Since FGFR3 overexpression correlates with favorable outcomes in NMIBC and MIBC [13,14], we also revealed that UTUC metachronous MIBC may result in a favorable prognosis, which is consistent with the results of our previous report from a multi-institutional cohort study [15]. The gene discussed is FGFR3; the disease is renal pelvis/ureter urothelial carcinoma.
