In accord with the expression status of PTPN14 and PTEN, these ICC patients were divided into four groups: (1) PTENhigh/PTPN14high (n=12); (2) PTENhigh/PTPN14low (n=13); (3) PTENlow/PTPN14high (n=15); (4) PTENlow/PTPN14low (n = 17). This evidence concerns the gene PTPN14 and intrahepatic cholangiocarcinoma.
