Study Type - Diagnostic (exploratory cohort) Level of Evidence 2b What's known on the subject? and What does the study add? Men with persistent suspicion for prostate cancer after previous negative standard transrectal biopsy series are offered saturation biopsy either transrectally or transperineally to increase cancer detection rate. A high-risk group of men with at least two previous negative transrectal biopsies underwent transperineal template-guided saturation biopsy. Prostate cancer was detected in 26%, predominantly in the anterior zones. PSA velocity or doubling time were the most powerful factors to predict cancer. OBJECTIVE: • To evaluate the detection rate and the regional location of prostate cancer in men undergoing transperineal template-guided saturation biopsy (TTSB). PATIENTS AND METHODS: • In all, 92 consecutive men with at least two previous negative transrectal biopsy series who underwent a multiple-core prostate TTSB at our centre were included in the study. • Univariable and multivariable logistic regression analyses were used to address the relationship between parameters before TTSB and prostate cancer-detection rate. • Covariates consisted of age at biopsy, free and total prostate-specific antigen (PSA), prostate volume, digital rectal examination findings, histological findings on previous biopsy, PSA velocity (PSAV), PSA-doubling time (PSADT) and the number of previous negative biopsy sets. RESULTS: • Prostate cancer was diagnosed in 26% of the men. • A median of 30 cores was taken by TTSB. • Adenocarcinoma in >2 cores was detected in 58.5% and Gleason score ≥7 was detected in 46% of the diagnosed men. • Most of the tumours (83.3%) were found in the anterior zones of the gland, with a significantly higher number of positive cores vs the posterior zones (mean 4.9 vs 1.5, P= 0.015). • PSADT and PSAV were the only independent predictors of prostate cancer detection at multivariate analyses with odds ratios of 0.71 (P= 0.014) and 1.58 (P= 0.025), respectively. CONCLUSIONS: • TTSB has a high prostate cancer-detection rate, especially in the anterior zones. • Men after at least two previous negative transrectal biopsy series and persistent suspicion of prostate cancer, as evidenced by rapid PSA dynamics, should be offered TTSB. |
