Expression of FOXP1 and FOXO3a in extrahepatic cholangiocarcinoma and the implications in clinicopathological significance and prognosis

Aims: Extrahepatic cholangiocarcinoma (EHCC) is a highly malignant tumor with poor prognosis and intrinsic resistance to cytotoxic agents. The molecular mechanisms associated with high malignancy and resistance to chemotherapy and radiotherapy have not been fully elucidated. This study investigated the clinicopathological significances of FOXP1 and FOXO3a expression in EHCC
