目的:探讨乳腺癌全数字化乳腺X射线摄影(FFDM)征象与病理类型及分级的关系。方法:收集经病理确诊的乳腺癌患者242例,均常规行FFDM检查,对照分析FFDM征象与病理类型及分级的关系。结果:FFDM显示肿块174例,钙化117例,结构扭曲23例,局灶性致密影12例,导管征22例;浸润性导管癌多表现为单纯肿块或肿块伴钙化,导管内癌多表现为单纯钙化,单纯肿块、肿块伴钙化和单纯钙化在各病理类型乳腺癌之间的差异有统计学意义,P<0.05;除黏液癌和髓样癌肿块边缘多较清楚,其他类型癌多呈星芒状和浸润状边缘,肿块边缘和钙化分布的特征在各病理类型间的差异有统计学意义,P<0.05。乳腺癌病理分级与有无肿块、有无钙化、有无局灶致密影无关(P>0.05),与肿块外形是否规则、肿块边缘是否有星芒征、有无结构扭曲有关(P<0.01),Ⅲ级肿瘤的结构扭曲率、肿块不规则者及星芒征高于Ⅰ和Ⅱ级。结论:乳腺癌的肿块、钙化等X射线特征与病理类型和分级有关。
Objective: To investigate the relationship between breast cancer full digital mammography (FFDM) signs and pathological types and grading. Methods: A total of 242 patients with pathologically diagnosed breast cancer were collected. FFDM was performed routinely and the relationship between FFDM signs and pathological types and grading was analyzed. Results: FFDM showed 174 cases of lumps, 117 cases of calcification, 23 cases of structural distortion, 12 cases of focal dense shadow and 22 cases of ductal signs. Infiltrating ductal carcinoma mostly showed simple mass or lumps with calcification. Simple calcification, simple lumps, lump calcification and simple calcification in all pathological types of breast cancer difference was statistically significant, P <0.05; except mucinous and medullary carcinoma more clear edges, most of the other types of cancer There were significant differences in the characteristics of mantle-like and infiltrative margins, tumor margins and calcification distribution between the various pathological types (P <0.05). The pathological grading of breast cancer was related to the presence or absence of tumor, calcification, presence or absence of focal dense shadow (P> 0.05), and the rules of tumor mass, The structural distortions, irregular masses and astral signs of grade Ⅲ tumors were higher than those of grade Ⅰ and Ⅱ. Conclusion: The characteristics of X-ray, such as mass and calcification of breast cancer, are related to pathological type and grade.
