The ability to test for and detect prostate cancer with minimal invasiveness has the potential to reduce unnecessary prostate biopsies.
A recent study was conducted as part of a clinical investigation for the development of an FISH probe panel on urine samples for more accurate detection of prostate cancer. Chromosomes Y, 7, 10, 20, 6, 8, 16, and 18 were polysomic in most prostate carcinoma cases. Of these eight chromosomes, chromosomes 7, 16, 18, and 20 were identified as having the highest clinical performance as a fluorescence in situ hybridization test and used to manufacture the fluorescence in situ hybridization probe panels. The OligoFISH(®) probes performed with 100% analytical specificity. When the OligoFISH(®) probes were compared with the biopsy results for each individual, the test results highly correlated with positive and negative prostate biopsy pathology findings, supporting their high specificity and accuracy.
This probe panel has shown is ease of use with high specificity, high predictive value, and accuracy in identifying prostate cancer in voided urine after digital rectal examination with pressure. The test is likely to have positive impact on clinical practice and advance approaches to the detection of prostate cancer.
