Extrahepatic recurrence after curative resection of hepatocellular cancer / 中华普通外科杂志

ABSTRACT

Objective To investigate the risk factors of extrahepatie recurrences after curative resection of primary hepatocellular carcinoma (HCC). Methods Clinicopathologic data of 238 curative resected cases of primary HCC were retrospectively reviewed for parameters affecting postoperative extrahepatic recurrences. Results During a median follow-up of 34 months (7 - 78 months), extrahepatic recurrences were observed in 32 out of 238 patients (13.4%). According to univariate analysis, the risk factors for extrahepatic recurrences were preoperative serum a-fetoprotein (AFP) level of > 1000 ng/ml,aspartate aminotransferase level of > 50 IU/L, presence of hepatic vein invasion, neighboring organ invasion, tumor satellites, and lack of tumor capsule formation. Preoperative serum AFP levels of > 1000 ng/ml, hepatic vein invasion, neighboring organ invasion proved to be independent risk factors by multivariate analysis. Conclusions Extrahepatic recurrences after curative resection of HCC was found to be related to preoperative serum AFP level of > 1000 ng/ml, hepatic vein invasion, and neighboring organ invasion.
