Experimental: HER2-targeted PET/CT
Pts with confirmed HER2- breast cancer will then undergo HER2-targeted PET/CT.
89Zr-trastuzumab is a novel radiotracer which allows excellent visualization of HER2+ lesions.
89Zr-pertuzumab is a novel radiotracer which may allow for specific visualization of HER2+ lesions.
PET/CT imaging with these novel radiotracers will allow evaluation of all identifiable malignant lesions, rather than evaluation of only single lesions by biopsy.
Avid lesions will be considered suspicious for HER2+ malignancy.
Pts with at least one 89Zr-trastuzumab or 89Zr-pertuzumab avid lesion will be biopsied to confirm HER2+ pathology.
From these 50 pts, we will determine the proportion of HER2- primary breast cancer pts that express HER2+ malignancy imagable by HER2-targeted PET/CT.
Pts recruited to the protocol, but then drop out prior to HER2-targeted PET/CT due HER2+ disease being identified on retesting of the patient's archived tissue samples, will be replaced with newly recruited pts.

Percentage of Patients With HER2- Primary Breast Cancer Who Develop Imagable HER2+ Metastases
Time Frame: 3 years

Both SUVmax and SUVpeak will be recorded for lesions, and SUVmax and SUVaverage will be recorded for background measurements.
Only those foci qualitatively scored conspicuously positive by both readers (scores of 4 or 5) will be considered as "positive".
