Study of Early Cancer Biomarkers in Breath Condensate in Population of Individuals With High-Risk of Lung Cancer Undergoing LDCT Screening.

Summary

The trial will evaluate if the newly identified biomarkers of lung cancer in exhaled breath condensate are as a diagnostic tool comparable to the low-dose computer tomography (LDCT) implemented in lung cancer screening recently. Due to the possibility to collect breath condensate at any medical workplace and due to the relatively low financial cost of examination of the collected breath condensate could improve early diagnosis of lung cancer, differential diagnostics of lung nodules and thereby reduce both the unnecessary interventions and deaths from this type of cancer.
