Prognostic significance of longitudinal evaluation on egfr mutant ctdna during tki treatment in nsclc

Abstract

Detection of EGFR mutations in tumor tissue is the gold standard for prescribing tyrosine kinase inhibitor therapy.However even in the same molecularly defined population effect of the treatment, response duration and survival might differ significantly. We did a prospective clinical trial to assess ctDNA-based EGFR mutations as a prognostic marker for patients with lung adenocarcinoma receiving TKI as first-line treatment.
