Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

Multicentre 1:1 randomized clinical trial where patients are allocated to either radiofrequency ablation (RFA) or radioactive iodine (RAI) (I-131). Patients who are not suitable for randomization (e.g. no informed consent or contra-indication for RFA) are asked for consent to participate in a prospective cohort where participants are asked to fill out questionaires and data is collected.
Primary Study Purpose

TREATMENT

Blinding Strategy

NONE

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Radiofrequency ablation

Patients allocated to the radiofrequency ablation (RFA) arm will undergo RFA under local anaesthesia with the moving-shot technique.

Group Type EXPERIMENTAL

Radiofrequency ablation

Intervention Type DEVICE

Ultrasound-guided radiofrequency ablation of the solitary autonomous thyroid nodule.

Radioactive iodine, study protocol

Patients allocated to this arm will undergo treatment with radioactive iodine (I-131) according to a standardized dose-calculation.

Group Type ACTIVE_COMPARATOR

Radioactive iodine

Intervention Type DRUG

I-131 according to standardized doses-calculation.

Radioactive iodine, cohort

This group contains patients who are not randomized and have given informed consent undergo treatment with radioactive iodine (I-131) according to local standard (e.g. fixed dose or dose-calculation based on iodine uptake and thyroid nodule mass).

Group Type OTHER

Radioactive iodine

Intervention Type DRUG

I-131 according to local standard.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Age \> 18 years
* Hyperthyroidism or subclinical hyperthyroidism caused by a solitary hyperactive thyroid nodule (HTN), either located in an otherwise normal thyroid gland, or in a multinodular goitre (MNG), with a diagnosis based on the following characteristics:

* Blood TSH level below the lower limit of normal, and associated with either normal or elevated FT4 and FT3 levels
* Anti-TSH antibody negative
* Solitary HTN confirmed by a diagnostic I-123 scintigraphy, corresponding with a well demarcated thyroid node on ultrasound, cystic degeneration \< 75%, nodule size \<50 mm.
* Treatment with RAI indicated, and eligible for RFA treatment
* Signed informed consent Patients who are ineligible for randomization due to unsuitability for RFA, may be eligible for the RAI cohort group.

Exclusion Criteria

* Multifocal HTN
* HTN \> 50 mm
* Presence of a medical device susceptible to disturbances caused by RFA generated currents
* Patients with physical or behavioural disorders that preclude safe isolation in radiation protection rooms, or safe RFA procedure under local anesthesia
* Patients with dysphagia, oesophageal stenosis, active gastritis, gastric erosion, a peptic ulcer or impaired gastro-intestinal motility
* Uncorrectable haemorrhagic diathesis
* Pregnant or breastfeeding women
