Total skeletal muscle area at the L3 level was normalized for height in m2 as the skeletal muscle index (SMI). All patients were divided into low and high SMI group according to the median SMI.Results: Ninety-six consecutive patients were included eventually, with 49 patients in the high-SMI group and 47 patients in the low-SMI group. In the low-SMI group, the median overall survival (OS) was 459.00 days (95% CI, 334.76– 583.24 days), and the 3-, 6-, and 12-month OS rates were 100%, 89.4% and 68.1%, respectively. In the high-SMI group, the median OS was not reached, and the 3-, 6-, and 12-month OS rates were 100%, 98% and 79.5%, respectively (p 0.05).Conclusion: SMI is associated with the prognosis of HCC patients receiving interventional therapy combined with immunotherapy and targeted therapy, and sarcopenia is an independent risk factor for OS. However, sarcopenia does not seem to predict the occurrence of adverse events.Keywords: hepatocellular carcinoma, sarcopenia, immune checkpoint inhibitors, tyrosine kinase inhibitors, transarterial chemoembolization
