Ultrasound-using breast cancer detection trial in the community of Central Vietnam: initial results and proposal

BACKGROUND: Breast cancer is the most common malignancy among Vietnamese women. While breast ultrasound is widely accessible, mammography remains unavailable in many areas in Vietnam. There is a limited amount of data about breast cancer detection by ultrasound in the community of the country. This study aimed to evaluate the utility of ultrasound as a primary modality for early breast cancer detection at local health centers.METHODS: We recruited women from the age of 30 and above in the community into this descriptive cross-sectional study. In collaboration with the local Vietnam Women’s Union and health centers, participants completed questionnaires and underwent free breast ultrasound examinations conducted by experienced radiologists. Breast lesions were categorized using the ACR BI-RADS. Women with suspicious findings were recalled to Hue University of Medicine and Pharmacy Hospital for further diagnostic evaluation.RESULTS: Among 6073 participating women, the mean age was 47.3±9.9 years (range: 30-84). Suspicious lesions (Breast Imaging-Reporting and Data System 4-5) were detected in 102 women (1.7%), with five cases confirmed as malignant, resulting in a cancer detection rate (CDR) of 0.82 per 1000 women. Additionally, 58% of participants reported sedentary behavior as a modifiable risk factor.CONCLUSIONS: This study underscores the feasibility of using ultrasound for early breast cancer detection in community settings. The recall rate, CDR and high prevalence of sedentary behavior suggest the need for a community-based approach to improve breast CDR in Central Vietnam.
