Global incidence and mortality trends of corpus uteri cancer and associations with gross domestic product, human development index, lifestyle, and metabolic risk factors

Objective: To evaluate the worldwide distribution, risk factors, and temporal trends of corpus uteri cancer for different countries and age groups. Method: Data relating to corpus uteri cancer in 2020 were retrieved from the Global Cancer Observatory database. Data from Cancer Incidence in Five Continents and the WHO mortality database were used for trend analysis. Age-standardized rates (ASR, per 100 000 persons) were calculated for incidence and mortality. Joinpoint regression analysis was used to estimate the 10-year annual average percent change (AAPC). Results: A total of 417 367 new cases and 97 370 new deaths of corpus uteri cancer were reported globally in 2020. The highest incidence was observed in high-income countries. Higher ASR of mortality of corpus uteri cancer was associated with a higher gross domestic product per capita, higher Human Development Index, and higher prevalence of smoking, alcohol drinking, physical inactivity, obesity, hypertension, diabetes, and lipid disorders. There was a substantial increasing trend of corpus uteri cancer, with the largest AAPC in incidence found in Japan, followed by India, Chile, Korea, and Thailand. Conclusion: The incidence and mortality of corpus uteri cancer have been increasing substantially for the past 10 years. Intensive lifestyle modifications are needed, especially among younger women.
