They were allocated into three groups aocording to their PSI: group Ⅰ, PSI≤10%; group Ⅱ, 10%＜PSI＜30%;and group Ⅲ, 30%≤PSI. Of these, selected 122 Child-Pugh stage A (Child A) subjects were included in analysis (a mean follow-up period of 5.9±5.4 years, range 6 mo-21 years).RESULTS: No significant correlation between PSI and cumulative probability of HCC Incidence was observed.Cumulative probability of Child A to B progression was tended to be higher in group Ⅲ than in group Ⅰ, and significantly higher in group Ⅲ than in group Ⅱ (62% vs 34%, 62% vs 37%; P = 0.060, ＜0.01; respectively).Cumulative probability of varices tended to be higher In group Ⅲ than in group Ⅰ (31% vs 12%, P = 0.090). On multivariate analyses, significant correlation between PSI and Child A to B progression was observed, and no significant correlation between PSI and HCC incidence or varices progression was observed.CONCLUSION: Patients with LC-C of Child A will progress to Child B rapidly after their PSI reaches 30% or higher.PSI can be used to predict occult progressive porto-systemic shunting and liver failure non-invasively. It indicates that PSI may play an important role in follow-up of the portosystemic hypertension gradient for outpatients with LC unlike hepatic venous catheterization.展开更多
