Abstract

The present invention relates to a method for predicting the response of a patient diagnosed with breast cancer to treatment with an endocrine therapy drug, comprising the steps of: (a) measuring the binding of the estrogen receptor, obtained from a breast cancer tumor from said patient, generating a binding profile, said binding profile comprising the binding of the estrogen receptor from said patient on one or more co-regulator proteins or functional parts thereof in the presence and absence of one or more added phosphatases, (b) measuring the binding of the estrogen receptor, obtained from a breast cancer tumor from said patient, generating a binding profile, said binding profile comprising the binding of the estrogen receptor from said patient on one or more co-regulator proteins or functional parts thereof in the presence and absence of added estradiol, and, (c) predicting from said binding profiles the response of said patient to endocrine drug therapy. The present invention also relates to variant methods hereof and methods for predicting the response of a patient diagnosed with breast cancer to drug treatment and methods for individualized endocrine therapy of a patient diagnosed with an endocrine related disease. The invention also relates to arrays and kits for carrying out these methods.
