MME and bladder transitional cell carcinoma: For example, Bahadir et al.[7] indicated that CD10 expression may be strongly correlated with high tumor grade and stage in urothelial carcinoma of the bladder, and that CD10 may be associated with tumor progression in bladder cancer pathogenesis; Yildiz et al.[8] found that dual staining by p53 + CK20 cocktail may allow for histologic correlation and diminish the risk of losing the area of interest in limited biopsy specimens.
