WebAmong the various cytokeratins, the combination of cytokeratins (CKs) 7 and 20 is considered to be the most useful for this purpose. However, there are very few reports in the literature regarding CK7 and CK20 expression in gallbladder carcinoma (GBC). In this paper we studied the immunohistochemical expression of CK7 and CK20 in 42 GBC cases. WebIHC is a hugely popular tool in cancer research and remains the gold standard in clinical cancer diagnostics. Each different type of cancer is associated with specific protein …

Pan-keratin AE1/3-positive, CK7-positive, CK20-negative, and TTF-1-positive tumours suggested thyroid or lung carcinomas. WebCoordinate expression profiles for cytokeratins 7 and 20 (CK7 and CK20) are useful for distinguishing certain types of adenocarcinomas but use for distinction of primary and secondary mucinous tumors in the ovary is limited due to the existence of a number of tumor types exhibiting overlapping CK7/CK20 immunoprofiles; the use of staining distribution … hima systems

WebCK7 immunostain shows proliferating glands at left and a disorderly spread of single cells and cell groups at right, amid hepatocytes. F. CK7 immunostain at higher power shows the stained cells have aberrant nuclei. A B C D E Cholangiocarcinnoma, intrahepatic, in a 72 year old man, poorly differentiated. A. WebWe investigated the expressions of CK7 and CK20 in 289 cases of gastric carcinoma and 225 cases of colorectal carcinoma using a tissue microarray. To evaluate CK7 and CK20 expression patterns of ovarian metastases from gastric or colorectal carcinomas, 54 cases of metastatic carcinomas to the ovary were examined. himatekkim
