Treatment for indeterminate thyroid nodules using myo-inositol and selenium

Use of Myo-inositol and Selenium in Patients with Indeterminate Thyroid Nodules (TIR3A)

Not applicable Interventional Regina Elena Cancer Institute · NCT06736015

This study is testing if a six-month treatment with a supplement of myo-inositol and selenium can help reduce the size and improve the elasticity of certain thyroid nodules in patients.

What this trial studies

This clinical trial investigates the effects of a six-month treatment with a supplement containing myo-inositol and selenium on the size and elasticity of indeterminate thyroid nodules classified as TIR3A. The study aims to determine if this treatment can reduce nodule size and cellular proliferation, assessed through ultrasound and immunocytochemistry. Participants will be randomly assigned to receive the supplement or standard care, with follow-up evaluations to assess changes in nodule characteristics. The trial is designed to provide insights into a potential non-invasive treatment option for patients with low-risk thyroid nodules.

Who should consider this trial

Good fit: Ideal candidates for this study are adults over 18 years old with thyroid nodules classified as TIR3A based on cytological evaluation.

Not a fit: Patients with diagnosed thyroid malignancies or those requiring treatment for abnormal thyroid hormone levels will not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a non-invasive option to reduce the size and risk of progression of indeterminate thyroid nodules.

How similar studies have performed: While there have been studies on myo-inositol and selenium for thyroid conditions, this specific approach for TIR3A nodules is novel and has not been extensively tested.
