Abstract

Background: Pelvic and para-aortic lymphadenectomy remains the standard procedure for nodal staging in apparent early-stage ovarian cancer, but it is associated with considerable morbidity and lacks clear evidence of improving survival. Sentinel lymph node mapping may offer a less invasive alternative while still enabling accurate upstaging in a sub-set of patients with occult lymph node metastasis. Primary Objective: This study aims to evaluate the negative predictive value of the sentinel lymph node technique for detecting lymphatic metastases in early-stage ovarian cancer compared with systematic pelvic and para-aortic lymphadenectomy (gold standard). Study Hypothesis: The sentinel lymph node technique is non-inferior to systematic lymphadenectomy for detecting lymphatic metastasis. Trial Design: This is a multi-center phase III clinical trial. Eligible patients with confirmed early-stage ovarian cancer will undergoing sentinel lymph node mapping and a subsequently complete staging surgery, including systematic lymphadenectomy. The concordance between both methods will be analyzed. Major Inclusion/Exclusion Criteria: Inclusion: Women aged =18 years, with histologically confirmed epithelial ovarian malignancy in apparent International Federation of Gynecology and Obstetrics I to II stage, planned for staging surgery either at the time of initial surgery (after intra-operative frozen section confirmation) or after a deferred histologic diagnosis. Exclusion: Age <18 years, previous vascular or lymphatic pelvic/aortic surgery, previous lymphoma or abdominopelvic tumors, allergy to Technetium-99m or indocyanine green, pregnancy/lactation. Primary Endpoint: Negative predictive value of the sentinel lymph node technique compared to systematic lymphadenectomy for lymph node metastasis. Sample Size: The planned sample size is 100 patients with negative sentinel lymph node results to ensure adequate statistical power (80%) to detect a negative predictive value for the sentinel lymph node technique above 95%. An interim analysis will be performed once 50% of the recruitment has been reached to adjust the exact total sample size. Recruitment period is estimated at 24 to 36 months in 11 high-volume Spanish centers. Estimated Dates for Completing Accrual and Presenting Results: Patient accrual: November 2025 to November 2028. Final results expected: January 2029. Trial Registration: NCT06963268 © 2025 European Society of Gynaecological Oncology and the International Gynecologic Cancer Society. Published by Elsevier Inc.
