  • Adverse Events [ Time Frame: 5 weeks post treatment ]
    To evaluate the incidence and severity of the ExAblate MRgFUS device-related complications to establish the safety profile of the ExAblate ablation of breast cancer visible on contrast-enhanced MRI with 5-10 mm margins around the primary tumor
  • Histopathological analyses [ Time Frame: 5 weeks post treatment ]
    To estimate the effectiveness of ExAblate MRgFUS to ablate 100% of an up-to-2-cm breast cancer visible on an contrast-enhanced MRI with 5-10 mm margins around the primary tumor.

Descriptive Information
Brief Title  ICMJE Study of ExAblate Focused Ultrasound Ablation of Breast Cancer
Official Title  ICMJE Study of ExAblate Focused Ultrasound Ablation of Breast Cancer Under MR Guidance (MRgFUS) and MRI Evaluation of Ablation
Brief Summary

The goal of this prospective, non-randomized, single-arm, multi site, international study is to develop data to evaluate the safety and effectiveness of the ExAblate MRgFUS system in the ablation of breast cancer and of MRI.

The goal of MRgFUS ablation of breast cancer is to plan and ablate the entire tumor volume in a treatable and device accessible location.

Detailed Description In this international, non-randomized, single-arm study, a total of 200 patients with a positive diagnosis of invasive breast cancer with a scheduled surgical resection will be enrolled into the trial. Eligible participants will be evaluated and treated with ExAblate breast ablation prior to their planned definitive surgical treatment. After the 10 to 21 days post ExAblate therapy, study participants will have another contrast-enhanced MR imaging examination. Their planned tumor excision will then be completed no later than 14 days from the contrast-enhanced, post ExAblate procedure MR imaging examination. Additionally, the end points of the study will be compared against the CORE Pathology Lab results.
