Abstract
AIM: We investigate the suitability of circulating tumor cells (CTCs) and circulating tumor DNA (ctDNA) in non-small-cell lung cancer management, which is challenging in conventional biopsies.
MATERIALS & METHODS: We performed serial blood extraction from 120 patients of varying EGFR status. Molecular profiling was performed using droplet digital PCR and correlated to survival outcome.
RESULTS: Overall, we observed 95% agreement using CTCs and ctDNA with conventional tissue biopsies, which indicated the disease's close correlation. The mutant signature was stable and captured the dynamic changes during treatment. It aided to stratify patients with worse survival outcome.
CONCLUSION: CTCs and ctDNA can complement current disease management. We demonstrated its effectiveness in continuous disease profiling, which is critical for clinical decision-making.
