摘要:

目的 探讨剪切波弹性成像(SWE)在乳腺非肿块病变(NML)良恶性鉴别诊断中的作用,并阐明其临床意义。 方法 选取158例乳腺NML患者,根据患者术后病理类型分为良性病变组( n=83)和恶性病变组( n=75),患者术前行常规超声及SWE检查,记录病变的SWE参数,包括病变内部及病变周围组织1、2和3 mm的最大值(Emax)、平均值(Emean)、最小值(Emin)、标准差(Esd)及是否存在硬环征。分析2组NML患者SWE特征和各SWE参数差异,并绘制受试者工作特征(ROC)曲线,计算曲线下面积(AUC)、特异度和灵敏度。 结果 2组NML患者年龄构成、病变大小、是否触及和是否绝经方面比较差异有统计学意义( P<0.01)。2组患者中所有病变均表现为低回声和不规则形状。与良性病变组比较,恶性病变组患者出现非平行、钙化和后方回声衰减患者百分率明显升高( P<0.01),出现无血供表现百分率明显降低( P<0.01)。与良性病变组比较,恶性病变组NML患者病变内部Emax、Emean和Esd均明显升高( P<0.01),病变周围组织1、2和3 mm处Emax、Emean和Esd均明显升高( P<0.01)。恶性病变组患者病变周围组织出现环形或半环形的红色区域为硬环征表现。与良性病变组比较,恶性病变组NML患者中硬环征百分率明显升高( P<0.01)。在良性和恶性病变组NML患者中,与病变内部比较,病变周围组织1、2和3 mm处Emin均明显降低( P<0.01)。病变内部及病变周围组织1、2和3 mm Emax的AUC分别为0.872、0.860、0.873和0.866,Emean的AUC分别为0.796、0.822、0.820和0.815,Esd的AUC分别为0.832、0.857、0.859和0.842。病变内部Emax的灵敏度和特异度分别为85.33%及83.13%。病变周围组织1 mm处 Emax的灵敏度和特异度分别为82.67%及80.72%;病变周围组织2 mm处Emax的灵敏度和特异度分别为78.67%及87.95%;病变周围组织3 mm处Emax的灵敏度和特异度分别为 80.00%及86.75%;病变周围组织2 mm处Esd 灵敏度最高(93.33%)。 结论 病变内部及病变周围组织的SWE参数和硬环征表现能够为乳腺NML良恶性的鉴别诊断提供参考依据,具有良好的诊断性能。

Abstract:

Objective To discuss the effect of shear wave elastography (SWE) on the differential diagnosis of benign and malignant breast non-mass lesion (NML), and to clarify its clinical significance. Methods A total of 158 patients with breast NML were selected and divided into benign lesion group ( n=83) and malignant lesion group( n=75) according to the postoperative pathological type of the patients.The routine ultrasound and SWE examinations were conducted before operation, and the SWE parameters of the lesions, including the maximum (Emax), average (Emean),minimum (Emin), standard deviation (Esd) and whether the stiff rim sign presented or not at 1, 2 and 3 mm around the lesion were recorded. The SWE characteristics and differences in SWE parameters of the NML patients between two groups were analyzed, and the receiver operating characteristic curve(ROC) was plotted, and the area under curve (AUC), specificity and sensitivity were calculated. Results There were statistically significant differences in age, lesion size, palpation, and whether menopause had crested of the NML patients between two groups( P<0.01). All the lesions of the patients in two groups appeared as hyperechoic and irregular in shape. Compared with benign lesion group, the percentage of the patients with non-parallel, calcification and posterior echo attenuation in malignant lesion group was significantly increased ( P<0.01), and the percentage of the patients without blood supply was significantly decreased ( P<0.01). Compared with benign lesion group, the Emax, Emean, and Esd of the NML patients in malignant lesion group were significantly increased ( P<0.01), and the Emax, Emean, and Esd at 1, 2, and 3 mm around the lesion were all increased ( P<0.01). The stiff rim sign manifested as a circular or semi-circular red region around the lesions of the patients in malignant lesion group. Compared with benign lesion group, the percentage of hard rim sign of the NML patients in malignant lesion group was significantly increased ( P<0.01).Compared with inside the lesion,the Emin at 1,2 and 3 mm around the lesion of the NML patients in benign lesion group and malignant lesion group were decreased( P<0.01). The AUC of Emax at 1, 2 and 3 mm around the lesion were 0.872, 0.860, 0.873 and 0.866,respectively; the AUC of Emean were 0.796, 0.822, 0.820 and 0.815,respectively; the AUC of Esd were 0.832, 0.857, 0.859, and 0.842,respectively;the sensitivity and specificity of Emax inside the lesion were 85.33% and 83.13%,respectively;the sensitivity and specificity of Emax at 1 mm around the lesion were 82.67% and 80.72%,respectively; the sensitivity and specificity at 2 mm around the lesion were 78.67% and 87.95%,respectively; the sensitivity and specificity at 3 mm around the lesion were 80.00% and 86.75%,respectively; the specificity of Esd at 2 mm around the lesion was highest (93.33%). Conclusion The SWE parameters inside and around the lesion and the manifestation of stiff rim sign can provide the reference for the differential diagnosis of benign and malignant breast NML, and have good diagnostic performance.
