Population data reveals lung cancer burden discrepancies in China, suggesting improved registration methods for accuracy.
Disparities in incidence and mortality vary with the direction and magnitude of interprovincial migration, indicating that household-registered residency-based registration overestimates lung cancer burden in high-immigration regions and underestimates it in high-emigration regions. We recommend transitioning to resident population-based registration to improve the accuracy of lung cancer burden estimates of cancer surveillance, particularly in regions with substantial migrant populations.
