伴钙化乳腺癌X线征象的研究

Analysis of mammographic characteristics of breast cancers with calcification

目的研究乳腺癌X线征象,提高对乳腺病变尤其是乳腺癌的诊断水平。方法搜集术前行钼靶X线检查术后经病理证实的伴钙化的乳腺癌患者82例及伴钙化的乳腺良性病变患者12例进行回顾性分析,将伴钙化的不同病理类型乳腺癌的X线征象进行对照;以伴钙化的乳腺癌为研究对象,设对照组,对其钙化的大小、形态、密度是否一致进行分析。结果不同病理类型乳腺癌其钼靶X线表现不一,含有钙化的病变多见于导管原位癌和浸润性导管癌,钙化伴肿块在各种病理类型乳腺癌中均可见,以浸润性导管癌为多,钙化伴结构紊乱者多见于浸润性导管癌;乳腺癌的钙化多为细钙化,且形态、密度不一致。掌握这一特征,可发现隐匿性及早期乳腺癌。结论钼靶乳腺摄影是诊断和鉴别诊断乳腺癌的重要方法。

Objective To study mammographic characteristics of breast cancers and improve their diagnostic standard. Methods Mammograms of 82 patients with breast cancers and 12 patients with benign breast diseases which were both with breast minute calcification and verified by pathology were collected. The mammograms of breast cancers were compared with that of the benign diseases, the size, shape and density of calcification identical of all kinds of pathological breast cancers with calcification were studied. Results The mammographic manifestations were different in different breast cancers, the pathology with calcification usually was in intraductal carcinoma in situ and invasive ductal carcinoma, the pathology with calcification and mass might usually be found in invasive ductal carcinoma, the pathology with calcification and structure disorder usually lied in invasive ductal carcinoma. The calcification of breast cancers was fine, and its shape and density was not identical. Conclusion in diagnosis and difference diagnosis in breast cancers.
