Comparison of wire-guided localization (WGL) and radio-guided occult lesion localization(ROLL) in localization of non-palpable breast lesions

Abstract

Abstract Background: The number of patients with non-palpable breast lesions has increased gradually. This is because of the technological development in imaging techniques and the screening programs that lead to early detection of breast lesions. The aim of marking the non-palpable breast lesions is to achieve accurate lesion localization, to obtain the better cosmetic result with less tissue loss and to provide negative surgical margin. Aim:the aim of the study is to compare the wire-guided localization (WGL) technique with the radioguided occult lesion localization (ROLL) technique to assess their accuracy and efficacy in non-palpable breast lesions localization. Methods:From January 2018 and June2022 a total of 670 patients underwent an excision for non-palpable lesions were enrolled randomly in ROLL group (n = 320 ) and WGL (n =350 ) at Baheya center for Early Detection and Treatment of Breast Cancer. Results: There were no differences between the two groups in terms of age, localization technique.Both the localization time and the time of operation were decreased with the ROLL. Complete lesion excision with clear margins were reported in (88.2%) of ROLL patients and in (81.8%) of WGL patients. Reoperations were done as a second operation on16( 11.8%)of ROLL patients and on 29( 18.2%) of WGL patients. Conclusion:This study shows that ROLL is as effective as WGL for non-palpable breast lesions excision. Also, ROLL improve the outcomes by decreasing the duration of surgery, localization time,achieving a higher percentage of clear margin in spite of lower specimen size and scar length.
