Clinicopathologic features of patients with hepatocellular carcinoma surviving >10 years after hepatic resection.

Abstract：

BACKGROUND:This study was performed to clarify the clinicopathologic features of hepatocellular carcinoma (HCC) patients surviving >10 years after hepatic resection. METHODS:Between January 1971 and April 1987, 142 patients underwent hepatic resection. Thirty-nine patients who died of surgical morbidity (surgical mortality rate: 27.5%) were excluded from this study. Among the 103 patients who survived and were observed for >10 years after surgery, 12 patients (11.7%) survived >10 years after hepatectomy. The surviving patients were divided into 2 groups: 10-year survivors (n = 12) and nonsurvivors (n = 91). A comparative study between the two groups was made. RESULTS:Preoperative liver function tests such as the indocyanine green retention test at 15 minutes and albumin levels showed that 10-year survivors had better liver function than nonsurvivors. With regard to virus markers, 5 of 12 patients (41.7%) were positive for hepatitis B surface antigen (HBs-Ag) and the incidence of hepatitis B virus-related HCC was significantly higher than in nonsurvivors (P = 0.020). The results also showed that 4 of 12 long term survivors had hepatitis C virus (HCV) antibody and 1 patient did not have any HCV antibody or HBs-Ag. In two other patients, the HCV antibody was not measured and HBs-Ag was negative. Among four patients with the HCV antibody, the serum HCV RNA concentration, measured by branched DNA probe assay, was <0.5 in 3 patients and 1.72 in 1 patient. Therefore, the HCV RNA concentration tended to be lower in 10-year survivors. Tumor recurrence occurred in 8 of the 10-year survivors. Solitary recurrence was observed in five patients whereas multiple recurrence was observed in three patients. All five patients with solitary recurrence underwent a second resection. CONCLUSIONS:Based on the results of the current study, good liver function, HBs-Ag positivity, and a low concentration of serum HCV RNA in HCV-related HCC should be considered potentially good predictors of a long term survival.
