不同病理亚型乳腺粘液癌的超声表现特征

目的探讨不同病理亚型乳腺粘液癌(MBC)的超声表现特征。方法选取39个MBC病灶,比较传统单纯性乳腺粘液癌(cPMBC)、乳腺粘液微乳头状癌(MUMPC)及混合型乳腺粘液癌(MMBC)的临床及超声表现特点,采用SPSS 23.0统计学软件对数据分析。结果MBC多表现为平行方位的低回声团块,少见液化及微钙化;cPMBC、MUMPC多呈椭圆形或分叶状,后方回声增强及伴侧方声影,前者多富血供,后者多乏血供;MMBC边缘多呈角状或蟹足状且乏血供,后方回声多无改变,少见侧方声影。三组癌的年龄、最大径、位置、纵横比、内部回声、微钙化、导管变化、血流Adler分级及阻力指数比较差异无统计学意义(P>0.5),cPMBC与MMBC的边缘、后方回声模式、侧方声影比较差异有统计学意义(P<0.0167),MMBC较cPMBC与MUMPC更易出现淋巴结转移(P<0.0167)。结论MBC的超声表现与其组织病理学特点相关,cPMBC、MUMPC与MMBC的声像特征各具特点。

Ultrasonographic features of mucinous breast carcinoma in different pathological subtypes

Objective To ivestigate the ultrasonographic features of mucinous breast carcinoma(MBC).Methods 39 lesions of MBC confirmed by pathological examination were selected.We compared the differences in clinical and ultrasound features between with conventional pure mucinous breast carcinoma without micropapillary pattern(cPMBC),mutinous mitropapillary cartinoma(MUMPC),and mixed mucinous breast carcinoma(MMBC).SPSS 23.0 software was used for data analysis.Results Most of MBCs showed isoechoic with parallel orientation,and rare of cystic component or calcification.Most of cPMBCs and MUMPCs showed ellipse or differential leaf shape,distal acoustic enhancement and lateral shadow,while most of MMBCs showed angular protrusion or glitch edge,no change in the rear echo and rare of lateral shadow.There was no significant difference between the three groups based on age,maximum diameter,location,palpation,internal echogenicity,calcification,catheter change,blood Adler grade and resistance index(P>0.05).There was significant difference between cPMBC and MMBC based on edge,distal acoustic and lateral shadow(P<0.0167).MMBC was more prone to lymph node metastasis than cPMBC and MUMPC(P<0.0167).Conclusion The main ultrasonic features of MBC are related to the pathological characteristics of the tumor,cPMBC,MUMPC and MMBC have their own ultrasound performance characteristics.
