Usefulness of Geriatric Parameters in Preoperative Evaluation of Patients Undergoing Minimally Invasive Surgery for Endometrial Cancer: A Retrospective Cohort Study.

Introduction: Patients operated for endometrial cancer (EMCA) are typically elderly with multiple comorbidities, potentially impacting surgical outcomes and survival. This study evaluated the prognostic value of frailty and frailty-related scores in predicting perioperative morbidity and survival in EMCA patients undergoing minimally invasive surgery.

Methods: This retrospective cohort study included 289 patients from the Sentinel Database treated for EMCA at Bern University Hospital (2012-2020). Patients underwent minimally invasive hysterectomy with sentinel lymph node dissection (39%) or additional radical lymphadenectomy (61%). Frailty was assessed using the Age-Adjusted Charlson Comorbidity Index (ACCI), modified Frailty Index (mFI), 5-item mFI (mFI-5), American Society of Anesthesiologists (ASA) scores, and independent parameters. Primary outcomes included perioperative complications, hospital stay, recurrence-free survival (RFS), and overall survival (OS).

Results: Median age was 65 years (range 26-94) and median follow-up was 41 months (0-105). ACCI > 4 (23.2%) was the strongest predictor of postoperative complications (p = 0.025), prolonged hospitalization (p = 0.03), and reduced OS (hazard ratio [HR] 2.57, 95% confidence interval [CI] 1.18-5.60; p = 0.018). Multivariable analysis confirmed ACCI > 4 (HR 2.24, 95% CI 1.02-4.90; p = 0.044), European Society for Medical Oncology (ESMO) risk group (HR 1.61, 95% CI 1.24-2.07; p < 0.001), hemoglobin (HR 1.03, 95% CI 1.00-1.05; p = 0.033), and congestive heart failure (HR 6.29, 95% CI 1.35-29.27; p =0.019) were significant predictors of OS. Radical lymphadenectomy (p < 0.001), ACCI > 4 (p = 0.025), and age > 70 years (p = 0.034) increased complication risks.

Conclusions: ACCI > 4 is a practical tool for preoperative risk assessment and predicting surgical tolerance and survival, and is therefore applicable for guiding surgical decisions and personalized care in patients with EMCA.
