乳腺导管内癌超声声像图特征和临床病理的相关性研究

目的:回顾性分析乳腺导管内癌常见超声表现,探讨导管内癌超声图像特征和临床病理的相关性.方法:回顾性分析59例乳腺导管内癌(其中21例伴微浸润)超声检查结果,总结导管内癌常见超声声像图特征.根据病灶超声声像图特征,将全部病例分为超声肿块型和超声非肿块型2大类,研究这两类图像特征与患者钼靶、病理分级及ER、PR、CerbB-2 、P53、bcl-2表达的相关性.结果:59例导管内癌(DCIS)超声声像图表现多样,31例(52.5%)为肿块型,28例为非肿块型包括:11例(18.6%)导管扩张型,5例(8.5%)微小结节型,4例(6.8%)片状低弱回声型,2例(3.4%)仅见钙化而无其他图像改变,6例(10.2%)超声未见异常.超声肿块型DCIS通常钼靶也多表现为肿块影(67.7%), 超声非肿块型DCIS钼靶上以钙化为主要表现 (64.3%),组间分布有统计学差异(P<0.01).超声肿块型组中,高级别DCIS较少,占38.7%, ER、PR阳性率较高,为83.9%和77.4%;超声非肿块型组中,高级别DCIS较多,占67.9%(P=0.02),ER、PR阳性率较低,为53.6% (P=0.01)和46.4% (P=0.01),组间分布均有统计学差异.结论:超声非肿块组DCIS高级别比例和激素受体阴性表达明显高于超声肿块组.DCIS非肿块的超声声像图特征提示肿瘤高级别和激素受体阴性可能性大,间接预示肿瘤分化差、侵袭性强.超声非肿块型可能是DCIS预后不良的指标.

An analysis of the correlation between sonography and pathology of ductal carcinoma in situ of the breast

Objective:To describe the sonographic appearances of ductal carcinoma in situ(DCIS),and to analyze the correlation between the sonographic appearances and pathologic features.Methods: Records of 59 women with diagnosis of DCIS(including 21 cases of microinvasive DCIS) were reviewed retrospectively.According to the sonographic characteristics,59 lesions were classified into two groups:lesions of sonographic mass and of sonographic nonmass.The correlation between the sonographic appearances and mammographic f...
