BACKGROUND: In the present study we undertook a retrospective analysis of @entity1086 to assess whether histologically determined hepatic artery (HA) invasion and portal vein (PV) invasion can be considered prognostic factors. METHODS: Seventy-one @entity1 who had undergone radical resection for @entity1086 between 1995 and 2008 at University of Tsukuba were selected from the database for analysis. @entity1 who required extended surgery for para-aortic lymph node @entity3 were also included. Correlation between invasion of the HA and the PV and prognosis and other clinicopathologic factors were analyzed. RESULTS: There were two postoperative deaths among the 71 @entity1 . Pathological invasion of the HA was confirmed in 16 (22.5%) cases and PV invasion was confirmed in 15 @entity1 . @entity1 with invasion of the HA had a significantly poorer prognosis than those without HA invasion (P < 0.0001). Additionally, in univariate analysis, gender (male), positive para-aortic lymph node @entity3 , PV invasion, and HA invasion were identified as significant poor prognostic factors. In multivariate analysis, only HA invasion was an independent prognostic factor (Odds Ratio 0.323; P = 0.029). CONCLUSIONS: Invasion of the HA is a crucial prognostic factor in @entity1 with @entity1086 .

Invasion of the hepatic artery is a crucial predictor of poor outcomes in XXXX .
