Abstract:
A wide range of cell and tumor markers including the blood group-related isoantigens A, B, O(H) and T-Ag, the cell markers DCA(F36/22) and epithelial membrane antigen (EMA), and the oncogene-related proteins RAP-5p21 and ORP-p21 were investigated by means of immunohistochemistry in selected biopsies from 36 bladder cancer patients with the aim of ascertaining which are of value in patients' survival. A heterogeneous distribution of positivity was found for each marker. In addition, EMA immunostaining correlated significantly (p < 0.05) with patient survival. We conclude that immunohistochemical detection of EMA may provide additional prognostic information in bladder cancer patients.
