Abstract:

Neo-adjuvant endocrine therapy has opened new alternatives for locally advanced breast cancer. Such therapy, which has permitted us to expand the treatment role of neo-adjuvant therapies, may be of great benefit to patient groups such as the elderly, those not suited for chemotherapy, and those whose response may not be optimal. This therapy also may be able to help us identify agents that could improve outcomes in the adjuvant setting as well as possible biologic predictors for outcome. The latest generation of endocrine therapy for breast cancer, aromatase inhibitors, has proved superior to tamoxifen in terms of toxicity and efficacy in the adjuvant setting and is currently being studied in other clinical trials. Current findings indicate that these agents are less toxic and better tolerated than neo-adjuvant chemotherapy and that third-generation anti-hormomal therapy offers improved tumor response compared with tamoxifen, which has resulted in increased breast conserving surgery. Biomarker findings of improved response in tumors that are both estrogen receptor positive and HER-2 positive as well as progesterone receptor positivity only will be important for planning future selective treatment and clinical trials.
