FIGURE 1.

Two Categories of bladder cancer (BLCA) are attributed to Baylor, UROMOL, and Consensus subtyping systems, highlighting their correlation with different stages of local advancement and FGFR3 status. Differentiation‐based color scheme showing features associated with the respective classification. Baylor and UROMOL define NMIBC: Luminal (blue), Luminal‐to‐basal (blue‐grey), and Basal (grey). MIBC is defined by consensus class: Urothelial‐to‐Luminal (blue), Luminal‐to‐basal (blue‐grey), Basal (grey), and neuroendocrine (light yellow). FGFR3 status among subtypes is highlighted in blue (intact FGFR3) or red (mutated FGFR3), with the frequency of FGFR3 alterations in %. Abbreviations: Ba/Sq, basal/squamous; FGFR3, Fibroblast Growth Factor Receptor LumP , luminal papillary, LumNS ,  luminal nonspecified, LumU, luminal unstable, MIBC,  muscle‐invasive bladder cancer, NE,  neuroendocrine, NMIBC, non‐muscle‐invasive bladder cancer,.
