摘要
目的：探讨超声乳腺影像报告和数据系统对诊断乳腺癌的应用价值。方法：选择患乳腺疾病并将行外科手术患者71例，应用高频彩色多普勒对双侧乳房进行扫查。根据BI-RADS对乳腺病灶进行分级，选择BI-RADS 3～5级的患者61例（78个病灶），将乳腺BI-RADS分级情况和病理切片结果进行比较和分析，评估BI-RADS分级对于鉴别乳腺癌的效能。结果：在61例患者（78个病灶）中，病理学活检结果显示：24个BI-RADS 3级的病灶中，良性20个（83.33％），恶性4个（16.67%）；29个BI-RADS 4级的病灶中，良性3个（10.34％），恶性26个（89.66％）；25个BI-RADS 5级的病灶中，良性0个（0），恶性25个（100%）。BI-RADS分级诊断乳腺癌的敏感度和特异度分别为92.73％、86.96％。BI-RADS 3～5级病灶在病变边缘、边界、回声、周围组织、钙化、血管分布、血流RI值间的差异均有统计学意义（P<0.01）。结论：BI-RADS分级诊断乳腺癌的敏感性和特异性较高。在高频彩色多普勒超声检查乳腺中，应用BI-RADS分级对于诊断乳腺癌和指导治疗方案具有重要的临床意义。
Abstract
Objective: To study the role of BI-RADS classification(Breast imaging reporting and data system) in ultrasonic diagnosis of breast cancer. Methods: A total of 71 patients with breast diseases who would undergo surgery were selected for study. All the patients underwent bilateral breast examination with high-frequency color Doppler ultrasonography. According to BI-RADS classification, 61 patients(78 breast lesions) with BI-RADS grade 3~5 were recruited. The diagnostic characteristics of high-frequency color Doppler ultrasonography about breast lesions with different BI-RADS were compared with the histopathological diagnosis. Then the efficacy of BI-RADS classification for the identification of breast cancer was assessed. Results: In all the 61 patients(78 breast lesions), confirmed by histopathology, 24 were BI-RADS grade 3, in which 20(83.33%) were benign, 4(16.67%) were malignant. Twenty-nine breast lesions were BI-RADS grade 4, and histopathology confirmed 3(10.34％) were benign, 26(89.66％) were malignant． Twenty-five lesions were BI-RADS grade 5, and all the lesions were malignant confirmed with histopathology(100％)． Sensitivity and specificity were 92.73% and 86.96% respectively in the diagnosis of breast cancer by BI-RADS classification. Statistical difference was found in BI-RADS grade 3, 4, 5 in margin, lesion boundary, acoustic feature，the changes of surrounding tissue，calcification in mass, vascularity in lesion blood flow and resistance index(RI). Conclusion: The sensitivity and specificity of the BI-RADS classification were high in diagnosing breast cancer. It has important clinical significance for high-frequency color Doppler ultrasound in the diagnosis of breast cancer and treatment planning.
