Urinary Analysis of <i>FGFR3</i> and <i>TERT</i> Gene Mutations Enhances Performance of Cxbladder Tests and Improves Patient Risk Stratification

Abstract

PURPOSE: genes, in addition to the current 5 mRNA biomarkers and clinical risk factors. MATERIALS AND METHODS: Two multicenter, prospective studies were undertaken in: (1) U.S. patients with gross hematuria aged ≥18 years and (2) Singaporean patients with gross hematuria or microhematuria aged >21 years. All patients provided a midstream urine sample and underwent cystoscopy. Samples were retrospectively analyzed using enhanced Cxbladder-Triage (risk stratifies patients), enhanced Cxbladder-Detect (risk stratifies patients and detects positive patients), and the combination enhanced Cxbladder-Triage × Cxbladder-Detect. RESULTS: < .001). CONCLUSIONS: This study in ethnically diverse patients with hematuria showed the analytical validity of the enhanced Cxbladder tests.
