Predictors of Gleason score upgrading in patients with prostate biopsy Gleason score ≤6

Abstract

When obtaining an extended-core biopsy scheme, patients with small prostates (≤40 cc), greater than 1 core positive for cancer, and an increased burden of cancer are associated with increased risk of GS upgrading. Patients with GS ≤6 on biopsy with these pathological parameters should be carefully counselled on treatment decisions.
