Feasibility of LCRT implementation (safety and
acceptance by subjects)
The LCRT biomarker requires a one-time acquisition of
NBEC through bronchial brush biopsy at the time of
bronchoscopy. In addition to the LCRT study, Department
of Defense Lung Cancer Research Program, and NIH recently
funded other large studies assessing utility of biomarkers
measured in NBEC obtained at bronchoscopy
intended to more accurately determine lung cancer risk
and/or to enable early lung cancer diagnosis (Massion,
Clinicaltrials.gov NCT01475500 CA152662 and CA102353;
