In case of urothelial carcinoma, expression of MUC1 showed varied trend, starting from lack of expression (N = 38 or 12%), focal reactivity (N = 12 or 4%, mean H-score 0.057±0.01) to moderate (N = 147 or 46%, mean H-score 1.02±0.05) and intense immunoreactivity (N = 117 or 37%, mean H-score of 2.86±0.02). Here, MUC1 is linked to urothelial carcinoma.
