摘要

目的：

研究乳腺单纯型浸润性微乳头状癌（pure invasive micropapillary carcinoma，PIMPC）的超声特征及其与病理学特征的相关性。

方法：

选取2010年1月2016年5月于深圳市龙华区人民医院行手术治疗且术后病理学检查证实为PIMPC的47例患者为研究对象，同期选取乳腺单纯型浸润性导管癌（invasive ductal carcinoma，IDC）患者40例为对照组，观察并比较PIMPC与IDC的超声表现，评价超声在PIMPC腋窝淋巴结转移中的应用价值。

结果：

两组之间患者年龄、病灶大小、病灶位置及病灶分布等差异无统计学意义（

＞0.05），而病灶直径、边缘毛刺、边缘蟹足状改变、内部回声、后方回声、纵横比、Alder血流分级及超声弹性成像评分差异有统计学意义（

＜0.05）。以术后病理学检查结果为金标准，超声诊断PIMPC腋窝淋巴结转移的灵敏度、特异度、阳性预测值和阴性预测值分别为52.94％、76.92％、85.71％和38.46％。

结论：

PIMPC超声表现主要为形态不规则、边界不清、边缘毛刺及低血流信号，与乳腺肿瘤组织病理学特征密切相关。此外，超声对提示PIMPC腋窝淋巴结转移具有一定价值。

Abstract

Objective:

To investigate the correlation between ultrasonic and pathological features of pure invasive micropapillary carcinoma (PIMPC).

Methods:

Forty-seven PIMPC patients confirmed by pathological examination were selected as subjects in People's Hospital of Longhua District

Shenzhen from Jan. 2010 to May 2016. And 40 cases of invasive ductal carcinoma (IDC) were selected as controls during the same period. The ultrasonic manifestations

were analyzed to evaluate the value of ultrasonic manifestations in the diagnosis of PIMPC axillary lymph node metastases.

Results:

There was no difference in age

lesion size

lesion location

lesion distribution (

＞0.05) between the two groups

but the lesion diameter

spiculated or crab-like margins

internal echo

posterior echo

aspect ratio

Alder's blood flow grading and ultrasound elastography score were significantly different (

＜0.05). The postoperative pathological results were set as gold standard

and the sensitivity

specificity

positive predictive value and negative predictive value of ultrasonography for the diagnosis of PIMPC axillary lymph node metastases were 52.94%

76.92%

85.71% and 38.46%

respectively.

Conclusion:

The main ultrasonic manifestations of PIMPC are irregular shape

unclear boundary

spiculated margin and low blood flow signal

which are closely related to the pathological characteristics of the tumor. In addition

ultrasonography is valuable in identifying axillary lymph node metastases in PIMPC patients.
