Thrilled to share our new analysis from CheckMate 901! 🟡In N+ only metastatic UC, Nivolumab + chemo doubled complete response rate vs chemo alone (63% vs 34%) and prolonged PFS (HR 0.38) and OS (HR 0.58). ➡️A new horizon for a distinct subgroup. European Urology OncoAlert

Great editorial on Very High-risk NMIBC with real-world data challenging current guidelines on upfront radical cystectomy. Current progress in BCG-naïve NMIBC might enable bladder-preservation in more patients: CREST (BCG+sasanlimab), ALBAN (BCG+atezolizumab), POTOMAC

Ever wondered how to cost effectively implement molecular subtyping of muscle invasive #bladder #cancer ? We just published a publicly available pipeline relying on NextFlow and Quantseq to assign molecular consensus subtype in large scale! Costs per sample <200 💵!!!!! ➡️ ready

🚨 New preprint drop! MOSAIC builds a pan-cancer spatial + single-cell multi-omics atlas of thousands of tumors, exposing the fine-grained mosaic of intra-tumoral heterogeneity and immune niches. A game-changer for #PrecisionOncology and data-hungry AI models. More to come (much

Different novel therapies in NMIBC are approved #ASCO Andrea Necchi Matt Galsky Most are being tested in BCG pretreated patients. All have activity & many have a favourite, but with small single arm trials no one knows which is best. Now there are choices we should randomise?
