Global Patterns of Incidence and Mortality in Lung Cancer

Abstract

Objectives: Lung cancer has been the leading cause of cancer mortality, and its incidence is growing throughout the world. This study aims to compare the distribution of the six World Health Organization by configural frequency analysis (CFA). Methods: The National data (GLOBOCAN 2012) were included in the analysis. Data were analyzed by CFA which is used for the analysis of multiway contingency tables. Results: In Africa, East Mediterranean, Europe, and Southeast Asia, lung cancer incident cases were observed to be higher than expected. Under the years <70, in Africa, East Mediterranean, Europe, and Southeast Asia, lung cancer mortality is significantly underrepresented and therefore antitypes. Here, lung cancer mortality was observed lower than expected. In the more developed regions, lung cancer incident cases and mortality were significantly overrepresented in almost all age groups in both male (years <55) and female, but in the less developed regions, it was significantly underrepresented in almost all age groups. Conclusion: The majority of the global lung cancer burden occurred in the more developed countries. If the current situation remains unchanged, incidence and mortality may continue to increase.
