Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

This is a feasibility study to gain preliminary information regarding whether breast imaging with or without a core needle biopsy after neoadjuvant chemotherapy (NAC) but before surgery can accurately predict complete pathologic response (pCR) in women with triple negative or HER2- positive breast cancer. pCR is defined as having no residual invasive breast cancer or ductal carcinoma in situ.
