Previous research has shown that triple negative breast tumors make up nearly 20 percent of breast cancers. These cancers do not respond to treatment with targeted therapies such as Herceptin® (trastuzumab).
To investigate new options for these patients, the first clinical trial of whole-genome sequencing for women with triple negative breast cancer was initiated in March 2010, and the first results will be presented during the 2011 CTRC-AACR San Antonio Breast Cancer Symposium, Dec. 6-10, 2011.
Based on mutations uncovered by sequencing, physicians steered the women into treatment protocols for either existing drugs or new agents being evaluated in pharma-sponsored clinical trials. Several patients displayed benefit from treatments physicians selected taking sequencing data into consideration.
Results will be presented at 10:30 am CST, Thursday, Dec. 8, by Joyce O'Shaughnessy, M.D., medical director and co-chair of the Breast Cancer Research Committee, US Oncology Research; a practicing oncologist with Texas Oncology; and the Celebrating Women Chair of Breast Cancer Research at Baylor Charles A. Sammons Cancer Center.
The study, titled "Next Generation Sequencing Reveals Co-Activating Events in the MAPK and PI3K/AKT Pathways in Metastatic Triple Negative Breast Cancers," is sponsored by the Translational Genomics Research Institute (TGen) and US Oncology Research with support from Life Technologies Corporation (NASDAQ:LIFE - News).
