Abstract
- <bold>Background: </bold>We evaluated the cancer detection rate of prostate cancer using transperineal template-guided saturation biopsy aimed at sampling one core for each milliliter of prostate volume for patients requiring repeated prostate biopsies.<bold>Methods: </bold>In total, 103 consecutive patients with repeated prostate biopsies were enrolled in this retrospective study. The number of biopsy cores was defined by prostate volume. In principle, one biopsy core covered 1 mL of prostate volume. We used a prostate brachytherapy template with a 5-mm grid and adopted a transperineal needle biopsy.<bold>Results: </bold>The median age, prostate-specific antigen level, and prostate volume were 69 (range, 37-83) years, 9.2 (range, 1.9-107) ng/mL, and 34.7 (range, 18-76.7) mL, respectively. The median number of biopsy cores was 37 (range, 18-75 cores). Fifty-three patients (51.5%) were diagnosed with prostate cancer. The Gleason score was 6, 7, and 8-10 in 24.5, 64.2 and 11.3% patients, respectively. Forty-two patients (79.2%) were diagnosed with clinically significant PCa. Acute urinary retention was detected in 2 patients (1.9%).<bold>Conclusions: </bold>Transperineal template-guided saturation biopsy with one core per milliliter of prostate volume helped achieve a high cancer detection rate and high significant cancer detection rate with acceptable biopsy-associated adverse events.
