ABSTRACT
Hepatocellular carcinoma (HCC) is a common malignant tumor and patients with HCC often have liver cirrhosis, with an extremely high 5-year recurrence rate and poor prognosis even after curative treatment. In recent years, sarcopenia has attracted more and more attention as a poor prognostic factor for various malignant tumors; however, there is still a lack of studies on the association between skeletal muscle index and prognosis of HCC in China. Evidence in foreign countries has shown that sarcopenia may be an a negative prognostic factor for HCC patients. This article reviews the etiology and possible pathogenesis of HCC-related sarcopenia and related intervention measures including nutritional supplementation, appropriate physical exercise, and medication, in order to provide a reference for related studies in China.
