An audit of clinically triaged women at low risk for breast cancer presenting to the Helen Joseph Mammography Unit

Keywords: clinically triaged women, breast cancer, low risk

Abstract

Background: The Helen Joseph Hospital (HJH) breast clinic utilises a clinical triage system to stratify patients based on their risk of breast cancer into high-, medium-, or low-risk profiles. This allows for timeous imaging and subsequent management of those patients at increased risk for breast cancer. The primary objective was to determine the cancer detection rate (CDR). The secondary objective was to correlate biopsy results with the Breast Imaging-Reporting and Data System (BI-RADS) risk assessment.

Methods: A retrospective audit of the patients at low risk for breast cancer who were referred to the breast imaging unit (BIU) in 2019 at HJH. Patients were clinically assessed as low risk based on a triage form and were identified using the imaging files stored in the BIU. Results were recorded on Microsoft Excel and calculated as per the American College of Radiology guidelines.

Results: The total population sample consisted of 398 patients. Two patients were characterised as BI-RADS 4 and underwent breast biopsies. One patient was diagnosed with histologically proven breast cancer. The CDR was 2.51%. The most representative groups were the age group of 60–69 years, BI-RADS breast density B and BI-RADS risk assessment 2.

Conclusion: Amongst the low-risk population, both the CDR and spectrum of disease was comparable to that of a screening population. This may be due to the use of a triage system prior to imaging, as well as an increase in clinical awareness of breast cancer within a tertiary institution.
