A classification of urothelial carcinoma by immunohistochemistry can be done with three immunostains.[1]
General
- A large meta-analysis showed two markers (CK5/6, GATA3) can subclassify ~90% of urothelial carcinoma into prognostic groups.[2]

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.
