Spatial Transcriptomics of Micropapillary, Plasmacytoid, and Sarcomatoid Urothelial Carcinoma Reveals Distinct Molecular Landscapes.
PURPOSE Consensus molecular classes of urothelial carcinoma (UC) include basal/squamous (Ba/Sq), luminal papillary (LumP), luminal nonspecified (LumNS), luminal unstable (LumU), stroma-rich, and neuroendocrine (NE)-like. We aimed to determine the consensus molecular classifications of micropapillary (MP), plasmacytoid...
