Optimization of Risk Stratification in Localized Prostate Cancer

Abstract

The Oncology Grand Rounds series is designed to place original reports published in the Journal into clinical context. A case presentation is followed by a description of diagnostic and management challenges, a review of the relevant literature, and a summary of the authors' suggested management approaches. The goal of this series is to help readers better understand how to apply the results of key studies, including those published in Journal of Clinical Oncology, to patients seen in their own clinical practice. A 67-year-old retired engineering professor was found to have a prostate-specific antigen (PSA) level of 11 ng/mL on a screening test at his annual physical examination. A digital rectal examination revealed a nodule on the right side. He underwent a transrectal ultrasound-guided prostate biopsy that was notable for prostate adenocarcinoma, Gleason 3 + 4 = 7 (Gleason grade group 2; 30% Gleason 4 component) involving two cores (60% and 20% core involvement). A bone scan and pelvic computed tomography scan were negative for evidence of metastatic disease. (Should he undergo prostate magnetic resonance imaging? That seems rather common these days.) He was diagnosed with cT2b intermediate-risk localized prostate cancer (PCa) by National Comprehensive Cancer Network (NCCN) risk group and was seen in the multidisciplinary clinic to discuss management options (Table 1).
