UROVYSION® BLADDER CANCER KIT RESULTS
Clear and reliable test results
A non-invasive test, UroVysion requires the patient to provide a urine sample. The urologist sends the specimen to a lab such as PersonalizeDx, where four DNA probes are used to identify chromosomal abnormalities.
After running the test, PersonalizeDx sends a digital image, typically within 72 hours, to the pathologist, who reads and reports the results to the urologist. If there are no chromosomal changes, the test results will resemble the image on the left. If chromosomal changes are present, the results will resemble the image of an abnormal cell on the right.
Images are examples of UroVysion; individual results may vary.
If the UroVysion test results are positive, the urologist may order other tests to determine the following information:
- Stage: how far the cancer has spread, whether it is superficial, invasive, or in an advanced stage.
- Grade: how well-developed the cells look under the microscope; whether they are low-, medium-, or high-grade.
The urologist then can proceed with the goal of developing an appropriate treatment plan for the patient.
Intended Use: The UroVysion Bladder Cancer Kit (UroVysion Kit) is designed to detect aneuploidy for chromosomes 3, 7, 17, and loss of the 9p21 locus via fluorescence in situ hybridization (FISH) in urine specimens from persons with hematuria suspected of having bladder cancer. Results from the UroVysion Kit are intended for use in conjunction with and not in lieu of current standard diagnostic procedures, as an aid for initial diagnosis of bladder carcinoma in patients with hematuria and subsequent monitoring for tumor recurrence in patients previously diagnosed with bladder cancer.
Warnings and Limitations
- The UroVysion Kit has been optimized for identifying and quantitating chromosomes 3, 7, and 17, and locus 9p21 in human urine specimens.
- The performance of the UroVysion Kit was validated using the procedures provided in the package insert only. Modifications to these procedures may alter the performance of the assay.
- The clinical interpretation of any test results should be evaluated within the context of the patient’s medical history and other diagnostic laboratory test results.
- UroVysion assay results may not be informative if the specimen quality and/or specimen slide preparation is inadequate, e.g., the presence of excessive granulocytes or massive bacteruria.
- Technologists performing the UroVysion signal enumeration must be capable of visually distinguishing between the red and green signals.
- Positive UroVysion results in the absence of other signs or symptoms of bladder cancer recurrence may be evidence of other urinary tract related cancers—e.g., ureter, urethra, renal, and/or (in males) prostate—and further patient follow-up is justified. In a study conducted on patients with hematuria, 3 patients whose initial bladder cystoscopy was negative, were subsequently diagnosed with renal cancer within 6 months of this initial study visit. All 3 of these cases tested positive by UroVysion.
- If UroVysion results are negative, but standard clinical or diagnostic tests (e.g., cytology, cystoscopy) are positive, the standard procedures take precedence over the UroVysion test. Although the UroVysion Kit was designed to detect genetic changes associated with most bladder cancers, there will be some bladder cancers whose genetic changes cannot be detected by the UroVysion test.
- Stage Ta solitary tumors smaller than 5mm could not be detected by UroVysion FISH. UroVysion FISH results are dependent on the amount of tumor cells that are deposited on the slide.
