ABSTRACT
OBJECTIVE: To describe the management and outcomes of patients with Ta predominantly low-grade urothelial carcinoma with focal high-grade features (FHG) (<5%), compared to those with Ta low grade (LG) and Ta high grade (HG). METHODS: Retrospective review of all patients who underwent transurethral resection of bladder tumor between 2005 and 2023. Patients with Ta disease were identified and categorized into LG, FHG, and HG. Kaplan Meier method was used to depict high-grade recurrence, T-stage progression, and radical cystectomy-free survival. RESULTS: Four hundred forty-nine patients with Ta disease were identified (LG 48%, FHG 12%, and HG 40%). Patients with FHG (32%) had a second-look transurethral resection of bladder tumor more frequently compared to LG (7%) and HG (29%) (P <.01). They received intravesical therapy more frequently compared to LG (36% vs 20%) but lower than HG (55%) (P <.01). They received radical cystectomy less frequently (7% compared to 20% for HG and 11% for LG, P = .01). HG recurrence-free survival at 1, 3, and 5years was HG (68%, 52%, and 43%), FHG (74%, 53%, and 49%), and LG (87%, 79%, and 73%) (log-rank P <.01). T progression-free survival at 1, 3, and 5years was HG (84%, 77%, and 70%), FHG (92%, 82%, and 82%), and LG (94%, 89%, and 85%) (log-rank P = .02). Cystectomy-free survival at 1, 3, and 5years was HG (92%, 84%, and 80%), FHG (96%, 94%, and 94%), and LG (99%, 95%, and 92%) (log-rank P <.01). CONCLUSION: Patients with Ta FHG seem to behave more like Ta HG disease in terms of high-grade recurrences, but they are less likely to experience T-stage progression and convert to cystectomy.
ABSTRACT
INTRODUCTION: We sought to investigate the impact of National Comprehensive Cancer Network (NCCN)-compliant multidisciplinary conference on the uptake of active surveillance (AS) among eligible patients with prostate cancer. METHODS: Retrospective review of our AS database was performed. Patients who are eligible for AS who sought a second opinion at a comprehensive cancer center (2010-2021) were presented to the multidisciplinary Localized Prostate Cancer Conference (LPCC) that includes urologists, radiation oncologists, pathologists, and patient advocates. Cochrane Armitage test was used to examine trends over time. Multivariable regression models were fit to evaluate variables associated with the receipt of AS. RESULTS: Seven hundred twelve patients were identified (19% NCCN very low risk, 32% low risk, and 49% intermediate favorable risk). 43% were recommended AS as the preferred option by the community compared to 68% by LPCC, and 65% elected AS. Recommending AS significantly increased between 2010 and 2021 by the community (from 26% to 57%) and by LPCC (from 52% to 82%), while the proportion of men who received AS increased from 47% to 80% during the same period (P < 0.0001 for all). More recent LPCC era 2017 to 2021 (OR 12.31, 95% CI, 5.60-27.03, P < 0.0001), African American race (OR 0.42, 95% CI, 0.18-0.96, Pâ¯=â¯0.04), positive cores at biopsy (OR 0.96, 95% CI, 0.94-0.97, P < 0.0001), age (OR 1.14, 95% CI, 1.10-1.18, P < 0.0001), NCCN low risk (OR 0.25, 95% CI, 0.08-0.81, Pâ¯=â¯0.02) and NCCN intermediate favorable risk (OR 0.03, 95% CI, 0.01-0.09, P < 0.0001) were associated with receipt of AS. CONCLUSION: AS recommendation increased significantly over time by community urologists and to a higher extent by NCCN-compliant multidisciplinary conference. The Uptake of AS significantly increased within the same period. More recent LPCC era 2017 to 2021, African American race, the proportion of positive cores at biopsy, age, and NCCN risk were the main determinants of receipt of AS.
