Clinical Information
Discusses physiology, pathophysiology, and general clinical aspects, as they relate to a laboratory test
Cystoscopy and urine cytology have been the primary methods for detecting urothelial carcinoma (UC). Unfortunately, urine cytology has relatively poor sensitivity for the detection of recurrent UC. This is problematic because patients who have undetected recurrent tumors may have tumor progression that places them at increased risk of developing metastatic UC.
The UroVysion assay is a fluorescence in situ hybridization (FISH) assay for the detection of recurrent UC. The UroVysion probe set contains probes to the centromeres of chromosomes 3, 7, and 17, and a locus-specific probe to the 9p21 band (site of the P16 tumor suppressor gene). The UroVysion assay detects cells with chromosomal abnormalities consistent with a diagnosis of UC. Studies have shown that the assay has higher sensitivity than urine cytology but similar specificity for the detection of recurrent UC. The UroVysion assay also demonstrates higher specificity than the BTA-stat assay for recurrent UC.
Reference Values

An interpretive report will be provided.
Interpretation
Provides information to assist in interpretation of the test results
Lower Tract Samples:
Abnormal: any specimen satisfying 1 of the following criteria:
-Four or more cells with gains of 2 or more chromosomes
-Ten or more cells with a gain of a single chromosome or 10 or more cells with tetrasomic signal patterns (ie, 4 copies for each of the 4 probes)
-Homozygous deletion of the 9p21 locus in 20% or more of the cells analyzed
For cases that are abnormal, the percentage of abnormal cells and type of chromosomal abnormality (ie, polysomy, trisomy, tetrasomy, or homozygous 9p21 deletion) are indicated in the test report.
Negative:
-Fewer than 4 cells with gains of 2 or more chromosomes
-Fewer than 10 cells with gain of a single chromosome or tetrasomy
-Less than 20% of cells with homozygous 9p21 deletion
Upper Tract Samples:
Abnormal: any upper tract specimen satisfying 1 of the following criteria:
-Four or more hypertetrasomy cells with at least 5 copies of 2 or more chromosomes
-Ten or more cells with a gain of a single chromosome or 10% or more cells with tetrasomic or near-tetrasomic signal patterns (ie, 4 copies for each of the 4 probes)
-Homozygous deletion of the 9p21 locus in 20% or more of the cells analyzed
Negative:
-Fewer than 4 cells with hypertetrasomy with at least 5 copies of 2 or more chromosomes
-Fewer than 10% of cells with tetrasomy
-Less than 20% of cells with homozygous 9p21 deletion
Cautions
Discusses conditions that may cause diagnostic confusion, including improper specimen collection and handling, inappropriate test selection, and interfering substances
Significant cell populations with chromosomal gains or homozygous 9p21 deletion indicate that the patient has a genitourinary malignancy, which is most frequently bladder cancer or, much less likely, a metastatic involvement of the genitourinary tract. However, the patient may have another genitourinary malignancy (eg, renal pelvic or ureteral transitional cell carcinoma, prostatic carcinoma with urethral invasion, renal cell carcinoma, or metastatic cancer involving the genitourinary tract).
This assay is intended for detecting tumors and does not provide information on tumor stage.
Biopsy may help clarify the diagnosis and tumor stage.

Method Description
Describes how the test is performed and provides a method-specific reference
Urinary cells are harvested, fixed, and placed on a slide. The UroVysion probe set, which contains fluorescently labeled DNA probes specific to the centromeres of chromosomes 3, 7, 17, and to the 9p21 locus is hybridized to the cells on the slide. The slide is washed and counterstained with 4',6-diamidino-2'-phenylindole dihydrochloride (DAPI) stain. Fluorescence microscopy with unique band filters is then used to scan the slide for atypical cells (eg, cells with nuclear enlargement or irregularity). These cells are assessed for gains of chromosomes (3, 7, 17) or homozygous 9p21 deletion. If the number of cells with chromosomal gains (polysomy or trisomy) or homozygous 9p21 deletion observed on scanning is sufficient to consider the test result positive, the percentage of transitional cells with polysomy, trisomy, or homozygous 9p21 deletion is determined.(Halling KC, King W, Sokolova IA, et al.
