Objectives The current study sought to explore the effects of ultrasound (US)-guided radiofrequency ablation (RFA) on papillary thyroid microcarcinoma (PTMC) and influencing factors. Methods PTMC patients were assigned to observation (US-guided RFA) and control (surgical operation) groups. A series of operation-related indexes (operation time, intraoperative bleeding, wound closure time, hospital stay, and expenses), visual analogue scale score, lesion size, and thyroid function-related indexes (thyroid-stimulating hormone [TSH], free triiodothyronine*** [FT3], free thyroxine [FT4]), inflammatory factors, and thyroglobulin antibody (TgAb) were assessed and compared. After a 6-month follow-up period, the complications and recurrence were recorded, in addition to analyses of postoperative recurrence cumulative incidence and evaluation of recurrence risk factors. Results Operation-related indexes of the observation group were relatively decreased compared with the control group. In addition, the lesion volume in the observation group was lower compared to that in the control group at the 6th month after operation, whereas the volume reduction rate was higher. There were no significant differences in regard to thyroid function-related indexes in the observation group before/after operation. After operation, serum TSH levels and inflammatory factors, and TgAb levels were all diminished, while the FT3 and FT4 levels were both elevated in the observation group relative to the control group, and postoperative recurrence cumulative incidence was lower in the observation group. TSH and TgAb were established as the independent risk factors for recurrence after RFA in PTMC patients. Conclusions Our findings highlighted that US-guided RFA exhibits better efficacy, safety, and postoperative recovery and lower recurrence risk for PTMC.
