Nodule Solitary Pulmonary

This is a prospective observational study that will follow patients who undergo lung cancer screening at the San Francisco VA Medical Center, University of California, San Francisco (UCSF) Medical Center, and the San Francisco General Hospital. The proposed study will comprise of two primary populations to determine the ctDNA assay performance in a variety of clinical settings.

The goal of the NIMBLE study is to evaluate blood-based biomarkers for lung cancer risk prediction in patients referred with a lung nodule. Each blood biomarker will be evaluated for descriminating malignant from benign lung nodules alone and in combination with other blood biomarkers, patient characteristics and radiological features.
