Abstract
The surgical results for small hepatocellular carcinomas (HCCs) are not necessarily satisfactory. The resectional therapy for small HCC was evaluated to elucidate its benefits and limitations. Data were analyzed concerning 52 patients having small HCC of <3 cm in diameter and <3 nodules, who underwent hepatic resections from 1978 to 1989. Cumulative and disease-free survival at 5 years after resection were 57% and 37%, respectively. Histologic features, such as differentiation of HCCs, pseudocapsular invasion, and ploidy pattern of nuclear DNA, appeared to be good prognostic indicators. The survival rate of the large-resection group (number of resected segments greater than number of tumor-occupying segments) was significantly better than that in the small-resection group (84% versus 48% at 5 years, P<0.05). Surgical resection of small HCCs is a safe and effective therapy. A large resection appears to provide better patient survival and tumor-free survival compared to a small resection.
