Breast Elasticity Imaging During Neoadjuvant Chemotherapy
What this study is about
For this study, the investigators propose investigation of a new imaging technique, Harmonic Motion Imaging (HMI), and the evaluation of its potential role in prediction of breast cancer response to neoadjuvant chemotherapy (NACT). The investigators hypothesize that changes in HMI parameters will predict response to neoadjuvant systemic therapy in early-stage breast cancer.

For this study, the investigators propose investigation of a new imaging technique, Harmonic Motion Imaging (HMI), and the evaluation of its potential role in prediction of breast cancer response to neoadjuvant chemotherapy (NACT). The investigators hypothesize that changes in HMI parameters will predict response to neoadjuvant systemic therapy in early-stage breast cancer.
Interventions
PROCEDURE
Harmonic motion imaging
Harmonic motion imaging (HMI) is a non-invasive ultrasound elasticity imaging technique that yields a quantitative relative measurement of tissue stiffness suitable for comparisons between individuals and over time. This technique induces dynamic tissue vibrations internally for tissue elasticity characterization. Participants will be asked to lie down on their back, hold still with shallow breathing while pictures/images are taken of the breast where the tumor is located using an ultrasound without any invasive procedures.
Primary outcome measures
Assessment of the correlation between change in HMI measurements and pathologic response at completion of neoadjuvant therapy
Time frame: Baseline and through neoadjuvant therapy completion (an average of 28 weeks)
* Repeated measures analysis of variance (ANOVA) will be performed to investigate the overall differences in HMI measurements within the tumor and surrounding tissue between responders (pCR and RCB1) and non-responders (RCB2). This relative percent change in tumor stiffness is directly related to HMI measurements. * Pathologic response will be assessed by the Residual Cancer Burden (RCB) score, a continuous and categorical measure of pathologic response and an independent predictor of disease free survival. Pathologic response will be dichotomized, with response defined as a score of 0-1 (RCB\<2), and no response defined as a score of 2-3 (RCB2).
Assessment of the correlation between change in HMI measurements and pathologic response during neoadjuvant systemic therapy
Time frame: Baseline and during short-interval on treatment (approximately 4 weeks after treatment initiation)
* Repeated measures analysis of variance (ANOVA) will be performed to investigate the overall differences in HMI measurements within the tumor and surrounding tissue between responders (pCR and RCB1) and non-responders (RCB2). This relative percent change in tumor stiffness is directly related to HMI measurements. * Pathologic response will be assessed by the Residual Cancer Burden (RCB) score, a continuous and categorical measure of pathologic response and an independent predictor of disease free survival. Pathologic response will be dichotomized, with response defined as a score of 0-1 (RCB\<2), and no response defined as a score of 2-3 (RCB2).

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
