An update on long-term outcome of curative hepatic resection for hepatocholangiocarcinoma

Abstract

Background: Hepatocholangiocarcinoma (HCC-CC) is a rare primary liver cancer. Its long-term prognosis is still not well-defined. Results from the Eastern and Western literature have been conflicting and no conclusions can be drawn. The aim of the present study was to review the long-term outcome of curative hepatectomy for HCC-CC. Patients and methods: Prospectively collected data from December 1991 to 2006 recording patients with primary liver cancer receiving curative hepatectomy were reviewed. Twenty-five patients, 16 men and 9 women with a median age of 48 years, all ethnic Chinese, had HCC-CC. Their long-term outcome of resection was analyzed and compared to that of patients with cholangiocarcinoma (CC) or hepatocellular carcinoma (HCC). Results: The HCC-CC patients had a median tumor size of 7.5 cm. Five of them developed postoperative complications. The median follow-up period was 25 months. All of the patients developed recurrence. The median overall survival was 25.2 months. The HCC-CC and CC groups had significantly worse overall survival than the HCC group (HCC versus HCC-CC, p = 0.012; HCC versus CC, p = 0.001) whereas between them there was no significant difference (p = 0.822). As for disease-free survival, there was no significant difference between the three groups; the median disease-free survival for HCC-CC patients was 13.5 months; that for CC patients, 16.1 months; and that for HCC patients, 19.0 months. All HCC-CC patients died within 120 months of primary surgery. Conclusions: Hepatocholangiocarcinoma entails poor long-term outcome after potentially curative hepatectomy. Other modalities of treatment should be explored in order to prolong survival of patients with this disease. © 2009 Société Internationale de Chirurgie.
