What this trial studies

This observational study aims to establish a biobank of blood and urine samples from patients diagnosed with bladder carcinoma. The primary objective is to support the development of non-invasive tests for the early detection of bladder cancer. Participants will undergo sample collection and have their medical records reviewed while enrolled in the study. This approach allows researchers to gather valuable biological materials that can aid in advancing diagnostic methods for bladder cancer.

Who should consider this trial

Good fit: Ideal candidates for this study are adults over 18 years who have undergone evaluation for hematuria.

Not a fit: Patients with known cancer outside of bladder carcinoma or those with recurrent muscle invasive bladder cancer may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved early detection methods for bladder cancer, potentially increasing survival rates.

How similar studies have performed: Other studies have successfully established biobanks for cancer research, indicating that this approach has potential for meaningful contributions to early detection methods.

* Patient has had a biopsy to the target organ and/or lesion within 3 days before collection
* Patient has undergone cystectomy or cystoprostatectomy
* Patient has transurethral instrumentation (placement of urinary catheter) within 7 days prior to urine collection
* Patient has had a urinary tract infection within 14 days prior to urine collection
* Patient has chronic indwelling urinary catheter
