典型乳腺癌与不典型乳腺癌的超声图像对比分析

[摘要] 目的 探讨典型乳腺癌与不典型乳腺癌在超声图像上的区别,提高超声对不典型乳腺癌的认识,减少误诊及漏诊率。方法 回顾性分析经手术或穿刺病理证实为乳腺恶性肿瘤患者 58 例,分别检查二维图像包括边界、回声、形态等,对比分析典型乳腺癌与不典型乳腺癌之间的差异。结果 典型乳腺癌 32 例,不典型乳腺癌 26例。超声不典型乳腺癌包括腺体紊乱型 13 例( 50.0% ),微钙化型 5 例( 19.2% ),小结节或囊肿型 5 例( 19.2% ),囊实性型 2 例( 7.7% ),隐匿型 1 例( 3.8% )。超声声像图典型的乳腺癌,乳腺超声与乳腺钼靶 X 线、 MRI 相比,三者之间差异具有统计学意义(χ2 =7.199 ,P <0.05 )。超声声像图不典型的乳腺癌,乳腺超声与乳腺钼靶 X 线和 MRI对比,三者差异无统计学意义(χ2 =2.791 ,P >0.05 )。结论 不典型乳腺癌超声声像逐渐被认识,不同类型的影像学诊断方法各有利弊,需要综合检查、综合判断,才能达到早期发现、早期诊治的目的。

Contrast analysis of ultrasound images of typical breast cancer and atypical breast cancer

［Abstract］ ObjectiveTo investigate the ultrasound characteristics between the typical and atypical breast cancer and improve the understanding for the atypical breast cancer， and to reduce the misdiagnosis rate and missed diagnosis rate. MethodsRetrospective analysis of 58 cases of breast cancer patients confirmed by surgery or puncture pathology were performed. The differences are analyzed from two dimensional image including boundary, echo, shape and so on. ResultsThirty two typical and twenty six atypical breast cancers were enrolled in the study. Aatypical breast cancers included 13 cases of glandular structure disorder(500%), 5 cases of microcalcification type(192%), 5 cases of small nodules or cysts type(192%), 2 cases of cystic and solid type(77%), 1 case of occult type(38%). For the typical breast cancer, there was statistically significant difference between the ultrasound compared with X ray mammography and MRI（χ2=7.199，P<005）, but no statistically significant difference in the atypical breast cancer （χ2=2791，P＞005）. ConclusionMore and more atypical breast cancers were discovered. Different imaging examination have its virtues and faults. We should combined all the imaging examinations to achieve early detection, early diagnosis .
