In the war on cancer, perhaps there is nothing more powerful in a physician's arsenal than early detection. Despite recent advances in early detection and treatment, breast cancer remains a common and significant health problem in the United States and worldwide. Approximately one in ten women will get breast cancer in their lifetime and more than half of women with late stage cancer (II and III) have no cure or effective therapeutic available.
Using a new, powerful method for rapidly screening molecules associated with disease, proteomics expert Joshua LaBaer and colleagues from the Biodesign Institute at Arizona State University have identified a broad panel of 28 early predictors, or biomarkers, that may one day aid in the early diagnosis of breast cancer.
"We do not have any available blood markers for breast cancer," said LaBaer, a Virginia G. Piper Chair in Personalized Medicine at ASU who directs the Center for Personalized Diagnostics at the Biodesign Institute. "Our hope is to combine a new type of blood test with mammography screening to aid in the early detection of breast cancer."
The findings represent the first demonstration of a custom protein array technology deployed to find biomarkers in breast cancer patients before they were clinically diagnosed for cancer. These biomarkers were specific for breast cancer patients and not in healthy women or women with a benign form of breast disease.
Their findings appear in the American Chemistry Society's Journal of Proteome Research.
The LaBaer lab is involved in a quest for biomarkers that detect early disease and distinguish benign breast disease from invasive cancers to guide patient and doctor decisions. LaBaer is an expert in a burgeoning field that strives to understand the global role of protein function, called proteomics, that plays a powerful and relevant role in the discovery of biomarkersunique molecular fingerprints of disease---th
