Bostwick Laboratories is proud to offer ProstaVysion, a prognostic genetic panel for prostate cancer.
A tissue-based panel, this test examines two major mechanisms of prostate carcinogenesis: ERG gene
fusion/translocation and the loss of the PTEN tumor suppressor gene. By examining these two markers,
ProstaVysion is able to provide a molecular analysis of prostate cancer aggressiveness and long-term
patient prognosis. The ProstaVysion Score summarizes patient results with information present in published
medical literature for a projected outcome of prostate cancer. These results are beneficial to physicians
for guiding patient treatment decisions.
- ERG gene fusions are found in 40% of primary prostate cancers [Carver 2009]
- Associated with a more aggressive phenotype
- Correlates with cancer stage, Gleason score, grade and cancer-specific survival rates [Yoshimoto 2009]
- Key tumor suppressor gene in prostate cancer
- Deletion of PTEN occurs in 20-40% of localized prostate cancers and up to 60% of metastases [Han 2009]
Both of these ProstaVysion panel markers provide useful, actionable and cost-effective prognostic information.
ProstaVysion is available exclusively from Bostwick Laboratories, your partner in premium urological services.
