Microarray analysis has been shown to improve risk stratification of breast cancer. Breast tumors analyzed by hierarchical clustering of expression patterns of “intrinsic” genes have been reported to subdivide into at least four molecular subtypes that are associated with distinct … Continued

Background: A more accurate means of prognostication in breast cancer will improve the selection of patients for adjuvant systemic therapy. Methods: Using microarray analysis to evaluate our previously established 70-gene prognosis profile, we classified a series of 295 consecutive patients … Continued

Breast cancer patients with the same stage of disease can have markedly different treatment responses and overall outcome. The strongest predictors for metastases (for example, lymph node status and histological grade) fail to classify accurately breast tumors according to their … Continued
