FGFR3 and urinary bladder cancer: Complementary studies amalgamating TERT mutations with FGFR3 evaluations reported enhanced diagnostic accuracy, Yujiro et al. identified that combining cytology with the detection of urine TERT C228T, C250T, and FGFR3 S249C mutations yielded a sensitivity of 78.6% and a specificity of 96% for bladder cancer diagnosis (Hayashi et al., 2019).
