Projections of cancer mortality by 2025 in central China: A modeling study of global burden of disease 2019

Background: In China, there are few studies that have reported future estimations for cancer mortality. Therefore, this study aimed to assess cancer mortality in China and identify priorities for future cancer control strategies.Methods: Based on the Global Burden of Disease 2019 study, we extracted data on cancer-related deaths from 1990 to 2019 in Hunan Province, China. Under the current trends evaluated using a joinpoint regression model, we fitted a linear regression model for cancer mortality projections by 2025.Results: The age-standardized mortality rate of total cancer in Hunan, China, declined slowly and is projected to be 140.80 (95% confidence interval [CI]: 140.12-141.48) by 2025, with the mortality rate in men approximately twice that in women. In 2025, the top five causes of cancer -related deaths in males are projected to be lung, liver, colorectal, stomach, and esophageal cancers, with the corresponding causes in females being lung, breast, colorectal, liver, and cer-vical cancers. Between 2019 and 2025, male mortality rates due to liver and pancreatic cancer are expected to increase, while those due to the six leading female cancers will increase. Excess male deaths were associated with liver and esophageal cancers, while all main cancers in females will have excess mortality, except for colorectal cancer. Conclusion: A comprehensive cancer spectrum characteristic of both developing and developed countries will remain in Hunan, China. Lung cancer remains the most common cause of cancer -related deaths, and tobacco control efforts are urgently required. Additional efforts should be made to promote universal screening, improve access to cancer healthcare services, optimize medical payment models, and enhance access to valuable anticancer drugs.

Automated summary

This study aimed to assess cancer mortality in China and identify priorities for future cancer control strategies. The findings show that the age-standardized mortality rate of total cancer in Hunan, China, declined slowly and is projected to be 140.80 by 2025, with male mortality rate being approximately twice that of females. The top five causes of cancer-related deaths in males and females are projected to be lung, liver, colorectal, stomach, esophageal, and breast, colorectal, liver, and cervical cancers respectively. Lung cancer remains the most common cause of cancer-related deaths in Hunan, and efforts for tobacco control are urgently required.
