BACKGROUND The gold standard treatment for papillary thyroid carcinoma is total thyroidectomy and indications for microwave thermal ablation for primary thyroid cancers have not yet been clearly established However,some patients refuse surgery and others have no indication for it,for example patients under palliative care as in this case,or cannot undergo surgery,based on their *** indications are described in the most recent Korean,North American and European *** ablation,radiofrequency ablation,and microwave ablation are similarly safe and effective,so the choice should be based on the specific competences and resources of the pertaining *** indications are Percutaneous minimally-invasive techniques;they can be useful to stop disease progression and as an alternative to surgery in patients with contraindication or who refuse *** present a case of a thyroid papillary carcinoma with 17 mm effectively treated with microwave thermal ablation and without recurrence after one year of follow *** SUMMARY The authors present a case of a 71-years-old patient with a left lobe papillary thyroid carcinoma with 13 mm×17 mm×13 mm,with no indication for thyroid surgery given the context of another cancer in palliative *** thermoablation was performed on December *** months later he repeated computed tomography(CT)scan,which showed that the tumor had *** months after ablation he underwent a positron emission tomography/CT-fluorodeoxyglucose scan,which didn’t show any evidence of hypermetabolic tumor *** This case shows microwave thermoablation can be a safe and effective alternative to surgery in patients with no conditions to undergo surgery or when they refuse *** treating the tumor,with this minimally invasive technique,we are stopping its growth and avoiding disease progression.
