NCT05445050

Brief Summary

The goal of this project is to adapt the super-resolution ultrasound imaging technology motion-model Ultrasound Localization Microscopy (mULM) to clinical application. In this exploratory patient study a scan protocol will be established to subsequently investigate whether mULM allows the assessment of the tumor response to neoadjuvant chemotherapy in participants with a primary breast cancer diagnosis as well as for the differentiation of benign and malignant breast tumors in participants with lesions of unknown dignity.

Outcome Measures

Primary Outcomes (4)

  • Relative blood volume

    Relative blood volume in % - describes the degree of vascularization - measured with mULM

    Study Part A & C: approximately 1 day before surgical removal of tumor

  • Blood flow

    Blood flow in mm/s - measured with mULM

    Study Part A & C: approximately 1 day before surgical removal of tumor

  • Change of relative blood volume

    Change of relative blood volume in %

    Study Part B: at the beginning of (approximately 1 hour before) first, second and fourth cycle of neoadjuvant chemotherapeutic treatment (each cycle is 14 days)

  • Change of blood flow

    Change of blood flow in mm/s

    Study Part B: at the beginning of (approximately 1 hour before) first, second and fourth cycle of neoadjuvant chemotherapeutic treatment (each cycle is 14 days)

Secondary Outcomes (1)

  • Change of tumor size

    Study Part B: at the beginning of (approximately 1 hour before) first, second and fourth cycle of neoadjuvant chemotherapeutic treatment (each cycle is 14 days)

Study Arms (1)

clinical application of mULM to support breast cancer diagnosis and therapy

OTHER

The study arm includes three parts A, B and C. In part A, the scan protocol, including the injection of the clinically approved contrast agent SonoVue® and the data acquisition time range, is optimized based on the mULM measurements of participants with primary breast cancer. The following part B consists of 2D-mULM measurements applied to triple-negative breast cancer patients throughout their neoadjuvant chemotherapy cycles with the aim to evaluate to which degree 2D-mULM allows for an assessment of the tumor response during therapy. In the last part C, participants with neoplasms of uncertain dignity will be investigated by 2D- and 3D-mULM measurements and the accuracy of differentiation between the lesions assessed.

Diagnostic Test: Application and measurement of tumor vascularization using diagnostic contrast enhanced ultrasound (CEUS)

Interventions

Part A: performing CEUS with the contrast agent SonoVue® at two different doses and two different injection speeds in participants with primary breast cancer Part B: performing CEUS with the contrast agent SonoVue® using the established protocol from part A in participants undergoing neoadjuvant chemotherapy Part C: performing CEUS with the contrast agent SonoVue® using the established protocol from part A in participants with lesions of unknown dignity
