About this study

Official title: Pilot Trial Evaluating a Miniature Radiofrequency Tag for Localization of Non-palpable Breast Lesions for Surgery

This pilot clinical trial studies radiofrequency technology in locating non-palpable breast lesions in patients undergoing surgery. Placing a miniature radiofrequency tag or microchip in the breast lesion before surgery and using a handheld device to guide doctors during surgery may improve surgical outcomes in patients with non-palpable breast lesions.

Read the detailed description

PRIMARY OBJECTIVES:

  1. Evaluate the feasibility of utilizing a new Federal Drug Administration (FDA)-cleared radiofrequency tag for localization of non-palpable breast lesions and provide preliminary data for a larger study.

OUTLINE:

Patients undergo mammogram or ultrasound for image-guided placement of the radiofrequency tag within 30 days of surgery and then undergo radiofrequency-guided localization during surgery.

After completion of study, patients are followed up within 2 weeks.

Being tested
Implanted Medical Device, Mammography, Questionnaire Administration, Radiofrequency (RFID) -Guided Localization, Ultrasonography
Medical subject headings
Breast Neoplasms

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Patients With Successful Placement of the Radiofrequency Tag Under Radiographic Guidance Confirmed by Mammography

    Patients with successful radiofrequency tag placement

    Measured: at time of device placement, confirmed by mammography

  2. Patients With Successful Retrieval of the Radiofrequency Tag Confirmed by Specimen Radiography

    Patients with successful radiofrequency tag retrieval.

    Measured: at time of surgery, within 30 days of tag implant

Secondary outcomes (8)
  1. Days Prior to Surgery of Insertion of Marker

    Mean number of days before surgery that radiofrequency tag was placed.

    Measured: Up to 30 days prior to surgery

  2. Patient Experience With Image-guided Placement of Tag as Rated by a Patient Questionnaire

    The patient experience with image-guided placement of the radio frequency Identification (RFID) tag.This assessments was captured using Likert-type questionnaires. Individual question responses for the patient and physician questionnaires ranged from 1 to 5 with the score of 5 representing the maximum positive or favorable response to each question. The following choices were included in each questionnaire:

    1. Strongly disagree
    2. Disagree
    3. Neutral
    4. Agree
    5. Strongly Agree

    Responses of the individual scales were added to create a total score, which would include a possible total range of 5 to a maximum of 25 points. 25 is the maximum positive or favorable response.

    Measured: within 24 hours of device placement

  3. Patients With Cancer Requiring Re-excision

    Patients requiring re-excision.

    Measured: up to 4 weeks post initial surgery

  4. Patients With Documented Migration of Marker

    Movement of radiofrequency tag from point of placement

    Measured: at time of surgery, within 30 days of tag implant

  5. Patients With Positive Margins on Initial Lumpectomy Using Radiofrequency Identification Technology

    Patients with margins of excisable tissue remaining.

    Measured: at time of pathologic evaluation of surgical specimen, within 4 weeks of surgery

  6. Radiologist's Experience Placing Radiofrequency Tag Compared to Wire Localization as Measured by a Radiologist's Questionnaire

    The radiologist's experience with image-guided placement of the RFID tag.This assessments was captured using Likert-type questionnaires. Individual question responses for the patient and physician questionnaires ranged from 1 to 5 with the score of 5 representing the maximum positive or favorable response to each question. The following choices were included in each questionnaire:

    1. Strongly disagree
    2. Disagree
    3. Neutral
    4. Agree
    5. Strongly Agree

    Responses of the individual scales were added to create a total score, which would include a possible total range of 5 to a maximum of 25 points. 25 is the maximum positive or favorable response.

    Measured: within 24 hours of device placement

  7. Surgeon's Experience Using Radiofrequency Tag to Guide Resection Compared to Wire Localization as Measured by a Surgeon's Questionnaire

    The surgeon's experience with image-guided placement of the RFID tag.This assessments was captured using Likert-type questionnaires. Individual question responses for the patient and physician questionnaires ranged from 1 to 5 with the score of 5 representing the maximum positive or favorable response to each question. The following choices were included in each questionnaire:

    1. Strongly disagree
    2. Disagree
    3. Neutral
    4. Agree
    5. Strongly Agree

    Responses of the individual scales were added to create a total score, which would include a possible total range of 5 to a maximum of 25 points. 25 is the maximum positive or favorable response.

    Measured: within 24 hours of surgery

  8. Volume (cm3), of Tissue Removed With Specimen With Tag (Not Including Shave Margins, if Taken)

    Amount of tissue removed with radiofrequency tag.

    Measured: at time of pathologic evaluation of surgical specimen, within 4 weeks of surgery

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Patients With Successful Placement of the Radiofrequency Tag Under Radiographic Guidance Confirmed by Mammography (time frame: at time of device placement, confirmed by mammography). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03202472, which also lists 1 linked publication.
