    When should a urologist consider ordering UroVysion as an aid in detecting bladder cancer?

    The only FDA-approved molecular urine test that detects chromosomal changes associated with bladder cancer, UroVysion is used to aid:

    • Initial diagnosis of patients with hematuria
    • Monitoring for recurrent urothelial carcinoma

    An Ordering Option

    Consider these hypothetical circumstances: 

    • A urologist who commonly uses cystoscopy with cytology and sees a high rate of recurrence in bladder cancer patients may choose to order UroVysion as an aid in detecting bladder cancer early. UroVysion detects chromosomal change, an early indicator of cancer; and it is used (in conjunction with, and not in lieu of, standard diagnostic procedures) as an aid in monitoring for tumor recurrence in patients previously diagnosed with bladder cancer.
    • A urologist who commonly uses cystoscopy without cytology and seeks to detect CIS early may order UroVysion as an additional diagnostic aid.
    • A urologist who uses cystoscopy with other tumor markers, and who has found that these markers can be affected by BCG or inflammation, may add UroVysion to the standard diagnostic procedures.

    DNA Probes

    UroVysion is the only FDA-approved urine-based molecular assay that uses DNA probes to detect chromosomal abnormalities. The probes target 4 chromosomes highly associated with bladder cancer. UroVysion in combination with cystoscopy provides a 97% sensitivity.1, 2 The overall specificity of UroVysion is 93%, as indicated in the FDA-approved labeling for UroVysion.

    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

    1. The UroVysion Kit has been optimized for identifying and quantitating chromosomes 3, 7, and 17, and locus 9p21 in human urine specimens.
    2. 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.
    3. 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.
    4. 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.
    5. Technologists performing the UroVysion signal enumeration must be capable of visually distinguishing between the red and green signals.
    6. 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.
    7. 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.
    8. 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.
