The role of 3-dimensional mapping biopsy in decision making for treatment of apparent early stage prostate cancer.

Purpose: We determined the impact of a grid based, transperineal 3-dimensional mapping biopsy on decision making for primary management of early stage prostate cancer.

Materials And Methods: We prospectively performed 3-dimensional mapping biopsy on 180 consecutive men who presented to our clinic between 2006 and 2009 with early stage, organ confined prostate cancer based on transrectal ultrasound guided 10 to 12-core biopsy, and on 35 with prior negative transrectal ultrasound biopsies.

Results: At presentation median patient age was 60.
