The value analysis of tumor deposit in the comprehensive evaluation before differentiated thyroid cancer RAI therapy

TD should be considered as a prognostic factor in the postoperative RAI treatment. We propose incorporating TD into the TNM staging and the ATA initial risk stratification system as a reference, suggesting that TD-positive patients in N1a stage be classified as N1b stage; patients in TNM stage I be classified as TNM stage II ;and the ATA intermediate risk patients be classified as the ATA high risk.
