Pertuzumab and Trastuzumab as Neoadjuvant Treatment in Patients With HER2-Positive Breast Cancer

Summary

This research is being done to determine if early changes on a type of imaging procedure called PET (Positron Emission Tomography) can predict which patients are most likely to respond to the combination of trastuzumab and pertuzumab when given prior to surgery.
