BIRC5 and prostate adenocarcinoma: In our study, in prostate adenocarcinoma, the survivin expression was higher than BPH and this result is in accordance with the results of Rodríguez-Berriguete et al. (Rodríguez-Berriguete et al. 2010), but the study by Yu et al. (2010) suggests that survivin expression in BPH does not differ significantly from normal prostate tissue.
