What this trial studies

This observational study investigates the relationship between iodine nutritional status and clinical characteristics of thyroid cancer. It involves a prospective cohort of patients who underwent thyroid surgery in various regions with differing iodine levels from 2012 to 2019. The study aims to analyze how regional iodine nutrition influences the pathological types, clinical features, and prognosis of thyroid cancer. Patients are recruited from selected sub-centers in high and moderate iodine areas, ensuring a comprehensive understanding of iodine's role in thyroid cancer.
