Abstract: | We assessed the difference in the detection rate of prostate cancer, specifically clinically significant prostate cancer, using targeted biopsy (TB), systematic biopsy (SB), and the combination of these 2 (CB) in biopsy-naive men with positive multiparameter magnetic resonance imaging results. We performed a literature review in September 2018 using PubMed and the Web of Science. Relevant studies acquired from specific articles’ references were also reviewed. Only those studies that had provided the detection rate of TB, SB, and CB in biopsy-naive men with positive multiparameter magnetic resonance imaging findings were included for a total of 11 studies with 2099 patients. The combined strategy was better than TB or SB alone, with an odds ratio (OR) of 1.47 (95% confidence interval [CI], 1.30-1.67; P < .001) and 1.45 (95% CI, 1.28-1.65; P < .001), respectively, in the overall detection rate. Also, TB was not better than SB, with an OR of 0.99 (95% CI, 0.87-1.12; P = .825). For the clinically significant prostate cancer detection rate, CB was still better than TB or SB alone, with an OR of 1.25 (95% CI, 1.11-1.42; P < .001) and an OR of 1.23 (95% CI, 1.08-1.40; P = .002), respectively. Again, TB was not better than SB, with an OR of 0.98 (95% CI, 0.86-1.12; P = .768). In conclusion, CB resulted in a better detection rate than TB or SB alone for both the overall prostate cancer detection rate and the clinically significant prostate cancer detection rate. |
