Abstract
e16254 Background: With the increasing prevalence of hepatic resection for hepatocellular carcinoma (HCC) in the elderly, understanding the impact of preoperative frailty on surgical outcomes is crucial. This multicenter cohort study investigates the association between frailty and both short- and long-term outcomes post-hepatic resection in elderly HCC patients. Methods: This multicenter study involved elderly HCC patients (≥ 70 years) undergoing curative-intent resection at 10 hospitals in China from 2012 to 2021. Frailty was assessed using the Clinical Frailty Scale (CFS), with a score of ≥5 indicating frailty. The primary outcomes were overall survival (OS) and recurrence-free survival (RFS), while secondary outcomes included postoperative 30-day morbidity and mortality, and 90-day mortality. Comparisons were made between patients with and without preoperative frailty. Results: Out of 488 elderly patients, 148 (30.3%) were classified as frail. Frail patients had significantly higher rates of 30-day morbidity (68.9% vs. 43.2%), 30-day mortality (4.1% vs. 0.6%), and 90-day mortality (6.1% vs. 0.9%) compared to non-frail patients (all P < 0.05). Over a median follow-up of 37.7 months, frail patients showed markedly lower median OS (41.6 months [95% CI, 32.0-51.2] vs. 69.7 months [55.6-83.8]) and RFS (27.6 months [23.1-32.1] vs. 42.7 months [34.6-50.8]) than non-frail patients (both P < 0.01). Multivariable Cox regression analysis identified frailty as an independent risk factor for decreased OS (HR 1.61, P = 0.001) and RFS (HR 1.32, P = 0.028). Conclusions: Preoperative frailty is significantly associated with worse short-term and long-term outcomes following hepatic resection in elderly HCC patients. These findings underscore the importance of incorporating frailty assessment into the perioperative and postoperative care of elderly patients undergoing HCC resection.
