The Relationship Between Complications and Geriatric-8 Scores in Elderly Patients Who　Underwent Minimal Invasive Surgery for Gynecologic Malignancies

Abstract Background This study examines the correlation between Geriatric-8 (G8) scores and perioperative complications in elderly patients undergoing minimally invasive surgery (MIS) for gynecological malignancies. Given the increasing elderly population and use of MIS, understanding these risks is crucial for improving patient outcomes. Methods A retrospective study at Kobe University Hospital included patients aged 65 and older who underwent MIS for gynecological malignancies between January 2019 and March 2024. G8 scores were calculated from medical records, and complications were defined using the Clavien-Dindo classification or the Common Terminology Criteria for Adverse Events (CTCAE) version 5 grade Ⅱ or higher within 30 days postoperatively and cases that required rehabilitation intervention due to a decline in Activities of Daily Living (ADL). Results Among 68 patients, 24 were in the Complication Group and 44 in the Non-Complication Group. The median G8 score was 12.5 in the Complication Group and 14.5 in the Non-Complication Group (p = 0.008). The Complication Group had significantly lower G8 scores (p = 0.02) in robot-assisted surgeries, while no significant difference was observed in laparoscopic surgeries. Conclusion Lower G8 scores predict higher perioperative complication rates in elderly patients undergoing MIS for gynecological malignancies. The G8 tool effectively predicts perioperative complications in MIS for gynecologic malignancies and aids in treatment decisions.
