Serial liquid biopsies for detection of treatment failure and profiling of resistance mechanisms in KLC1–ALK-rearranged lung cancer

Genetic rearrangements involving the anaplastic lymphoma kinase (ALK) gene confer sensitivity to ALK tyrosine kinase inhibitors (TKIs) and superior outcome in non-small-cell lung cancer (NSCLC). However, clinical courses vary widely, and recent studies suggest that molecular profiling of ALK+ NSCLC can provide additional predictors of therapy response that could assist further individualization of patient management. In summary, our findings illustrate the utility of noninvasive longitudinal molecular profiling for assessing remission status, exploring mechanisms of treatment failure, predicting subsequent clinical course, and dissecting dynamics of drug-resistant clones in ALK+ lung cancer.
