PRELIMINARY RESULTS OF HEPATIC RESECTION FOR CENTRALLY LOCATED LARGE HEPATOCELLULAR CARCINOMA

Abstract

Resection of large hepatocellular carcinoma (HCC) located in the central portion of the liver remains a surgical challenge. Over a 2 year period, from July 1989, 19 HCC patients whose main tumour (mean diameter 11.3 cm, range 6–19cm) was located in the central part of the liver (defined as Couinaud's segments IV, V, VIII) had liver resections. Liver cirrhosis was found in 14 patients (73.7%). Extended major hepatectomy could be performed in only three patients. The operative morbidity and mortality were 26.3% and 0%, respectively. The resection margin in 14 patients was less than 1 cm. At the time this paper was written 11 patients were alive and disease free, five patients survived longer than 30 months. The 1 year disease free rate and survival rate were 73.7% and 84.2%, respectively. The preliminary results reveal that with careful preservation of non-tumourous liver, resection of centrally located large HCC is still advocated even in a cirrhotic liver, and that the resection margin width should not be a major concern.
