摘要

目的探讨化生性乳腺癌(metaplastic breast carcinoma

MPBC)的临床病理及超声特点，并与同期随机的非特殊类型浸润性癌（invasive ductal breast carcinoma of no special type

IDC-NOS）进行鉴别诊断。方法回顾性分析2015年1月～2020年12月在我院经手术病理证实的33例MPBC及66例IDC-NOS的临床病理和超声特征。结果 MPBC最常见的超声表现如下：低回声肿块、边缘模糊、形态不规则、Adler II～III级、后方回声增强。MPBC的腋窝淋巴结转移率低于IDC-NOS。鳞状细胞癌是MPBC的常见病理类型，三阴型是其主要的病理分子分型。MPBC的Ki-67的平均值（59.4%）高于IDC-NOS（37.5%）。在临床表现方面，MPBC与IDC-NOS间无统计学意义（P>0.05）。结论 MPBC可表现出不同于IDC-NOS的临床病理学及超声特点。

Abstract

Objective The aim of this study was to investigate the clinicopathological and ultrasonographic characteristics of metaplastic breast carcinoma（MPBC）and differential diagnosis from invasive ductal breast carcinoma of no special type (IDC-NOS) selected at the same time randomly. Methods We retrospectively reviewed the clinicopathological and ultrasonographic characteristics of 33 patients with MPBC and 66 patients with IDC-NOS confirmed by pathology in our hospital from January 2015 to December 2020. Results The most common features of MPBC observed in ultrasound were as follows:hypoechoic mass

indistinct margin

irregular shape

Adler II～III

posterior acoustic enhancement.The rates of axillary nodal involvement were lower than that of IDC-NOS. Squamous cell carcinoma was the common pathological type of MPBC. Triple negative type was the main molecular subtype of pathology. The average score of Ki-67 （59.4%）was higher than that of IDC-NOS (37.5%).There were no significant differences in clinical manifestations (P>0.05). Conclusion Compared with IDC-NOS

MPBC can show the differential clinicopathological and ultrasonographic characteristics.
