Résumé
Objective To study the clinical features of thyroid carcinoma and to explore the approach of early diagnosis for the disease.Methods The data of patients with thyroid carcinoma confirmed by pathology during January of 1999 to January of 2005 in the First Hospital affiliated to Shanghai Jiao Tong University were retrospectively reviewed,including clinical appearance,thyroid ultrasonography and radioisotope scanning.Results One hundred and twenty-seven consecutive patients,30 males and 97 females,mean age(48.9?13.6)years,were diagnosed with thyroid carcinoma by surgery and pathology.A total of 127 cases of thyroid carcinoma were included,which were 105 papillary thyroid carcinomas,14 follicular thyroid carcinomas,2 undifferentiated thyroid carcinomas and 6 medullary thyroid carcinomas.Thyroid ultrasonography findings showed the majority(85.1%)thyroid nodules were low echo nodules and the proportions of solid and mixed nodules were 81.8%and 17.4%,respectively.The proportion of cold nodules was 88.9% by radioisotope scanning.Mean values of serum triiodothyronine,thyroxine and thyrotropin were all within the normal range.Conclusion In the present study the thyroid carcinomas are predominant in females and the incidence of papillary thyroid carcinomas is very high.The diagnosis of thyroid carcinoma can not just depend on findings of ultrasonography,radioisotope scanning and serum thyroid hormone.
