Summary

1. The incidence of differentiated thyroid cancer is increasing in Korea. A significant number of them experience severe hypothyroidism in preparation for radioactive iodine (RAI) therapy after total thyroidectomy. 2. Because the function of thyroid hormone is closely linked with lipid and glucose metabolism, overt hypothyroidism after thyroid hormone withdrawal during RAI therapy may induce the changes of metabolic parameters. 3. We investigate the effects of thyroid hormone withdrawal on metabolic and cardiovascular parameters during radioactive iodine therapy in differentiated thyroid cancer.

Clinical Details

Official title: Effects of Thyroid Hormone Withdrawal on Metabolic and Cardiovascular Parameters During Radioactive Iodine Therapy in Differentiated Thyroid Cancer

Study design: Observational Model: Case-Only, Time Perspective: Prospective

Primary outcome: Changes of metabolic parameters

Secondary outcome: Changes of bone turnover markers

Detailed description: 1. Study design measurement of various parameters during hypothyroid state (before 1 month, the day and after 1 month of RAI therapy) 2. Measurements 1. Measurement of metabolic and cardiovascular parameters

- glucose profiles : HbA1c, fasting glucose level

- lipid profiles : free fatty acid, total, LDL-, HDL-, cholesterol,

triglyceride

- adipocytokines : retinol binding protein(RBP)

- 4, leptin, resistin, adiponectin

- markers of endothelial and cardiac function : high-sensitivity C-reactive

protein(hsCRP), homocystein, B-type natriuretic peptide(BNP)

- bone turnover markers : CTX, bone ALP

2. Scoring of symptoms and signs of hypothyroidism (Zulewski score)

- symptoms

- physical signs
