- Brief Summary
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.
- Detailed Description
PRIMARY OBJECTIVES:
I. 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.

Group Intervention Description Diagnostic (radiofrequency-guided localization) Mammography 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. Diagnostic (radiofrequency-guided localization) Radiofrequency (RFID) -Guided Localization 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. Diagnostic (radiofrequency-guided localization) Implanted Medical Device 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. Diagnostic (radiofrequency-guided localization) Questionnaire Administration 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. Diagnostic (radiofrequency-guided localization) Ultrasonography 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.
- Primary Outcome Measures
Name Time Method Patients With Successful Placement of the Radiofrequency Tag Under Radiographic Guidance Confirmed by Mammography at time of device placement, confirmed by mammography Patients with successful radiofrequency tag placement
Patients With Successful Retrieval of the Radiofrequency Tag Confirmed by Specimen Radiography at time of surgery, within 30 days of tag implant Patients with successful radiofrequency tag retrieval.
- Secondary Outcome Measures
Name Time Method Patients With Positive Margins on Initial Lumpectomy Using Radiofrequency Identification Technology at time of pathologic evaluation of surgical specimen, within 4 weeks of surgery Patients with margins of excisable tissue remaining.
Days Prior to Surgery of Insertion of Marker Up to 30 days prior to surgery Mean number of days before surgery that radiofrequency tag was placed.
Patients With Cancer Requiring Re-excision up to 4 weeks post initial surgery Patients requiring re-excision.
Patients With Documented Migration of Marker at time of surgery, within 30 days of tag implant Movement of radiofrequency tag from point of placement
Radiologist's Experience Placing Radiofrequency Tag Compared to Wire Localization as Measured by a Radiologist's Questionnaire within 24 hours of device placement 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.Surgeon's Experience Using Radiofrequency Tag to Guide Resection Compared to Wire Localization as Measured by a Surgeon's Questionnaire within 24 hours of surgery 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:
