Lung cancer is the malignant tumor with the highest mortality, of which non-small cell lung cancer (NSCLC) is the most common type. Studies have confirmed that mutations of epidermal growth factor receptor (EGFR) are closely related to the development of non-small cell lung cancer. Related drugs targeting EGFR common mutations, such as deletion of exon 19, insertion of exon 20 and point mutation of exon 21, have been applied in clinical practice. However, mutations in the extracellular domain of EGFR were found in some patients with NSCLC. This rare mutation also affects the treatment of these patients. This review introduces the research progress of EGFR extracellular region mutations in non-small cell lung cancer, and explores effective treatments for such mutations, with the hope of providing a reference for the diagnosis and treatment of lung cancer patients with EGFR extracellular region mutations.
