The objective of this study were to evaluate the efficacy of hepatic resection for large hepatocellular carcinomas (HCCs) and examine clinicopathologic factors influencing overall survival after resection of a large HCC. The pre-, intra-, and postoperative factors and long-term outcome of 26 patients with HCCs >10 cm who underwent hepatic resection (group A) were compared with the those of 143 patients with HCCs less than or equal to 10 cm (group B). Hepatic resection for large HCCs can be performed with a mortality rate of 3.8%, which was similar to the rate for group B (2.1%). The overall cumulative survival results for group A (1 year 41.0%, 3 years 29.3%, 5 years 29.3%; median survival 10.1 months) were markedly worse than those for group B (1 year 93.1%, 3 years 74.5%, 5 years 44.7%; median survival 53.4 months) (p < 0.0001). Multivariate analysis identified venous invasion as an independent risk factor of survival of patients with a large HCC. The overall cumulative survival results in patients with venous invasion (1 year 28.0%, 3 years 0%; median survival 6.4 months) were markedly worse than in patients without venous invasion (1 year 64.8%, 3.5 years 64.8%; median survival, 51.8 months) (p < 0.0066). We concluded that hepatic resection can be performed safely for HCCs >10 cm with a low mortality rate. It appears reasonable to believe that hepatic resection is the treatment of choice for large HCCs without venous invasion.
