Aim.Differential immunohistochemical parameters of primary liver cancer and liver metastases of ductal pancreatic cancer (DPC) were studied in puncture trephine biopsy of the liver of 23 patients with hepatocellular carcinoma (HCC), 2 patients combined hepato-cholangiocellular cancer (CHCC), 15 patients cholangiocellular cancer (CCC) and 12 patients with metastatic DPC.Results.It was found that HCC liver is characterized by high levels of expression of HepPar 1 and alpha-fetoprotein, the lack of expression of MUC1 mucins, MUC5AC and CA125, and variable expression of CK8, CK7, SK19 and CK20, Unidirectional transport of both wettable and nonwettable liquids on an asymmetrically concave structured surface which depends on the degree of tumor differentiation and embodiment.Cholangiocellular liver cancer differs from others expressed desmoplastic stroma, high levels of expression of cytokeratins 7 and 19, MUC1 and MUC5AC, lack expression of HepPar 1 and variable expression of alpha-fetoprotein, cytokeratin 8 and20.
Insolid and trabecular patterns of CHCC expression of HepRar 1, AFP and CK20 were determined, and in ductual patterne- CK7 and CK19 were determined.CCC and liver metastases of DPC which have the similar microstructure were characterized with the same spectrum characteristic of expressed cytokeratin (SK7, + 19, + 20, +) and mucin (MUC1 + MUC5AC +), and variable expression of CA125 and CA19-9.Conclusion.Therefore, the differential diagnosis in immunohistochemistry of liver trepanobioptate between CCC and liver metastases of DPC is only possible based on the data Motivation, organization and career teachers: the Italian case of computed tomography or ultrasound examination of the liver and pancreas.
