We performed a clinical trial in non-muscle invasive urothelial cancer (NMIUC) patients randomized (2:1) to the epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor erlotinib or placebo (either orally once weekly x 3 doses prior to scheduled surgery) to assess for a difference in EGFR phosphorylation in tumor adjacent normal urothelium <24 hours post-study dose and tolerance of weekly erlotinib. Thirty-seven volunteers (6 female/31 male, mean age 70, 35 white/2 non-white) with confirmed or suspected NMIUC were enrolled into either erlotinib (n=24; 900 mg-13, 600 mg-11) or placebo (n=13). Immunohistochemical assessment of phosphorylated and total EGFR in adjacent normal urothelium (20 erlotinib; 9 placebo) or tumor (21 erlotinib and 11 placebo subjects) at study end observed no significant difference between those receiving erlotinib or placebo.

A recent phase 3 trial of intravesical nadofaragene firadenovec reported a promising complete response rate for patients with bacillus Calmette-Guérin-unresponsive non-muscle-invasive bladder cancer. This study examined the ability of antiadenovirus antibody levels to predict the durability of therapeutic response to nadofaragene firadenovec. A standardized and validated quantitative assay was used to prospectively assess baseline and post-treatment serum antibody levels among 91 patients from the phase 3 trial, of whom 47 (52%) were high-grade recurrence free at 12 mo (responders).

Objective: To examine the historical trends and factors underlying the current state of racial/ethnic representation within the urology workforce at each stage of the educational pipeline.

Methods: Using data from the US Census Bureau and the Association of American Medical Colleges, trends in racial/ethnic distribution for 2007-2008 to 2019-2020 were tracked in the educational pipeline for academic urologists. This pipeline was defined as progressively diminishing cohorts, starting with the US population, leading to medical school application, acceptance, and graduation, through to urology residency application, matching, and graduation, and ending with urology faculty appointment.

This article offers a framework for critically examining the structures, policies, norms, practices, and values that shape the Urology Match as a foundation for interventions to improve diversity, equity, inclusion, and justice in the workforce. Points of leverage for transformational change in the urology workforce diversification include modifying the structure of the urology application process, optimizing reviewer factors, addressing Under-Represented in Medicine applicant experience, providing resources to applicants, and evaluating selection criteria. To achieve an inclusive diverse urology workforce, we must change policy and practice, expand what we include in the norm, which will translate into increased value ascribed to a more varied cohort of applicants, leading to the establishment of structures that accommodate true diversity.

Background: Bacillus Calmette-Guérin (BCG) is currently the most clinically effective intravesical treatment for non-muscle-invasive bladder cancer (NMIBC), particularly for patients with high-risk NMIBC such as those with carcinoma in situ. BCG treatments could be optimized to improve patient safety and conserve supply by predicting BCG efficacy based on tumor characteristics or clinicopathological criteria.

Objective: The aim of this study is to assess the ability of specific clinicopathological criteria to predict tumor recurrence in patients with NMIBC who received BCG therapy along various treatment timelines.
