About

Papillary thyroid micro-carcinoma (PTMC) generally demonstrates favorable prognosis. However, the potential risk of disease progression requires careful therapeutic consideration. Radiofrequency ablation (RFA) has garnered attention as a minimally invasive treatment option for patients with PTMC who choose to decline both surgical resection (SR) and active surveillance. However, comprehensive comparative studies evaluating RFA versus surgery regarding long-term oncological efficacy, quality-of-life, and cost-effectiveness in multicenter cohorts remain warranted. To compare the oncological outcomes, quality of life, and cost-effectiveness between RFA and SR for low-risk PTMC over 10 years' follow-up.
