Micro-ultrasound guidance finds prostate cancer at same rate as MRI

This study compared two methods for guiding prostate biopsies: micro-ultrasound and multiparametric magnetic resonance imaging. The researchers looked at data from 3,667 patients using micro-ultrasound and 3,887 patients using MRI. They wanted to know if one method was better at finding clinically significant prostate cancer. The results showed no significant difference in detection rates between the two approaches. The odds ratio was 1.13, with a p-value of 0.07, indicating the difference was not statistically significant. Similarly, the detection of clinically insignificant cancer showed no significant difference between the methods. The odds ratio was 0.89 with a p-value of 0.25. No adverse events or safety concerns were reported in this meta-analysis. Because the study included thousands of patients, the findings are based on a substantial amount of data. The certainty of the results is high given the large sample size and consistent outcomes across both groups. This suggests that micro-ultrasound guidance may be a suitable alternative or complementary approach to MRI guidance for prostate biopsies. Patients and doctors can consider this option when planning diagnostic procedures.
