Global, regional, and national burden and trends analysis of malignant neoplasm of bone and articular cartilage from 1990 to 2021: A systematic analysis for the Global Burden of Disease Study 2021

Background

Malignant neoplasm of bone and articular cartilage (MNBAC) is one of the causes of cancer-related deaths worldwide. To date, there is a lack of detailed studies on the disease burden of MNBAC.

Methods

Data on the incidence, mortality, and disability-adjusted life years (DALYs) of MNBAC from 1990 to 2021 were obtained from the Global Burden of Disease study. We estimated the trends in the burden of MNBAC by calculating the estimated annual percentage change (EAPC) in age-standardized rates by region, country, and social development index.

Results

Globally, the cases of incidence and deaths of MNBAC showed a significant upward trend. In 2021, the global incidence cases of MNBAC were 91,375.1 (73,780.4–102,469.7), and the number of deaths was 66,114.3 (53,305.4–74,466.9). The age-standardized incidence, mortality, and DALYs rates were all on the rise, with EAPCs of 0.59 (0.51 to 0.68), 0.11 (0.02 to 0.21), and 0.08 (0 to 0.17), respectively. In 2021, China had the highest number of incidence cases and deaths. Two peaks in incidence cases and deaths were observed in the 15–19 and 65–69 age groups, with incidence rates and death rates generally increasing with age, and higher in males than females. The region with the highest incidence cases, deaths, and age-standardized incidence rate was East Asia, while Eastern Sub-Saharan Africa had the highest age-standardized mortality, and DALYs rates.

Conclusion

From 1990 to 2021, the global burden of MNBAC has continued to increase, particularly in East Asia, which faces the highest number of incidence cases and deaths, while Eastern Sub-Saharan Africa faces the highest ASMR and ASDR. To mitigate this burden, different regions should develop cancer control actions based on their respective epidemiological characteristics, with a focus on the elderly and adolescents, and control of risk factors.
