Abstract

Abstract:

In recent years， the clinical active surveillance （AS） for low-risk papillary thyroid carcinoma has been approached with extreme caution by both domestic and international guidelines， and there has even been controversy. The "2025 Korean Thyroid Association clinical management guideline on active surveillance for low-risk papillary thyroid carcinoma" comprehensively delineate the assessment and screening of the appropriate population for AS in low-risk papillary thyroid carcinoma. The guidelines recommend clinical management protocols during AS， and outline the indications for surgical intervention during the AS period. Based on relevant domestic and international guidelines， a comparative analysis is now conducted on the characteristics of patients with AS who are suitable for treatment at the age of 19 or above， the follow-up strategy dominated by ultrasound examinations， and the timing of surgical intervention in the event of tumor progression during AS， with the aim of offering references for clinical practice.

Key words: Thyroid neoplasms, Active surveillance, Surgical treatment, Follow-up
