About this trial

The goal of this observational study is to learn if radiofrequency ablation (RFA), a minimally invasive thermoablation technique, can safely reduce symptoms and improve quality of life in adults with symptomatic benign thyroid nodules or autonomously functioning thyroid nodules.

The main questions it aims to answer are:

* Does RFA improve health-related quality of life (HRQoL) as measured by the ThyPRO-39 questionnaire? * Does RFA effectively reduce nodule volume and related symptoms (compressive or cosmetic)?

Participants will:

* Undergo a radiofrequency ablation procedure of the thyroid nodule performed under ultrasound guidance in an outpatient setting. * Complete quality of life questionnaires (ThyPRO-39) before treatment and at follow-up visits.

Attend follow-up visits at 1, 3, 6, and 12 months with:

* Ultrasound assessments of the thyroid nodule * Symptom and cosmetic scoring * Blood tests to monitor thyroid function * Safety checks for possible complications

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

> 18 years old

'Eastern Cooperative Oncology Group' (ECOG) performance status of 0 or 1

Symptomatic benign thyroid nodules with compressive/cosmetic complaints OR autonomously functioning thyroid nodules with subclinical hyperthyreosis or thyrotoxicosis proven on scintigraphy.

No cutoff in nodule size.

Disqualifiers

<18y

Purely cystic nodule

Severe comorbidity which limits the further life expectancy of the patient to < 2 years (opinion of the physician)

Malignancies <2 years ago except for non-melanoma skin cancer and non-muscle invasive bladder cancer.

Trial population

Study participants will be selected from the following Belgian hospitals: Ghent University Hospital, University Hospital Leuven, AZ Sint Jan Brugge.

Case-only

Time perspective

Prospective

Treatments tested in this trial

  • Percutaneous radiofrequency ablation

    Device

    RFA uses an electric field, produced by a radiofrequency generator connected to an internally cooled electrode needle, leading to frictional agitation at the ionic level and to heat generation (Joule effect). The electrode is introduced under US guidance into the target nodule, and a continuous repositioning of the applicator ("moving shot" or "multiple overlapping shot" technique). The localized heating causes necrosis and shrinkage of the thyroid nodule without damaging surrounding tissues. The appearance of hyperechoic signals close to the electrode tip indicates the development of tissue changes and air formation, while a steep rise in tissue impedance demonstrates the achievement of tissue necrosis

Trial outcomes

Primary outcomes

1

Health related Quality Of Life (HRQoL)

HRQoL will be assessed by the change in Thyroid-Related Patient-Reported Outcome 39 (ThyPRO-39) score from baseline to 1-year follow-up. The ThyPRO-39 is a thyroid-specific quality of life instrument covering 13 domains of QoL validated for patients with benign thyroid disease. The ThyPRO-39 includes scales assessing the following: goiter symptoms, eye symptoms, hyperthyroid symptoms, hypothyroid symptoms, tiredness, cognitive complaints, anxiety, depressivity, emotional susceptibility, impaired social life, impaired daily life, appearance, and overall QoL. Each item is rated on a Likert scale (0-4) from 0 = "no symptoms/problems" to 4 = "severe symptoms/problems." Scores are then transformed to yield 13 0-100 scales, where a higher score indicates worse health-related QoL

Time frame
From baseline (before treatment) to 12 months after the radiofrequency ablation procedure, with assessments at baseline, 1 month, 3 months, 6 months, and 12 months

Secondary outcomes

1

Symptom score

Registered on a Visual Analog Scale (VAS), ranging from 0 to 10, where 0 indicates "no symptoms" and 10 indicates "worst imaginable symptoms".

Time frame
From baseline (before treatment) to 12 months after the radiofrequency ablation procedure, with assessments at baseline, 1 month, 3 months, 6 months, and 12 months.
2

Cosmetic score

Assessed during physical examination; ranging from 1 to 4, where 1 graded as no palpable mass, 2 graded as a palpable mass without cosmetic issue, 3 graded as a cosmetic problem on swallowing, and 4 as a readily detected cosmetic problem.

Time frame
From baseline (before treatment) to 12 months after the radiofrequency ablation procedure, with assessments at baseline, 1 month, 3 months, 6 months, and 12 months.
3

Number of Participants with Treatment-Related Adverse Events

Safety will be measured based on the presence of minor or major complications. Major and minor complications are those defined by the Society of Interventional Radiology.

Time frame
From baseline (before treatment) to 12 months after the radiofrequency ablation procedure, with assessments at baseline, 1 month, 3 months, 6 months, and 12 months.
4

Volume Reduction Rate (VRR)

Calculated as VRR (%) = (initial volume - final volume) ÷ initial volume × 100

Time frame
From baseline (before treatment) to 12 months after the radiofrequency ablation procedure, with assessments at baseline, 1 month, 3 months, 6 months, and 12 months.
