Blood Versus Tissue Molecular Profiling for Cancer

“Achieving Value in Cancer Diagnostics: Blood Versus Tissue Molecular Profiling - a Prospective Canadian Study”
Current guidelines in non-small cell lung cancer recommend genomic assessment for mutations in EGFR and BRAF, gene rearrangements in ALK and ROS1, and resistance mutations such as T790M upon progression during EGFR inhibitor therapy. However, obtaining sufficient tumour tissue to test for these molecular alterations, as well as those with emerging targeted therapies, is challenging in lung cancer. A promising method to improve molecular diagnostic testing in lung and other cancers is the use of circulating cell-free DNA (cfDNA) obtained from blood samples or liquid biopsies. This multi-centre prospective study will compare blood-based profiling (using the GUARDANT360 assay) to standard of care tissue-based profiling within the Canadian system.
