We retrospectively analysed mammographies of 909 ductal carcinoma in situ (DCIS) (1980-1999) and compared our results to those of literature. Microcalcifications were present in 75% of the cases, and soft-tissue abnormalities in 27% cases with association with calcifications in 14% of cases. Palpable masses were found in 12% of the cases and nipple discharge was present in 12% of the cases. The radiographic-pathologic correlation allowed to suspect the DCIS "aggressiveness" on radiologic signs. Granular, linear, branching and/or galactophoric topography of the microcalcifications were correlated with necrosis, grade 3, comedocarcinoma type. A number of microcalcifications higher than 20 was correlated with necrosis and grade 3. Mammographic size was correlated to histologic size. Masses were correlated with grade 1. A diagnosis strategy can be proposed with a multidisciplinar approach.
我们回顾性分析了909例导管原位癌（DCIS）（1980 - 1999年）的乳房X线照片，并将我们的结果与文献结果进行比较。75%的病例存在微钙化，27%的病例有软组织异常，其中14%的病例与钙化有关。12%的病例可触及肿块，12%的病例有乳头溢液。影像学与病理学的相关性使得能够根据放射学征象怀疑DCIS的“侵袭性”。微钙化的颗粒状、线性、分支状和/或输乳管样形态与坏死、3级、粉刺癌类型相关。微钙化数量超过20个与坏死和3级相关。乳房X线照片上的大小与组织学大小相关。肿块与1级相关。可以采用多学科方法提出一种诊断策略。
