ABSTRACT
To analyze the literature data concerning the results of the main international randomized trials of adjuvant Aromarase Inhibitors [AI] in adjuvant setting for early breast cancer and the impact on daily practice in the management of breast cancer. We selected through a literature review 30 publications concerned the topic of AI They concerned the large ATAC, BIG, MA17 and IES concerning anastrozole, letrozole and exemestane . AI have been compared to tamoxifen in upfront of swich intents and showed a superiority to reduce, mortality rate, controlateral breast cancer risk, a better tolerance profile compared to tamoxifen and a significant benefit in term of disease-free survival. These results made a revolution in the adjuvant BC treatment, leading to the systematic use of upfront AI in menopaused patients. Adjuvant hormonotherapy in menopaused patients is now based on AI and proved its superiority to tamoxifen in term of distant, controlateral risks reduction and disease-free survival, less for overall survival
