Value of ultrasound detection of calcification in the diagnosis of thyroid carcinoma / 中华普通外科杂志

ABSTRACT

ObjectiveTo investigate the clinical value of sonographic detection for calcification in diagnosis of thyroid carcinoma.MethodsClinical data of 3924 thyroid disease patients examined by ultrasonography and pathology at First Hospital of China Medical University were retrospectively reviewed to investigate the relationship between calcification, microcalcification, macrocalcification and peripheral calcification with thyroid carcinoma,the relationship between solitary nodule with calcification and multiple nodules with calcification with thyroid carcinoma and the relationship between calcification with thyroid carcinoma in different age groups. ResultsThe incidences of calcification,microcalcification in malignant and benign thyroid patients were 32.05％,6.50％ and 80.07％,51.53％,the incidences of calcification and microcalcification were significantly higher in malignant group than in benign group (P ＜ 0.01 ).The incidence of carcinoma in solitary nodules with calcification was 53.33％ while it was 22.2％ in multiple nodule group,the incidence of carcinoma in solitary nodules with calcification was significantly higher than that in multiple nodules (P ＜ 0.01 ).The incidence of carcinoma in solitary nodules with microcalcification was 74.1％ while in multiple nodule group it was 47.9％,the incidence of carcinoma in solitary nodules with microcalcification was significantly higher than that in multiple nodules ( P ＜ 0.01 ).The incidence of carcinoma younger than 70 years of age with caicification in different age groups was significantly different (P ＜ 0.05).In 40 and younger age group,the incidence of carcinoma with microcaicification was higher than that in over 44 years group (P ＜ 0.01 ).ConclusionsCalcification or microcalcification is considered to be a risk factor of thyroid carcinoma.Solitary nodules with calcification or microcalcification found in younger patients were more likely to coexist with thyroid carcinoma.
