The aims of the present study were to investigate the expression of minichromosome maintenance complex component 7 (MCM7) and determine its association with tumor proliferation and invasion in pathological tumor (pT)a and pT1 papillary urothelial neoplasia. The MCM7, MCM3 and Ki67 proteins were detected in 154 cases of urothelial neoplasia using immunohistochemical analysis. The expression of MCM7 significantly increased (P<0.001) as the pathological stage and grade progressed between inverted papilloma, papillary urothelial neoplasm of low malignant potential (PUNLMP), pTa tumor and pT1 tumor...
