Background: This study was designed to compare radioguided versus routine wire localization of non palpable nonmalignant breast lesions in terms of efficacy for complete excision, ease of use, time saving, and cosmetic outcome. Materials and Methods: Patients with nonpalpable breast masses and nonmalignant core biopsy results who were candidates for complete surgical lumpectomy were enrolled and randomly assigned to radioguided or wire localization groups. Radiologic, surgical, and pathologic data were collected and analyzed to determine the difficulty and duration of each procedure, ease of use, accuracy, and cosmetic outcomes. Results: This prospective randomized study included 60 patients, randomly divided into wire guided localization (WGL) or radioguided occult lesion localization (ROLL) groups. The mean duration of localization under ultrasound guidance was shorter in the ROLL group (14.4 min) than in the WGL group (16.5 min) (p<0.001). The ROLL method was significantly easier for radiologists (p0.0001). The mean duration of the surgical procedure was 22.6 min (10.3 min) for ROLL and 23.6 min ( 9.6 min) for WGL (p0.6), a nonsignificant difference. Radiography of the surgical specimens showed 100% lesion excision with clear margins, as proved by pathologic examination, with both techniques. The surgical specimens were slightly heavier in the ROLL group, but the difference was not significant (p0.06). Conclusions: The ROLL technique provides effective, fast, and simple localization and excision of nonpalpable nonmalignant breast lesions.
