Primary Outcome Measures

Name	Time	Method
disease-free survival	more than 5 years	disease-free survival calculated from treatment initiation to disease progression or the last follow-up date
disease progression	more than 5 years	cervical lymph node metastases, recurrent tumors and persistent tumors

Secondary Outcome Measures

Name	Time	Method
complications	1 week	complications after surgery or ablation
cost	1 week	The ablation cost included preoperative examinations, treatment, local anesthesia and ablation needle costs. The lobectomy cost included preoperative examinations, treatment, general anesthesia, hospital bed, nursing and postoperative medication
hospitalization	1 week	hospitalization for surgery or ablation
procedure time	1 hour after treatment	Ablation procedure time was defined from US evaluation for the design of insertion way to treatment terminated. Lobectomy procedure time was defined from incision to closure, not including the anesthesia time.
estimated blood loss	1 hour	estimated blood loss after surgery or ablation
