Abstract
We assessed prospectively the impact of preoperative breast magnetic resona nce (MRI) on the extent of surgical resection. Of 131 breast cancers treate d with breast conservation over 18 months, 41 underwent preoperative MRT. S cans were shown to the operating surgeon to indicate the location of lesion s and their local extent. Clinical information and histological assessment of wide local excision specimens were compared between those patients who u nderwent preoperative MRI and those who did not. There was no significant difference between the MRI group (N=41) and no-MRI group (n=90) in average specimen weight (P = 0.72) or circumferential marg in status (P = 0.17). Logistic regression analysis demonstrated a positive correlation between margin status and patient age (P = 0.045), younger pati ents being more likely to have involved margins, and a negative correlation with MRI status (P = 0.006) these women having an MRI being more likely to have negative margins. Preoperative MRI does not currently influence the extent of surgical resect ion in breast conservation surgery.
