Primary liver cancer is one of the most common digestive system malignancies worldwide, with hepatocellular carcinomas accounting for about 90% of cases. It has a concealed onset, rapid progression, high degree of malignancy, and is difficult to treat, which presents a serious threat to people's life and health (1). At present, the primary treatment methods for liver cancer include hepatectomy, liver transplantation, transcatheter arterial chemoembolization, systematic treatment, and combined therapy, among which surgical resection is the most important (2,3).The previously reported prognostic variables affecting liver cancer resection included age, performance status, tumor number, body mass index (BMI), and other factors, which significantly improved the incidence of postoperative complications and the long-term survival rate of liver cancer patients. However, sarcopenia is being gradually explored and studied as a new prognostic factor. Sarcopenia refers to a degenerative loss of muscle mass, strength, and function, with a prevalence of between 11% and 30% in patients undergoing surgery for digestive system cancers (4).At present, numerous studies have shown that sarcopenia is an independent risk factor for poor short-and long-term prognosis after hepatectomy for liver cancer. Berardi et al. (5) recently reported on 234 patients undergoing hepatectomy for liver cancer in the JAMA Surgery and analyzed the relationship between sarcopenia and short-term prognosis after hepatectomy. Their study pointed out that sarcopenia was associated with poor short-term prognosis following malignant liver tumor resection, especially in terms of 90-
