The hormone - dependence of breast cancer has been established for over a century but new investigations in its knowledge have gone away introducing with the step of years. Estrogen and progesterone receptors have been standards for the guide of treatment, but recently waste of cholesterol has emerged as a new perspective for the guide of treatment. It has been known for a long time that 5% of patients that did not show estrogen and progesterone receptors in their tumors have response to hormone-therapy. A new way of hormone-dependence is the formula of the waste of cholesterol, it is based on the levels of lipoproteins, LDL and HDL cholesterols, which can identify the endocrine balance.
Material and Methods
Based on our results with Stage III patients with negative expense of cholesterol that were not medicated with tamoxifen after chemotherapy and had 100% relapses before 5 years, we analysed a RE- RPG - Her2 3+ patient with negative waste of cholesterol and proposed her to receive adjuvant treatment with tamoxifen after adjuvant chemotherapy.
