The use of neoadjuvant systemic therapy in the treatment of breast cancer patients is increasing beyond the scope of locally advanced disease. Imaging provides important information in assessing response to therapy as a complement to conventional tumor measurements via physical examination. Tumor response to neoadjuvant therapy can also provide prognostic information. As stated in the background section, the attainment of pCR after completion of neoadjuvant therapy and surgical resection is associated with improved disease-free survival [1-3]. This correlation is especially strong for Triple-receptor negative (ER, PR negative and HER-2 non amplified), and HER-2 positive breast cancer. Studies of neoadjuvant therapy have used a variety of methods for assessing tumor response. Currently, there are no established clinical practice guidelines for how best to assess tumor response to neoadjuvant therapy. Typically, patients undergo conventional breast imaging (mammography and US) and physical examination, and DCE-MRI in selected cases.
The Imagio OA/US technology is an alternative imaging technology that demonstrates both gray scale ultrasound morphologic information, including size measurements, and functional information that includes presence or absence of tumor angiogenesis, degree of angiogenesis, and relative degrees of oxygenation and deoxygenation of hemoglobin.

- The number of masses that may exhibit qualitative changes in accordance with Functional Feature Scale as assessed by Imagio OA/US over the course of baseline though follow-up timepoints [ Time Frame: Baseline to Post Surgical Assessment at 6 months ]Feature scores per mass derived per Feature Score Scale (0-6 and 0-5 scoring- lower score mean most likely benign) per 5 mass features (External Peripheral Zone, External Capsular Boundary, Internal Shape, Internal Echotexture, Internal Sound ) used to predict number of masses that demonstrated response or no response at all time points (baseline, cycle 2, mid cycle and pre surgical) to chemotherapy treatment
- Number of masses that correlate with chemotherapy response/no response as assessed by Functional Feature Score Scale at all study timepoints to predict optimal timing for Imagio imaging [ Time Frame: Baseline to Post Surgical Assessment at 6 months ]Number of masses assessed at baseline and follow-up timepoints - cycle 2, mid cycle and pre surgical f/u that correlate with feature score (External Peripheral Zone, External Capsular, Internal Vessel Score, Internal Total Hemoglobin, Internal Deoxygenated Blush) changes assessed by Feature Score Scale (0-6 nd 0-5 scores depending on feature) and pathologic complete response (pCR) to determine optimal timing for imaging.
- Number of metastatic lymph nodes scored using a Lymph Node Scoring Scale that may correlate with chemotherapy response [ Time Frame: Baseline to Post Surgical Assessment at 6 months ]Imagio OA/US imaging of metastatic lymph nodes will be assessed using a designated Lymph Node Scale (Shape Score, Cortical Thickness, Margin Score and Hilar Compression Score, Size Score) to predict response(0 = benign / 1 = benign, uncertain / 2-4 = probably malignant / >=5 = malignant) to chemotherapy
