FGFR3 and urothelial carcinoma: As demonstrated in our data, in non-muscle-invasive urothelial carcinoma, our results showed a slight but non-significantly higher incidence of FGFR-3 mutation, whereas compared to data provided by TCGA, the incident of FGFR-3 mutations in our variant was significantly higher compared to unselected variants of urothelial carcinoma.
