From the big randomized clinical trials there are evidences that adjuvant endocrine therapy for hormone-sensitive early breast cancer in postmenopausal women should include an aromatase inhibitor (AI). Anastrozole or letrozole should be used upfront for 5 years (ATAC and BIG 1-98), the sequential approach of tamoxifen for 2-3 years, followed by anastrozole or exemestane for 2-3 years is a reasonable alternative (ABCSG8, ARNO 95, IES, ITA), and mostly in patients with node-positive disease completing 5 years of tamoxifen should be offered letrozole up to 4-5 years (MA-17). In each of these trials incorporation of an AI resulted in significant improvement in study endpoints. Further results will be needed to establish the optimal beneficial effect, use, duration and safety of adjuvant AI therapies.
