Immunohistochemistry of cytokeratin (<scp>CK</scp>) 5/6, <scp>CD</scp>44 and <scp>CK</scp>20 as prognostic biomarkers of non‐muscle‐invasive papillary upper tract urothelial carcinoma

Abstract

We demonstrated that IHC staining for CK5/6, CD44 and CK20 was significantly associated with the clinicopathological characteristics and prognoses of patients with non-muscle-invasive papillary UTUC. The IHC subgroups may be correlated with the molecular characteristics of non-muscle-invasive papillary UTUC.
