Chinese experience with hepatectomy for huge hepatocellular carcinoma.

Abstract

The risks and outcome of hepatic resection for huge hepatocellular carcinoma (HCC) are controversial. The clinical records of 525 patients who underwent resection of HCC greater than 10 cm in diameter were studied retrospectively. Prognostic factors for long-term survival were evaluated by univariate and multivariate analyses. Postoperative complications were common (26.8 per cent) and five patients (0.9 per cent) required relaparotomy. The 30-day mortality rate was 2.7 per cent. The main causes of postoperative death were liver failure (nine patients) and bleeding (four). The 3-, 5- and 10-year crude survival rates after liver resection were 34.3, 16.8 and 2.9 per cent respectively. Prognostic factors for long-term survival mainly reflected the biological behaviour of the tumour. They can be used only as a guide in balancing the risks of operation against the potential benefits of resection in a patient in poor general condition or with poor liver function. They cannot be used alone to exclude patients from liver resection with curative intent. Liver resection for huge HCC was safe and efficacious. It should be used to treat patients with acceptable surgical risks and resectable tumours.
