Increasing Life Expectancy in Patients with Genitourinary Malignancies: Impact of Treatment Burden on Disease Management and Quality of Life.

Background And Objective: Treatment burden refers to the overall impact of medical treatments on a patient's well-being and daily life. Our objective is to evaluate the impact of treatment burden on quality of life (QoL) in patients with genitourinary (GU) malignancies, highlighting the importance of patient-reported outcomes (PROs) in clinical trials to inform treatment decisions and improve patient care.

Methods: We conducted a narrative review of clinical trials focused on GU malignancy (prostate, bladder, and kidney) between January 2000 and June 2024, analyzing related PROs and findings regarding treatment burden.

Perioperative Complications and Omission of Ureteral Stents During Robot-Assisted Radical Cystectomy With Intracorporeal Ileal Conduit.

Purpose: Ureteral stents are commonly placed intraoperatively during radical cystectomy, although their efficacy in reducing complications is unproven. We compared clinical outcomes among patients undergoing robot-assisted radical cystectomy with intracorporeal ileal conduit (RARC-IC) with or without ureteral stents to determine if omission of ureteral stents affects postoperative complications.

Materials And Methods: All RARC-IC surgeries performed at our institution between November 2017 and June 2023 were reviewed.

Analysis of human neutrophils from nasal polyps by single-cell RNA sequencing reveals roles of neutrophils in chronic rhinosinusitis.

Background: Chronic rhinosinusitis with nasal polyps (CRSwNP) is characterized by type 2 (T2) inflammation. Recent studies, including our own, suggest that neutrophils are also elevated in T2 nasal polyps (NP) and that elevated neutrophils display an activated phenotype. However, the actual roles of neutrophils in NP pathogenesis in T2 CRSwNP are still largely unclear.

Hypofractionated Radiation Therapy (Hypo-RT) for the Treatment of Localized Bladder Cancer.

Background: Various radiotherapeutic regimens are used in the treatment of bladder cancer.

Objective: We aimed to evaluate early toxicity and outcomes associated with hypofractionated radiation therapy (Hypo-RT), 55Gy in 20 fractions.

Material And Methods: We identified 40 patients who received definitive Hypo-RT for localized bladder cancer.

Differential NEUROD1, ASCL1, and POU2F3 Expression Defines Molecular Subsets of Bladder Small Cell/Neuroendocrine Carcinoma With Prognostic Implications.

Small cell carcinomas (SMC) of the lung are now molecularly classified based on the expression of transcriptional regulators (NEUROD1, ASCL1, POU2F3, and YAP1) and DLL3, which has emerged as an investigational therapeutic target. PLCG2 has been shown to identify a distinct subpopulation of lung SMC with stem cell-like and prometastasis features and poor prognosis. We analyzed the expression of these novel neuroendocrine markers and their association with traditional neuroendocrine markers and patient outcomes in a cohort of bladder neuroendocrine carcinoma (NEC) consisting of 103 SMC and 19 large cell NEC (LCNEC) assembled in tissue microarrays.

scRNA-seq profiling of human granulocytes reveals expansion of developmentally flexible neutrophil precursors with mixed neutrophil and eosinophil properties in asthma.

Neutrophils and eosinophils share common hematopoietic precursors and usually diverge into distinct lineages with unique markers before being released from their hematopoietic site, which is the bone marrow (BM). However, previous studies identified an immature Ly6g(+) Il-5Rα(+) neutrophil population in mouse BM, expressing both neutrophil and eosinophil markers suggesting hematopoietic flexibility. Moreover, others have reported neutrophil populations expressing eosinophil-specific cell surface markers in tissues and altered disease states, confusing the field regarding eosinophil origins, function, and classification.

Prevention of allergic reactions during oxaliplatin desensitization through inhibition of Bruton tyrosine kinase.

Background: Acute infusion reactions to oxaliplatin, a chemotherapeutic used to treat gastrointestinal cancers, are observed in about 20% of patients. Rapid drug desensitization (RDD) protocols often allow the continuation of oxaliplatin in patients with no alternative options. Breakthrough symptoms, including anaphylaxis, can still occur during RDD.

Biologic therapy in rare eosinophil-associated disorders: remaining questions and translational research opportunities.

Rare eosinophil-associated disorders (EADs), including hypereosinophilic syndrome, eosinophilic granulomatosis with polyangiitis, and eosinophilic gastrointestinal disorders, are a heterogeneous group of conditions characterized by blood and/or tissue hypereosinophilia and eosinophil-related clinical manifestations. Although the recent availability of biologic therapies that directly and indirectly target eosinophils has the potential to dramatically improve treatment options for all EADs, clinical trials addressing their safety and efficacy in rare EADs have been relatively few. Consequently, patient access to therapy is limited for many biologics, and the establishment of evidence-based treatment guidelines has been extremely difficult.

Controlled adsorption of multiple bioactive proteins enables targeted mast cell nanotherapy.

