Experience of Radiofrequency Ablation Treatment of Thyroid Papillary Micro-carcinoma Under Ultrasound Guidance
Abstract：Objective To summarize the clinical experience of radiofrequency ablation ( RFA) treatment of thyroid papillary micro -carcinoma under ultrasound guidance .Methods (1)9 patients, with 11 lesions, were recruited with ultrasonography diagnosis of thyroid micro-carcinoma (less than 10 mm in diameter), who were anxious about the mass but non -acceptance of surgery.(2)Core needle his-tological biopsy was done before RFA;then the lesions were treated by RFA under ultrasound guidance .All the patients were followed up by ultrasound scan.Results (1)All patients recovered with no FRA related complications .(2)Seven lesions was pathologically diagnosed as thyroid papillary carcinoma , and in four lesions tumor cells weren′t pathologically found .( 3 ) All cases were followed up from 12 to 18 months.Post ablated lesions became smaller and smaller during follow -up, and diminished within 6 months.There was no abnormal ima-ging which was considered recurrence in both thyroid and lymph nodes .Conclusion (1)RFA could be considered as a safe and effective method in treating papillary micro -carcinoma of thyroid.(2)Due to the advantages of safety and minimally invasion of RFA , thyroid le-sions, which were highly suspected malignant, was one of the indications of RFA, even if there was no pathological confirmation.(3)Long time follow-up are needed to observe the effect and side -effect of FRA.
