Objective To investigate the expression of forkhead box A2 (FXOA2) in intrahepatic cholangiocarcinoma (ICC), and to analyze the relationship between expression of FOXA2 and patient's prognosis after liver resection. Methods Data of 85 patients with ICC who underwent liver resection between 2009 and 2013 in our hospital were collected retrospectively. The expression of FOXA2 was examined by immunohistochemical method, and then the relationship between expression of FOXA2 and patient's prognosis/clinical characteristics was expplored. Results Among the 85 patients, low expression of FOXA2 was detected in 50 patients, whereas high expression was observed in 35 patients. More advanced tumor (Ⅲ+Ⅳ staging) was found in patients with low expression of FOXA2 than patients with high expression of FOXA2 (P < 0.050). The median follow-up time was 15-month (3-73 months). During the follow-up period, 65 patients suffered from recurrence, whereas 64 patients died. The multivariate analysis suggested that, postoperative recurrence was associated with low expression of FOXA2, evaluated preoperative CA19-9, and presence of satellite nodes (P < 0.050). Low expression of FOXA2, evaluated preoperative CA19-9, nerves invasion, and presence of satellite nodes were predictive factors for postoperative prognosis (P < 0.050). Conclusion Low expression of FOXA2 was associated with poor prognosis for patients with ICC after liver resection, and FOXA2 may be a prognostic factor for ICC.
