Intraoperative Gamma Camera for Breast Cancer Surgery
France110 participantsStarted 2008-09
Plain-language summary
Aim: This study aims at evaluating the performances of an intraoperative gamma camera (field of view 10X10 cm), named CarolIReS, to detect axillary drainage and to assess the removal of sentinel lymph nodes (SLN) in breast surgery. Patients and Methods: SLN biopsy will be performed on 110 patients and the CarolIReS camera will be used preoperatively to localize SLNs. During surgery, individual removal of SLNs will be performed using a gamma probe named CarolIReS and their activity will be measured with a gamma ray counter. At the end of surgery, the CarolIReS camera will be used again to check the quality of surgery which will be followed by a surgical excision in case of remaining SLNs. Objectives: The main objective of this study is to evaluate the performances of the CarolIReS camera in assessing the axillary drainage of breast tumors and the surgical removal of SLNs. In addition, the possible correlation between the activity, the size, and the metastatic involvement of the SLNs will also be studied.Study hypothesis: Intraoperative cameras could be used to improve the efficiency of the SLN procedure

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Proportion of subjects for which the gamma camera can detect sentinel lymph nodes (SLN) not identified by other technic.
