Abstract 971P
Background
The growing demand for hepatic resection in elderly hepatocellular carcinoma (HCC) patients highlights the need to understand the impact of preoperative frailty on surgical outcomes. This multicenter retrospective cohort study aimed to investigate the association between frailty and short-term and long-term outcomes following hepatic resection in elderly HCC patients.
Methods
We conducted a multicenter retrospective cohort study on elderly patients (≥70 years) who underwent curative-intent hepatic resection for HCC at 10 Chinese hospitals in China from 2012 to 2021. Frailty was assessed using the Clinical Frailty Scale (CFS), with frailty defined as CFS ≥ 5. Primary outcomes included overall survival (OS) and recurrence-free survival (RFS); secondary outcomes encompassed postoperative 30-day morbidity, 30-day mortality, and 90-day mortality. We compared these outcomes between patients with and without preoperative frailty.
Results
Of the 488 elderly patients, 148 (30.3%) were considered frail. Frail patients experienced significantly higher postoperative 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%) than non-frail patients (all P<0.05). During a median follow-up of 37.7 months (IQR: 20.4-57.8), frail patients demonstrated significantly worse median OS (41.6 months [95% CI, 32.0-51.2] vs. 69.7 months [95% CI, 55.6-83.8]) and RFS (27.6 months [95% CI, 23.1-32.1] vs. 42.7 months [95% CI, 34.6-50.8]) compared to non-frail patients (both P<0.01). Multivariate Cox-regression analysis revealed frailty as a significant predictor for OS (HR 1.61, 95% CI 1.22-2.13, P=0.001) and RFS (HR 1.32, 95% CI 1.03-1.70, P=0.028).
Conclusions
Frailty was significantly associated with adverse short-term and long-term outcomes in elderly HCC patients undergoing hepatic resection. Our findings suggest that frailty assessment should be incorporated into perioperative and postoperative prognosis evaluation, and particular attention should be given to frail elderly patients undergoing this procedure.
