COPD was associated with higher lung-cancer incidence and mortality
A review of United States observational studies found higher lung-cancer odds and mortality hazards among adults with COPD, with mixed subgroup findings.
Based on the published abstract. The full paper may contain additional methods, results and limitations.
The 30-second takeaway
Adults with chronic obstructive pulmonary disease had higher odds of developing lung cancer and higher hazards of dying from it than adults without COPD. These are observational associations, not proof that COPD caused either outcome. Subgroup findings were mixed, so the overall pattern should not be treated as identical across smoking histories or demographic groups.
This abstract-based account lacks follow-up durations and details of adjustment for smoking or other factors. The abstract also leaves the intervals around its estimates unlabeled.
What researchers found
Developing lung cancer
COPD versus no COPD in US adults; this compares odds, not probabilities. Follow-up duration and interval type were not specified.
Separate cancer outcomes
The review separately examined new lung-cancer diagnoses and lung-cancer deaths. Odds ratios describe the former association; hazard ratios describe the latter. Neither measure gives the absolute number of additional people affected.
Reading the subgroup findings
Analyses using self-reported COPD or breathing tests found higher lung-cancer incidence; an increased mortality association was not demonstrated. This does not rule out such an association or establish that results differ by assessment method.
