50-70% of patients with non-muscle invasive bladder cancer (NMIBC) experience relapse of disease.
To establish a panel of protein biomarkers incorporated in a multiplexed microarray (BCa chip) and a classifier for diagnosing recurrent NMIBC.
Urine samples from 45 patients were tested. Diagnostic performance was evaluated by receiver operating characteristic (ROC) analysis.
A multi biomarker panel (ECadh, IL8, MMP9, EN2, VEGF, past recurrences, BCG therapies, stage at diagnosis) was identified yielding an area under the curve of 0.96.
This biomarker panel represents a potential diagnostic tool for non-invasive diagnosis of recurrent NMIBC.
