LOTUS Patient Population

2014-2019 (Estimated) Aggregate Characteristics

Sex

Lung cancer screening may have different effects in men and women; our consortium is well-suited to evaluate these potential differences.

RACE AND ETHNICITY

Lung cancer incidence and mortality are higher in groups that are often medically underserved, including Non-Hispanic Black populations. Thus, it is important that lung cancer screening reach diverse populations, so that lung cancer related health disparities are reduced and not worsened through lung cancer screening programs.

The LOTUS consortium covers a diverse population, so that we can study lung cancer screening uptake and impacts in different groups and identify ways to optimize lung cancer screening to benefit diverse populations.

AGE

Increasing age is a risk factor for lung cancer, and current guidelines use age as one of the criteria for who should receive lung cancer screening. Understanding the benefits and risks of lung cancer screening at different ages is important so that policy-makers, patients, and doctors can make informed decisions about who should initiate lung cancer screening.
