RecruitingProcedurePrevalence and Predictors of Incidental Thyroid Carcinoma in Patients With Graves' Disease Undergoing Thyroidectomy.The prevalence of incidental thyroid cancer (ITC) in Graves' Disease (GD) patients undergoing thyroidectomy appears higher than historically believed, potentially exceeding 10% in large contemporary series, although significant variability exists. The presence of nodules is a strong predictor, while the roles of age, sex, and BMI require clarification. Most ITCs are papillary thyroid microcarcinoma(PTMCs) with generally favorable prognoses, but concerns about aggressiveness persist. The purpose of the present study is to accurately evaluate the prevalence of incidental thyroid carcinoma (ITC), including microcarcinomas, in a prospectively enrolled cohort of patients undergoing total thyroidectomy for Graves' disease, utilizing standardized pathological examination protocols and secondary outcomes including predictors and histopathological characteristics.
