The objective of this study is to use a DEK ELISA to quantitatively measure DEK protein in the urine of patients suspected of having bladder cancer. The measurement of urine DEK protein, relative to an established cut-off, is correlated with the presence or absence of bladder cancer.

Primary Outcome Measures:
  • Histology [ Time Frame: Up to 1 year after cystoscopy/biopsy ]

Secondary Outcome Measures:
  • Cystoscopy [ Time Frame: up to 3 months after collection ]
  • Cytology [ Time Frame: up to 3 months after collection ]

Biospecimen Retention:   None Retained

Estimated Enrollment: 1000
Study Start Date: March 2012
Estimated Study Completion Date: December 2016
Primary Completion Date: March 2014 (Final data collection date for primary outcome measure)
TCC positive
subjects with hematuria, dysuria or other irritative voiding symptoms, without evidence of other causative factors such as infections or stones that are found to have a bladder tumor confirmed by histopathology
TCC negative
subjects with hematuria, dysuria or other irritative voiding symptoms, without evidence of other causative factors such as infections or stones that are found to NOT have a bladder tumor by histopathology or clinical observation.

Detailed Description:

Sample Collection:

Urine samples used in the study will be collected immediately prior to the urological evaluation procedure and stored at -80 oC. Urine samples will be sent to sponsor and remain at -80o C until analysis.

Clinical Data Collection:

All subject and clinical information will be recorded on the form in section 9.3. Enrollment Checklist and Case Report Form (CRF). Information regarding the history of hematuria and urine cytology will be recorded. In addition, non-identifying information including age, sex, race, smoking history, alcohol consumption, occupational exposure to chemicals or dyes, history of urologic disorder or disease, history of irritative voiding symptoms, history of urinary tract infection, history of pelvic irradiation, and analgesic abuse will be recorded. The Investigators will also be asked to provide information from the subjects' medical records for up to one (1) year after their enrollment and sample collection. In particular, diagnosis of TCC, other malignant diseases, or non-malignant urogenital conditions will be provided.
