钼靶摄影中微钙化在乳腺癌诊断中的价值

The value of microcalcification in mammography findings in diagnosis breast cancer

目的 探讨乳腺钼靶摄影中微钙化对乳腺癌的诊断价值。方法 回顾性分析2010年4月-2016年3月有微钙化的38例经手术或穿刺活检证实的乳腺癌患者,着重对钙化颗粒的特性、钙化与肿块和病理分型的关系进行分析。结果 乳腺癌钙化的主要形态依次为：泥沙样、针尖样、小杆样、小叉状、团簇样钙化等,以等、低密度为主的钙化,周围伴晕征多见。微小钙化数目〉5枚/cm2者31例。浸润性导管癌患者最多、钙化率最高,以泥沙样或针尖样为主,4例原位癌为单纯钙化。单纯钙化15例,14例结节内和9例结节外见钙化。结论 钼靶摄影中微钙化颗粒X线表现对乳腺癌、特别是浸润性导管癌、原位癌的诊断有极其重要意义。

Objective To investgate the diagnostic significance of microcalcifications in breast cancer.Methods 38 female individuals of breast cancer with microcalcifications confirmed by pathology and biopsy from April 2010 to March 2016 were included in this study retrospectively.The characteristics of microcalifications,relation with mass and histopathology in breast cancer were analyzed and compared.Rusults In mammography,most microcalcifications were usually sand-shaped,pinpoind-shaped,pole-shaped,fork-shaped,clusteringly-shapde.The middle and low dense microcacifications with halo sign were seen in most breast cancer.31 cases had 5 minutes calcifications per square centimeter.IDC with microcalfications were often seen in breast cancer.These microcalcitions most were sand-shaped or pinpoint-shaped.4 cases were caicinomas in stitu with pure microcalcifications.Pure calcifications 15 cases,calcification in mass 14 cases,calcification near mass 9 cases.Conclusion In mammography,X-ray indication of microcalcification is important finding in diagnosis of breast cancer especially caicinomas in situ and IDC on mcrography.
