Intraductal component is a risk factor for local recurrences of ductal carcinomas after breast-conserving therapy. Up to the present, only microcalcifications have been recognised as a mammographic sign of the intraductal component. The authors examined 67 ductal carcinomas; in addition to microcalcifications they paid attention to spicula at the margin of the tumors. These have been examined histologically and it has been shown that in 91% of the cases the spicula contain more or less marked intraductal carcinomatous tissue. Even in 23 cases (34.3%) the spicula consisted entirely of intraductal components. Microcalcifications in this respect are of less diagnostic importance. In 29 cases there were additional invasive foci which were not evident macroscopically and in four cases intramammary lymph node metastases were discovered radiologically only. The slice-specimen radiography carried out by the authors provides additional help in evaluating of accurate pathologic margins of "lumpectomy".
导管内成分是保乳治疗后导管癌局部复发的一个危险因素。到目前为止，只有微钙化被认为是导管内成分的乳腺X线征象。作者检查了67例导管癌；除微钙化外，他们还关注肿瘤边缘的毛刺征。对这些进行了组织学检查，结果显示在91%的病例中，毛刺征或多或少含有明显的导管内癌组织。甚至在23例（34.3%）病例中，毛刺征完全由导管内成分组成。在这方面，微钙化的诊断重要性较小。在29例病例中有额外的肉眼不可见的浸润灶，在4例病例中仅通过影像学发现了乳腺内淋巴结转移。作者进行的切片标本X线摄影在评估“肿块切除术”的准确病理切缘方面提供了额外的帮助。
