Context: Urinary biomarkers are promising as simple alternatives to cystoscopy for the diagnosis of de novo and recurrent bladder cancer.
Objective: To identify a highly sensitive and specific biomarker candidate set with potential clinical utility in bladder cancer.
Materials and methods: Urinary biomarker concentrations were determined by ELISA. The performance of individual markers and marker combinations was assessed using ROC analysis.
Results: A five-biomarker panel (IL8, MMP9, VEGFA, PTGS2 and EN2) was defined from the candidate set.
Discussion and conclusion: This panel showed a better overall performance than the best individual marker. Further validation studies are needed to evaluate its clinical utility in bladder cancer.
Keywords: Biomarkers; bladder cancer; invasiveness; recurrence.
