Retrospective cohort study characterizes lung cancer incidence in WTC-exposed individuals, suggesting unique risks persist beyond smoking history.

This study aims to characterize lung cancer incidence and risk factors in patients exposed to the World Trade Center disaster.
Retrospective chart review of 249 WTC-exposed patients at the Lung Cancer Evaluation Center.
Univariable comparisons made using Wilcoxon rank-sum and Fisher’s exact tests to analyze lung cancer diagnosis correlations.
Median follow-up period of 35.5 months from initial evaluation.
Lung cancer diagnosed in 9.2% of patients (23/249), at a median of 19.0 years post-exposure.
91% of patients had pulmonary nodules; significantly higher cancer incidence in former/current smokers (96%).
Increased prevalence of hypertension (74%) and diabetes (35%) in the cancer group, suggesting additional risk factors.

Albano et al. (2026) studied this question.
