GroupInterventionDescription
NIR/US (Neoadjuvant Chemotherapy Cohort)Optical Tomography Using Near Infrared Diffused Light Assisted with UltrasoundPatients will have the NIR/US baseline scan performed before their first treatment. The desirable schedule will be \>= 7 days after initial biopsy to avoid confounding effects from the biopsy related acute inflammatory response. * In addition, patients will also have NIR/US performed at end of cycle 1, end of cycle 2, end of cycle 3, end of cycle 5 (only if treatment regimen changed), and prior to surgery. * The number of NIR/US study visits may vary (5-6) depending on the patient's treatment regimen
NIR/US (Neoadjuvant Endocrine Cohort)Optical Tomography Using Near Infrared Diffused Light Assisted with UltrasoundPatients will have the NIR/US baseline scan performed before their first treatment. The desirable schedule will be \>= 7 days after initial biopsy to avoid confounding effects from the biopsy related acute inflammatory response. * In addition, patients will also have NIR/US performed at end of cycle 1, end of cycle 2, end of cycle 3, at time of treatment regimen change (only intended for those who have had a change in their regimen), and prior to surgery. * The number of NIR/US study visits may vary (5-6) depending on the patient's treatment regimen
Primary Outcome Measures
NameTimeMethod
Pathologic Response Based on Miller-Payne Grading SystemUp to 6 months

In the Miller-Payne system, the pathologic response is divided into 5 grades based on comparison of tumor cellularity between pre-neoadjuvant core biopsy and definitive surgical specimen as:

* grade 1: no change or some alteration to individual malignant cells but no reduction in overall cellularity (pNR)

* grade 2: a minor loss of tumor cells but overall cellularity still high; up to 30% (pPR)

* grade 3: between an estimated 30% and 90% reduction in tumor cells (pPR)

* grade 4: a marked disappearance of tumor cells such that only small clusters or widely dispersed individual cells remain (almost pCR); more than 90% loss of tumor cells

* grade 5: no malignant cells identifiable in sections from the site of the tumor; only vascular fibroelastonic stroma remains often containing macrophages (pCR) (however, ductal carcinoma in situ (DCIS) may be present)
