SALT LAKE CITY, Dec. 7, 2012 (GLOBE NEWSWIRE) -- Myriad Genetics, Inc. (Nasdaq:MYGN) announced today that a presentation entitled "Homologous recombination deficiency (HRD) score predicts pathologic response following neoadjuvant platinum-based therapy in triple-negative and BRCA1/2 mutation-associated breast cancer (BC)," was presented on Friday, December 7, 2012 at the CTRC-AACR San Antonio Breast Cancer Symposium in San Antonio, Texas. The study demonstrates that Myriad's HRD test strongly predicts which primary tumors will respond to platinum-based combination therapy in patients with triple-negative breast cancer.
Triple-negative breast cancer describes breast tumors that lack estrogen receptor, progesterone receptor and HER2. This type of breast cancer tends to be more aggressive than other subtypes of breast cancer and has not been amenable to targeted therapies. The platinum class of drugs kill tumors by causing DNA damage inside the tumor and may be particularly effective against tumors that have lost their ability to repair DNA.
Researchers at Stanford University School of Medicine and Myriad Genetics studied the pathologic response of tumors in patients with triple-negative breast cancer to a carboplatin-based therapy and showed that the HRD test can significantly predict patient response to such therapy. 70% of patients with an HRD score ?10 responded to the carboplatin treatment, compared to only 20% of patients with an HRD score < 10 (p=0.0001). Using the HRD test instead of BRCA status identified more than 3 times as many patients as likely responders. The HRD test may prove to be a very important tool in guiding the treatment of patients with triple-negative breast cancer.
"DNA repair deficiency is believed to be a property of a significant number of triple-negative breast tumors," said Dr. James Ford of Stanford University School of Medicine, the senior author of the study. "The HRD score has enabled us to effectively identify the majority of responders with high accuracy."
Many breast tumors are believed to be deficient in DNA repair capacity.?Myriad's HRD test is designed to predict patient response to DNA damaging agents such as platinum drugs and PARP inhibitors that may be more effective against these subsets of breast cancer.?With further research, the use of the HRD test may become an important tool to guide treatment decisions in all breast cancer patients.
