Summary

MAGNETO is a French medico-economic study on preoperative localization in breast cancer surgery. The main objective is to conduct a cost-consequence analysis comparing magnetic clip localization with the use of metallic wires for the preoperative identification of non-palpable breast lesions. The choice of localization method is left to the physician's and center's discretion. The study is non-interventional (with only questionnaires and data collection), prospective, and multicenter, with patient follow-up lasting up to six months after breast surgery.

Plain Language Summary

Simplified for easier understanding

This study is evaluating the cost-effectiveness of using a magnetic seed (a small implant placed before surgery) to precisely locate a breast tumor during surgery in France, compared to other localization methods — assessing whether the technology is worth adopting more widely. **You may be eligible if...** - You are a woman 18 years or older - You have a single, one-sided breast lesion (invasive carcinoma or ductal carcinoma in situ) - You need breast-conserving surgery and preoperative tumor localization - You are affiliated with a French health insurance system - You do not object to participating in the study **You may NOT be eligible if...** - You need surgery on both breasts - Your breast cancer has spread to other organs (metastatic) - You have multiple tumors or a benign lesion - You are pregnant or breastfeeding - You need neoadjuvant (pre-surgery) treatment first - You are under legal guardianship Talk to your doctor to see if this trial is right for you.
