111PCombined genomic and epigenomic assessment of cell-free circulating tumour DNA (cfDNA) for cancer diagnosis and recurrence-risk assessment in early-stage lung cancer

ConclusionUtilizing a plasma-only sequencing assay incorporating somatic genomic and epigenomic analysis, ctDNA detection rate in early stage lung cancer (stage I-III) can far outperform the detection rate of somatic sequence variant detection alone. And, the presence of pre-operative ctDNA in patients with early stage lung adenocarcinoma may identify those who are more likely to have disease recurrence.Legal entity responsible for the study: Guradant Health, Inc.FundingGuardant Health, Redwood City, CA, USA.DisclosureI.
