FGFR3 gene alteration and protein expression in upper urinary tract carcinoma: unsuitability of ureteroscopic biopsy specimens for FGFR3 RNA testing
{{output}}
We aimed to evaluate the suitability of archival ureteroscopic (URS) biopsy specimens for fibroblast growth factor receptor 3 (FGFR3) biomarker analysis in upper urinary tract urothelial carcinoma. Thirty-six patients with upper urinary tract urothelial carcin... ...
