THe purpose of this study is to examine the current and (potential) future therapeutic relevance of pharmacogenomics (PGx) testing for a cohort of cancer patients in order to improve quality of life (QOL) in patients receiving clinical care at Mayo Clinic.

This research trial studies genetic profiles in blood and tumor samples from patients with estrogen receptor positive and HER2 negative breast cancer that has spread to other places in the body who are receiving palbociclib and endocrine therapy. Examine the genetic changes associated with the cancer and comparing the genetic material from the cancer tissue with the genetic material found in the blood may help doctors to develop customized treatment for breast cancer.

The purpose of this study is to further advance the ability to practice personalized medicine by learning which new drug agents are most effective with which types of breast cancer tumors and by learning more about which early indicators of response (tumor analysis prior to surgery via magnetic resonance imaging (MRI) images along with tissue and blood samples) are predictors of treatment success.
