Thyroid Cancer in Patients with Hyperthyroidism

Abstract

ABSTRACT Background and objective Malignant tumors of the thyroid gland are the most common of the endocrine malignancies. Although, patients with thyroid cancer have high 5 years survival rate, thyroid cancer is the most seen cause of mortality among cancers of the endocrine organs. The incidence of thyroid cancer in hyperthyroid patients varies from 0.1 to 21% in the literature. We aimed in this study to analyze the frequency of coexisting thyroid cancer and hyperthyroidism in our experience. Results Total 230 patients, who were operated for hyperthyroidism without the suspicion of thyroid malignancy between January 2005 and September 2010 were included in our study. Toxic multinodular goiter, toxic adenoma and Graves’ disease were diagnosed preoperatively in 187, 16 and 27 patients respectively. Histopathological thyroid malignancy was detected in 13 patients (5.7%). Conclusion Thyroid cancer with variable incidence up to 21% should be remembered in differential diagnosis of hyperthyroid patients. How to cite this article Tastan B, Dogu A, Sevim Y.
