Pilot Study of High Risk Lung Cancer Screening

A Prospective Pilot Study of Lung Cancer Screening in Patients at High Risk for Lung Cancer Who Do Not Meet Current Screening Guidelines

This study is a prospective trial of 200 individuals at high risk for lung cancer who are not eligible for lung cancer screening under current screening guidelines.

This study is a prospective trial of 200 individuals at high risk for lung cancer who are not eligible for lung cancer screening under current screening guidelines. Potential subject's 6 yr lung cancer risk must exceed 1.5% by the Tammamagi PLCO2012m calculator. Patients will undergo a non contrast CT chest for lung cancer screening. This cutoff should encompass in excess of 80% of all lung cancer cases (10). However, in patients 78-82 years old we will set the 6 yr lung cancer risk threshold at 4.0% as these patients will typically have other competing risks of death and this may potentially limit screening benefit in these older individuals.

Inclusion Criteria:

1. Adult 40-82 yrs of age.
2. Presenting for lung cancer screening evaluation.
3. Calculated 6 yr lung cancer risk >1.5% for patients 40-77 years of age or >4% for patients 78-82 years of age.
4. Able and willing to provide informed consent.

Exclusion Criteria:

1. Eligible for clinically indicated lung cancer screening (55-80 yr old, >30 pky smoking history, still smoking or quit smoking within the last 15 yr).
2. Chest CT performed within the last year.
3. Life expectancy less than 6 months.
4. Symptoms clinically consistent with lung cancer.
5. Unable or unwilling to undergo treatment for lung cancer.
6. Any individual who does not give oral and written consent for participation.
