Brief Summary
This observational study is designed to collect urine and relevant clinical information from patients who have a known diagnosis of bladder cancer and currently on clinically driven surveillance. The study aims to compare the urine test to the flexible cystoscopy procedure (which the patient is already scheduled).

Outcome Measures
Primary Outcomes (1)
Proportion of participants with bladder cancer who are correctly identified as having cancer (true positives) and no cancer (true negatives) by the Cxbladder test.
To validate the Performance Characteristics (sensitivity, area under the ROC curve, positive and negative predictive values and test negative rate) of the Cxbladder for the detection of recurrent UC in the absence of inflammation in patients with a recent history of urinary tract UC who have been treated according to standard practice and are undergoing routine investigative cystoscopy. The gold standard for determination of clinical truth is cystoscopy confirmed by pathology, plus any follow up investigations relating to the current visit.
24 months
Secondary Outcomes (5)
Detection rates of Cx bladder test
24 months
Comparison of Cxbladder theoretical capacity to reduce use of flexible cystoscopy for the monitoring for recurrence of urothelial carcinoma
24 months
Comparison of the Cxbladder test and cytology test performance on the same sample
12 months
Performance of Cxbladder test in atypical findings of cytology and cystoscopy
24 months
Examine urinary microbiome profile in patients with urothelial cancer
24 months
Study Arms (1)
UC monitoring patients
Patients undergoing investigative cystoscopy for the detection of urothelial carcinoma as part of a standard-of-care schedule of investigations. All patients will have urine samples taken and analyzed for urine cytology and Cxbladder. No results for any tests under evaluation in this study are provided to the clinician for diagnostic purposes.
Interventions
Cxbladder Monitor is a non-invasive UC detection test measuring five messenger RNA (mRNA) biomarkers present at elevated levels in patients presenting with urothelial carcinoma and also two clinical variables (whether the previous tumor was primary or recurrent and the time since the previous tumor was resected).
Eligibility Criteria
Patients undergoing flexible cystoscopy on a clinically determined surveillance schedule who have been previous diagnosed with bladder cancer are eligible. These patients are recruited prior to their investigation, and a urine sample collected. The patients clinical events are then followed (observed) for 12 months following the urine sample collection.
You may qualify if:
- Patient is undergoing investigative cystoscopies for the monitoring of recurrence of urinary tract UC at intervals prescribed by the clinical practitioner
- Patients on an "all-comers" basis
- Positive diagnosis for primary or recurrent bladder tumour within the past 5 years
- Able provide a voided urine sample of the required minimum volume
- Able to give written consent
- Able and willing to comply with study requirements
- Aged 18 years or older
You may not qualify if:
- Prior genitourinary manipulation (flexible or rigid cystoscopy / catheterisation, urethral dilation) in the 14 days before urine collection,
- Patients who had exposure to intravesical BCG, had completed induction BCG but without a subsequent clear cystoscopy
- Recent history of glomerulonephritis, nephrosis or other renal inflammatory disorders,
- Recent history of pyelonephritis
- Total cystectomy of the bladder, neo bladders and illeal conduits
- Previous muscle invasive bladder tumour (pT2 or greater)
