Clinical Trial Summary

This clinical trial is to evaluate the effectiveness and the safety of high intensity focused ultrasound (HIFU) in the treatment of benign thyroid nodules.

Description:

This clinical trial is a prospective, multicentre, randomized, controlled study of high intensity focused ultrasound (HIFU) treatment of benign thyroid nodules. this study will include 240 patients with benign thyroid nodules that meet all ths the inclusion / exclusion criteria and will be randomly divided into two groups at 1: 1 ratio. Patients in the test group will be treated with high intensity focused ultrasound (HIFU), while patients in the control group will be actively observed and followed up by ultrasound examination. The primary objective of this clinical trial is to evaluate the efficacy of the test device in the treatment of benign thyroid nodules, and the secondary objective is to evaluate the safety of the test device in the treatment of benign thyroid nodules and the improvement of symptoms assessed by VAS score.

Eligibility

Inclusion Criteria:

1. Male or female patients older than 18 years and younger than 70 years

2. No history of neck irradiation

3. Normal thyroid function, serum calcitonin level, PTH and serum calcium at screening visit examination.

4. No abnormal cervical lymph nodes during screening visit examination.

5. The target thyroid nodule must meet all of the following conditions:

1. Single nodule, 2cm=max diameter=4cm

2. Causing appearance , pressure or swallowing symptoms

3. Composition of target nodule: solid or predominantly solid (solid area=80%)

4. Ultrasound imaging of target nodule assessed by 2017 ACR TI-RADS(=Grade 3), and proved benign by once FNA (bethesda category?); Ultrasound imaging of target nodule assessed by 2017 ACR TI-RADS( Grade 4), and proved benign by twice FNA (bethesda category?).

conditions shall be met:

1. Maximum diameter of these nodules is smaller than 1 cm and ultrasound imaging = Grade 3 assessed by 2017 ACR TI-RADS.

2. Only one nodule with 1cm= max diameter < 2cm, or/and no more than three nodule with max diameter <1cm. Ultrasonic images of all nodules=Grade 3 assessed by 2017 ACR TI-RADS.

Intervention

Device:
• Device: Echopulse (HIFU ablation)
High-intensity focused ultrasound (HIFU) is a non-invasive, non-invasive treatment method. The principle is to focus high-intensity ultrasound on the target area. Energy is absorbed by the target tissue and converted into thermal energy. The local temperature quickly reaches a maximum of 85 ° C. It induces coagulative necrosis of focus tissue cells, but does not damage the tissues surrounding the treatment targ
