What this trial studies

This study aims to evaluate the feasibility of using quantitative ultrasound to guide adaptive neoadjuvant chemotherapy in women with breast cancer. It will compare the effectiveness of this ultrasound-guided approach against standard clinical monitoring and therapy. By detecting cell death early in the treatment process, the study seeks to enable timely adjustments to chemotherapy regimens, potentially leading to better patient outcomes. A total of 240 patients will be randomized to assess the safety and efficacy of this innovative method.

Who should consider this trial

Good fit: Ideal candidates for this study are women aged 18 and older with a diagnosis of breast cancer and a primary tumor larger than 2 cm who are eligible for neoadjuvant chemotherapy.

Not a fit: Patients with inflammatory breast cancer or those with contraindications to neoadjuvant treatment, such as pregnancy or severe comorbidities, may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to more effective chemotherapy treatments for breast cancer patients by allowing for quicker adjustments based on treatment response.

How similar studies have performed: While the use of ultrasound in monitoring treatment response is established, this specific approach of guiding chemotherapy based on quantitative ultrasound is novel and has not been extensively tested in prior studies.
