Textbook outcomes of hepatocellular carcinoma patients with sarcopenia: A multicenter analysis.

ABSTRACT

BACKGROUND: The impact of sarcopenia on textbook outcome (TO) after hepatectomy in hepatocellular carcinoma (HCC) patients remains unclear. This study aimed to investigate the association between sarcopenia and TO, to clarify its long and short-term prognostic value, and to develop a nomogram model based on sarcopenia and TO for survival prediction. METHODS: Patients who underwent HCC resection between January 2012 and March 2017 in three large hospitals in Fujian were retrospectively recruited and divided into sarcopenia and non-sarcopenia groups based on skeletal muscle index (SMI) values. TO was defined as no 30-day morality, no 30-day readmission, negative margins, no prolonged hospital stay, and no major complications. Multivariate regression was used to screen for clinical factors associated with TO. Nomograms of overall survival (OS) and recurrence-free survival (RFS) after hepatectomy for HCC were developed. RESULTS: A total of 1172 patients were included in the study. The TO rates were 28.74% (121/421 patients) in the sarcopenia group and 43.4% (326/751 patients) in the non-sarcopenia group. The results showed that sarcopenia was an independent predictor of TO (p < 0.001), TO was an independent predictor of perioperative treatment-related sarcopenia (PTRS)(p = 0.002), and TO was an independent predictor of OS and RFS (p < 0.001). Nomogram models based on sarcopenia and TO were generated and accurately predicted OS and RFS at 1, 3, and 5 years. CONCLUSION: Both sarcopenia and TO are independent predictors of OS and RFS after HCC resection. Sarcopenia was an independent predictor of TO. Sarcopenia influenced long-term survival by affecting short-term postoperative outcomes.
