Chu et al (2000) studied the expression of two of the low molecular weight cytokeratin subtypes, CK7 and CK20, in 435 cases of epithelial neoplasms. They observed CK7 expression in the majority of ...

Useful markers for diagnosis among the primary types are cytokeratin 7(CK7), cytokeratin 20 (CK20), gross cystic disease fluid protein 15 (GCDFP-15), carcinoembryonic antigen (CEA), and uroplakin ...

Low-molecular-weight cytokeratins CK7 and CK20 help define subsets of carcinomas. CK7 is mainly found in tumors of the lung, ovary, endometrium, and breast. CK20 is usually expressed in ...

Immunohistochemistry findings are positive for cytokeratin 7 (CK7) and thyroid transcription factor 1 (TTF-1), and negative for cytokeratin 20 (CK20), caudal type homeobox 2, CA19-9, napsin-A ...

The tumor cells were negative for high-molecular-weight keratin 34bE12 and cytokeratins CK7 and CK20, which are typical of urothelial carcinoma. Prostatectomy was subsequently canceled ...

NICE received an enquiry relating to recommendation 1.2.2.7, which states "Use a panel of antibodies comprising cytokeratin 7 (CK7), CK20, thyroid transcription factor‑1 (TTF‑1), placental alkaline ...

Immunohistochemical staining was positive for CK7, CK20 and GATA3, and negative for S-100, HMB-45 and GCDFP15. Neoplastic cells were positive for periodic acid–Schiff staining. We performed laboratory ...
