超声BI-RADS 3类和4A类病变分类的影响因素

Influence Factors of Ultrasound Breast Lesion Classification with BI-RADS Category 3 and 4A

目的:探讨患者年龄及病灶大小对乳腺超声BI-RADS(乳腺影像报告和数据系统)3类和4A类病变分类的影响。方法:依据BI-RADS分类标准,对405例乳腺BI-RADS 3类(240例)及4A类(165例)患者年龄及病灶大小进行分析。结果:240例BI-RADS 3类中良性病灶240例(100%),恶性病灶0例;165例BI-RADS 4A类中良性病灶158例(95.76%),恶性病灶7例(4.24%)。在BI-RADS 3类和4A类病变分类中,患者年龄差异具有统计学意义(P<0.05),病灶大小差异无统计学意义(P>0.05);BI-RADS 4A类良、恶性病灶中,患者年龄差异具有统计学意义(P<0.05)。结论:患者年龄对BI-RADS3类和4A类乳腺病变分类具有重要的意义,而病灶大小对分类意义不大。

Objective： To investigate the effects of age and the lesions size on diagnosis of category 3 and 4A in breast imaging report and data system（BI-RADS）. Methods： Age, lesions size and ultrasound lesion classification according to the BI-RADS of 405 cases（240 cases diagnosed BI-RADS category 3 and 165 cases diagnosed BI-RADS category 4A）of reports were conducted a retrospective analysis. Results： Among 240 cases BI-RADS category 3 lesions, 240 cases（100%）were benign, and no case（0%）was malignant.While among 165 cases BI-RADS category 4A lesions, there were 158 cases of benign（95.76%）, and 7 cases of malignant（4.24%）.Data showed a statistical significance between age difference and diagnosis classification（P〈0.05）, but no statistical significance between lesion size and diagnosis classification（P〈0.05）. The age of patients were found to have significant influence on pathological diagnosis in category 4A lesions（P〈0.05）. Conclusion： Age, but not lesion size, significantly influenced breast lesions diagnosis with BI-RADS category 3 and 4 A.
