For this analysis, among the 6 groups constituted for this study, we worked with the two homogenous tumor groups with the higher number of samples: the Ta G1/G2 (FGFR3-mutated) tumor group (28 samples) and the stage T2–4 (FGFR3-non-mutated) tumor group (63 samples). This evidence concerns the gene FGFR3 and neoplasm.
