Bladder Cancer Clinical Trial
A Diagnostic for the Early Detection of Bladder Cancer
Summary
To improve upon the non-invasive detection of bladder cancer by further validating a multiplex ELISA assay directed at a bladder cancer-associated diagnostic signature in voided urine samples of patients with a high risk of developing bladder cancer.
Full Description
Environmental exposures, specifically tobacco smoke, increases the risk of many cancers, including bladder cancer. To date, there are no diagnostics capable of detecting bladder cancer early, that is prior to clinical presentation. Because of this severe limitation, nearly 30% of patients initially present with stage 2 and higher bladder cancer. Stage 2 bladder cancer has a 5-year survival of 50%, while stage 3/4 have a 5-year survival of <20%. Ideally, bladder cancer would be preventable. Unfortunate, this has not come to fruition. If these stage 2-4 bladder cancer cases could be detected at Stage 1 (5-yr survival >94%), then its possible to see an improvement in bladder cancer survival rates (21-23).
in this study, a urine-based diagnostic that possesses the potential to accurately identify patients who harbor bladder cancer prior to clinical manifestation will be tested.
Eligibility Criteria
Inclusion Criteria:
Participants must be:
Age 50 years or older
>30 pack year history of tobacco exposure
Free of any malignancy except for the following: adequately treated basal cell or squamous cell skin cancer, in situ cervical cancer, adequately treated Stage I or II cancer from which the patient is currently in complete remission, or any other cancer from which the patient has been disease free for five years. Patients with localized prostate cancer who are being followed by an active surveillance program are also eligible.

Willing and able to give written informed consent
Willing to provide voided urine sample
Be able and willing to complete semi-annual research clinic visits for 4 years
Exclusion Criteria:
Participants must not have:
History of hematuria (microscopic or gross) within 2 years of signing consent.
Previous history of bladder cancer
A known active urinary tract infection or urinary retention
An active stone disease (renal or bladder) or renal insufficiency (creatinine >2.0 mg/dL) - Serum creatinine value can be up to 2 years before consent, otherwise repeat.
An ureteral stents, nephrostomy tubes or bowel interposition
