hepatocellular carcinoma(HCC)has emerged as a formidable global health challenge since it ranks the sixth most common malignant tumor and the third most common cause of cancer-related death(1).One of the most important factors in the creation of the increased incidence of HCC is the increasing rate of metabolic syndrome(MS),which is a complex interaction of metabolic abnormalities represented by obesity,insulin resistance,dyslipidemia,and *** was believed that chronic hepatitis B and C were one of the major etiologies of HCC,but additionally,the changed landscape of etiology now points toward MS and its comorbidities,such as non-alcoholic fatty liver disease,as major contributors in promotion of development and progress of HCC(2,3).
