ABSTRACT
Despite a low risk of liver failure and preserved liver function, non-cirrhotic hepatocellular carcinoma (HCC) has a poor prognosis. In the current study, we evaluated an active regulator of SIRT1 (AROS) as a prognostic biomarker in non-cirrhotic HCC. mRNA levels of AROS were measured in tumor and non-tumor tissues obtained from 283 non-cirrhotic HCC patients. AROS expression was exclusively up-regulated in recurrent tissues from the non-cirrhotic HCC patients (P=0.015) and also in tumor tissues irrespective of tumor stage (P<0.001) or BCLC stage (P<0.001). High mRNA levels of AROS were statistically significantly associated with tumor stage (P<0.001), BCLC stage (P=0.007), alpha fetoprotein (AFP) level (P=0.013), microvascular invasion (P=0.001), tumor size (P=0.036), and portal vein invasion (P=0.005). Kaplan-Meir curve analysis demonstrated that HCC patients with higher AROS levels had shorter disease-free survival (DFS) in both the short-term (P<0.001) and long-term (P=0.005) compared to those with low AROS. Cox regression analysis demonstrated that AROS is a significant predictor for DFS along with large tumor size, tumor multiplicity, vascular invasion, and poor tumor differentiation, which are the known prognostic factors. In conclusion, AROS is a significant biomarker for tumor aggressiveness in non-cirrhotic hepatocellular carcinoma.
