Summary
Brief summary (as posted)
There is no scientific data on post-thermal ablation cytological aspects, but treated nodules that grow back significantly after a procedure justify a new cytology in order not to ignore a neoplastic process. The EU-TIRADS classification usually used to stratify the risk of cancer (and to justify a fine needle aspiration biopsy) of thyroid nodules is not validated for nodules treated by thermal ablation (TA) (post-RF nodules). However, these nodules often acquire ultrasound criteria of suspicion making it necessary to develop an ultrasound stratification of the risk of malignancy specific to nodules treated by TA. The objective of this work is to describe the ultrasound and cytological aspects of these treated nodules by performing a systematic assessment at 3 years after thermal ablation including systematic neck ultrasound and fine needle aspiration biopsy. Thus, an ultrasound and cytological atlas (Bethesda classification 2017) of nodules treated by thermal ablation will be constituted.

- description
- The study population is a monocentric cohort of patients who underwent thermoablation treatment for benign thyroid nodules 3 years ago. These patients aged \>18 years-old were carriers of a benign but troublesome thyroid nodule before thermal ablation, either unique or "dominant", i.e. associated with one or more other non-significant nodules (\<20 mm) that were subjected to simple ultrasound surveillance. Patients refused, after clear and fair information, surgical management of their nodule. On average, 2 patients have been treated for TA per week in the Thyroid Disease and Endocrine Tumor Department since 2016. Patients systematically benefit from annual clinical and ultrasound monitoring as part of their follow-up in our Department.
