Background:
The impact of the 2015 ATA guidelines on treatment for differentiated thyroid cancer (DTC) in older adults is unclear.
Methods:
60,567 adults (age≥18) with low-risk DTC diagnosed between 2010 and 2018 were identified using SEER-21. Annual rates of total thyroidectomy (TT), hemithyroidectomy (HT), and active surveillance (AS) were analyzed using interrupted time series stratified by age: younger adults (18-64), older adults (65-79), and the super-elderly (≥80).
Results:
After 2015, annual rates of TT decreased by 2.6% and 1.9% in younger and older adults (p < 0.001), but increased by 4.6% in the super-elderly (p = 0.0126). Annual rates of HT increased by 2.6% and 1.7% in younger and older adults (p < 0.001), but decreased by 3.8% in the super-elderly (p = 0.0029). Older adults and the super-elderly were more likely than younger adults to undergo HT (aOR = 1.1, 95% CI: 1.03-1.2, p = 0.002 and aOR = 1.5, 95% CI: 1.3-1.7, p < 0.001) and AS (aOR = 1.5, 95% CI: 1.4-1.7, p < 0.001 and aOR = 6.5, 95% CI: 5.4-7.7, p < 0.001) when compared to TT following 2015.
Conclusions:
Treatment of DTC continues to vary significantly among age groups.

Synthesis and Regulation of Thyroid Hormones
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The...
