And even in the patients who initially respond, at some point they all develop resistance to treatment, progression, and finally death 18, There are several hypotheses for acquired hormonal resistance: altered expression of ER coregulators, downregulation of ER expression, ER mutations and ligand-independent activation of ER - probably, in real life situations experiencing a combination of all hormonal cancer treatment side effects.
