Inclusion criteria

* Adult patients with cytologically confirmed papillary thyroid carcinoma with the longest diameter of less than or equal to 10 mms in T1aN0M0 clinical stage without metastases and without cytological signs of aggressivity AND * Patients objecting to both surgery and active surveillance

Exclusion criteria

* History of or active disease: neck irradiation, stroke, CV disease, CNS vascular malformation, any malignant disease, immunocompromised state, recurrent laryngeal nerve paresis, organ failure * extrathyroidal extension of tumor (including capsular) * pregnancy * lesion less than 5 mm close to the danger zone * safety margin could not be obtained (min 2mm) * uncontrolled hyperthyroidism * uncontrolled hypothyroidism * primary hyperparathyroidism * calcitonin or serum calcium over the threshold on a repeat blood test

Design outcomes

Primary

MeasureTime frameDescription
The number of patients without clinical evidence of a tumor on ultrasound and cytology on the treatment site24 monthsWe measure the number of patients without clinical evidence of a papillary thyroid microcarcinoma at the treatment site, evaluated with a (B-mode) ultrasound scan and a contrast-enhanced ultrasound scan of the whole tyroid and cytology reports from a fine needle aspiration from the site of the treatment at 24 months post-ablation.

Secondary

MeasureTime frameDescription
Number of patients with adverse effects24 monthsAdverse effects measured during and after the procedure
Volume reduction ratio24 monthsVolume reduction ratio: The volume reduction (initial volume minus final volume) compared to the original post-ablation volume, times 100. Volumes are measured on ultrasound. Length, width and depth is determined using the longest diameters on 3 perpendicular planes. Volume is reported in mL, calculated using the ellipsoid volume formula: (length x width x depth) x 0.524.
