DWI in Assessing Treatment Response in Patients With Breast Cancer Receiving Neoadjuvant Chemotherapy (ACRIN6698)
RATIONALE: Imaging procedures, such as diffusion-weighted magnetic resonance imaging (DWI) and dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI), may help in evaluating how well patients with breast cancer respond to treatment.
PURPOSE: This research trial studies DWI and DCE-MRI in assessing treatment response in patients with breast cancer undergoing neoadjuvant chemotherapy.

- Pathologic complete response (pCR) [ Time Frame: Until surgery ]
- Change in ADC value as measured by area under the receiver operating characteristic curve from each treatment timepoint to baseline [ Time Frame: Until surgery ]
- Changes in ADC value, DCE-MRI tumor volume, and SER [ Time Frame: Until surgery ]
- Effectiveness of the individual measurement's changes in ADC value, DCE-MRI tumor volume, and SER [ Time Frame: Until surgery ]
- Test-retest reproducibility of DW-MRI ADC metric [ Time Frame: Pre-treatment MRI ]

Experimental: Diffusion Weighted-MRI
Participants on all arms of the I-SPY II trial will undergo diffusion-weighted magnetic resonance imaging as described in the ACRIN 6698 protocol. The experimental component/intervention is whether DW-MRI can predict therapeutic response in neoadjuvant treatment for breast cancer.
Procedure: diffusion-weighted magnetic resonance imaging
diffusion-weighted magnetic resonance imaging examination and subsequent radiologist interpretation
- To determine if the change in tumor apparent diffusion coefficient (ADC) value measured from each treatment timepoint to baseline is predictive of pathologic complete response (pCR).
- To determine if the combined measurement of change in tumor ADC value, change in tumor volume, and change in peak signal-enhancement ratio (SER) is predictive of pCR.
- To investigate the relative effectiveness of the individual measurements, change in tumor ADC value, change in tumor volume, and change in peak SER for predicting pCR in experimental treatment arms.
- To assess the test-retest reproducibility of ADC metrics applied to breast tumors.
OUTLINE: This is a multicenter study.
Patients undergo diffusion-weighted magnetic resonance imaging (DWI) at baseline, after week 3 of neoadjuvant paclitaxel regimen, and prior to and after completion of 4 courses of neoadjuvant chemotherapy. Patients then undergo surgery. Patients undergo DWI prior to contrast administration for dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI).
After completion of treatment procedure, patients are followed up for 5 years on the I-SPY 2 TRIAL.
