EP01.01. Median Age at Lung Cancer Diagnosis in 60 Countries: An International Comparative Study - PDF(Slides)

Pdf Summary

This study examines the median age at diagnosis of lung cancer across 60 different countries. The researchers found that there were significant differences in the median ages at diagnosis after accounting for differences in the population age distribution. These differences could be attributed to variations in exposure to risk factors such as tobacco use and outdoor air pollution. The study suggests that these differences may reflect differences in disease biology and epidemiology across populations, and can help identify settings that would benefit from earlier interventions for prevention, such as screening programs. The researchers used a standard population estimate to calculate adjusted median ages at diagnosis in each country. The study also mentions that patterns may change in the future with the implementation of lung cancer screening programs, potentially shifting median ages towards the ages eligible for screening in each country. The study found that after adjustment, there was an increase in estimated median ages at diagnosis in low- and middle-income countries, while there was a decrease in high-income countries. The youngest ages at lung cancer diagnosis were observed in Bulgaria, France, and Algeria, while the oldest ages were observed in Kuwait, Peru, and Bahrain. Overall, this study provides valuable insights into the international variations in median age at lung cancer diagnosis and the potential factors contributing to these differences.
