Non-Small Cell Lung CancerIn August of 2011, Abbott launched the Vysis ALK Break Apart FISH Probe Kit, for use with Pfizer's XALKORI® (crizotinib) ALK-inhibitor, to identify the approximately 3-5% of Non-small Cell Lung Cancer (NSCLC) patients with the ALK gene rearrangement. This collaboration was a breakthrough in the advancement of companion diagnostics in that it was designed to tailor treatment to a patient’s specific genetic profile. Since the U.S. launch, the product has been made available in more than 70 countries, providing patients like Richard Heimler, a 10-year NSCLC survivor, an opportunity for better treatment outcomes. Worldwide, approximately 1.8 million people are diagnosed with lung cancer annually,1 accounting for 13% of all cancers. Of these patients, roughly 85% to 90% have non-small cell lung cancer (NSCLC).2 Abbott’s Vysis ALK – the first FDA approved test for identification of ALK gene rearrangements:

Breast CancerAbout 20-25% of the 1,200,000 women worldwide diagnosed each year with breast cancer have amplification of the HER-2 gene. Detection of HER-2 amplification is important in the diagnosis, prognosis, selection of appropriate therapy and prediction of therapeutic outcome in certain cancers.3 Since its approval in 2001, the targeted therapy, Herceptin®, has been improving the odds for HER-2 positive patients like Roseann Kolb. HER-2 amplification and subsequent overexpression of the gene product have emerged as a key prognostic and therapeutic marker in breast cancer. Amplification of this gene is found to be associated with rapid proliferation, shorter disease-free survival and poorer overall survival in both node-negative and node-positive ductal breast cancers. With the advent of monoclonal targeted therapies such as Herceptin® (Trastuzumab), accurate HER-2 assessment is a critical component in determining appropriate therapy selection. Both the National Comprehensive Cancer Network (NCCN®) and the American Society of Clinical Oncology (ASCO®) recommend HER-2 assessment for all invasive breast cancers. Abbott’s PathVysion® HER-2 DNA FISH Probe Kit is a precise test that provides clinicians with accurate and reliable HER-2 status information that is used to make critical decisions about therapy. PathVysion® is one of the preferred tests for assessing HER-2 status:3

The test uses fluorescent probes to "paint" the HER-2 genes in the tumor cell nucleus, to see if the number of gene copies is normal or not. Interpretation is objective - results are obtained by counting the fluorescent signals (dots). In addition, because this test measures genetic material, which is very stable, tissue preparation has very little effect on test outcome. PathVysion HER-2 DNA Probe Kit
