Details and patient eligibility

About

• To find out the gap between real-world clinical practice and guideline recommendations in initial management of DTC patients
• To observe the characteristics of patients who achieved and did not achieve TSH target value after one year follow-up
• To assess response to initial therapy in patients who undergo total or near-total thyroidectomy and RAI remnant ablation after one year follow-up (according to an modified dynamic risk stratification system)
• To observe the recurrence status after one year follow-up

Full description

Multi-center, prospective, registry study

2000 DTC patients undergo the first-time thyroidectomy and identified as intermediate or high risk of recurrence will be recruited. Doctors can treat the patients based on disease conditions. Investigators will record data which are related to study endpoints.

Primary endpoint(s):

1. Proportion of patients who underwent total/near-total thyroidectomy
2. Proportion of patients who were treated by 131I after undergoing total/near-total thyroidectomy
3. Proportion of patients who achieved serum TSH target value
4. Proportion of patients who did not achieve serum TSH target value although they were treated by TSH suppression therapy

Secondary endpoint(s):

1. Time to achieve serum TSH target value
2. Dosage of L-T4 for patients who achieved and did not achieve serum TSH target value
3. Dosage of L-T4 per kilogram of body weight for patients who achieved and did not achieve serum TSH target value
4. Proportion of excellent response/Acceptable response/Biochemical incomplete response/Structural incomplete response to initial management in patients who undergo total or near-total thyroidectomy and RAI remnant ablation after one year follow-up
5. Recurrence rate after one year follow-up
6. AEs related to L-T4 (or thyroid tablet)treatment

Enrollment: 2,000 estimated patients

Sex: All

Volunteers: No Healthy Volunteers

4. Patients who have Chinese nationality
5. Patients who have signed an informed consent form

Exclusion criteria

5. Legal incapacity or limited legal capacity
6. Unwilling to be followed up
