[en] Thyroid cancer is an uncommon oncological disease. It represents a group of various malignant epithelial tumors with different therapeutic procedures and diverse prognosis. Epidemiologically most significant is differentiated thyroid cancer with a favourable prognosis. Due to a good interdisciplinary management up to 90% of patients reach permanent remission of the disease. On the basis of long-term results of different therapeutic procedures european and american consensus for the treatment of differentiated thyroid cancer was created in 2006. In Slovakia it is also necessary to standardize diagnostic and therapeutic procedures in the management of this disease. (author)
