Purpose Contrast-enhanced breast magnetic resonance imaging (MRI) is becoming more prevalent among patients newly diagnosed with breast cancer, aimed at assessing the extent of the disease prior to surgical intervention (1-3). When breast MRI reveals a greater extent of disease compared to other imaging methods, and breast-conserving surgery (BCS) remains feasible, the objective is to ensure the complete surgical excision of the pathological area with clear margins. In some circumstances, employing MRI guidance to delineate either all or part of the affected area...
Read more Methods and materials The local Institutional Review Board's research ethics committee approved this retrospective study, and the need for informed consent was waived.We retrospectively reviewed all MRI-guided procedures per­formed between January 2015 and December 2021 in our institution. The inclusion criteria were as follows: Patients with newly diagnosed breast cancer, either invasive cancer or ductal carcinoma in situ (DCIS), undergoing MRI-B prior to surgery. Previous breast imaging was available for review, including ultrasound, mammogram and breast MRI to assess disease extent. Pathological results of prior breast...
Read more Results Fifty-seven women who met the inclusion criteria were enrolled in the study.The mean age of the participants was 55 years (range 35-79). Twenty-six percent of the women had a family history of breast cancer, and 17% had a personal history of the disease. Eighteen percent of women had involved lymph nodes. The most frequent pathological diagnosis was a combination of infiltrative ductal carcinoma (IDC) and DCIS (24/57, 42%), followed by isolated DCIS (26%) and isolated infiltrative lobular carcinoma ILC) or...
Read more Conclusion MRI-guided bracketing before BCT is associated with an acceptable rate of positive margins and local recurrence. However, optimizing patient selection is essential to minimize unnecessary bracketing and improve surgical outcomes.
