Abstract

Background/Aims
The prognosis of hepatocellular carcinoma (HCC) is affected by stage as well as liver function. We analyzed the survival outcome of early stage HCC in Child class C patients and advanced HCC in Child class A patients.
Methods
Among 453 HCC patients with good performance status, Group A included 33 consecutive Child class C patients with early stage (I, II) HCC, and Group B included 45 consecutive Child class A patients with advanced stage (III, IV) HCC. We investigated the clinical characteristics, cirrhotic complications, and prognostic factors related with survival in each group, and compared overall survival between two groups.
Results
Age, prothrombin time, total bilirubin and Model for End-Stage Liver Disease (MELD) scores were significantly higher in Group A. Male sex, platelet count, albumin, sodium (Na), hepatitis B virus, alpha fetoprotein (AFP) and portal vein thrombosis were significantly higher in Group B. Complications of cirrhosis such as variceal bleeding, ascites, and hepatic encephalopathy were increased in Group A (P<0.05). Patients with an elevated AFP (>400 ng/mL) tended to exhibit poor survival as it increased in Group A (P=0.084). MELD scores>15 (Hazard ratio[HR] 17.84, 95% confidence interval [CI] 3.70-85.93, P<0.001), stage IV (HR:3.27, 95% CI 1.10-9.75, P=0.033), and absence of HCC treatment (HR: 3.70, 95% CI 1.06-12.50, P=0.040) were independent poor prognostic factors in Group B. Median overall survival was 24.6 months (95% CI 10.6-38.4) for Group A and 13.5 months (95% CI 4.6-22.3) for Group B (P=0.278). In the HCC treatment group, there were no significant differences of median overall survival between Group A and Group B, respectively (27.1 vs. 15.7 months, P=0.338). In patients with conservative treatment, Group A and Group B had a significantly different median overall survival of 13.6 and 2.5 months, respectively (P=0.012). In patients of Group B, median overall survival was significantly higher in patients who received treatment of HCC compared to those who did not, respectively (15.7 vs. 2.5 months, P<0.001).
Conclusions
Overall median survival was not different between both groups. However, in Child class A patients with advanced stage HCCs, the cumulative median survival was higher in patients who received treatment of HCC compared to those who did not. Therefore, advanced stage HCC patients with good liver function should be considered for HCC treatments.
