Abstract

Purpose: We assessed the differential expression of survivin and other apoptotic markers in stromal and epithelial compartments of benign prostatic hyperplasia (BPH) and normal prostate tissue. Materials and Methods: Immunohistochemical staining for survivin, and transforming growth factor-β1 and its receptors was done in normal prostate and BPH areas from 114 consecutive patients who underwent radical prostatectomy. Moreover, staining for survivin, Bcl-2, Bax, caspase-3 and Ki-67 was performed in prostate specimens from 23 consecutive patients who underwent open prostatectomy and 4 young patients who underwent cystoprostatectomy and had a normal prostate. Results: Survivin and Bcl-2 expression increased incrementally from normal prostate to epithelial BPH to stromal BPH. Caspase-3 expression was higher in BPH epithelium than in BPH stroma, which in turn was higher than that in normal prostate. Ki-67 was significantly over expressed in BPH stroma and epithelium. Survivin expression in BPH tissue correlated with International Prostate Symptom Score, quality of life, post-void residual urine volume, maximum urine flow rate and transforming growth factor-β1 expression. Conclusions: Survivin is over expressed in BPH and it correlates with BPH parameters. Increases in proliferation and inhibition of apoptosis have a role in BPH.
