Translational study demonstrates successful ex-vivo expansion of circulating tumor cells in early-stage lung cancer, indicating potential for deep genomic profiling of metastatic drivers.

Key Points

To develop a microfluidic three-dimensional co-culture system capable of capturing and expanding rare circulating tumor cells from early-stage lung cancer patients for downstream genomic analysis.
Engineered an in-situ microfluidic 3D co-culture platform that mimics the tumor microenvironment to promote the growth of circulating tumor cells (CTCs).
Isolated and cultured CTCs from peripheral blood samples collected from 19 patients with early-stage lung cancer (N=19).
Performed targeted TP53 mutation analysis and next-generation sequencing to evaluate concordance between expanded CTCs and matched primary tumors.
Successfully expanded CTCs ex vivo in 14 of 19 early-stage lung cancer patients (73.7% success rate).
Identified matching TP53 mutations between expanded CTCs and primary tumors, with next-generation sequencing revealing shared mutations across additional cancer-associated genes.
