Abstract A072: Oncuria®-Monitor, a non-invasive test for the detection of recurrent bladder cancer: Cross sectional performance evaluation from a multicenter study

Abstract

Abstract Up to 70% of patients with non-muscle invasive bladder cancer (NMIBC) experience disease recurrence, making it one of the most prevalent cancers in the US. The purpose of this study was to test the performance of Oncuria®-Monitor, a multiplex urinary biomarker assay for the monitoring of voided urine for recurrent bladder cancer. This cross-sectional, multicenter study included a total of 283 subjects with a history of bladder cancer. Voided urine specimens were collected prior to any procedures for multiplex analysis. The diagnostic performance of the biomarker panel was assessed using receiver operator curves (ROC) and descriptive statistical values (e.g., sensitivity and specificity) and compared with the patients’ clinical data and final diagnosis as defined by the results of cystoscopy. Oncuria®-Monitor achieved an overall sensitivity of 94.3%, specificity of 83.6% and negative predictive valuer (NPV) of 96.2% for the detection of recurrent bladder cancer. Patient summary: We conducted a large cross-sectional clinical study for detecting recurrent bladder cancer with a novel, simple urine test (Oncuria®- Monitor), which measures 10 bladder cancer associated proteins in a single voided urine and can be used to detect recurrent bladder cancer. We analyzed urines from 283 patients and demonstrated that Oncuria®-Monitor can detect recurrent bladder cancer with a high degree of accuracy, specifically in patients with high grade or high stage disease. In conclusion, the novel Oncuria®-Monitor urine test can be used to surveil patients with a history of bladder cancer.
