Ultrasound and Chemotherapy of Breast Cancer: Relationship Between Early Vascular Changes of the Tumor and Late Tumoral Response
Contrast-Enhanced Ultrasound and Neoadjuvant Chemotherapy of Breast Cancer: Relationship Between Early Vascular Changes of the Tumor and Late Tumoral Response
This study intends to assess the ability of contrast-enhanced ultrasound to make the efficacy of chemotherapy in breast cancer precise.
This real-time noninvasive and feasible imaging technique allows us, the investigators at University Hospital Tours, to evaluate early vascular changes of breast tumors during treatment. These vascular changes may precede long-term tumoral regression. Imaging of primary breast lesions may be of value in the prediction of late treatment response.
An ultrasound will be performed before the initiation, and after the second and the last dose of chemotherapy.
To investigate the changes occurring in the vascularization of tumors, we will use an intravascular ultrasound contrast agent SonoVue (sulphur hexafluoride microbubbles).
This agent is a microbubbles preparation that is stable, resistant to pressure, and specifically designed to be used as a contrast agent for ultrasound imaging of angiogenesis.
