Tumor characteristics in immunosuppressed and renal dysfunction populations.

Purpose: Renal transplantation and end-stage renal disease are increasingly common. Renal dysfunction and immunosuppression are two risk factors in the development of renal cell carcinoma. Carcinomas in these patients are thought to be more indolent, however data are limited and mixed.

Neoadjuvant androgen deprivation therapy with or without Fc-enhanced non-fucosylated anti-CTLA-4 (BMS-986218) in high risk localized prostate cancer: a randomized phase 1 trial.

Men with high-risk localized prostate cancer exhibit high rates of post-surgical recurrence. In these patients, androgen deprivation therapy (ADT) is immunomodulatory, however increased infiltration of regulatory T cells (Tregs) may limit the antitumor immune effects of ADT. We designed a neoadjuvant clinical trial to test whether BMS-986218 - a next-generation non-fucosylated anti-CTLA-4 antibody engineered for enhanced antibody-dependent cellular cytotoxicity or phagocytosis (ADCC/P) - depletes intratumoral Tregs and augments the response to ADT.

Rosiglitazone and trametinib exhibit potent anti-tumor activity in a mouse model of muscle invasive bladder cancer.

Muscle invasive bladder cancers (BCs) can be divided into 2 major subgroups-basal/squamous (BASQ) tumors and luminal tumors. Since Pparg has low or undetectable expression in BASQ tumors, we tested the effects of rosiglitazone, Pparg agonist, in a mouse model of BASQ BC. We find that rosiglitazone reduces proliferation while treatment with rosiglitazone plus trametinib, a MEK inhibitor, induces apoptosis and reduces tumor volume by 91% after 1 month.

The Impact of American Board of Urology Certification on Postoperative Outcomes for Patients in New York State.

Introduction: Our goal was to determine if board certification status was associated with improved postoperative outcomes for certain urologic oncology operations.

Methods: We performed a retrospective cohort study of patients aged 65 and over having radical prostatectomy (RP), radical cystectomy (RC), and radical or partial nephrectomy (RPN) by surgeons with New York State licenses from 2015 to 2021 using the Medicare limited dataset. Our primary exposure was surgeon American Board of Urology certification determined by the New York State Physician Profile.

Incidence and management of prostatic urethra recurrence in a cohort of 21 patients who received BCG induction for non-muscle invasive bladder cancer.

Purpose: To describe the incidence and management of patients who develop a prostatic urethral (PU) urothelial carcinoma recurrence after Bacillus Calmette-Guerin (BCG) induction for non-muscle invasive bladder cancer (NMIBC).

Materials And Methods: We performed a retrospective cohort study of all patients who received BCG induction at our institution from 1996 to 2021 (N = 642) for NMIBC. All patients with pathologically confirmed PU involvement following BCG induction with no known PU involvement pre-BCG were included.
