AI summary: who the study is looking for
From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.
The trial is looking for adults with Graves' disease who are scheduled for a total thyroidectomy. It studies how often a small thyroid cancer is found by chance in the removed thyroid.
- Age
- 18 to 75 years
- Sex
- All sexes can join.
- Disease stage
- Confirmed Graves' disease with a reason for total thyroidectomy, such as relapse after antithyroid drugs, drug intolerance, a large goiter, a suspicious nodule or severe eye disease.
- Earlier treatment
- No previous thyroid surgery and no previous neck irradiation.
- Biomarker or test result
- Graves' disease shown by blood tests (low TSH, high free T4 and/or T3) and/or a positive TSH receptor antibody (TRAb) test.
Main reasons for not taking part
- Previous thyroid surgery
- Previous neck irradiation
- Thyroid cancer already confirmed by needle biopsy (Bethesda V or VI)
- Surgery mainly for a reason other than Graves' disease
- Surgery smaller than a total thyroidectomy, such as lobectomy or subtotal thyroidectomy

- Original description
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.Read full original descriptionShow less
Prevalence and Predictors of Incidental Thyroid Carcinoma in Patients With Graves' Disease Undergoing Thyroidectomy: A Prospective Study.
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.
Inclusion: Age 18 years or older; Confirmed diagnosis of Graves' disease based on clinical features (e.g., diffuse goiter, ophthalmopathy if present) and biochemical evidence (suppressed TSH, elevated free T4 and/or T3) and/or positive TSH receptor antibody (TRAb) test; Indication for total thyroidectomy for Graves' disease, based on established guidelines:; Relapse or persistence of hyperthyroidism after a course of antithyroid drugs (ATDs); Intolerance or adverse reaction to ATDs. Patient preference for surgery over radioactive iodine (RAI) or long-term ATDs. Presence of a large goiter causing compressive symptoms. Coexisting suspicious thyroid nodule(s) on preoperative evaluation. Moderate to severe active Graves' ophthalmopathy where RAI is relatively contraindicated; Patient is scheduled for total thyroidectomy (near-total or subtotal thyroidectomy patients will be excluded); Ability and willingness to provide written informed consent; Ability to understand study procedures and requirements.
Exclusion: Previous thyroid surgery; Previous neck irradiation; Preoperative diagnosis of thyroid malignancy confirmed by fine-needle aspiration (FNA) cytology (Bethesda V or VI) , the focus is on incidental carcinoma; Inability to provide informed consent (e.g., due to cognitive impairment); Patients undergoing thyroidectomy primarily for reasons other than Graves' disease (e.g., primary indication is large non-toxic MNG); Age less than 18 years; Patients undergoing less than total thyroidectomy (e.g., lobectomy, subtotal thyroidectomy).
