Objectives: The purpose of this paper is to analyze the relationship among major gene data and clinical data in HCC by network analysis and word cloud. According to the several covariate we can compare the characteristics. Methods: We used network analysis to visualize the relationships and hidden structure among the genes and clinical covariates collected from 2011-2015 SNU Liver Center in Korea with classification tree, survival tree, SDA correlation circle, network graph, wordle. Results: We find that smoking and obesity is the most important factor of causing HCC prognosis. We can visually recognize these results from the network graphs made by network analysis and wordle. Conclusions: We made the age-specific social network graphs between genes and clinical lab data of HCC in Korea across diagnosis and prognosis.
