The high negative predictive value suggests that Bladder EpiCheck® may help identify patients without residual tumor and potentially avoid unnecessary Re-TURB. Larger prospective multicenter studies are required to confirm these findings.
BE addition to WLC, with PDD-guided biopsy performed for BE-positive cases, reveals the true performance of BE and WLC and significantly improves the detection of HG disease, allowing earlier intervention with potentially bladder-sparing options.
This review explores the current state of UTUC diagnosis, compares BE with conventional and emerging biomarkers, and discusses its clinical applications, limitations, and future perspectives. The integration of molecular biomarkers like BE into clinical practice has the potential to revolutionize UTUC diagnosis, improving patient outcomes through more precise, non-invasive detection strategies.
UroFollow is the first urine marker-based randomized trial in low/intermediate-risk NMIBC patients. We conclude that 6-monthly marker-based follow-up after negative 3-mo WLC is safe in this cohort. Results of contemporary urine markers suggest that their potential for use in marker-based surveillance, however, requires prospective confirmation.
Urinary biomarkers provide a promising noninvasive alternative for traditional BCa diagnostics with enhanced specificity and the possibility of early diagnosis. Future research should focus on large-scale clinical validation and standardization of biomarkers to facilitate their use in routine clinical practice.
