Trends in lung cancer incidence in Spain (1990-2019): insights from Global Burden of Diseases data

This study examines lung cancer incidence in Spain (1990-2019) through age-period-cohort (A-P-C) analysis and Global Burden of Diseases (GBD) data, unravelling the complex interplay of age, period, and birth cohort in shaping these trends. Utilizing GBD and Spanish population data, the study calculates age-standardized incidence rates (ASIRs) and employs Joinpoint analysis to identify significant trends. A-P-C analysis dissects the individual effects of age, calendar period, and birth cohort on incidence patterns. Between 1990 and 2019, almost 738,000 cases of lung cancer were diagnosed in Spain, with an average annual increase of 1.7%. The ASIR of lung cancer in Spain from 1990 to 2019 showed a sustained upward trend in women (Average Annual Per cent Change: 2.5%, P
