Assessment of the Status of Resection Margins in Patients with Breast Cancer During Breast-Conserving Surgery Using Intraoperative Mammography

The results of surgical treatment of 56 patients were analyzed. All patients were undergone on breast-conserving surgery with intraoperative X-ray control on a mammographic digital device.The mean time to complete the study was 10 minutes, which did not significantly affect the duration of the operation.Of the 56 studied preparations after breast-conserving surgery, a positive resection margin (R1) was found in 1 case during a planned histological examination, which is associated with a high X-ray density of the patient’s breast tissue. In 2 cases, positive resection margins (DCIS) were detected, additional excision made it possible to avoid repeated surgical intervention. In 1 case, a false positive result was obtained, which did not negatively affect the results of surgical treatment. There were no false negative results.
