Wire-guided Localization in Non-palpable Breast Cancer: Results from Monocentric Experience

Breast-conserving surgery (BCS) is considered the gold-standard treatment for early breast cancer. Ultrasound-guided percutaneous biopsy or stereotactic biopsy of a breast lesion allows preoperative histological diagnosis. Various techniques have been proposed for identifying non-palpable breast tumors, but the most popular method is the wire-guided localization (WGL) technique. The aim of this study was to propose an alternative technique for optimizing the WGL procedure, facilitating breast surgery and reducing complications.

We performed a prospective study on 40 patients with a single non-palpable breast lesion. For the preoperative localization of mammary lesions, patients were divided randomly into two groups: 20 patients underwent conventional WGL technique and 20 underwent 'optimized' personalized technique.

In the group treated with the optimized technique, dislocation of the wire occurred in only 2/20 cases, whereas in those with the conventional technique, dislocation occurred in 9/20 cases (p=0.03). In 5/20 cases of the conventional WGL technique, the wire was accidentally cut by the surgeon, whereas no similar complications were observed in the group that underwent the optimized technique (p=0.047). Re-excision of the surgical margins was necessary in 6/20 cases with the conventional technique, while re-excision was not required for any case using the optimized technique (p=0.02).

The proposed optimized technique ensures good esthetic results, enabling the surgeon to identify the lesion and perform oncoplastic breast surgery, and allows surgical time to be reduced.
