Diagnosis / Prognosis - Cxbladder

patients with hematuria undergoing investigation for UC - Patients will be recruited from those presenting with hematuria and undergoing investigative cystoscopy for the determination of possible urothelial carcinoma. This includes patients referred via imaging or from other departments for assessment of hematuria. Microscopic hematuria is defined as > 3 red blood cells per high-powered microscopy field for a properly collected urine sample.


Diagnosis / Prognosis: Cxbladder
The Cxbladder Detect test, developed by Pacific Edge Ltd (O'Sullivan 2012; Holyoake 2008; National Health Committee 2015b) is a molecular diagnostic test, which consists of five mRNA transcripts measured in a small volume of urine.

Outcomes
Primary outcome [1] 0 0
Proportion of participants with bladder cancer who are correctly identified as having cancer (true positives) and no cancer (true negatives) by the Cxbladder test.
Timepoint [1] 0 0
The outcome measure will be assessed by 6 months after trial completion.
Primary outcome [2] 0 0
Probability that patients identified as having cancer and no cancer by the Cxbladder test truly have cancer (positive predictive value; PPV), and truly have no cancer (negative predictive value; NPV) respectively.
Timepoint [2] 0 0
Time Frame: The outcome measure will be assessed by 6 months after trial completion.
Secondary outcome [1] 0 0
Comparison of the Cxbladder test's sensitivity, specificity, PPV and NPV with that of Cytology.
Timepoint [1] 0 0
The outcome measure will be assessed by 6 months after trial completion.
Secondary outcome [2] 0 0
To compare the theoretical clinical outcome of patients tested using Cxbladder tests
Timepoint [2] 0 0
The outcome measure will be assessed by 6 months after trial completion.
Secondary outcome [3] 0 0
To compare the theoretical clinical outcome of patients tested using Cxbladder signatures before investigative cystoscopy with evaluation by cystoscopy alone to establish the true proportion requiring cystoscopy.
Timepoint [3] 0 0
The outcome measure will be assessed by 6 months after trial completion.
Secondary outcome [4] 0 0
Performance characteristics of Cxbladder Triage and Cxbladder Detect compared with results generated at other clinical sites
Timepoint [4] 0 0
The outcome measure will be assessed by 6 months after trial completion.
