Study of the Feasibility of Radiofrequency Ablation of Benign Thyroid Nodules

07 Oct, 2019 ,

University Hospital, Toulouse is conducting an Interventional study in 40 participants in order to  to evaluate the response rate to treatment of these symptomatic benign nodules with radiofrequency as an alternative to surgical treatment. The procedure includes an ultrasound with percutaneously radiofrequency ablation of benign thyroid nodule.

Thyroid benign nodules represent a major public health problem because they are very common (subclinical nodules were found in half of woman beyond 60 years). The main risk factors include age, female gender, parity, smoking and family history of thyroid nodules or thyroiditis. The assessment is based on biology, ultrasound and fine needle aspiration and intends to determine the benign nature (95%) or cancer (5%) of the nodules and if they are functional or not (toxic nodule).

Most benign nodules are asymptomatic but some of them because of their size and location can cause a functional disorder (compression or swallowing disorder) or aesthetic and psychological resounding.In current practice, these nodules are sometimes treated with surgery that impact on patient quality of life (need to take L-Thyroxine, difficulties related to the possible occurrence of complications like hypoparathyroidism or laryngeal paralysis) and socio-economic constraints especially when complications occur.

To limit the number of unnecessary and potentially risky surgeries, patients should therefore be well selected. If surgery is the preferred treatment of thyroid cancer, alternative techniques like radiofrequency seem interesting for benign nodules.
