【摘要】：目的回顾性分析107例全数字化乳腺X线摄影表现为边界清晰的乳腺肿块患者资料,探讨与肿块良恶性相关的影响因素,以提高诊断准确率。方法搜集术前诊断为BI-RADS 3类和BI-RADS 4A类单发的边界清晰乳腺肿块患者,所有肿块均有手术病理。回顾性分析患者一般资料和乳腺X线摄影表现,包括患者年龄、肿块发生部位、大小、密度、浅分叶、周围晕征、钙化等。运用单因素和多因素分析年龄、肿块最大直径、部位、肿块密度、浅分叶、周围晕征、钙化等因素对肿块良恶性的影响。结果乳腺X线摄影对于边界清晰乳腺肿块在鉴别良恶性方面,存在着征象交叉重叠。分析表明年龄与肿瘤良恶性有关,年龄每增加1岁,恶性危险性随之增加;肿块浅分叶和无周围晕征是肿瘤为恶性的危险因素,有浅分叶的肿块呈恶性可能性是无浅分叶肿块的6.68倍;无周围晕征的肿块呈现恶性的可能性是周围有晕征肿块的5.45倍。有无钙化在良恶性上无统计学差异,但其钙化在表现形态上有差异,恶性钙化细小,良性钙化粗大。结论 X线摄影表现为边界清晰的乳腺肿块,其良恶性与年龄、肿块浅分叶、肿块周围晕征密切相关,综合分析可提高诊断准确率。
[Abstract]:Objective to analyze retrospectively the data of 107 cases of breast masses with clear boundary on digital mammography, and to explore the influencing factors related to benign and malignant masses in order to improve the diagnostic accuracy. Methods the patients with BI-RADS 3 and BI-RADS 4A single margin breast masses were collected and all the masses were surgically histopathologically. The general data and mammographic findings of the patients were analyzed retrospectively, including age, location of mass, size, density, superficial lobulation, peripheral halo sign, calcification and so on. Univariate and multivariate analysis was used to analyze the influence of age, maximum diameter, location, density, superficial lobulation, peri-halo sign and calcification on the benign and malignant tumor. Results mammography had overlapping signs in differentiating benign and malignant breast masses. The analysis shows that age is related to benign and malignant tumor, and the risk of malignancy increases with the increase of age by 1 year, and the superficial lobulation and no peripheral halo sign are the risk factors of malignant tumor. The tumors with superficial lobes were 6.68 times more likely to be malignant than those without superficial lobular masses, and the masses without peripheral halo sign were 5.45 times more likely to be malignant than those with peripheral halo signs. There was no statistical difference between benign and malignant calcification, but the appearance of calcification was different, malignant calcification was small and benign calcification was coarse. Conclusion the X-ray findings of breast masses with clear boundary are closely related to age, superficial lobulation and halo sign around the masses. Comprehensive analysis can improve the accuracy of diagnosis.
