Location and Pathological Characteristics of Cancers in Radical Prostatectomy Specimens Identified by Transperineal Biopsy Compared to Transrectal Biopsy
The Journal of Urology, 08/17/2012
Hossack T et al. – Overall transrectal and transperineal biopsy identify cancers that are similar in size, stage and significance. However, transperineal biopsy detected proportionally more anterior tumors, and identified them at a smaller size and stage compared to transrectal biopsy. Identifying anterior tumors early is important because the positive surgical margin rate for anterior pT3 lesions is significantly higher.
