ABSTRACT
@#BACKGROUND. As of 2015 39,1% of all new cancer cases in Mongolia were HCC having the highest prevalence and it has increased by 4% to the previous year. (Health indicator – 2015, CHD). Although there are quite a lot researches have been done on general cause and impacting factors of HCC, the relevance between the mechanism leading to eventual cancer and the risk factors is still unknown yet. PURPOSE: To define the relevance of the beta-catenin and P53 expression in HCC with the risk factors of HCC in Mongolia. RESULT: 1. 50% of HCV infection in men is related with alcohol consumption and 40% alcohol combined with tobacco consumption. HBV infection has relevance of 46% with tobacco and 52,8% with alcohol consumption. 2. In the first phase of research in 21 HCC cases beta-catenin was identified in cell nucleus and cytoplasm after immunohistochemistry. CONCLUSION: 1. It was to observe that HCV infection is commonly combined with alcohol consumption in HCC cases. 2. Although beta-catenin expression was high in HCV, HBV infection and alcohol high risk group, the P53 expression was high among alcohol high risk group. Р < 0.05
