Enhancing Prostate Cancer Detection Accuracy in Magnetic Resonance Imaging–targeted Prostate Biopsy: Optimizing the Number of Cores Taken

In this report, we found that increasing the number of biopsy cores up to ≥5 improves the detection rates of significant prostate cancer significantly to around 90%. Although inclusion of nearby and systematic biopsies enhances detection, increasing the biopsy count may lead to higher risks of complications and indolent tumors. A customized biopsy approach based on multiple variables could be helpful in determining the appropriate number of targeted biopsies on a case-by-case basis.
