Several third-generation EGFR TKIs, such as osimertinib, have been explored and approved for conquering this resistance; however, acquired resistance to osimertinib is evident and the resistance mechanisms remain complex and incompletely explored %K NSCLC %K EGFR mutation %K tyrosine kinase inhibitor %K next-generation sequencing %U https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6302808/
