The results on CD10 IHC staining in our study was consistent with those in most of previous studies investigated CD10 IHC expression in urothelial carcinoma (Abdou, 2007; Bahadir et al., 2009; Atique et al., 2014), thus prompting us to examine the association between CD10 mRNA expression level in urothelial carcinoma and patients’ clinicopathologic parameters and its impact on prognosis using RT-PCR. Here, MME is linked to urothelial carcinoma.
