A classification of urothelial carcinoma by immunohistochemistry can be done with three immunostains.[1]

General

A simple classification of urothelial carcinoma

 
 
 
 
 
 
 
 
Urothelial carcinoma
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Luminal type
GATA3 +ve
(CK5/6 -ve)
 
 
 
 
 
 
 
Basal type
CK5/6 +ve
(GATA3 -ve)
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Genomically unstable
p16 +ve
 
 
 
Urothelial-like
p16 -ve

The immunoprofile (GATA3 POSITIVE, p16 POSITIVE, CK5/6 negative,) is in keeping with UROTHELIAL CARCINOMA, LUMINAL TYPE, GENOMICALLY UNSTABLE.
The immunoprofile (GATA3 POSITIVE, p16 negative, CK5/6 negative) is in keeping with UROTHELIAL CARCINOMA, LUMINAL TYPE, UROTHELIAL-LIKE.
The immunoprofile (CK5/6 POSITIVE, GATA3 negative) is in keeping with UROTHELIAL CARCINOMA, BASAL TYPE.
