Purpose: After curative resection for hepatocellular carcinoma (HCC), the five-year survival rate ranges between 30～50%; however, this might be different from the actual survival rate. The actual 5-year survival rate and prognostic factors following curative resection for HCC were analyzed.
Methods: A retrospective analysis was performed on 63 HCC patients, who had undergone curative resection, between 1998 and 1999.
Results: A total of 63 cases, including 53 men and 10 women, were reviewed. The median age was 49 years old. Pathologic T stage I, II, III and IV were observed in 1, 17, 38 and 7 cases, respectively. The actual 1-, 3- and 5-year survival rates were 85.7, 69.8 and 57.0%, respectively, with a median survival time of 58 months. The actual 1-, 3- and 5-year disease free survival rates were 68.1, 51.9 and 50.2%, respectively, with a median disease free survival time of 46 months. Thirty-one patients had recurrence, mostly within one year (65%), indicating a poor survival rate, with an actual 5-year survival rate of 5%. A satellite nodule, the pT stage, recurrence of tumor, time to recurrence (within one year), and presence of extrahepatic metastasis were found to be prognostic factors influencing the survival rate of HCC patients. However, microvessel invasion caused a difference in the survival rate, but without statistical significance (p=0.08). A satellite nodule, microvessel invasion and the pT stage were found to be factors influencing the disease free survival rate of HCC patients. No statistically related factors, with the exception of the pT stage, were found in a multivariate analysis.
Conclusion: The actual 5-year survival and disease free survival rates were 57.0 and 50.2%, respectively. The time to recurrence and pT stage were found to be factors influencing the survival rate of patients with a hepatocellular carcinoma. Further advanced studies will have to be carried out for the active treatment of HCC cases with a pT stage III or IV to reduce recurrence.
