| 3 | Hepatocellular carcinoma in nonalcoholic fatty liver disease:A growing challenge显示文摘Nonalcoholic fatty liver disease(NAFLD)is the most common cause of liver disease worldwide,and its prevalence increases continuously.As it predisposes to hepatocellular carcinoma both in the presence and in the absence of cirrhosis,it is not surprising that the incidence of NAFLD-related hepatocellular carcinoma would also rise.Some of the mechanisms involved in hepatocarcinogenesis are particular to individuals with fatty liver,and they help explain why liver cancer develops even in patients without cirrhosis.Genetic and immune-mediated mechanisms seem to play an important role in the development of hepatocellular carcinoma in this population.Currently,it is consensual that patients with NAFLD-related cirrhosis should be surveilled with ultrasonography every 6 mo(with or without alpha-fetoprotein),but it is known that they are less likely to follow this recommendation than individuals with other kinds of liver disease.Moreover,the performance of the methods of surveillance are lower in NAFLD than they are in other liver diseases.Furthermore,it is not clear which subgroups of patients without cirrhosis should undergo surveillance.Understanding the mechanisms of hepatocarcinogenesis in NAFLD could hopefully lead to the identification of biomarkers to be used in the surveillance for liver cancer in these individuals.By improving surveillance,tumors could be detected in earlier stages,amenable to curative treatments. | Angelo Z Mattos Jose D Debes Renu Dhanasekaran Jihane N Benhammou Marco Arrese Andre Luiz V Patricio Amanda C Zilio Angelo A Mattos | 2021 | World Journal of Hepatology2021，13，9： | 0 |
