Abstract
Objective: To examine the rate of detecting index tumor using transrectal ultrasonography-guided prostate biopsy (TRUS Bx) in patients who underwent radical prostatectomy Design: Retrospective study Setting: Urology Clinic of Tepecik Health Research and Application Center (SUAM) of the University of Health Science Subjects: The study included 418 patients who had TRUS Bx and were diagnosed with prostate cancer and underwent radical prostatectomy between 2007-2014. Intervention: Patients’ data such as age, prostate volume before TRUS Bx, positive cores in TRUS Bx, the highest percentage of cancer in one core, index tumor volume in the specimen and D’Amico risk class were recorded, as well as the detectability of index tumor by TRUS Bx. Main outcome measures: The rate of detecting index tumor with TRUS Bx was examined. Results: Mean age of the included 418 patients was 63.25±6.10 years, prostate volume was 48.50±23.27 cc and preoperative prostate specific antigen value was 11.08±8.27. Index tumor was detected in 260 (62.2%) patients by biopsy but could not be detected in 158 (37.8%) patients. Conclusion: It was thought that biopsy method could be used in detection of index tumor, especially in patients with low risk or large tumor volume.
