Detection of early-stage lung cancer in sputum using automated flow cytometry and machine learning

Respiratory Research, January 21, 2023   Authors Lemieux, M.E., Reveles, X.T., Rebeles, J. et al. Abstract Background Low-dose spiral computed tomography (LDCT) may not lead to a clear treatment path when small to intermediate-sized lung nodules are identified. We have combined flow cytometry and machine learning to develop a sputum-based test (CyPath Lung) that can assist physicians in decision-making in such cases. Methods Single cell suspensions prepared from induced sputum samples collected over three consecutive days were labeled with a viability dye to exclude dead cells, antibodies to distinguish cell types, and a porphyrin to label cancer-associated cells. The labeled cell suspension was run on a flow cytometer and the data collected. An analysis pipeline combining automated flow cytometry...

Learn More about CyPath® Lung

The CyPath® Lung Flow Cytometry Test has been licensed by Precision Pathology Services for commercial sale as a Laboratory Developed Test (LDT).

CyPath® Lung is a non-invasive test that assists clinical decision-making in lung cancer patients whose low-dose computed tomography (LDCT) has demonstrated a suspicious finding.

The test reveals the lung micro-environment by automated analysis of sputum using flow cytometry to characterize cell populations indicative of cancer in the lung.
