Detailed follow-up of patients with chronic hepatitis has resulted in increased diagnosis of hepatocellular carcinoma (HCC) in patients without cirrhosis. Despite numerous studies on hepatic resection, the prognostic factors for intrahepatic recurrence and survival are not well known for patients with HCC without cirrhosis.Methods

Among 349 patients with HCC treated in the past 13 years, cirrhosis was absent in 126 patients (36 per cent). Curative hepatic resection was carried out in 100 (79 per cent) of these patients. Risk factors for intrahepatic recurrence and prognostic factors for survival were evaluated by univariate and multivariate analyses.Results

Postoperative morbidity and mortality rates were 22 and 3 per cent respectively. The 5- and 10-year disease-free and overall survival rates were 31 and 50 per cent, and 22 and 47 per cent respectively. Blood loss, surgical resection margin, intrahepatic metastasis, portal vein invasion and extent of hepatic resection were independently associated with overall survival. However, the only risk factors for intrahepatic recurrence were portal vein invasion and hepatitis C virus (HCV) infection. The former was related to early recurrence while the latter was related to later recurrence. The 5-year disease-free survival rate was 58 per cent in patients with hepatitis B virus infection while it was 6 per cent in patients with HCV infection (P < 0ยท001).Conclusion

In the treatment of HCC without cirrhosis, major hepatectomy is advocated to prevent early recurrence. Liver transplantation may be required for patients with HCV infection.
