Combination Diagnostics: Adding Blood-Based ctDNA Screening to Low-Dose CT Imaging for Early Detection of Lung Cancer

Cancer Discov. 2024 Nov 1;14(11):2025-2027. doi: 10.1158/2159-8290.CD-24-1195.

Abstract

Annual low-dose CT screening of individuals with a smoking history identifies early curable lung tumors and reduces cancer mortality by 20%, yet only a minority of eligible patients undergo such monitoring. Mazzone and colleagues apply a blood-based cfDNA fragmentomic assay as a high-sensitivity/low-specificity pre-screen to help stratify individuals who may benefit most from more definitive low-dose CT imaging. See related article by Mazzone et al., p. 2224.
