[目的]探讨甲状腺结节合并钙化与甲状腺癌的关系。[方法]回顾性分析2007年1月至2012年11月197例甲状腺患者的彩色超声资料与病理诊断结果。[结果]197例甲状腺结节中,钙化率为41.6%(82/197),其中甲状腺良性疾病中钙化率为21.4%(27/126),而在甲状腺癌中钙化率达77.5%(55/71)(χ2=58.684,P<0.001)。钙化诊断甲状腺癌的ROC曲线下面积为0.780(95%CI:0.710~0.850),其中微钙化ROC曲线下面积为0.748(95%CI:0.672~0.823),粗钙化ROC曲线下面积为0.625(95%CI:0.540~0.710)。[结论]钙化尤其是微钙化对于甲状腺癌的诊断价值较高。
[Objective] To investigate the relationship between thyroid nodules with calcification and thyroid cancer. [Methods] The color ultrasound data and pathological diagnosis results of 197 cases of thyroid patients from January 2007 to November 2012 were retrospectively analyzed. [Results] Among 197 thyroid nodules, the rate of calcification was 41.6% (82/197), of which calcification rate was 21.4% (27/126) in benign thyroid diseases and 77.5% (55 / 71) (χ2 = 58.684, P <0.001). The area under the ROC curve of calcified thyroid cancer was 0.780 (95% CI: 0.710-0.850). The area under the ROC curve was 0.748 (95% CI: 0.672-0.823) and the area under ROC curve was 0.625 (95% % CI: 0.540 ~ 0.710). [Conclusion] Calcification, especially microcalcification, has a higher diagnostic value for thyroid cancer.
