Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Pathologic Response Based on Miller-Payne Grading System | Up 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) |

Participant flow
Pre-assignment details
An additional arm (NIR/US - Crossover from Endocrine Cohort to Chemotherapy Cohort) was added for results reporting as one participant transitioned from the Endocrine Cohort to the Chemotherapy Cohort because the participant's therapy was changed mid-treatment from Endocrine to Chemotherapy.
Participants by arm
| Arm | Count |
|---|---|
| NIR/US (Neoadjuvant Chemotherapy Cohort) Patients 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 | 39 |
| NIR/US (Neoadjuvant Endocrine Cohort) Patients 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 | 1 |
| NIR/US (Crossover From Endocrine Cohort to Chemotherapy Cohort) Patients 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 | 1 |

Outcome results
Pathologic Response Based on Miller-Payne Grading System
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)
Time frame: Up to 6 months
Population: For this outcome measure, the one participant who was in the crossover cohort was counted in the neoadjuvant chemotherapy cohort. Three participants in the neoadjuvant chemotherapy cohort were not evaluable for this outcome measure (2 developed metastases prior to completing neoadjuvant therapy and 1 was taken off study after first imaging appointment).
