Primary Objective:~- To evaluate serial multiparametric MRI as an early marker for tumor immune response to an immune checkpoint inhibitor agent~Secondary Objective:~To assess the potential of early treatment imaging changes on MRI to discern final tumor treatment response~To assess the prognostic potential of MRI features~Correlative:~To correlate MRI features with immunophenotypes (i.e. hot and cold tumors)~To evaluate the association of MRI features with other known biomarkers of immune checkpoint inhibitor response
This study is looking at how an imaging test could help doctors understand if a patient with early breast cancer will respond to drugs that use the patient's immune system to fight cancer.
