Role of transition zone sampling by TURP in patients with raised PSA and multiple negative transrectal ultrasound-guided prostatic biopsies.
The purpose of the study was to determine the role of transurethral resection of the prostate (TURP) to detect prostate cancer in patients with consistently negative transrectal ultrasound-guided biopsies of the prostate. We retrospectively identified and analysed the patients who also had at least two sets of transrectal ultrasound guided sextant prostate biopsies before their TURP during the period between 1998 and 2002. A total of 14 such patients were identified and the outcome of TURP was analysed. Three patients were found to have cancer in the resected specimen (3/14 = 21%). All three cancers were significant (Gleason scores between 6 and 8) and required further treatment. In patients who have rising levels of prostate-specific antigen and who have had multiple negative peripheral zone biopsies, the presence of biologically important transition zone cancers needs to be considered. This can be detected by transurethral resection of the prostate that samples the transition zone of the prostate.
