OPTIMAL COMBINATIONS OF SYSTEMATIC SEXTANT AND LATERALLY DIRECTED BIOPSIES FOR THE DETECTION OF PROSTATE CANCER

Abstract

The standard sextant protocol failed to detect a large proportion of cancers located laterally in the peripheral zone. A 10 core biopsy regimen that combined laterally directed cores at the base, mid gland and apex of the prostate with mid lobar biopsy cores at the base and apex maximizes the sensitivity of transrectal ultrasound guided systematic biopsy.
