Abstract Purpose There are complex and paradoxical patterns in lung cancer incidence by race/ethnicity gender; compared to non-Hispanic White (NHW) males, Black (NHB) males smoke fewer cigarettes per day less frequently but have higher rates. Similarly, NHB females likely comparable rates NHW females. We use a multistage carcinogenesis model study the impact of smoking on individuals Multiethnic Cohort Study (MEC). Methods The effects tumor initiation, promotion, malignant conversion, versus adults MEC were analyzed using Two-Stage Clonal Expansion (TSCE) model. Maximum likelihood methods used estimate parameters assess differences race/ethnicity, gender, history. Results Smoking increased promotion conversion did not affect initiation. Non-smoking-related smoking-related differed gender. initiation than individuals, whereas was lower individuals. Conclusion Findings suggest that while plays an important role risk, background risk dependent also significant under-recognized explaining differences. Ultimately, resulting TSCE will inform race/ethnicity-specific natural history models preventive interventions US outcomes disparities race/ethnicity.
