Aquaporin‐1 differentiates intrahepatic cholangiocarcinoma from liver metastases of pancreatic ductal adenocarcinoma

open access: yesHistopathology, EarlyView.
Differentiating intrahepatic CCA from PDAC metastatic to the liver is critical for the clinical management of patients with pancreatobiliary cancers. AQP1 has demonstrated an excellent discriminatory performance in this clinical scenario. Aims Differentiating intrahepatic cholangiocarcinoma (iCCA) from metastatic ductal adenocarcinoma of the pancreas ...
