Calcified thyroid nodules and thyroid carcinoma / 中华普通外科杂志

ABSTRACT

Objective To investigate the calcification of thyroid nodules detected by ultrasound and its relation with thyroid carcinoma.Methods Four thousand one hundred and eighty-six cases of thyroid disease were surgically treated during a period of five years.Retrospective analysis was made to compare preoperative color Doppler ultrasound and postoperative pathology.Results The incidence of calcification,non-microcalcification,and microcalcification were significantly higher in thyroid carcinoma than that in benign diseases(P＜0.05).For predicting thyroid cancer,microcalcification was more significant than non-microcalcification(P＜0.01).There was a significant difierence in the microcalcification between the different age groups(2.4%for patients of 45 and older,16.8%for patients younger than 45;P＜0.05)There was no difference in the calcification between male and female groups(P＞0.05);There was a significant difierence in malignant calcified nodules between difierent nodule groups(70.7%for patients of solitat'y.49.1%for patients of muhipleP＜0.05).Conclusion Microcalcifications in the thyroid is related to thyroid cancer.especially to micro-papillary carcinoma.
