Article Synopsis
  • The study investigates the impact of tumor characteristics on the feasibility of endoscopic management (EM) for upper tract urothelial carcinoma (UTUC) by creating a standardized assessment score known as the Upper TRACT Endometry Score.
  • Utilizing expert opinions through a modified Delphi method, the score incorporates factors like tumor radius, architecture, count, and location, validating it with a retrospective database of patients undergoing EM for UTUC.
  • Results indicate a significant correlation between the Upper TRACT Endometry Score and the intensity of procedures required for patients, suggesting its potential for improving patient counseling and standardizing the assessment in future cases.

Background And Objective: The timing of perioperative nephrotoxic chemotherapy for upper tract urothelial carcinoma (UTUC) remains controversial and strongly depends on predicted platinum eligibility after radical nephroureterectomy (RNU). The study objective was to develop and validate a multivariable nomogram to predict estimated glomerular filtration rate (eGFR) following RNU.

Methods: This was a multi-institutional retrospective study of patients with UTUC treated with RNU from 2000 to 2020 at seven high-volume referral centers.

Purpose: The treated natural history of nonmetastatic plasmacytoid variant of bladder cancer (PV-BCa) is poorly understood owing to its rarity. We sought to examine the disease recurrence and metastasis patterns in this select group of patients in order to identify opportunities for intervention.

Materials And Methods: We conducted a natural language processing algorithm-augmented retrospective chart review of 56 consecutive patients who were treated with curative intent for nonmetastatic PV-BCa at our institution between 1998 and 2018.

Objective: UGN-101 has been approved for the chemoablation of low-grade upper tract urothelial cancer (UTUC) involving the renal pelvis and calyces. Herein is the first reported cohort of patients with ureteral tumors treated with UGN-101.

Patients And Methods: We performed a retrospective review of patients treated with UGN-101 for UTUC at 15 high-volume academic and community centers focusing on outcomes of patients treated for ureteral disease.

Background: UGN-101 can be used for chemoablation of low-grade upper tract urothelial carcinoma (UTUC). The gel can be administered via a retrograde route through a ureteral catheter or an antegrade route via a nephrostomy tube.

Objective: To report outcomes of UGN-101 by route of administration.

Purpose: Assess the real-world ablative effect of mitomycin reverse thermal gel for low-grade upper tract urothelial carcinoma (UTUC) in patients who undergo biopsy only or partial ablation and evaluate utility of complete ablation prior to UGN-101.

Material And Methods: We retrospectively reviewed low-grade UTUC patients treated with UGN-101 from 15 high-volume centers. Patients were categorized based on initial endoscopic ablation (biopsy only, partial ablation, or complete ablation) and by size of remaining tumor (complete ablation, <1cm, 1-3cm, or >3cm) prior to UGN-101.

Background: Intracavitary UGN-101 is approved for the treatment of low-grade noninvasive upper tract urothelial carcinoma (UTUC). Post-commercialization studies underscore the benefit of UGN-101 administration for patients with imperative indications for whom radical nephroureterectomy (RNU) is not a viable option.

Objective: To describe the use, efficacy, and safety of UGN-101 in patients with UTUC with imperative indications for renal preservation, including high-grade disease.

Purpose: We describe a novel application of the reverse thermal polymer gel of mitomycin C (UGN-101) as adjuvant therapy after complete endoscopic ablation of upper tract urothelial carcinoma.

Materials And Methods: We retrospectively reviewed patients treated with UGN-101 from 15 high-volume centers. Adjuvant therapy was defined as treatment administered following visually complete endoscopic ablation.

Background: UGN-101 is a novel delivery system for intracavitary treatment of upper tract urothelial cancer (UTUC). UGN-101 was approved based on a pivotal trial for small volume residual low-grade UTUC. Our aim was to report our experience with UGN-101 in a more heterogenous and real-world setting.

Purpose: Our goal was to review the history of the adoption of focal therapy for breast and prostate cancer and review common barriers to implementation.

