About this trial

This study is a multicenter randomized controlled trial conducted in Korea. A parallel, two-group randomized design will be with thyroid stimulating hormone suppression therapy group(low TSH group; intervention) is different from the wIthout thyroid stimulating hormone (TSH) suppression therapy group(high TSH group; control).

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Thyroid nodule of 1.0 cm or less confirmed as Bethesda category V (suspicious for PTC) or VI (PTC) based on cytopathological examination, or Bethesda category III (atypia of undetermined significance) with a confirmed BRAF V600E mutation.

Patients with no evidence of distant metastasis, cervical lymph node metastasis, recurrent laryngeal nerve invasion, or tracheal invasion. Additionally, no evidence of extrathyroidal extension (ETE) should be present, and the tumor must not belong to high-risk subtypes of PTC (e.g., diffuse sclerosing, columnar cell, or solid subtype).

Non-pregnant women of childbearing potential (confirmed by medical history taking)

Disqualifiers

Hyperthyroidism

Myocardial infarction or cerebrovascular accident within the last three months.

Diseases with limited life expectancy or potentially impairing the patient's ability to comply with at least five years of treatment or follow-up.

Trial design

Design model

Parallel

Treatments tested in this trial

  • Levothyroxin

    Drug

    During the five-year study intervention period, thyroid hormone (oral administration) supplementary doses are determined according to a dose-adjustment protocol established for the group's target TSH range.

Treatment groups

578 Participants
are divided into 2 treatment groups
Group A: low TSH groupExperimental treatment 1 intervention
Group B: high TSH groupExperimental treatment 1 intervention

Trial outcomes

Primary outcomes

1

Rate of Disease progression

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.

Time frame
at 3,5years after enrollment

Secondary outcomes

1

Disease free survival

As the time interval from enrollment to either disease progression or all-cause mortality, whichever occurs first.

Time frame
at 3,5years after enrollment
2

Disease specific survival

As the time from the date of enrollment to disease-specific mortality.

Time frame
at 3,5years after enrollment
3

Overall Survival

As the time from the date of enrollment to death.

Time frame
at 3,5years after enrollment
4

Target-TSH-level achievement rate

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.

Time frame
at 3,5years after enrollment
