Background
This study aimed to investigate outcomes in the same cohort of patients with papillary thyroid carcinoma (PTC) risk-stratified according to the Japan Association of Endocrine Surgery (JAES) and American Thyroid Association (ATA) guidelines.
Methods
A total of 1044 patients with PTC who underwent initial thyroidectomy at Yokohama City University Medical Center between January 2000 and June 2022 were included.
Results
According to the JAES guidelines, 480 (46%), 386 (37%), and 178 (17%) patients were classified as low, intermediate, or high risk, respectively. Furthermore, according to the ATA guidelines, 590 (57%), 261 (25%), and 193 (18%) patients were reclassified as low, intermediate, or high risk, respectively. Among 1044 patients with PTC, the 10-year cause-specific survival (CSS) rates of patients with JAES low and intermediate risk were 99.7 and 98.6%, respectively, and there was no statistically difference (p = 0.096). However, the 10-year CSS rates of patients with ATA low and intermediate risk were 100 and 99.5%, respectively (p = 0.007). Among 1001 patients with M0 PTC, the 10-year distant metastasis-free survival (DMFS) rates of patients with JAES intermediate and high risk were 94.2, and 76.7%, respectively (p < 0.001). However, the 10-year DMFS rates of patients with ATA intermediate and high risk were 88.1 and 86.6%, respectively (p = 0.233), and there was no statistically difference.
Conclusions
Both JAES and ATA risk classifications properly stratified the PTC patients. Furthermore, the ATA risk classification more precisely extracted patients with better and worse prognoses.
