Researchers Find Two Biomarkers With Potential To Predict Breast Cancer Spread

Expression of two different proteins taken from primary tumor biopsies is highly associated with spread of breast cancer to nearby lymph nodes, according to researchers who say this protein profile could help identify at an early stage those patients whose disease is likely to metastasize. In the December 15 issue of Cancer Research, the researchers say over-expression of one unidentified protein and under-expression of another is 88 percent accurate in identifying breast cancer that has spread in a group of 65 patients, compared to an analysis of lymph nodes and outcomes. If the predictive and diagnostic power of these proteins is validated, they could be analyzed in primary tumor biopsies that are routinely collected at the time of diagnosis, saving some women from extensive and possibly unnecessary treatment as well as from undergoing a second surgery to collect lymph nodes for analysis, the researchers say. --Click the title of this post to read the full article from its source--
