I. To evaluate the standardized uptake value maximum (SUVmax) in patients with previously untreated HER2+ breast cancer.
I. To evaluate if the uptake of copper 64 Cu-64-DOTA-trastuzumab, a proposed indicator of responsiveness to HER2-directed therapy, correlates with serpin peptidase inhibitor alpha-1 antiproteinase, antitrypsin, member 1 gene (SERPINA1) expression, which has been shown to be associated with estrogen receptor positive (ER+)/ HER2+ patient survival, both in the HER2+/ER+ patients and in all patients.
II. To compare uptake of copper Cu 64-DOTA-trastuzumab in the patients with complete pathologic response (pCR) vs. non-pCR patients.
Patients receive trastuzumab intravenously (IV) over 15 minutes immediately before receiving copper Cu 64-DOTA-trastuzumab IV on day 0. Patients undergo PET scans at 18-24 and 42-48 hours, on day 1 and 2. Within 4 days after completion of PET scans, patients then receive trastuzumab IV over 30-90 minutes weekly or every 3 weeks and pertuzumab IV over 30-60 minutes. Treatment repeats every 21 days for 6 courses in the absence of disease progression or unacceptable toxicity. Patients undergo surgery after 6 courses of trastuzumab and pertuzumab.
After completion of study treatment, patients are followed up for 1 year.

Experimental: Treatment (trastuzumab, copper Cu 64-DOTA-trastuzumab PET)
Patients receive trastuzumab IV over 15 minutes immediately before receiving copper Cu 64-DOTA-trastuzumab IV on day 0. Patients undergo PET scans at 18-24 and 42-48 hours, on day 1 and day 2. Within 4 days after completion of PET scans, patients receive trastuzumab IV over 30-90 minutes weekly or every 3 weeks and pertuzumab IV over 30-60 minutes. Treatment repeats every 21 days for 6 courses in the absence of disease progression or unacceptable toxicity. Patients undergo surgery after 6 courses of trastuzumab and pertuzumab.
