Longitudinal monitoring by next generation sequencing of plasma cell-free DNA in ALK-rearranged non-small cell lung cancer (NSCLC) patients treated with ALK tyrosine kinase inhibitors

Background: Patients with anaplastic lymphoma kinase-rearranged (ALK+) NSCLC inevitably acquire resistance to ALK inhibitors. We hypothesized that longitudinal monitoring of cell-free plasma DNA (cfDNA) next generation sequencing (NGS) could predict the response and resistance of TKI therapy in ALK+NSCLC... Conclusions: NGS of cell-free plasma DNA is useful not only for the detection of ALK fusions and resistance mutations but also for assessing prognosis and monitoring the dynamic changes of genomic alterations in ALK+ NSCLC treated with ALK TKI.
