Hepatocellular carcinoma and sarcopenia: a narrative review

Hepatocellular carcinoma (HCC) affects millions of people each year and is associated with high mortality and morbidity. Sarcopenia, a condition of muscle wasting, and decreased muscle performance is common among aging adults, and is associated with poor clinical outcomes. Individuals with HCC and chronic liver disease (CLD) are at high risk of sarcopenia because of the adverse effects of chronic inflammation, endocrine dysfunction, and hyperammonemia on muscle metabolism and adequate nutrition. Our aim is to review the clinical relationship between HCC and sarcopenia, and the assessment and management of these patients.A narrative review based on a literature search using PubMed. Keywords related to HCC and sarcopenia were used to identify relevant articles, primarily those published 2018-2023. The information was synthesized to provide a narrative review focused on the most recent literature.Sarcopenia frequently co-exists with HCC and increases risk for adverse clinical outcomes such as symptom burden, quality of life (QoL), survival, and side effects of antineoplastic therapy. Tools are available to screen, assess and manage patients with HCC, and although there is no specific pharmacologic agent approved for sarcopenia in the United States, multimodal therapy is feasible in daily practice. Comprehensive management by an interdisciplinary team should include nutritional counseling, an exercise regimen and control of symptoms affecting nutrition and function.Sarcopenia has adverse effects on prognosis and tolerability of surgical and medical therapy in HCC. Patients with CLD and/or HCC would benefit from early identification, assessment, and therapeutic intervention. Management should be comprehensive, interdisciplinary, and include both pharmacologic and non-pharmacologic treatments. Further research is needed to identify individual agents that may mitigate muscle wasting and trials are needed to evaluate the benefit of multimodal therapy in HCC.
