The patient was referred for systemic therapy with immune checkpoint inhibitors and Enfortumab Vedotin...EUS-guided biopsy with immunohistochemistry is essential to distinguish secondary lesions from primary pancreatic tumors. Accurate diagnosis is crucial to guide systemic therapy, particularly with emerging immunotherapy and antibody-drug conjugates.

Over the past decade, multiple ICIs have demonstrated meaningful clinical activity, and their indications have expanded across treatment lines, including second-line therapy after platinum, first-line therapy for cisplatin-ineligible disease, avelumab maintenance following chemotherapy, and, more recently, combination strategies such as pembrolizumab plus enfortumab vedotin. In this review, we provide a comprehensive overview of currently established and emerging biomarkers of ICI response in UBC, including PD-L1 immunohistochemistry, serum inflammatory markers, tumor mutational burden, histology and molecular subtypes, gene expression patterns and microbiome features. We discuss their strengths, limitations, and potential translational relevance, highlighting ongoing challenges and future directions.

The Food and Drug Administration (FDA)-approved Nectin-4-targeted drug, enfortumab vedotin, has demonstrated substantial efficacy in the treatment of UC...In treatment experiments, covalent 177Lu-FZ-NRs strongly inhibited tumor growth without obvious toxicity. In summary, our novel Nectin-4-targeted covalent bicyclic peptide radioligands provide new molecular imaging tools for the non-invasive assessment of Nectin-4 and establish a foundation for UC-targeted radiotherapy.

We found that tumor samples from patients with cancer of the urinary tract that had spread to the brain had higher expression of a gene called NECTIN4 (67%). Our findings suggest that treatments targeting NECTIN4, such as a drug called enfortumab vedotin with or without pembrolizumab, might benefit patients with brain metastases, especially if their tumors have high NECTIN4 levels.

Using plasma alone, APEX enables classification of prognostically relevant basal and classical pancreatic cancer subtypes and identifies plasma-inferred NECTIN4 expression as a biomarker of response to enfortumab vedotin in metastatic bladder cancer. Together, these findings establish APEX as a biopsy-free approach for profiling tumor transcriptional states and extend liquid biopsy beyond genomic alterations to clinically relevant gene expression programs.
