[Cellular proliferation, expression of p53, EGFR and apoptosis index of healthy mucosa of the bladder with TCC; pre- and post-intravesical BCG immunohistochemical study].

At present, the most efficacious and used immunostimulant agent in the superficial bladder cancer immunotherapy field, is the BCG, even if its mechanism of action is still partly unknown. The therapeutic effects of BCG don't seem to depend exclusively on local immune response, so that according to this assertion, this immunohistochemical study had been conducted on 14 patients affected by superficial bladder cancer (pTa-pT1) which aimed to value both the apoptosis and proliferation indexes and the expression of the genetic product p53 and EGFR before and after the exposition of the vesical mucosa to the BCG. The BCG treatment can reduce the proliferation index of the normal urothelial cells in a statistically significant way whereas it would exclude a cytostatic effect mediate by negative modulation of EGFR from the cytokinins induced by BCG itself. The index of apoptosis of the urothelium does not increase after BCG and decreased expression of p53 associated after the treatment, although statistically not significant, it would seem to bear, the prophylactic efficacy of BCG according to the follow up of the patients included in the study.
