Registry - Use of a High Intensity Focused Ultrasound (HIFU) in Patients With Non-malignant Thyroid Nodules.

NCT ID: NCT02246504

Last Updated: 2019-09-17

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: NA
• Total Enrollment: 20 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2012-10-09
• Study Completion Date: 2017-03-07

Brief Summary

The purpose of this study is to evaluate thyroid nodule's volume, structure and vascularisation changes following HIFU therapy assessed by ultrasonography

Detailed Description

HIFU treatment will be performed under conscious sedation under the supervision / responsibilities of an anesthetist.

A maximum of 2 HIFU sessions per nodule will be performed per patient. The decision to retreat the patient will be taken at 1 month post-HIFU or later.

Follow-up after HIFU treatment

D1 after HIFU session:

• Indirect laryngoscopy to check vocal cord mobility.

D7 after HIFU session

• Clinical examination (skin, local symptoms, oedema, voice….),
• Ultrasonography and Power Doppler,

M1 after HIFU session

• Clinical examination (skin, local symptoms, oedema, voice….),
• Ultrasonography and Power Doppler,

M3 after HIFU session

• Clinical examination (skin, local symptoms, oedema, voice….),
• Ultrasonography and Power Doppler Decision for an additional HIFU course to improve volume reduction.

In case of a second HIFU session D7b, M1b and M3b, M6b, M9b, M12b, M18b, M24b and M36b will be performed

M6 after last HIFU session

• Clinical examination (skin, local symptoms, oedema, voice….),
• Ultrasonography and Power Doppler
• TSH
• Free T4
• Antithyroid peroxidase antibodies
• Calcemia and PTH (in case of bilateral treatment or in case previous thyroid surgery)

M9 after HIFU session

• Clinical examination (skin, local symptoms, oedema, voice….),
• Ultrasonography and Power Doppler

M12 after last HIFU session

• Clinical examination (skin, local symptoms, oedema, voice….),
• Ultrasonography and Power Doppler
• TSH
• Free T4
• Antithyroid peroxidase antibodies
• Calcemia and PTH (in case of bilateral treatment or in case previous thyroid surgery)

M18, M24, M36 after HIFU session

• Clinical examination (skin, local symptoms, oedema, voice….),
• Ultrasonography and Power Doppler

Eligibility Criteria

Inclusion Criteria

• Male or female patient 18 years or older.
• Patient presenting with at least one thyroid nodule with no signs of malignancy:
