Purpose: To perform a medical audit of screening mammography performed at Severance hospital for employees for whom breast cancer screening was recommended and who underwent mammography at Severance hospital.
Materials and Methods: We included 757 female employees of Severance hospital for whom breast cancer screening was recommended between December 2013 and February 2015. All reports were categorized on the basis of the American College of Radiology Breast Imaging Reporting and Data System (ACR-BIRADS), and we reviewed the follow-up results of women with final assessment categories of 0, 4 and 5.
Results: Among the 757 female employees who were recommended to undergo breast cancer screening, 534 (70.5%) women underwent screening mammography at our hospital. Among them, 16 women who had definite symptoms or who underwent diagnostic mammography for short-term follow-up of microcalcifications were excluded from medical audit analysis. Among the 518 women (mean age, 45 years; range, 39-62 years) who underwent screening mammography, 54 women were recalled for abnormal interpretation results (recall rate, 10.4%) and two of three women whose final assessment category was 4 or 5 were diagnosed with breast cancer. The cancer detection rate was 3.9/1,000 (2/518), PPV1 was 3.7% (2/54) and PPV2 was 66.7% (2/3). All cancers detected on screening mammography were seen as microcalcifications and were ductal carcinoma in situ. Based on the medical records of our hospital, the sensitivity
of screening mammography was 66.7% (2/3) and specificity was 89.9% (463/515).
Conclusion: Employee screening mammography performed at our hospital was an appropriate method for the detection of early breast cancer.