Materials And Methods: A narrative review of the literature was performed of English-language MEDLINE indexed articles of breast-conservation therapy and prostate cancer focal therapy.

Results: The introduction of focal therapy in breast cancer began with pioneering case series, and multiple randomized trials were performed prior to widespread adoption.

Purpose: Renal function dictates sequencing and eligibility for definitive therapy in upper tract urothelial carcinoma. We investigated longitudinal glomerular filtration rate (GFR) changes after neoadjuvant chemotherapy (NAC) and nephroureterectomy (RNU).

Materials And Methods: Patients treated with ≥3 cycles of chemotherapy prior to RNU for UTUC from 2000 to 2019 were included.

Objective: To determine exposure rates to antibiotics prior to radical cystectomy and determine if there is correlation with post-operative infections.

Methods And Materials: 2248 patients were identified in the 2016 SEER-Medicare linkage who underwent radical cystectomy between 2008 and 2014 with complete prescription information. An outpatient prescription for an antibiotic within 30 days prior to cystectomy was considered exposure.

Introduction: While numerous current clinical trials are testing novel salvage therapies (ST) for patients with recurrent nonmuscle invasive bladder cancer (NMIBC) after bacillus Calmette-Guérin (BCG), the natural history of this disease state has been poorly defined to date. Herein, we evaluated oncologic outcomes in patients previously treated with BCG and ST who subsequently underwent radical cystectomy (RC).

Methods: We identified 378 patients with high-grade NMIBC who received at least one complete induction course of BCG (n = 378) with (n = 62) or without (n = 316) additional ST and who then underwent RC between 2000 and 2018.

Introduction: ISUP Grade Group 1 prostate cancer is the lowest histologic grade of prostate cancer with a clinically indolent course. Removal of the term 'cancer' has been proposed and has historical precedent both in urothelial and thyroid carcinoma.

Methods: Evidence-based review identifying arguments for and against Grade Group 1 being referred to as cancer.

Introduction: For marker-negative clinical stage (CS) IIA nonseminomatous germ cell tumor (NSGCT), National Comprehensive Cancer Network and American Urological Association guidelines recommend either retroperitoneal lymph node dissection (RPLND) or induction chemotherapy. The goal is cure with one form of therapy. We evaluated national practice patterns in the management of CSIIA NSGCT and utilization of secondary therapies.

Objective: To describe the step-by-step techniques and modifications for robot-assisted augmentation ileocystoplasty and Mitrofanoff appendicovesicostomy in a pediatric population with updated institutional results.

Introduction: Robot-assisted laparoscopic augmentation ileocystoplasty with Mitrofanoff appendicovesicostomy (RALIMA) protects the upper urinary tract and reestablishes continence in patients with refractory neurogenic bladder. Robotic assistance could provide the benefits of minimally invasive surgery without the challenges of pure laparoscopy.

Importance: Few studies have evaluated the association between a single-nucleotide polymorphism-based genetic risk score (GRS) and patient age at prostate cancer (PCa) diagnosis.

Objectives: To test the association between a GRS and patient age at PCa diagnosis and to compare the performance of a GRS with that of family history (FH) in PCa risk stratification.

Design, Setting, And Participants: A cohort study of 3225 white men was conducted as a secondary analysis of the Reduction by Dutasteride of Prostate Cancer Events (REDUCE) chemoprevention trial, a 4-year, randomized, double-blind, placebo-controlled multicenter study conducted from March 2003 to April 2009 to evaluate the safety and efficacy of dutasteride in reducing PCa events.

Background: Clinically localized renal cell carcinoma is treated primarily with surgery followed by observation or adjuvant sunitinib in selected high-risk patients. The checkpoint inhibitor immunotherapeutic agents nivolumab and ipilimumab have recently shown a survival benefit in the first-line metastatic setting. To date, there have been no reports on the response of localized renal cancer to modern immunotherapy.
