FOXM1 and intrahepatic cholangiocarcinoma: In view of the overexpression of FoxM1 in ICC tissues, the downregulation of FoxM1 in adjacent peritumoral tissues and the negative correlation of the expression of FoxM1 with the prognosis of patients with ICC, we speculate that FoxM1 may play a role as an oncoprotein in the development of ICC.
