November 2019—We read with interest the case described by Vormittag-Nocito, et al., of metastatic bladder adenocarcinoma with associated molecular pathology findings (September 2019). However, we would like to point out what we believe to be an important update related to the significance of FGFR3 alterations in urothelial carcinoma. When referring to TP53 and FGFR3 alterations in urothelial carcinoma, the authors write that “no targeted therapy or prognostic implications can be made about these mutations at this time.”
