简要总结
The objective of this clinical trial is to demonstrate the reduction of positive margins in the definitive pathology of patients undergoing breast-conserving surgery with the systematic shaving technique compared to conventional surgery, and the reduction of second interventions for margin enlargement.
详细描述
Patients with breast cancer who undergo breast-conserving surgery are randomized in the operating room after lumpectomy into 2 groups of 117 patients each: shaving/no-shaving (standard surgery).
