Aims: Xpert Bladder Cancer Monitor is a urinary marker based on the evaluation of five target mRNAs overexpressed in patients with bladder cancer (BC). The aim of our study is to update our results regarding the diagnostic accuracy of the Xpert Bladder Cancer Monitor test in the follow-up of patients with non-muscle invasive bladder cancer (NMIBC).
Methods: We conducted a prospective study on 1015 samples of 416 patients (mean age 72.2 ± 10.3 years) under follow-up for NMIBC. Patients underwent voided urinary cytology, the Xpert Bladder Cancer Monitor test and cystoscopy and, if positive, a transurethral resection of the bladder. Xpert Bladder Cancer Monitor was reported as negative or positive: cut-off total Linear Discriminant Analysis (LDA) = 0.5.
Results: We identified 168 recurrent tumours: 126 (75%) were low-grade (LG) and 42 (25%) high-grade (HG). Overall sensitivity was 17.9% for cytology, 52.4% for Xpert Bladder Cancer Monitor and 54.2% for the two tests combined. The sensitivity of cytology increased from 6.3% in LG to 52.4% in HG tumours whereas Xpert Bladder Cancer Monitor showed a sensitivity ranging from 42.9% in LG to 80.9% in HG tumours. Combined cytology and Xpert Bladder Cancer Monitor yielded an overall sensitivity of 45.2% for LG and 80.9% for HG tumours. Overall specificity was 98.5% for cytology and 78.4% for Xpert Bladder Cancer Monitor and 78.2% for the two tests combined. The area under the curve (AUC) for Xpert Bladder Cancer Monitor was 0.71; stratifying the patients according to the European Association of Urology risk groups, the AUC was 0.69, 0.67 and 0.85 for low, intermediate and high risk, respectively ( = 0.0003).
Conclusion: Our data confirm a significantly higher sensitivity of Xpert Bladder Cancer Monitor than for cytology in a larger patient cohort. The test performed very well in terms of specificity but could not reach the high value of cytology. Along with voided urinary cytology the test could allow to reduce cystoscopies in follow-up patients, reducing discomfort to the patients and costs.

Immune checkpoint therapy has demonstrated significant potential in the treatment of various solid tumors. Among these, tumor-induced immunosuppression mediated by programmed cell death protein 1 (PD-1) represents a critical checkpoint. PD-1/programmed death-ligand 1 (PD-L1) inhibitors have been proven to exhibit substantial efficacy in solid tumors such as melanoma and bladder cancer.

A 71-year-old black male with a history of hypertension, dyslipidemia, type 2 diabetes, history of bladder cancer status-post resection now in remission, history of multiple transient ischemic attacks, and coronary artery disease (CAD) presented with non-exertional substernal chest pain radiating to the left arm, accompanied by shortness of breath and nausea. Initial evaluation revealed elevated troponins and nonspecific electrocardiogram changes, consistent with non-ST elevation myocardial infarction. Coronary angiography demonstrated severe multivessel disease, including critical left main stenosis.

Low-grade non-muscle invasive bladder cancer is a specific category of bladder cancer with a favourable prognosis; however, its management presents several challenges. The risk of stage progression is very low, but approximately half of patients will experience recurrence within the first 5 years after diagnosis. This high propensity for recurrence, coupled with the threat of progression, mandates ongoing surveillance.

With the approval of the antibody-drug conjugate enfortumab vedotin (EV), NECTIN4 has emerged as a bona fide therapeutic target in urothelial carcinoma (UC). Here, we report the development of a NECTIN4-directed chimeric antigen receptor (CAR) T cell, which exhibits reactivity across cells expressing a range of endogenous NECTIN4, with enhanced activity in high expressors. We demonstrate that the PPARγ pathway, critical for luminal differentiation, transcriptionally controls NECTIN4, and that the PPARγ agonist rosiglitazone primes and augments NECTIN4 expression, thereby increasing sensitivity to NECTIN4-CAR T cell-mediated killing.

Background: Understanding the mutational landscape is critical for elucidating the molecular mechanisms driving cancer progression. This study aimed to profile somatic mutations in bladder cancer patients (N=7) from Bangladesh to provide insights into the genetic alterations underlying this malignancy.
Methods: We performed targeted sequencing of 50 oncogenes and tumor suppressor genes using the Ion AmpliSeq Cancer Hotspot Panel v2 on tumor and matched blood samples from seven bladder cancer patients.
