Abstract:
Objective To analyze results of breast cancer screenings in the Cancer Screening Program in Urban China (CanSPUC) during 2012-2013. Methods In 14 cities of 9 provinces (Eastern Region: Beijing, Hebei, Liaoning, Shandong and Guangdong; Central Region: Heilongjiang and Hunan;Western Region: Chongqing and Gansu), 198 097 women aged 40-69 years who had lived in their cities for ≥3 years were surveyed through a cancer risk assessment questionnaire during 2012-2013. The questionnaires identified women considered to be at high risk for breast cancer, of whom 17 104 received screening examinations, for whom complete records of breast cancer screening and other data were available for 12 440 subjects altogether, including breast ultrasound exams for subjects 40-44 years old. Subjects older than 45 years or in whom breast imaging reporting and data system (BI-RADS) ultrasound had found≥3 lesions also underwent mammography. In this cohort, BI-RADS 3 class was defined as suspicious and BI-RADS ≥4 class as positive. Chi-square tests were used to compare breast cancer screening results by groups. Results As of October 2013, breast cancer screening percentages for the 12 440 subjects for whom full data were available were, by region, Eastern: 55.43% (6 895); Central: 21.45% (2 669); and Western:23.12% (2 876); by age, 40-44 years: 5.50% (684); ≥45 years: 94.50% (11 756). Using BI-RADS, 2018 subjects were found to have 3 lesions (detection rate:16.22%), which were distributed regionally as Eastern:19.00% (1 310 women), Central: 13.75% (367) and Western; 11.86% (341); χ2=91.45, P<0.001; and 289 were found to have≥4 lesions (detection rate:2.32%), which were distributed regionally as Eastern:2.41%(166), Central:1.54%(41) and Western;2.85%(82);χ2=11.04, P=0.004. Women aged 50-54 years had the highest detection rate of BI-RADS 3 lesions at 18.74% (561/2 994), and those aged 40-44 years had the highest detection rate of BI-RADS ≥4 at 2.92% (20/684). Conclusion Detection rates of BI-RADS ≥4 lesions were highest in the Western region and in women aged 40-44 years, and lowest in the Central region and in women aged 60-64 years. Detection rates of BI-RADS 3 lesions were highest in the Eastern region and in women aged 50-54 years and the lowest in the Western region and in women aged 60-64 years.
