This study attempted to determine whether the Gleason score (GS) assigned at a comprehensive cancer center better predicts risk of biochemical failure (BF) after prostate radiotherapy compared with the GS of the referring institution (RI). Between 1994 and 2007, 1649 men received radiotherapy for prostate cancer at Fox Chase Cancer Center (FCCC). The Cox proportional hazard regression was used for inferences about the relationship of time to BF and GS. Harrell’s C-index (HCI) was used to assess concordance in the Cox regression between predicted and observed events. The discordance rate was 26% for any change in either major or minor Gleason pattern. In the RI GS 2 through 6 group, 79 (8%) patients were upgraded to GS 7. Twenty percent of patients with RI GS 7 were downgraded and 2% were upgraded. In the RI GS 8 through 9 group, 58% were downgraded to GS 6 (12%) or GS 7 (88%). The FCCC GS altered the NCCN risk group assignment in 144 men (9%): 92 (64%) men to lower risk and 52 (36%) to higher risk. FCCC GS was a stronger predictor of BF; the hazard ratios for GS 2 through 6 (ref), 3+4, 4+3, and 8 through 9 were 1.00 (ref), 1.82, 4.14, and 2.92, respectively. In contrast, the hazard ratios for the RI GS were 1.00 (ref), 1.53, 2.44, and 1.76, respectively. FCCC GS (HCI=0.76) had improved performance compared with RI GS (HCI=0.74). Changes in GS were common and the GS assigned by a comprehensive cancer center provided better BF risk stratification and prognostication for patients. Changes in GS may impact treatment recommendations in 9% to 26% of patients.

This selection from the NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) for Bladder Cancer focuses on systemic therapy for muscle-invasive urothelial bladder cancer, as substantial revisions were made in the 2017 updates, such as new recommendations for nivolumab, pembrolizumab, atezolizumab, durvalumab, and avelumab. The complete version of the NCCN Guidelines for Bladder Cancer addresses additional aspects of the management of bladder cancer, including non–muscle-invasive urothelial bladder cancer and nonurothelial histologies, as well as staging, evaluation, and follow-up.

The NCCN Clinical Practice Guidelines in Oncology for Bladder Cancer provide recommendations for the diagnosis, evaluation, treatment, and follow-up of patients with bladder cancer. These NCCN Guidelines Insights discuss important updates to the 2018 version of the guidelines, including implications of the 8th edition of the AJCC Cancer Staging Manual on treatment of muscle-invasive bladder cancer and incorporating newly approved immune checkpoint inhibitor therapies into treatment options for patients with locally advanced or metastatic disease.

These NCCN Guidelines Insights discuss the major recent updates to the NCCN Guidelines for Bladder Cancer based on the review of the evidence in conjunction with the expert opinion of the panel. Recent updates include (1) refining the recommendation of intravesical bacillus Calmette-Guérin, (2) strengthening the recommendations for perioperative systemic chemotherapy, and (3) incorporating immunotherapy into second-line therapy for locally advanced or metastatic disease. These NCCN Guidelines Insights further discuss factors that affect integration of these recommendations into clinical practice.
