Significance of frailty in prognosis after hepatectomy in older patients with hepatocellular carcinoma.
590 Background: An aging society has come, and “Frailty” is becoming increasingly important in surgery. Recently, clinical frail scale (CFS), which is simple criteria for frailty, has been reported to be useful for prognostic prediction of non-cardiac surgery (Ann Surg. 2018). Herein we report a new knowledge about frailty for patients with hepatocellular carcinoma (HCC) undergoing hepatectomy. Methods: Eighty-one patients over 75 years who underwent hepatectomy for HCC between 2007 and 2018 were enrolled in this study. Frailty was diagnosed as CFS≥4, and patient were divided into 2 groups, frailty (n = 17) and no frailty (n = 64). Clinicopathological factors were compared between 2 groups. Results: Patients’ background, such as age, gender, preoperative comorbidity, and liver function showed no significant difference between 2 groups. Regarding tumor factors, frailty group showed significant larger tumor diameter, more advanced stage (p < 0.05) and tendency of high PIVKA-II (p = 0.15) compared with no frailty group. Frailty group showed significant high CRP level (p < 0.01), high modified Glasgow prognostic score (mGPS, p = 0.04) and tendency of high neutrophil-lymphocyte ratio (NLR, p = 0.14). Frailty group also showed tendency of higher rate of postoperative complication (p = 0.11) and longer postoperative hospital stay (p = 0.09). Overall and disease-free survival rate were significantly worse in frailty group (p = 0.03). In univariate analysis for overall survival, AFP≥10, PIVKA-II≥400, frailty and mGPS high (1, 2) were prognostic factor. Multivariate analysis revealed that frailty was independent prognostic factor. In univariate analysis of disease-free survival, only frailty was detected as prognostic factor. Conclusions: Frailty is an independent prognostic factor for HCC patients who underwent hepatectomy.
