A Prospective Study for the Early Diagnosis of Lung Cancer in Korean Females Who Are Never Smoker with a Family History of Lung Cancer

Interested individuals will contact a research coordinator who will help to assess for study eligibility. Individuals who are eligible and able to sign informed consent will then proceed to have a LDCT screening exam with a result reported by a radiologist approved to read lung cancer screening scans. Results of this screening test will be discussed with the subject and further recommendations will be given. Negative results will proceed to have repeat LDCT exams for two additional years. Positive results will be recommended to have further diagnostic work-up, and possible treatment. Those with positive findings may be recommended to repeat a LDCT at varied intervals (e.g. at 3 months, at 6 months, etc.) per Lung-RADS recommendations which can be conducted as a research LDCT or as standard-of-care.

In addition, blood draw collection for a plasma-based assay will be collected at baseline, first year and second year for all patients along with the repeated LDCT scans.

A medical history questionnaire containing questions regarding ethnicity, family history of lung cancer, environmental exposures including secondhand smoke exposure, and a residential district to estimate the exposure of PM2.5 or PM10 will be given to the patient at the initial visit after informed consent has been obtained (Appendix A). Questionnaire can be collected within 1 month from the baseline consent.
