    Longitudinal monitoring by next-generation sequencing of plasma cell-free DNA in ALK rearranged NSCLC patients treated with ALK tyrosine kinase inhibitors. (PubMed, Cancer Med)
    cfDNA-NGS facilitates detection of ALK fusions and resistance mutations, assessment of prognosis, and monitoring dynamic changes of genomic alterations in ALK+ NSCLC treated with ALK-TKI.

    [VIRTUAL] Clinical utility of ctDNA for detection of EGFR, ALK, BRAFV600E alterations and resistance mutations in patients with NSCLC at failure to targeted therapy (ESMO 2021)
    In samples from EGFRm ex19/21 pts treated with 1st/2nd generation (gen.) TKI (n=51), the T790M mutation was detected in 27%; in those from pts treated with osimertinib (n=15), the C797S rate was 13%. In ALKr pts treated with crizotinib (n=17), ≥1 ALK resistance mutations were found in 12% (1 G1269A+F1174L, 1 G1202R), after 2nd gen. (n=16) in 31% (3 G1202R, 1 D1203N+F1174C, 1 T1151R) and after lorlatinib (n=16) in 13% (2 G1202R)... ctDNA is feasible in pts with NSCLC harbouring EGFRm, ALKr, BRAFV600Em for detecting driver and resistance GAs at PD, providing clinical informative for treatment selection at TKI failure in 22% of cases. Outcomes of the following therapies based on ctDNA will be presented at the congress.
