简要总结

This study aims to compare the correlation between FGFR mutations found in bladder cancer tissues and urine to develop a companion diagnostic method for predicting the effect of FGFR inhibitors using urine samples of the patients with urothelial cancer.

详细描述

This study targets 92 patients with urothelial cancer, whose tissue (from scheduled surgery) and urine samples can be obtained, regardless of the treatment stage.

■ Examination Methods

  • FGFR mutations in bladder cancer tissues will be analyzed using next-generation sequencing and current companion diagnostic methods.
  • FGFR mutations in urine samples obtained from patients with bladder cancer will be analyzed using nanowires.
  • Bladder cancer subtyping will be performed by RNA sequencing of tumor tissues or other methods.
  • Analysis of paired tissues before and after chemotherapy will be performed on transurethral resection of bladder tumor (TUR-BT) and cystectomy tissues before and after neoadjuvant chemotherapy.
