Regulation and New Treatment Strategies in Breast Cancer

J Life Sci (Westlake Village). 2019 Dec 12;1(3):23-38.


Breast cancer classifications are based on the presence or absence of estrogen receptor and progesterone receptor along with the overexpression or amplification of the Her2 receptor. Although the overall 5-year survival rate of breast cancer patients has increased due to the use of targeted therapies, a subset of patients can acquire resistance over time or are unresponsive when presented in the clinic. Novel therapies focusing on molecular pathways and cell cycle regulation currently being used in the clinic may lead to increased response in this subset of patients.
