Breast VCEUS to Evaluate Early Response to Neoadjuvant Chemotherapy
- Conditions
- Breast Cancer
- Interventions
- Diagnostic Test: 2D US grayscale plus quantitative VCEUS
- Registration Number
- NCT01817374
- Lead Sponsor
- University of Alabama at Birmingham
- Brief Summary
1. Evaluate quantitative VCEUS imaging for determining early breast cancer response to neoadjuvant chemotherapy and compare results to co-temporal volume change on grayscale ultrasound and post-treatment mammography findings utilizing final surgical pathology and clinical outcome.
2. Assess incremental benefit of quantitative VCEUS to planar CEUS tumor perfusion measurements and enhancement patterns in predicting tumor response to adjuvant treatment in clinical studies.
The contrast agent Definity® is FDA approved for use as a contrast agent during ultrasound (echocardiography) of the heart. Definity® will be used "off-label" (during ultrasound of the breast) in this study. The administration of Definity® during this study will follow total dose guidelines approved by the FDA.

Group Intervention Description 2D US grayscale plus quantitative VCEUS 2D US grayscale plus quantitative VCEUS Patients with breast cancer receiving neoadjuvant chemotherapy will undergo a 2D grayscale imaging followed by quantitative VCEUS imaging: 1. prior to initiation of treatment (baseline); 2. at 14 (± 4 days) after initiation of neoadjuvant chemotherapy (early treatment); 3. at 28 days (± 4 days) after initiation of neoadjuvant chemotherapy (inter-regimen); 4. at completion of therapy prior to definitive surgery (usually 2-3 months after initiation of treatment). Each patient will undergo a total of four VCEUS examinations.
- Primary Outcome Measures
