  Purpose

As clinical primary endpoints we assessed whether existed differences in:

  1. PSA recurrence rate stratified according to treatment modalities
  2. EGFR and HER2/neu overexpression rate stratified according to treatment modalities
  3. PSA recurrence rate stratified according to EGFR and HER2/neu overexpression levels.

As secondary clinical endpoints we assessed whether existed differences in:

  1. prostate cancer-specific mortality according to treatment modalities
  2. prostate cancer-specific mortality stratified according to EGFR and HER2/neu overexpression levels.

For this purpose a post treatment PSA-doubling time of less than 3 months found following PSA recurrence was considered as a surrogate endpoint for prostate cancer-specific mortality Pre-clinical endpoints As pre-clinical endpoint we assessed whether exist differences in efficacy rate of Bicalutamide and Gefitinib treatment in primary tumor cultures stratified for high and low EGFR and HER2/Neu expression levels. The evaluation of efficacy rate of these treatments was documented by comparing the differences of drugs IC50 values among the groups stratified for EGFR and HER2/Neu levels.
