|---|---|---|---|
| Primary | Rate of Disease progression | at 3,5years after enrollment | The rate of disease progression will be assessed as the proportion (%) of patients with biopsy-confirmed recurrence, based on suspicious findings identified through thyroid (neck) ultrasound performed at 6- to 12-month intervals. |
| Secondary | Disease free survival | at 3,5years after enrollment | As the time interval from enrollment to either disease progression or all-cause mortality, whichever occurs first. |
| Secondary | Disease specific survival | at 3,5years after enrollment | As the time from the date of enrollment to disease-specific mortality. |
| Secondary | Overall Survival | at 3,5years after enrollment | As the time from the date of enrollment to death. |
| Secondary | Target-TSH-level achievement rate | at 3,5years after enrollment | Comparison of between the low-TSH and high-TSH groups at each follow-up visit regarding the presence or absence of thyroid hormone use and its dosage, considering body weight and medication adherence, in order to achieve the target TSH concentration. |
| Secondary | Incidence of complications | at 3,5years after enrollment | Comparison of the incidence of complications at each follow-up visit between the low-TSH and high-TSH groups. |
| Secondary | Safety evaluation | at 3,5years after enrollment | Incidence and grade of adverse events. |
| Secondary | Risk Factors for Thyroid Cancer Recurrence | at 3,5years after enrollment | The study will assess the relationship between thyroid hormone levels (TSH, free T4, total T3 or free T3) and potential risk factors for recurrence, including: * Demographic factors: sex, age, smoking status, BMI * Pathologic features: tumor stage, size, extrathyroidal extension * Genetic mutations: BRAF, TERT promoter mutations The analysis will identify factors, adjusted for thyroid hormone levels, significantly associated with recurrence risk. Statistical methods such as Generalized Estimating Equations (GEE), Interval Censored Survival Analysis, and Cox-proportional hazards regression will be used for evaluation. |
| Secondary | Predictors of Treatment-Related Complications Based on Thyroid Hormone Levels | at 3,5years after enrollment | The study will assess the relationship between thyroid hormone levels (TSH, free T4, total T3 or free T3) and risk factors for treatment-related complications (e.g., tachycardia, reduced bone mineral density). Risk factors include: * Demographic factors: sex, age, smoking, BMI, weight, blood pressure, concurrent medications, menopausal status, diabetes, asthma/COPD, rheumatic diseases * Cholesterol levels: Total cholesterol, LDL, HDL * ECG and Bone Mineral Density (BMD) The analysis will evaluate the association between these factors and treatment-related complications, adjusting for thyroid hormone levels. Incidence rates of complications at follow-up will be compared using Chi-square, Fisher's exact test, or Generalized Estimating Equations (GEE). |
| Secondary | Predictors of TSH levels and proper thyroid hormone dosage | at 3,5years after enrollment | This study will identify factors that predict changes in thyroid hormone levels (TSH, free T4, total T3, or free T3) and predict the required thyroid medication dosing. The factors under include: * Demographic Factors: Sex, age, comorbidities, smoking status, body mass index (BMI), weight, and current medications * Thyroid Function: Pre-existing thyroid disorders, and the presence of thyroiditis The analysis will evaluate the association between these factors and changes in thyroid hormone levels, as well as predict the necessary adjustments in thyroid hormone dosing, using multiple regression analysis. |
| Secondary | Test interval for efficient diagnosis of recurrence | at 3,5years after enrollment | To analyze the duration until recurrence and the interval between examinations. |
