Background: Hepatic resection is an accepted therapeutic modality for hepatocellular carcinoma (HCC). Over the past 2 decades, liver surgery has evolved to a refined and deliberate operation. In the present study surgical results are analyzed with an aim toward further improving the treatment of HCC.
Methods: We studied 303 patients with HCC who underwent a hepatic resection at 2 university hospitals from 1985 through 2000. Living-related liver transplantation was a procedure of choice in 1 patient with early staged HCC. Fifty-five percent of the patients had associated cirrhosis. Before the operation, the liver function was mainly evaluated with the indocyanine green retention test.
Results: The mortality rate within 30 days after the operation was 1.6%. One-, 3-, 5-, 10-, and 15-year cumulative survival rates were 84%, 67%, 51%, 20%, and 11%, respectively. The tumor stage I and II groups showed superior survival rates to those of the tumor stage III and IV groups, respectively, and the difference was statistically significant. The disease-free survival curves, however, showed the rate to be 27% at 5 years and 11% at 10 years.
Conclusions: Although the surgical results have greatly improved in the treatment of HCC, the recurrence rate is still high. In carefully screened patients with poor liver function and small HCC, liver transplantation enhances the possibility of cure.
