Background This hospital-based analysis was conducted to identify prognostic factors of hepatocellular carcinoma (HCC) in a hepatitis B virus endemic area. Methods. A total of 6381 HCC cases, diagnosed from 1986 to 2002, were enrolled, and 2890 (42.3%) of them were not treated. Survival rates were analyzed by correlation with the national mortality databank. Missing data and correlations among prognostic factors were considered in the analysis. Results. The overall 1-year, 3-year, 5-year, and 7-year survival rates were 44.3%, 24.9%,1.7.1%,and 13%, respectively. Multivariate analysis revealed that the independent factors influencing survival were the initial treatment modality, degree of liver function impairment, hepatitis B surface antigen positivity, tumor status, and (x-fetoprotein. Besides these well-known prognostic factors, high alanine aminotransferase (ALT) levels and a high aspartate aminotransferase (AST)/ALT ratio were identified as independent poor prognostic factors. Conclusions. This study, which considered untreated cases, missing data, and correlations between variables and official survival data sets, provides a large-scale comprehensive survival analysis. According to our results, high ALT and high AST/ALT were independent poor prognostic factors. Therefore, viral activity should be controlled in HCC patients, and patients with elevated AST/ALT ratios should be carefully monitored.
