Use of the ROLL technique for lumpectomy in non-palpable breast lesions.

Objective: To evaluate the efficiency of radioguided occult lesion localising in non-palpable breast lesions (NPBL) compared to the surgical wire technique.

Method: A prospective study was conducted on 161 women with NPBL, of whom 80 marked with the wire (group 1), whereas 81 women were marked with an intratumour injection of Tc-nanocoloid (group 2). The NPBL were located by ultrasound or stereotactic guidance.
