NCT04715958

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.

Outcome Measures

Primary Outcomes (3)

  • Calculation of tumor volume changes with neoadjuvant chemotherapy (NAC)

    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.

    Up to study completion (48 months)

  • Prediction of the patients' clinical and pathological response

    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.

    Up to study completion (48 months)

  • The ability of the SHAPE method to distinguish responders from non-responders

    Will also be compared using receiver operating characteristic analysis to develop thresholds for decision-making based on balancing sensitivity and specificity.

    Up to study completion (48 months)

Secondary Outcomes (1)

  • Accuracy of the 3D SHAPE for predicting locally advanced breast cancer NAC response varies with breast cancer subtype

    Up to study completion (48 months)

Study Arms (1)

Diagnostic (CEUS, Definity)

EXPERIMENTAL

Patients undergo CEUS and receive perflutren lipid microspheres 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
