The identification of Epidermal Growth Factor Receptor (EGFR) mutations represents a major milestone in the treatment of advanced non-small-cell lung cancer. The activating mutations of EGFR occur in 10%-15% NSCLC Caucasian and 30%-40% East Asian patients, approximately. The EGFR T790M mutation is present in approximately 50%-60% of resistant cases as a secondary mutation, but as a primary less than 1%. Treatment with thyrosine kinase inhibitors (TKIs) is more efficient with fewer side effects compared with classic treatment modalities. We reported a rare case lung adenocarcinoma patient with primary T790M mutation treated with gefitinib as a fist line and osimertinib as a second line therapy.
