肝硬化和肝内门静脉浸润是影响肝细胞癌（HCC）预后的两个因素，外科医生必须了解安全的肝切除范围，作者自1980年就应用肝实质切除比率（PHRR％）、注射 0.5mg／kg靛氰绿15分钟后的染料滞留率（ICG％）和年龄组成的预测评分（PS）来观察术后的实际预后情况，以回归分析划定PS＞50分将死于肝功能衰竭，而PS<50分者均能存活。
Liver cirrhosis and intrahepatic portal vein invasion are two factors affecting the prognosis of hepatocellular carcinoma (HCC). Surgeons must understand the extent of safe hepatic resection. The authors applied a hepatoreapeutic ratio (PHRR%) and injected 0.5 mg/kg since 1980. The rate of dye retention (ICG%) and the age-predicted score (PS) after 15 minutes of kg cyanine cyanide green were used to observe the actual postoperative outcomes. Regression analysis delineated PS>50 points for death due to liver failure. Those with PS <50 can survive.
