title: Results of 90 consecutive hepatectomies for hepatocellular carcinoma: a multivariate analysis of survival.
abstract: The surgical results and postoperative management of 90 patients with hepatocellular carcinoma (HCC) who underwent hepatectomy were reviewed, and clinical factors relating to HCC were analyzed to determine what type of HCC responds best to hepatectomy. The patients consisted of 69 men and 21 women. Serum anti-hepatitis C virus was positive in 76.9% of patients and hepatitis B surface antigen was positive in 18.9%. The operative procedures consisted of right lobectomy in six patients, left lobectomy in seven, right hepatic segmentectomy in eight, left lateral segmentectomy in 13, two adjoining subsegmentectomy in 17, subsegmentectomy in 29, and partial hepatectomy in 10. Liver cirrhosis was confirmed histopathologically in 63 patients. There were two operative deaths and two other in-hospital deaths. During the follow-up period, HCC recurred in 64 of the remaining 86 patients at the following sites: liver in 56 patients (87.5%), bones in four (6.3%), lymph nodes in three (4.7%), and lung in one (1.6%). Transcatheter arterial chemoembolization was performed in 22 of the patients with recurrence, transcatheter arterial chemoembolization in combination with percutaneous ethanol injection was performed in 14, hepatectomy was performed in six, and irradiation with Linac x-rays was performed in eight. The cumulative 3- and 5-year survival rates were 63.8% and 37.8%, respectively. Univariate and multivariate analyses of factors influencing survival disclosed that having a single HCC nodule of up to a maximal diameter of 4.0 cm, an absence of intrahepatic metastasis, and a functional liver reserve estimated as clinical stage I contributed significantly and independently to increasing the survival rate.
