Sarcopenia Imperils Postoperative Long-Term Survival in HCC Patients with Metabolic Dysfunction-Associated Fatty Liver Disease: A Propensity Score Matching Analysis.

Abstract

Recent research has suggested that sarcopenia may have an impact on postoperative outcomes. The number of hepatocellular carcinoma (HCC) patients with metabolic dysfunction-associated fatty liver disease (MAFLD) has increased significantly over time. The main objective of this study was to investigate the impact of sarcopenia on the prognosis of HCC patients with MAFLD after hepatectomy. A multivariate Cox proportional hazards model and a propensity score matching (PSM) analysis were conducted to ensure that the baseline characteristics were similar. Kaplan‒Meier survival curves were used to compare the prognosis of the two groups. This study involved 112 HCC patients with MAFLD undergoing hepatectomy. Sarcopenia was indicated as a risk factor for both recurrence-free survival (RFS) and overall survival (OS) in HCC patients with MAFLD after multivariate analysis (p=0.002 and 0.022, respectively). After conducting PSM analysis, Kaplan‒Meier survival curve analysis revealed significant differences in both the RFS and OS between the two groups (p=0.0002 and p=0.0047, respectively). All results showed that sarcopenia had a poor prognosis for HCC patients with MAFLD undergoing hepatectomy. In summary, our study suggests that sarcopenia might be a risk factor for OS and RFS in HCC patients with MAFLD who underwent hepatectomy through multivariate analysis and PSM analysis. Sarcopenia imperils postoperative survival rates and this finding can guide clinical decision-making. For postoperative patients, preventing or treating sarcopenia can potentially improve survival outcomes for patients with HCC and MAFLD.
