Anatomic Stage III Breast Cancer AJCC v8, Locally Advanced Breast Carcinoma
Conditions
Brief summary
This phase II/III trial studies if contrast-enhanced ultrasounds using a contrast dye, perflutren lipid microspheres (Definity), can predict the response to chemotherapy by estimating the pressure in the cancer in patients with breast cancer that has spread to nearby tissues and lymph nodes (locally advanced). The efficacy of cancer therapy is affected by the pressure in the cancer. Definity is a contrast dye used to create better images during ultrasounds. The purpose of this trial is to determine if a special kind of ultrasound, called contrast-enhanced ultrasound, an experimental imaging test, can detect pressures in cancer to determine the response to neoadjuvant chemotherapy in patients with breast cancer.
Detailed description
PRIMARY OBJECTIVE: I. To apply and evaluate a novel biomarker from 3-dimensional subharmonic aided pressure estimation (3D SHAPE) to predict neoadjuvant chemotherapy (NAC) response in patients with breast cancer. SECONDARY OBJECTIVE: I. To assess whether the accuracy of 3D SHAPE for predicting locally advanced breast cancer (LABC) NAC response varies with breast cancer subtype. OUTLINE: Patients undergo contrast-enhanced ultrasound (CEUS) and receive perflutren lipid microspheres intravenously (IV) over 10-15 minutes before NAC, after 10% of NAC, and after 30% of NAC. Patients also undergo unenhanced baseline ultrasound imaging before NAC, after 10% of NAC, after 30% of NAC, and after 100% of NAC. After completion of study, patients are followed up at the completion of NAC.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Calculation of tumor volume changes with neoadjuvant chemotherapy (NAC) | Up to study completion (48 months) | 3-dimensional (3D) tumor measurements over the three ultrasound exams will be recorded for each subject to calculate tumor volume changes with NAC. The tumor volume change during the therapy will be compared to imaging (magnetic resonance imaging or ultrasound) and pathologic response as well as to the corresponding 3D subharmonic aided pressure estimation (SHAPE) results. |
| Prediction of the patients' clinical and pathological response | Up to study completion (48 months) | The SHAPE results from three time points (i.e. before, 10% completion, and 30% completion of NAC) will be modeled for predicting the patients' clinical response as well as pathological response using longitudinal logistic regression with adjustment for correlated observations over time by generalized linear mixed effects or generalized estimating equations (GEE) modeling. |
| The ability of the SHAPE method to distinguish responders from non-responders | Up to study completion (48 months) | Will also be compared using receiver operating characteristic analysis to develop thresholds for decision-making based on balancing sensitivity and specificity. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Accuracy of the 3D SHAPE for predicting locally advanced breast cancer NAC response varies with breast cancer subtype | Up to study completion (48 months) | The variation of the accuracies of the SHAPE results by breast cancer subtypes will be reported. The generalized linear mixed effects or GEE modeling will be stratified by breast cancer subtype and also extended to include modeling of breast cancer subtype as a main effect and as an interaction effect with SHAPE. |
