Novel MRI-Guided Ultrasound Stimulated Microbubble Radiation Treatment for Patients With Chest-wall and Locally-Advanced Breast Cancer

Sommaire:

Cette étude vise à démontrer la faisabilité d’un nouveau traitement par microbulles stimulées par ultrasons guidé par l’IRM pour accroître les effets de la radiation chez les personnes qui reçoivent une radiothérapie externe administrée par un dispositif de radiothérapie LINAC (accélérateur linéaire).

Description de l'essai

Primary Outcome:

  • Incidence of toxicity and adverse events using MRg-FUS+MB treatment in patients with chest-wall and locally advanced breast cancer
Secondary Outcome:
  • Radiological Response
The objective of this study is to demonstrate the feasibility of novel MRI-guided ultrasound stimulated microbubble treatment to enhance radiation effects in humans receiving external beam radiation therapy delivered using a LINAC (linear accelerator) radiation therapy device. The investigators have previously demonstrated that ultrasound and microbubble mediated endothelial cell perturbation can significantly enhance the effectiveness of radiation. It enhances tumour response to radiation significantly by synergistically destroying tumour blood vessels. The technique is targeted spatially and achieves tumour specificity by confining the low-power ultrasonic fields that stimulate microbubbles to the tumour location only. By perturbing the tumour vasculature and activating specific genetic pathways, the technique sensitizes the targeted tissues to the subsequent therapeutic application of radiation, resulting in significantly enhanced cell killing. The primary aim of this research is to evaluate the safety profile of MRI-guided ultrasound stimulated microbubble treatment and radiation in patients with chest wall and breast cancer. The secondary aim is to evaluate tumour (primary and/or nodal) response to MRg-FU + MB and radiation, as measured radiologically within the treated therapeutic regions.
