Abstract
Purpose: Transperineal template prostate mapping biopsy is an increasingly used method of procuring tissue from men with suspected prostate cancer. We report patient related outcome measures and adverse events in men in the PICTURE trial (ClinicalTrials.gov NCT01492270) who underwent this diagnostic test.
Materials and methods: A total of 249 men underwent multiparametric magnetic resonance imaging followed by transperineal template prostate mapping biopsy as a validation study. Functional outcomes before and after transperineal template prostate mapping were prospectively collected and recorded with questionnaires, including the I-PSS (International Prostate Symptom Score), the I-PSS-QoL (Quality of Life), the IIEF-15 (International Index of Erectile Function-15) and the EPIC (Expanded Prostate Cancer Index Composite) urinary function.
Results: Mean age was 62 years, median prostate specific antigen was 6.8 ng/ml and median gland size was 37 ml. At transperineal template prostate mapping biopsy a median of 49 cores (IQR 40-55) were taken. Mean time to complete the post-procedure patient related outcome measure questionnaires was 46 days. Adverse events included post-procedure acute urinary retention in 24% of patients, rectal pain in 26% and perineal pain in 41%. Transperineal template prostate mapping biopsy resulted in a statistically significant increase in scores on the I-PSS from 10.9 to 11.8 (p = 0.024) and the I-PSS-QoL from 1.57 to 1.76 (p = 0.03). The IIEF-15 erectile function score decreased by 23.2% from 47.7 to 38.7 (p <0.001). Significant deterioration was noted in all 5 of IIEF-15 functional domains, including erectile and orgasmic function, sexual desire, and intercourse and overall satisfaction (p <0.001). EPIC urinary scores showed no overall change from baseline.
Conclusions: Transperineal template prostate mapping biopsy causes a high urinary retention rate and a detrimental impact on genitourinary functional outcomes, including deterioration in urinary flow and sexual function. Our findings can be used to ensure adequate counseling about transperineal template prostate mapping biopsies. The results point to a need for strategies such as multiparametric magnetic resonance imaging and targeted biopsies to minimize the harms of transperineal template prostate mapping biopsy.
