Molecular Monitoring of cfDNA by ddPCR in Non-small Cell Lung Cancer Treated by Immunotherapy.

"Molecular monitoring by quantification of cell-free DNA (absolute value and variation from baseline) of two house-keeping genes (RPP30, TMEM11) by droplet digital PCR, during based-immunotherapy treatments of NSCLC patients.~Cell-free DNA will be extracted from 4 ml of plasma before treatments by immunotherapy, obtained from blood Streck® tubes.~Quantification of house-keeping genes (or mutated genes if some are previously routinely identified in tumor tissue) by ddPCR."
