Joinpoint regression quantified temporal slopes; age\u2013period\u2013cohort (APC) and Bayesian APC (BAPC) models dissected historical drivers. Two complementary forecasting frameworks, BAPC (structural) and autoregressive integrated moving average (ARIMA; time-series) were used to generate burden trajectories to 2038.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Between 1990 and approximately 2020, the age-standardized disease burden generally declined, followed by a recent increase through 2023. Males consistently exhibit a higher disease burden than females; the 35\u201339-year age band showed the heaviest burden. Age-period-cohort analysis revealed divergent cohort effects: Cohort rate ratios generally declined across successive birth cohorts, with lower risks observed among cohorts born after 1985. For both sexes combined, BAPC point projections indicated that ASIR would increase from 1.53 to 2.54 per 100,000 and the age-standardized DALY rate from 64.71 to 79.77 per 100,000 between 2023 and 2038. These endpoint predictions corresponded to\n                      <jats:italic>post hoc<\/jats:italic>\n                      annualized geometric changes of\n                      <jats:bold>+<\/jats:bold>\n                      3.44% (UI\u202f\u2212\u202f9.37 to +7.83%) and +1.41% (UI\u202f\u2212\u202f7.86 to +5.31%), respectively. These estimates describe changes in age-standardized rates rather than absolute incident cases or DALY counts and are not BAPC drift coefficients. In contrast, ARIMA suggested modest declines or relatively flat trajectories for ASIR and ASMR, with wide prediction intervals. The discrepancy reflects model philosophy\u2014BAPC extrapolates age-period-cohort structures, whereas ARIMA extrapolates short-term autoregressive patterns.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>After decades of decline, lung cancer burden in Chinese adolescents and young adults is creeping upward and may accelerate.
