Magnetic Resonance Imaging after Breast Oncoplastic Surgery: An Update.
BREAST CARE(2017)
摘要
Breast-oncoplastic surgery, allowing local tumor control and a better cosmetic outcome, is oncologically safe when applied to early-stage breast cancer. Breast cancer recurrence following conservative therapy may occur during the first 5 years after treatment, with a peak incidence after 2 years. Therefore, during the follow-up period, patients undergo a series of ultrasound (US) and mammographic examinations. However, after surgery and radiation therapy, several modifications occur in the treated breast, causing difficulties in image interpretation, especially when local recurrence is suspected. Although not included in routine follow-up, magnetic resonance imaging (MRI) is often used in clinical practice, being considered more sensitive than the conventional imaging examinations in discriminating between post-surgical tissue modifications and tumor recurrence. In this review article, we analyze expected and pathologic breast MRI findings after conservative oncoplastic surgery compared to US and mammographic findings in order to distinguish local recurrence and avoid potential pitfalls in image interpretation.
