Subgroups within triple-negative breast cancers?


Question from PhoebeJ: Do we have further knowledge about subgroups within the triple-negative breast cancers?
Answers - Nicholas Robert, M.D. In terms of triple-negative breast cancer -- that is, defined by patients who are ER-negative, progesterone-receptor-negative, and HER2-negative -- this is not a uniform group. There are some patients who have a basal cell type. There are some patients who have a mutation in BRCA1, and in the future as we begin to do genomic studies on a more regular basis where research will support what is important to do, we will find that the triple-negative group, just like breast cancer, is composed of multiple subsets. The hope many of us have as we develop a better understanding of the different subsets of breast cancer is that we will be able to match systemic treatments that are more specific to each subset.

On Wednesday, June 24, 2009, our Ask-the-Expert Online Conference was called Updates from the ASCO Annual Meeting. Nick Robert, M.D. and Beth Baughman Dupree, M.D., F.A.C.S. answered your questions about the newest findings on risk, screening, treatment, and more.
