Abstract

BACKGROUND: GATA3 (GATA-binding protein 3) expression in urothelial carcinoma (UC) and mammary carcinomas has been recently reported. However, to the authors' knowledge, studies examining GATA3 staining of metastatic UC (MUC) in cytology specimens are lacking. Delta Np63 (p40) has been shown to be expressed highly selectively in squamous cell carcinomas (SCCs) but the literature concerning the expression of p40 in UC is limited and controversial. In the current study, the authors evaluated the usefulness of GATA3 and p40 in the diagnosis of MUC in cytology specimens. METHODS: Thirty-two MUC cytology cases and 44 controls (22 UC cases and 22 SCC cases) were stained for GATA3, p40, and p63 and nuclear staining intensity and the percentage of positive cells were recorded and compared. RESULTS: MUC cytology cases stained positive for GATA3, p40, and p63 in 78.13%, 80.65%, and 61.29% of cases, respectively, with moderate/strong staining intensity. MUC cases had a significantly higher percentage of GATA3 positivity compared with SCC controls (P
