AimThe use ofbreast MRI for pre-operative treatment planning remains controversial. MRI can lead to further intervention, with subsequent changes to the surgical planning. This study evaluated the impact of breast MRI on surgical planning and treatment of breast cancers in our breast unit. Methods A retrospective audit was conducted on all patients treated between January 2015 and December 2017. Cancer registry, case-notes, radiological and histopathological reports were used for data collection. Results: There were 1193 cases of new breast cancers diagnosed in this 36-month study period. Of these, 185 (15.5%) patients required pre-operative MRI. Indications for performing MRI were: dense breast tissue (55/185; 29.7%), mammographically occult (55/185; 29.7%), lobular carcinoma contemplating breast conserving surgery (45/185; 24.3%), and multi-centric cancers (20/185; 10.8%), to assess contralateral breast (6/185; 3.2%), occult primary (4/185; 2.2%).One third (63/185; 34.0%) of the patients who had MRI were recalled for further investigations. Additional malignancies were found in 25 out of these 63 recalls (39.7%). Twenty five out of the 185 patients (13.5%) who underwent breast MRI had additional biopsy proven malignancies.Sixty four out of the 185 patients (34.6%) who had pre-operative MRI had their initial treatment plan modified due to MRI findings.Median time from initial presentation to treatment was 44.5 days.ConclusionWithout MRI, further malignancies would have been missed in this selected group of patients. Clear indications and local guidelines to determine the need of pre-operative breast MRI should be established.