Protein adsorption onto nanomaterials often results in denaturation and loss of bioactivity. Controlling the adsorption process to maintain the protein structure and function has potential for a range of applications. Here we report that self-assembled poly(propylene sulfone) (PPSU) nanoparticles support the controlled formation of multicomponent enzyme and antibody coatings and maintain their bioactivity.

Multiparametric MRI in Era of Artificial Intelligence for Bladder Cancer Therapies.

This review focuses on the principles, applications, and performance of mpMRI for bladder imaging. Quantitative imaging biomarkers (QIBs) derived from mpMRI are increasingly used in oncological applications, including tumor staging, prognosis, and assessment of treatment response. To standardize mpMRI acquisition and interpretation, an expert panel developed the Vesical Imaging-Reporting and Data System (VI-RADS).

A Quantitative Multiparametric MRI Analysis Platform for Estimation of Robust Imaging Biomarkers in Clinical Oncology.

There is a need to develop user-friendly imaging tools estimating robust quantitative biomarkers (QIBs) from multiparametric (mp)MRI for clinical applications in oncology. Quantitative metrics derived from (mp)MRI can monitor and predict early responses to treatment, often prior to anatomical changes. We have developed a vendor-agnostic, flexible, and user-friendly MATLAB-based toolkit, MRI-Quantitative Analysis and Multiparametric Evaluation Routines ("MRI-QAMPER", current release v3.

Interactions between Siglec-8 and endogenous sialylated cis ligands restrain cell death induction in human eosinophils and mast cells.

Sialic acid-binding immunoglobulin-like lectin (Siglec)-8 is a sialoside-binding receptor expressed by eosinophils and mast cells that exhibits priming status- and cell type-dependent inhibitory activity. On eosinophils that have been primed with IL-5, GM-CSF, or IL-33, antibody ligation of Siglec-8 induces cell death through a pathway involving the β2 integrin-dependent generation of reactive oxygen species (ROS) via NADPH oxidase. In contrast, Siglec-8 engagement on mast cells inhibits cellular activation and mediator release but reportedly does not impact cell viability.

Clinical and Genomic Landscape of FGFR3-Altered Urothelial Carcinoma and Treatment Outcomes with Erdafitinib: A Real-World Experience.

Purpose: Erdafitinib is the only FDA-approved targeted therapy for FGFR2/3-altered metastatic urothelial cancer. We characterized the genetic landscape of FGFR-altered urothelial carcinoma and real-world clinical outcomes with erdafitinib, including on-treatment genomic evolution.

Experimental Design: Prospectively collected clinical data were integrated with institutional genomic data to define the landscape of FGFR2/3-altered urothelial carcinoma.

Feasibility and tissue concordance of genomic sequencing of urinary cytology in upper tract urothelial carcinoma.

Background: There is limited ability to accurately diagnose and clinically stage patients with upper tract urothelial carcinoma (UTUC). The most easily available and widely used urinary biomarker is urine cytology, which evaluates cellular material yet lacks sensitivity. We sought to assess the feasibility of performing next-generation sequencing (NGS) on urine cytology specimens from patients with UTUC and evaluate the genomic concordance with tissue from primary tumor.

IL-15 synergizes with CD40 agonist antibodies to induce durable immunity against bladder cancer.

CD40 is a central costimulatory receptor implicated in productive antitumor immune responses across multiple cancers, including bladder cancer. Despite strong preclinical rationale, systemic administration of therapeutic agonistic antibodies targeting the CD40 pathway has demonstrated dose-limiting toxicities with minimal clinical activity, emphasizing an important need for optimized CD40-targeted approaches, including rational combination therapy strategies. Here, we describe a role for the endogenous IL-15 pathway in contributing to the therapeutic activity of CD40 agonism in orthotopic bladder tumors, with upregulation of transpresented IL-15/IL-15Rα surface complexes, particularly by cross-presenting conventional type 1 DCs (Dendritic Cells), and associated enrichment of activated CD8 T cells.

A Cell-Free Protein Synthesis Platform to Produce a Clinically Relevant Allergen Panel.

Radical Cystectomy in the Treatment of Invasive Bladder Cancer: Long-Term Results in 1,054 Patients.

Purpose: To evaluate our long-term experience with patients treated uniformly with radical cystectomy and pelvic lymph node dissection for invasive bladder cancer and to describe the association of the primary bladder tumor stage and regional lymph node status with clinical outcomes.

Patients And Methods: All patients undergoing radical cystectomy with bilateral pelvic iliac lymphadenectomy, with the intent to cure, for transitional-cell carcinoma of the bladder between July 1971 and December 1997, with or without adjuvant radiation or chemotherapy, were evaluated. The clinical course, pathologic characteristics, and long-term clinical outcomes were evaluated in this group of patients.

Siglecs as potential targets of therapy in human mast cell- and/or eosinophil-associated diseases.

Siglecs (sialic acid-binding immunoglobulin-like lectins) are a family of vertebrate glycan-binding cell-surface proteins. The majority mediate cellular inhibitory activity once engaged by specific ligands or ligand-mimicking molecules. As a result, Siglec engagement is now of interest as a strategy to therapeutically dampen unwanted cellular responses.
