Probability of finding T1a and T1b (Incidental) prostate cancer during TURP has decreased in the PSA era

Abstract

The purpose of this study is to assess the likelihood of detecting stage T1a and T1b cancer in transurethral prostatectomy specimens during the PSA era. Comparison was made of transurethral resection of prostate (TURP) cohorts in the pre-PSA era (1986–1987) and the PSA era (1994–2000), excluding patients with known PCa. A total of 228 men without a known history of prostate cancer underwent TURP during the pre-PSA era time frame and 501 underwent the procedure during the PSA era time frame. Malignancy diagnosed at the time of TURP decreased from 14.9 to 5.2% of patients in the pre-PSA and PSA eras, respectively. Stage T1a decreased from 4.4 to 2.4% and Stage T1b decreased from 10.5 to 2.8% of patients in the pre-PSA and PSA eras, respectively (P<0.001, Fisher's exact test). Prostate cancer newly identified during TURP has decreased significantly in the era of PSA screening in our study population, with the most significant drop being in clinically significant stage T1b. The decrease in TURP rates reduces the overall incidence of T1a/b cancer but cannot explain the lower risk of detecting previously unsuspected cancer at the time of any given TURP. Identification of many men with occult prostate cancer before TURP through screening and early detection is the most likely cause of this finding. These data suggest that men considering surgical or medical management of benign prostatic hyperplasia may be informed that it should be infrequent that men properly evaluated for prostate cancer will harbor clinically significant undetected malignancy.
