title: [Is hyperthyroidism often present in patients with thyroid differentiated carcinoma?].
abstract: The coexistence of thyroid cancer and hyperthyroidism is confirmed by many authors. It appears that the frequency of both disease can be greater as a result of lack of proper and penetrating biopsy diagnosis and of qualification to surgery treatment patients with hyperfunctional goiter and Graves disease, especially coexisting with nodes. The aim of our study was estimation of occurrence of hyperthyroidism in the patients with thyroid differentiated cancer. We examined group of 217 patients with diagnosed thyroid differentiated cancer, 20 patients (9.1%) of them were earlier hyperthyroidism diagnosed. 17 of them were hyperfunctional nodular goiter diagnosed and three as Graves disease, confirmed by presence of anti-TSH receptor antibodies (TRAK). Before thyroidectomy ultrasonography showed nodular goiter in 17 patients and hypoechogenic goiter with nodules in 3 patients. After thyroidectomy at the hyperthyroid patients in 16 papillary thyroid cancer and in 4 follicular thyroid cancers were diagnosed. The frequency of coexistence of cancer and hyperthyroidism in our material amounted for 9.1%. The results of our observation do not diverge from facts given in world literature and is point out the need for precise analysis of patients with hyperthyroidism and of proper qualification to surgery treatments changes suspected to be malignant process.
