Comprehensive tumor-immune profiling reveals mediators of paradoxical immune sensitivity in sarcomatoid renal cell carcinoma.

Renal cell carcinoma with sarcomatoid features (sRCC) is a highly aggressive tumor type yet preferentially responds to immune checkpoint blockade (ICB). To better understand microenvironmental mediators of this paradoxical immune sensitivity, we performed single-cell analyses of human sRCC tumors compared against clear cell RCC (ccRCC), with validation spatially and in bulk transcriptomic datasets totaling over 3,000 RCC tumors. We describe a robust immune network in sRCC using these orthogonal approaches: tumor-infiltrating T cells in sRCC are more activated, and subsequently exhausted, while being enriched for CXCL13 expression.

Comparative Genomic Characterization of Small Cell Carcinoma of the Bladder Compared With Urothelial Carcinoma and Small Cell Lung Carcinoma.

Purpose: Small cell bladder cancer (SCBC) is a rare histologic variant of bladder cancer with an aggressive disease course and poor outcomes. Given its uncommon nature, there is a paucity of high-quality data characterizing genomic drivers of this disease, and most patients are treated with approaches mirroring small cell lung cancer (SCLC). Leveraging the Tempus Lens deidentified clinically annotated genomic data set, we sought to evaluate the mutational landscape of SCBC relative to urothelial carcinoma (UC) and SCLC.

Eligibility Criteria in Advanced Urothelial Cancer Clinical Trials: An Assessment of Modernization and Inclusion.

Introduction: In a joint statement, Friends of Cancer Research and the American Society of Clinical Oncology affirmed the need for broadening clinical trial eligibility criteria to expand patient access to investigational treatments and enroll cohorts more representative of the general population. Our study aimed to characterize and analyze the prevalence of overly exclusionary eligibility criteria in contemporary clinical trials involving patients with locally advanced and metastatic urothelial cancer.

Methods: Utilizing MeSH query terms "(metastatic OR advanced OR stage IV OR unresectable) AND (bladder cancer OR upper tract urothelial carcinoma OR upper tract urothelial cancer)" in ClinicalTrials.

Successful Diagnosis of a SMARCA4-Deficient Undifferentiated Tumor via Endobronchial Ultrasound-Guided Fine Needle Aspiration and Endobronchial Biopsies.

As treatment options have advanced, the significance of accurate diagnosis has increased, enabling targeted and more personalized therapeutic treatments.

Cabozantinib and nivolumab with or without live bacterial supplementation in metastatic renal cell carcinoma: a randomized phase 1 trial.

Supplementation with CBM588, a bifidogenic live bacterial product, has been associated with improved clinical outcomes in persons with metastatic renal cell carcinoma (mRCC) receiving nivolumab and ipilimumab. However, its effect on those receiving tyrosine kinase inhibitor-based combinations is unknown. In this open-label, randomized, investigator-initiated, phase 1 study, 30 participants with locally advanced or mRCC with histological confirmation of clear cell, papillary or sarcomatoid component were randomized in a 2:1 fashion to receive cabozantinib (an inhibitor of vascular endothelial growth factor receptor, MET and AXL) and nivolumab (anti-programmed cell death protein 1) with or without CBM588 as first-line treatment.

We analyzed data for patients with or without BrM using the International Metastatic Renal Cell Carcinoma Database Consortium (IMDC). A total of 389/4799 patients (8.

Targeting STAT3 in tumor-associated antigen-presenting cells as a strategy for kidney and bladder cancer immunotherapy.

Introduction: Immune checkpoint blockade (ICB) improved clinical outcomes in renal and bladder cancer patients, but the response rates remain limited especially in metastatic disease. While STAT3 transcription factor is well-known master regulator of tumor immune evasion, little is known about the role of STAT3 in the resistance of renal or bladder cancers to immunotherapy.

Methods: To better understand immune alterations associated with ICB resistance, we assessed blood biomarkers in renal cancer patients classified as responders or non-responders to first line nivolumab/ipilimumab immunotherapy.

Racial and ethnic differences in perceptions of germline or somatic DNA sequencing among patients with advanced prostate, urothelial, or kidney cancer.

We sought to determine racial and ethnic differences in perceptions (quality of communication, expectations, and concerns) of germline or somatic DNA sequencing (genomic profiling). Patients with prostate, urothelial, or kidney cancer were surveyed using a questionnaire that assessed previous experience, beliefs, expectations, and concerns regarding genomic profiling. Descriptive statistics and chi-square tests were used to identify factors associated with patients' perceptions of genomic profiling.

Assessment of eligibility criteria in renal cell carcinoma trials evaluating systemic therapy.

Objectives: To characterise the restrictiveness of eligibility criteria in contemporary renal cell carcinoma (RCC) trials, using recommendations from the American Society of Clinical Oncology (ASCO)-Friends of Cancer Research (FCR) initiative.

Methods: vPhase I-III trials assessing systemic therapies in patients with RCC starting between 30 June 2012 and 30 June 2022 were identified.
