乳腺癌不同阶段钙化X线征像分析

Mammographic signs of calcification in different stages of breast carcinoma

目的研究钙化在乳腺癌不同阶段X线征像。方法收集行全数字化乳腺X线摄影出现钙化并经手术病理证实的乳腺癌277例,回顾性分析钙化X线征像,并与病理进行对照研究。结果乳腺癌钙化形态、分布、数目及伴随情况在导管原位癌、导管原位癌伴微浸润、浸润性导管癌差异有统计学意义(P<0.05)。结论根据钙化X线征像初步鉴别不同阶段乳腺癌,为临床提供诊疗依据。

Objective To study the mammographic signs of calcification in different stages of breast carcinoma. Methods Totally 277 cases of breast carcinoma were collected. These patients had mammographic signs of calcification on the full-field digital mammography （FFDM） photographs and were confirmed by surgical pathology. The mammographic signs of calcification were retrospectively analyzed and compared with the pathological findings of the lesions. Results There were statistical differences in the morphology, distribution, number and simultaneous phenomenon of calcification foci among ductal carcinoma in situ, ductal carcinoma in situ with microinvasion and invasive ductal carcinoma （P 〈 0.05）. Conclusions Different stages of breast carcinoma could be preliminarily identified according to the mammographic signs of calcification, which provide the basis for clinical diagnosis and treatment.
