Abstract:
Objective: To evaluate the relationship between preoperative magnetic resonance imaging (MRI) examination and the success rate and prognosis of breast-conserving surgery in ductal carcinoma in situ (DCIS) patients. Methods: Patients with DCIS received surgery between January 2009 and January 2017 in the breast cancer medical record database of Shanghai Jiao Tong University were retrospectively analyzed. Patients who received preoperative MRI was defined as MRI group, who did not receive preoperative MRI was defined as non-MRI group. Results: A total of 210 DCIS patients were included, of which 167 cases in the MRI group and 43 cases in the non-MRI group, respectively. Initial negative resection margin rates were similar between MRI and non-MRI groups undergoing breast-conserving surgery (91.0% vs. 97.7%, P=0.142). There was also no significant difference in the success rate of breast-conserving surgery between MRI and non MRI groups (95.2% vs. 100.0%, P=0.143). In terms of prognosis, there was no significant difference in 10-year loco-regional recurrence rate (4.8% vs. 2.3%, P=0.426) and breast cancer related mortality (0.9% vs. 0.5%, P=0.668) between MRI and non-MRI groups. Conclusions: Preoperative breast MRI examination in patients with DCIS had no effect on the rate of negative resection margin, success rate of breast preservation and the prognosis of the patients.
