It is clear that letrozole and anastrozole provide significant benefits for patients with breast cancer. However, possible differences in efficacy have been suggested by varying degrees of aromatase inhibition and effectiveness in the neoadjuvant and first-line settings. Analyses of aromatase inhibitor-treated patient subgroups within the Arimidex, Tamoxifen, Alone or in Combination trial and Breast International Group 1-98 trial, and the National Cancer Institute of Canada Clinical Trials Group's MA.17 study, have also suggested some differences in efficacy. The question is how best to maximize these differences to benefit specific patient subgroups, such as postmenopausal women with node-positive disease. Nodal status is one of the strongest prognostic factors for breast cancer recurrence and several studies have shown that patients with node-positive disease are at higher risk for early relapse. It is thought that patients at increased risk for early relapse may be better treated with an aromatase inhibitor upfront, but the guidelines are unclear as to which aromatase inhibitor should be used. To answer this important question quickly, the Femara Anastrozole Clinical Evaluation (FACE) trial is recruiting node-positive patients and randomizing them to receive either early adjuvant letrozole or early adjuvant anastrozole. The trial has been designed to differentiate between the two drugs in the shortest possible time frame by using patients at increased risk of early recurrence of breast cancer, so that the required number of events to initiate analysis will be obtained more quickly. In total, 4000 patients who have recently undergone surgery for node-positive primary breast cancer (and who have no clinical or radiological evidence of recurrent disease or metastasis) are being enrolled around the world. The FACE trial will not only provide an efficacy evaluation between these two aromatase inhibitors but also provide a valuable head-to-head com. The results are expected to further refine the treatment paradigm for breast cancer in postmenopausal patients with node-positive disease.
