Introduction: The epidermal growth factor receptor (EGFR) is mutated in 15% of adenocarcinomas of the lung. In addition, the anaplastic lymphoma kinase (ALK) is altered in 8% of adenocarcinomas of the lung. Treatment of EGFR mutant and ALK translocation-positive tumors in NSCLC with tyrosine kinase inhibitors (TKI) results in a dramatic therapeutic response and has revolutionized therapy. Unfortunately, resistance to TKIs invariably develops. Many promising new therapies are under investigation to overcome the resistance. Areas covered: We analyzed the current primary literature and recent national meetings to evaluate the clinical characteristics and therapeutic implications of relevant treatments for EGFR mutant and ALK-positive NSCLC in the first-line, acquired resistance, and adjuvant settings. Expert opinion: Treatment with EGFR TKIs in the first-line setting of EGFR mutant NSCLC results in a significant clinical benefit. Several promising third generation EGFR TKIs are being evaluated in Phase II and III trials in the acquired resistance setting. Crizotinib is superior to chemotherapy in the first-line setting for ALK-positive NSCLC. Ceritinib is effective and approved for ALK-positive NSCLC in the acquired resistance setting. Continued investigation is needed to develop novel therapies to overcome acquired resistance to TKIs.
