METHODS OF DETERMINING BREAST CANCER PROGNOSIS

摘要

Disclosed herein are methods of determining a diagnosis or prognosis for a subject with a breast tumor. In one embodiment, the method includes determining an amount of EPS8-like 1 (EPS8L1) in the sample (such as an amount of EPS8L1 nucleic acid or protein) and comparing the amount of EPS8L1 in the sample to a control. The subject is determined to have a poor prognosis (such as decreased likelihood of survival) if the amount of EPS8L1 in the sample is increased compared to the control. In some embodiments, the methods further include administering a treatment to a subject determined to have a poor prognosis, such as administering an ErbB2-targeting therapy to the subject.
