The global burden of thyroid cancer and its attributable risk factor in 195 countries and territories: A systematic analysis for the Global Burden of Disease Study.

Abstract

BackgroundThyroid cancer is a growing threat to human health. Few studies have explored trends of thyroid cancer and relationships with social development factors. In this study, we explored the trend and relationship based on GBD.MethodsBy using GBD study, we obtained detailed data of thyroid cancer. Incidence, mortality and DALY were used to assess epidemiological characteristics. ASR and EAPC were used to estimate the trend.ResultsGlobally, the incidence significantly increased from 1990 to 2017, especially in high‐income regions. Males and middle SDI region demonstrated a higher increase of age‐standardized incidence rates. Unlike incidence trend, mortality trend showed a minor increase, and even showed a decreasing trend in some regions such as Eastern Sub‐Saharan Africa. Additionally, the DALY trend also demonstrated a slightly increase with an EAPC of 0.77 (95% CI 0.73–0.81). More significant increase of DALY was found in males, middle SDI region and high‐income Asia Pacific. The incidence of thyroid cancer peaked in middle‐aged people, while the mortality and DALY peaked in elder‐aged. Moreover, the proportion of thyroid cancer deaths contributable to high BMI was highest in developed countries and middle‐aged people.ConclusionsThyroid cancer is a public health problem worldwide. Over‐diagnosis might be partly responsible for its rising trend. It remains us to revise the guidelines to avoid unnecessary burdens. Moreover, we should pay attention to the risk factors of thyroid cancer. More targeted measures should be formulated to improve potential environmental and lifestyle‐related factors which might contribute to rising trend of thyroid cancer.
