Background: With a global prevalence of 586,000 cases of thyroid cancer, thyroid cancer is the 10th most common malignancy. Despite advancements in early detection and treatment, the incidence of thyroid cancer continues to increase in the United States. This study aims to assess disparities in mortality trends stratified by age, sex, race, geography, urbanization status, and location of death, to guide clinical decision making. Methodology: Mortality data on thyroid cancer were extracted from the CDC-WONDER database, from 1999 to 2020. Age-adjusted mortality rates (AAMRs) and crude mortality rates (CMRs) per 100,000 were stratified by age, sex, race, geography, urbanization status, and place of death. Joinpoint regression software was used to determine annual percent change (APC) and average APC. Results: From 1999 to 2020, a total of 46,777 deaths attributed to thyroid cancer occurred in the United States, among individuals aged ≥ 25 years. The overall AAMRs showed a positive trend, increasing from 0.6 per 100,000 (95% CI: 0.5-0.6) in 1999, to 0.7 (95% CI: 0.7 - 0.7) in 2020. 56.63% of those deaths, or 26,493 deaths, occurred in women. When stratified by age group, the 85+ age group had the highest CMR of 9 (95% CI: 8.3-9.7). The racial group with the highest AAMRs were Whites, with an AAMR of 0.7 per 100,000. Mortalities in the South region accounted for 33.5% of total deaths. Moreover, metro areas also had higher mortality rates than non-metro areas. Information regarding place of death was only available for 8242 deaths, with 2763 of them occurring in medical settings. Conclusion: Mortality rates in all population groups increased from 1999 to 2020, with variations in mortality rates noted among them. Risk stratification of high-risk groups, such as older people and women, and targeted interventions are key for addressing disparities in mortality rates. Presentation: Saturday, July 12, 2025
