CA3109090A1 — Diagnostic and therapeutic methods for the treatment of breast cancer

USPTO Abstract

Provided herein, inter alia, are predictive diagnostic, pharmacodynamic, and therapeutic methods for the treatment of breast cancer. In embodiments, the methods and compositions are based, at least in part, on the discovery that the estradiol (E2)-induced score or estrogen receptor (ER) pathway activity score determined from a sample (e.g., a tissue sample, e.g., a tumor tissue sample, e.g., a FFPE, a FF, an archival, a fresh, or a frozen tumor tissue sample) from an individual can be used in methods of determining whether the individual having breast cancer is likely to respond to a treatment including an endocrine therapy, selecting a therapy for an individual having breast cancer; treating an individual having breast cancer; and monitoring therapeutic efficacy of an endocrine therapy, as well as related kits.
