Abstract
INTRODUCTION: To assess the rate of thyroid cancer and mortality rate in a cohort of patients who received RAI131 treatment for hyperthyroidism and to report the index cases' characteristics and management MATERIAL AND METHODS: A cohort of 264 patients who received RAI131 treatment for different causes of thyrotoxicosis were followed up over a period of 18 years (1996-2014) by physical exam, radiological evaluation and serial thyroid function tests.
RESULTS: During the follow up period, three cases of thyroid cancer were identified. The prevalence of thyroid cancer is 1.136% of cases who received RAI131. The relative risk is 378.79 (95% CI: 76.8 < RR < 1868.23). P value is < 0.0000004 and the SMR is 1.99/1000.
CONCLUSIONS: The prevalence of thyroid cancer is 1.136% in the cohort of patients treated with RAI131. Despite no direct cause effect relationship between RAI and thyroid cancer could be established, these cases highlights the importance of life long surveillance of patients who receive RAI131.
