underwent surgery between 2020 and 2024. Results: The rate of pelvic lymph node metastasis was 15.3%. Significant associated factors included lymphovascular space invasion (OR: 13.5; p < 0.001), stromal invasion > 5 mm (OR: 4.99; p = 0.001), pelvic lymph nodes ≥ 1 cm detected on MRI (OR: 6.42; p < 0.001), and FIGO 2018 stage ≥ IB2 (OR: 1.95; p = 0.012). Conclusion: The incidence of pelvic lymph node metastasis in cervical cancer patients undergoing radical surgery at the National Hospital of Obstetrics and Gynecology is 15.3%. Prognostic factors associated with the risk of pelvic lymph node metastasis include lymphovascular space invasion (LVSI), pelvic lymph node size greater than 10 mm on MRI, and the preoperative clinical stage. Preoperative assessment of these factors may facilitate the indication for sentinel lymph node biopsy and aid in the selection of an optimal treatment strategy.
