Circulating tumor DNA to investigate resistance mechanism and clone evolution of ALK TKI treated lung adenocarcinoma.

Genotyping of sequential post-progression plasma specimens reveals that treatment with sequential first-, second-, and third-generation ALK inhibitors can accelerate the accumulation of ALK resistance mutations and may lead to treatment-refractory compound ALK mutations. The selection for optimal first-line TKI is very important to achieve a more efficacious long-term strategy and prevent the emergence of on-target resistance. READ ARTICLE
