At the diagnosis of hepatocellular carcinoma (HCC), more than 90% of HCC patients present a cirrhosis, a clinical condition often associated to malnutrition. Sarcopenia has been associated with a lower tumor response or poorer survival of patients undergoing various treatments such as surgery or systemic therapies. Transarterial chemoembolization is the treatment of choice for intermediate HCC and is largely used worldwide, but the impact of sarcopenia on its results was poorly studied.
Finding easy ways to detect sarcopenia within daily practice should benefit to patients by better characterizing their prognosis and taking their nutritional status into account in therapeutic decisions.
This study aimed to evaluate the prognostic value of sarcopenia in patients with HCC treated by trans-arterial (chemo)-embolization based on baseline computed tomography (CT) findings and study its impact on objective tumor response and survival outcomes.
Sarcopenia is easy to assess on CT by measuring the skeletal muscle index. A skeletal muscle index (SMI) < 50 cm2/m2 in male and < 39 cm2/m2 in female patients corresponding to sarcopenia was observed in 57.7% of the patients.
Based on SMI analysis measured on baseline imaging, sarcopenia was observed in 57.7% of the patients. After full review of radiological response using mRECIST criteria, sarcopenia was associated with a higher rate of progressive disease. It was also associated with a decrease overall survival even after adjustment with usual risk factors of death.
Sarcopenia is an easy-to-assess radiological biomarker of poor prognosis that should be measured in order to better assess prognosis of HCC patients.
Sarcopenia should be systematically detected at baseline, and induce a targeted intervention mixing nutritional support and physical activity. Further studies are needed to assess the benefit of these strategies in HCC patients.
