Positive Posterior Margin of Needle Biopsy Cores Is an Independent Predictor for Extracapsular Extension in Retropubic Radical Prostatectomy

This suggests that the posterior margin in biopsy specimens is a more reliable and clinically useful parameter when making decisions concerning the choice of treatments.
