Aim: The roles of MX and US in the preoperative evaluation of breast cancer are quite defined; instead, the role of MRI in this setting is still under examination. We have conducted a retrospective observational study with the purpose of understand if there is, in our experience, an increased number of ipsilateral and contralateral mastectomy in patients underwent to MRI.
Materials and method: We collect all the patients underwent to surgery for early-breast cancer in 2023 and we divided the included patients in two groups: MRI group with the patients who underwent 3T MRI before treatment and CONTROL group with patients who received surgical management without preoperative MRI.
Results: In the MRI group there are 46 BCS and 29 mastectomies, of which 5 bilateral mastectomies and 1 bilateral BCS; in MRI group there were no reinterventions. In CONTROL group are included 294 patients; of them, we had 213 BCS and 100 mastectomies with 19 bilateral surgeries with 7 patients underwent to bilateral mastectomies, 9 to bilateral BCS and 3 to BCS in one breast and to mastectomy to the other; in CONTROL group there were 2 reinterventions. Our statistical analysis haven’t revealed a statistically significant difference of the number of mastectomies between two group; at a multivariate analysis we have found out that people with mutation like BCRA have more frequently mastectomy (p = 0,056), and people older have more frequent BCS (p<0.001).
Conclusion: According to some article in literature pre-operative MRI doesn’t have an impact on the number of mastectomies if compared to a non -MRI group. We suppose that if multicentric regional study will be performed this result could change because of the selection of patients and the surgical preference of our centre.
