Overview
Brief Summary
This interventional, post-market, multicenter clinical investigation is designed to evaluate the performance of a custom-made medical device, "the Breast Cancer Locator (BCL)" in Subjects with non-palpable breast cancer, in Europe.
Detailed Description
The aim of this interventional, post-market, multicenter clinical investigation is to evaluate the performance of a custom-made medical device, the Breast Cancer Locator (BCL) system, in subjects with non-palpable breast cancer. The study will be conducted in European countries. To evaluate the performance of BCL in reducing the positive margin rate, the proportion of patients with positive margins after partial mastectomy with the BCL will be obtained. Each Subject, after signing an Informed Consent Form (ICF), will enter into a screening phase, during which several assessments (e.g., demographics, medical history, evaluation of available prone MRI and core biopsy pathological results) will be conducted. At visit 1, the Subject will undergo supine MRI, from which a 3D breast image and BCL will be made. At visit 2, the patient will undergo Breast Conserving Surgery (BCS) using the BCL system. On the same day, the specimen volume will be determined. The excised specimen will be sent to the pathological lab for analysis. The results, including the positive margin rate (PMR) and specimen mammogram, will be obtained within 14 days. At visit 3, follow-up assessments (including physical examination, and adverse event review) will be performed. At the End Of Study visit, adverse events will be assessed and patients will be asked to express their satisfaction with the BREAST-Q.
Investigators
Eligibility Criteria
Inclusion Criteria
- •Patient Informed consent form (ICF) signed
- •Female Aged ≥ 18 years at the time of the signature of ICF
- •Histologic diagnosis of IBC or DCIS
- •Tumor excision that will require localization because it cannot be definitively defined by palpation
- •The tumor is unifocal; possible satellite lesions \< 2 cm from primary are eligible
- •The tumor enhances and is greater than or equal to 5mm on prone breast MRI imaging
- •Subject and surgeon agree to perform BCS
- •Willingness to follow all study procedures, including attending all site visits, tests and examinations.
Exclusion Criteria
- •Absolute contraindication to MRI, including presence of implanted electrical device (e.g., pacemaker or neurostimulator), aneurysm clip, or metallic foreign body in or near eyes
- •Severe claustrophobia
- •Contraindication to use of gadolinium-based intravenous contrast, including life-threatening allergy
- •Uncontrolled cardiac, renal, or pulmonary disease
- •Uncontrolled systemic disease (e.g., lupus erythematosus or scleroderma)
- •Compromised renal function including chronic, severe kidney disease (GFR \< 30 ml/min/1.73m2), or acute kidney injury
- •Pregnancy or breast-feeding
- •Subjects who have received or plan to receive neoadjuvant chemotherapy
- •Sternal notch to nipple distance of \> 32 cm as measured in a sitting or standing position
- •Measurement of widest circumference around breasts and arms \> 135 cm
Outcomes
Primary Outcomes
Positive Margin Rate
Time Frame: Pathology results will from the index procedure be available within 14 days from the day of sample arrival at the pathological lab.
To evaluate the performance of BCL in reducing the positive margin rate, the proportion of patients with positive margins after partial mastectomy with the BCL will be obtained.
Secondary Outcomes
- Specimen volume(Results will be obtained the same day of surgery.)
- Adverse events(From supine MRI 10-40 days prior to surgery through 6 weeks +/- 7 days post surgery)
- Patient Satisfaction(6 weeks +/- 7 days post surgery)
- Surgeon's Perception(Results will be obtained prior to subject discharge after the study procedure (within approximately 2 days after surgery))
