钼靶X线、超声组合BI-RADS分类法指导农村妇女乳腺普查

摘要

目的:探讨应用钼钯X线(MAM)、超声(US)组合BI-RADS分类法确定农村妇女乳腺癌普查年龄的可行性.方法:954例本地区农村妇女,年龄35～60岁,平均(47.5±5.8)岁.所有妇女均接受US和MAM检查并行BI-RADS分类,US+ MAM组合分类结果为每例受检者US与MAM分类结果中的最高级别,US+ MAM分类Ⅲ类以上结果判定为高危人群并随访.将954例农村妇女及所检出的高危妇女划分为35～40岁、41～50岁、51～60岁3个年龄段,计算高危妇女在其相应年龄段所占比率,统计学分析其差异.结果:44例农村妇女被组合BI-RADS分类法评价为高危妇女,其随访结果与BI-RADS要求相符,35～40岁、41～50岁、51～60岁3个年龄段高危妇女所占比率分别为8.21％、5.32％、1.70％,其差异有统计学意义(P＜0.05).结论:应用US+MAM组合法BI-RADS分类可准确判定农村妇女乳腺癌的普查年龄.%Objective: To identify feasibility of breast carcinoma screening age in countryside women with BI-RADS classification of mammography (MAM) and ultrasonography(US) combination. Methods: 954 local countryside women (range, 35~60 years) underwent breast screening with mammography (MAM) and ultrasonography (US). The results were classified according to the breast imaging reporting and data system (BI-RADS). Result of BI-RADS classification came from the highest score of MAM plus US classification. BI-RADS class III was regarded as high risk of breast carcinoma and follow-up. Women with high risk of breast carcinoma were divided into three groups of 35~40, 41~50, 51 ~60 according their age. High risk incidence of breast carcinoma in three groups were calculated and compared. Results: Among 954 screened countryside women, 44 women were found to be in high risk of breast carcinoma according to BI-RADS (US+MAM combination) classification by methods and follow-up result accord with BI-RADS request. High risk incidence of breast carcinoma in three groups of 35~40, 41~50, 51 ~60 years old women were 8. 21%, 5. 32%,1. 70% respectively, with statistically significant differences ( P < 0. 05). Conclusion: BI-RADS classification of mammography(MAM) and ultrasonography(US) combination could accurately i-dentify countryside women screening age of breast carcinoma.
