The Impact of Core Length on Prostate Cancer Diagnosis during a Standard 14-Core Prostate Biopsy Scheme

Abstract

The cancer detection rates in cores may be increased by core length in PCa patients during a TRUSBx. Our results suggest a core length of greater than 11.8 mm as a cut-off for quality warranty.

Prostate Cancer Diagnosis: Biopsy Approaches

“…Biopsy core length improves quality of tissue and sensitivity for diagnosis with suggestion that 12 mm is the minimum length required, whereas needle diameter does not appear to improve prostate cancer detection rates (66)(67)(68)(69)(70)(71). Most biopsy guns are designed to obtain standard core lengths of 20 mm, some devices have been designed to take longer cores, though longer needles have an increased risk of deflection and therefore potentially lower sampling accuracy (72,73).…”
