Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

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

  • 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)

  • 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
  • Known allergy to device components
  • Multicentric tumors (additional tumors > 2 cm from primary)
  • Infectious or inflammatory processes near the area of intervention
  • Planned surgery with localization devices including WGL, intraoperative ultrasound guidance, radiofrequency emitting implants, magnetic seeds, radioactive seeds, and tissue inspection devices
  • Simultaneous participation in an interventional study or participation in an interventional study in the last 1 month before study inclusion

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Treatment with BCL
Subjects will undergo breast conserving surgery with the Breast Cancer Locator (BCL)
Device: Breast Cancer Locator Guided Breast Conserving Surgery
Subjects will undergo a contrast-enhanced supine MRI and two marks will be placed on the breast. The MRI images will be transmitted to the sponsor, and the images will be used to build a BCL using 3D printing. Investigators will be provided with a 3D image of the cancer in the breast. Investigators will use a BCL (a patient-specific, plastic, bra-like form that is placed on the breast and allows the investigator to mark the edges of the tumor on the skin and to place wires inside the breast which define the center of the cancer and the tumor edges. The surgeon will then attempt to surgically remove all the tissue inside the wires used to define the tumor edges.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Positive Margin Rate
Time Frame: Pathology results from the index procedure 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 was obtained.
Pathology results from the index procedure available within 14 days from the day of sample arrival at the pathological lab.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Surgeon's Perception
Time Frame: Results will be obtained prior to subject discharge after the study procedure (within approximately 2 days after surgery)
To evaluate the surgeon's perception of the BCL system, a survey asking them if they strongly disagree, somewhat disagree, are undecided, somewhat agree, or strongly agree that the BCL made tumor localization easier, was easy to use, made tumor excision easier, and would be recommended by them, will be used.
Results will be obtained prior to subject discharge after the study procedure (within approximately 2 days after surgery)
Specimen Volume
Time Frame: Results obtained the same day of surgery.
To calculate the specimen volume after BCL guided partial mastectomy, the water displacement method (WDM) was used.
Results obtained the same day of surgery.
Number of Participants With Adverse Events
Time Frame: From supine MRI 10-40 days prior to surgery through 6 weeks +/- 7 days post surgery
To evaluate the safety and tolerability of BCL, adverse events will be reported, including frequency, maximum intensity, relation to study treatment, seriousness, action taken, and outcome. Safety data will be handled descriptively.
From supine MRI 10-40 days prior to surgery through 6 weeks +/- 7 days post surgery
Patient Satisfaction
Time Frame: 6 weeks +/- 7 days post surgery
To evaluate the patient's satisfaction, the BREAST-Q patient-reported outcome measure will be used. Patient satisfaction scores range from 0-100, with a higher score meaning greater satisfaction or better quality of life.
6 weeks +/- 7 days post surgery
