Background and study aims
In Europe, more than 120,000 people are diagnosed with bladder cancer each year. Early diagnosis is very important to improve the success of treatment for bladder cancers. However, many patients do not have symptoms at early stages, which makes this challenging. One symptom which may be an early sign of bladder cancer is the presence of blood in the urine. 1 in 5 adults with blood in the urine are found to have bladder cancer. However, blood in the urine can also be a symptom of other conditions so bladder cancers are often missed if the blood in the urine is the only symptom. There is a need for a fast, non-invasive test that can detect bladder cancer at early stages. This study is investigating a new test called Xpert Bladder Cancer Detection, which measures genetic markers of bladder cancer. The researchers want to compare the ability of this new test to detect bladder cancer in patients with blood in the urine, compared to the methods that are currently used. A urine cytology test is currently used, which looks for the presence of abnormal cells in a urine sample.

Who can participate?
Patients who have been referred to the urology clinic with blood in their urine

What does the study involve?
Patient attending the clinic for their cystoscopy procedure will be asked for their permission to collect the leftover urine from this visit. The research team will use the collected sample to assess the new system. The participant will continue with their planned clinic visits and procedures. The research team will collect participants' clinical records such as age, gender, smoking history, current medication, medical history, cytology, cystoscopy, imaging and surgical results.

What are the possible benefits and risks of participating
The research team will only collect the leftover urine, minimising participant involvement and risk. Participants will not benefit directly from taking part in this study. The test result will not be used in the treatment care of the patient and there will be no other test performed on the sample provided. However, participation ensures that the researchers progress in the understanding, design and development of a technique which could support the current recommended procedure for bladder cancer diagnosis. Participation will not change participants' planned care and they will be expected to attend all their scheduled clinic appointments.

Study objectivesThe aim of this study is to test a new bladder cancer detection machine and to determine if this is better than currently used bladder cancer detection methods.
Ethics approval(s)Approved 24/02/2020, South West - Central Bristol Research Ethics Committee (Whitefriars, Level 3, Block B, Lewin's Mead, Bristol, BS1 2NT, UK; +44 (0)207 1048029; centralbristol.rec@hra.nhs.uk), REC ref: 20/SW/0040
Health condition(s) or problem(s) studiedSuspected bladder cancer
InterventionPatient attending the clinic for their cystoscopy procedure will be asked for their permission to collect the left-over urine from this visit. The research team will use the collected sample to assess the new non-invasive system for its diagnostic accuracy. The participant will continue with their planned clinic visits and procedures as per their clinical pathway. The research team will collect participants clinical records such as age, gender, smoking history, current medication, medical history, cytology, cystoscopy, imaging and surgical results.

Primary outcome measurePerformance characteristics of Xpert Detection on the GeneXpert Instrument Systems in comparison to the methods currently used at the site for detecting bladder cancer in patients with haematuria:
1. The number of patients correctly diagnosed with bladder cancer in comparison to the Xpert bladder test (true positive)
2. Sensitivity/specificity of the new index test in comparison to histopathology. Sensitivity will use histopathology as standard. Specificity will be calculated by the ability of the Xpert bladder test to rule out false positives in a clinical setting.
Measured at 18 months
Secondary outcome measuresComparison of the total cost of both diagnosis (cystoscopy and cytology) strategies (with or without Xpert Bladder Cancer Detection), measured at 18 months
