Anaplastic Thyroid Carcinoma

Thyroid cancers represent about 1% of all human cancers. Differentiate thyroid carcinomas (DTCs), papillary and follicular cancers, are the most frequent forms, instead Anaplastic Thyroid Carcinoma (ATC) is estimated to comprise 1-2% of thyroid malignancies and it accounts for 14-39% of thyroid cancer deaths. The annual incidence of ATC is about one to two cases/million, with the overall incide...

Anaplastic transformation of differentiated thyroid carcinoma.

Anaplastic thyroid cancer (ATC) is one of the most aggressive malignancies that arise from transformation of pre-existing differentiated thyroid cancer (DTC). However, the carcinogenic mechanism of anaplastic transformation remains unclear. We describe a case for huge goiter diagnosed as papillary thyroid carcinoma, which underwent thyroidectomy. The final histology showed anaplastic transforma...

CT evaluation of anaplastic thyroid carcinoma.

CT findings in 19 patients with anaplastic thyroid carcinoma were compared retrospectively with pathologic findings and the results of palpation. The carcinoma appeared as a large mass of low attenuation accompanied by dense calcification in 58% of the patients; there was necrosis in 74%. Often, adjacent structures were infiltrated. CT correctly showed tumor invasion of the carotid artery (7/7)...

Diagnosis and Treatment of Anaplastic Thyroid Carcinoma

Anaplastic thyroid carcinoma (ATC) is a poorly differentiated thyroid cancer. It cannot uptake iodine or synthesis thyroglobulin. The incidence is low; about 2% 5% of thyroid cancer. The peak age incidence is 60 70 years and it is more common in females (55% 77% of all patients). In recent years, the incidence has declined; however, it may be higher in areas of endemic goiter. ATC may occur wit...
