Abstract
BACKGROUND
The aim of this study was to clarify clinicopathologic characteristics of, and to evaluate an aggressive treatment strategy for, hepatocellular carcinoma with biliary tumor thrombi.
METHODS
From 1980 to 1999, a total of 132 patients underwent hepatectomy for hepatocellular carcinoma. Of these, 17 patients had macroscopic biliary tumor thrombi and were retrospectively analyzed.
RESULTS
The operative procedures included right hepatic trisegmentectomy (n = 1), right or left hepatic lobectomy (n = 11), and segmentectomy or subsegmentectomy (n = 5). In 13 patients, tumor thrombi extended beyond the hepatic confluence and was treated by thrombectomy through a choledochotomy in 8 patients and extrahepatic bile duct resection and reconstruction in 5 patients. The 3- and 5-year survival rates were 47% and 28%, respectively, with a median survival time of 2.3 years. These survival rates were similar to those achieved in 115 patients without biliary tumor thrombi. In a multivariate analysis, expansive growth type and solitary tumors were independent prognostic variables for favorable outcome after operation, whereas biliary tumor thrombi was not a significant prognostic factor.
CONCLUSIONS
Surgery after appropriate preoperative management of hepatocellular carcinoma with biliary tumor thrombi yields results similar to those of patients without biliary involvement. Hepatectomy with thrombectomy through a choledochotomy appears to be as effective as a resection procedure.
