Mortality from breast cancer continues to decline in North America and other parts of the world (1,2). This improvement was initially attributed to widespread adoption of mammography screening recommendations. However, much of the recent ongoing decline in breast cancer mortality is most likely a result of the increased use of systemic adjuvant chemotherapy and hormonal therapy. The benefit from adjuvant treatment is observed not only in women with axillary lymph nodepositive disease but also in women diagnosed with the most common presentation in North America: axillary lymph nodenegative breast cancer. For patients with hormone receptornegative breast cancer, systemic chemotherapy improves the odds of disease-free and overall survival to the same relative degree as it does for patients with lymph nodepositive disease, whereas hormonal therapy such as tamoxifen is not helpful for patients with receptor-negative disease. A meta-analysis of worldwide adjuvant clinical trials by the Early
