TL;DR
This study analyzed thyroid cancer rates in China from 2005 to 2018, finding rising trends and regional clusters to guide prevention strategies.
Contribution
The study provides a detailed spatiotemporal analysis of thyroid cancer incidence in China using national registry data.
Findings
Thyroid cancer incidence in China increased by an average of 10.7% annually from 2005 to 2018.
Urban areas had higher incidence rates than rural areas, but the growth rate was slower in urban regions.
Northeastern China showed high-high clustering of thyroid cancer cases, indicating regional hotspots.
Abstract
The objective of this study was to analyze the incidence rate of thyroid cancer in China to elucidate its spatiotemporal distribution and to provide an evidence-based foundation for prevention and control strategies. Thyroid cancer incidence data from 2005 to 2018 were obtained from the China Cancer Registry Annual Reports (2008–2021). The Joinpoint regression model was used to describe the time trend, the age-period-cohort model was employed to analyze the effects of age, period and cohort on the thyroid cancer incidence, and spatial autocorrelation was used to analyze its spatial distribution. Results showed China's age-standardized incidence rate (ASIR) of thyroid cancer from 2005 to 2018 was 8.69 (95% CI: 8.55, 8.83) per 100,000, exhibiting an upward trend with an average annual percent change (AAPC) of 10.7% (95% CI: 9.5%, 11.9%). The ASIR was higher in urban than in rural areas,…
