Genomic CpG methylation and TKI-response of the patient with advanced stage lung adenocarcinoma


ABSTRACT: The DNA methylation signature involved 87 differentially methylated regions (DMR) that distinguished patients’ response to EGFR-TKIs. The methylation level of HOXB9 (cg13643585) which was negatively correlated with gene expression and annotated as function of transcription factor displayed 88% and 92% of sensitivity with respect to objective response rate (ORR, OR=9.25, p=0.0002) and disease control rate (DCR, OR=6.64, p=0.0009), respectively. Importantly, HOXB9 gained methylation in patients with progressive disease (PD) relative to partial response (PR) patients specific to those who harbored EGFR-activating mutations (ORR, OR=8.8, p=0.0045; DCR, OR=6.63, p=0.018).
