Efficacy of Magnetic Resonance-guided High Intensity Focused Ultrasound for the Ablation of Breast Cancer

Brief Summary

The purpose of the study is to evaluate the efficacy of a dedicated Magnetic Resonance guided High Intensity Focused Ultrasound (MR-HIFU) unit in ablating breast cancer by comparing MR imaging and pathologic specimen after resection. Single-center, single-arm, non-randomized trial

Intervention / Treatment

  • Philips Sonalleve® MR-HIFU Breast Therapy System (DEVICE)
    The breast tumor lesion of qualified study patients will be treated with MR-HIFU under procedural sedation with Propofol and Ketamine.

    The dedicated MR-HIFU unit has been shown to be safe and feasible to ablate breast tissue.

    The planned study should address the possibility to completely ablate breast cancer with the dedicated breast MR-HIFU unit. The result of the MR-HIFU therapy should be monitored by imaging (contrast enhanced MRI) as well as with histopathological correlation after surgery.

    The patient population would consist of female patients with proven breast cancer scheduled for surgical lumpectomy or mastectomy.

    The idea is to evaluate a minimal invasive method to treat breast cancer as a potential alternative to surgical resection in the future

    Participant Groups

    • Patients with breast cancer and scheduled surgical resection (lumpectomy or mastectomy) will be treated with Philips Sonalleve® MR-HIFU Breast Therapy System prior to surgery in a treat\& resect model

    Eligibility Criteria

    Sex: Female
    Minimum Age: 18
    Age Groups: Adult / Older Adult
    Healthy Volunteers: Yes

    Inclusion Criteria:

    * Informed Consent as documented by signature
    * World Health Organization (WHO) performance status≤ 2
    * Body weight ≤ 80 kg
    * Biopsy proven invasive breast cancer with a size of ≤3.0cm (TNM classification: cT1-2 N0-2 MX ).
    * Histological type of tumor: invasive ductal carcinoma (IDC)
    * Patient is scheduled for surgical resection of tumor at study site
    * Tumor location within the reach of the HIFU transducers with the patient in prone position; distance from skin and pectoral muscle to the tumor ≥ 1.0 cm.
    * Target breast fits in the cup of the dedicated MR-HIFU breast system

    Exclusion Criteria:

    * neoadjuvant systemic therapy
    * prior radiotherapy in target breast
    * contraindications for MRI
    * contraindication for application of gadolinium-based contrast agent
    * contraindication for procedural sedation analgesia
    * macro-calcifications in or around the targeted tumor
    * scar tissue or surgical clips in the direct path of the ultrasound beams
    * Women who are pregnant or breast feeding,
    * Intention to become pregnant during the course of the study,
    * Lack of safe contraception, defined as: Female participants of childbearing potential, not using and not willing to continue using a medically reliable method of contraception for the entire study duration, such as oral, injectable, or implantable contraceptives, or intrauterine contraceptive devices, or who are not using any other method considered sufficiently reliable by the investigator in individual cases.
    * Known or suspected non-compliance, drug or alcohol abuse,
    * Inability to follow the procedures of the study, e.g. due to language problems, psychological disorders, dementia, etc. of the participant,
    * Participation in another study with investigational drug/device within the 30 days preceding and during the present study,
    * Previous enrolment into the current study

    Primary Outcomes
    • Quantitative assessment: Correlation between MRI and histopathology results (volume of necrosis)

    Secondary Outcomes
    • Effective treatment is defined as complete necrosis (100%) of targeted tumor including safety margin (\>1mm) (histopathological analysis). Safety margin: measurement of smallest margin on histology and measurement of smallest margin on MRI. Parameter: Percentage of necrosis including safety margin

    Other Outcomes
    • Adverse events, general: Patients will be asked to report information about adverse events at each time point of the study. Information about time of onset, duration, resolution, action to be taken assessment of intensity, relationship with study treatment will be collected. Assessment of additional predefined safety parameters: - Skin changes, assessment in physical examination: presence/absence of redness, burn * Palpation breast: lump (mobility of lump related to skin: yes/no) * Pain, reported by patient
