甲状腺结节内钙化对甲状腺癌的诊断意义探讨

The Diagnosis Significance of Calcification in Thyroid Nodule to Thyroid Carcinoma

目的探讨甲状腺结节内钙化在甲状腺癌中的诊断意义。方法回顾性分析五华县人民医院在2004年7月至2009年12月期间收治的418例术前行B超检查诊断为结节性甲状腺肿伴钙化的患者的临床资料。结果 418例术前经超声检查为结节性甲状腺肿伴钙化的患者经术中术后病理确诊为甲状腺癌者有223例,占53.33%(223/418),其中乳头状癌179例,占甲状腺癌的80.27%;微小钙化在418例钙化中占64.59%(270/418),在乳头状癌中占73.74%(132/179);不同年龄组之间(≥45和<45)恶性钙化结节比例分别为39.25%、68.13%,差异有显著性意义(P<0.05)。结论术前B超检查能早期发现甲状腺钙化,其对于甲状腺癌的诊断具有重要意义。

Objective To discus the diagnosis significance of calcification in thyroid nodules to the thyroid cancer.Methods Retrospective analysis of Wuhua people＇s hospital in July 2004～December 2009 418 cases were treated during the preoperative diagnosis of B-ultrasound nodular goiter with calcification of the clinical data.Results 418 cases of preoperative ultrasound examination as nodular goiter with calcification in the patients from the surgical pathology of thyroid cancer were diagnosed 223 cases,accounting for 53.33%（223/418） ,of which 179 cases of papillary carcinoma,accounting for thyroid cancer,80.27%;micro calcification calcification in 418 cases accounted for 64.59%（270/418） in papillary carcinoma accounts for 73.74%（132/179） ;different age groups（≥45 and〈45） malignant calcification nodule ratio was 39.25%,68.13%,the difference was significant（P〈0.05） .Conclusion The preoperative B-ultrasonography to early diagnosis of thyroid calcification,its for the diagnosis of thyroid cancer is important.
