Clinical Factors Affecting the Response to Osimertinib in Non-Small Cell Lung Cancer Patients with An Acquired Epidermal Growth Factor Receptor T790M Mutation: A Long-Term Survival Analysis

ConclusionsThis is the first reported survival analysis of osimertinib-treated Chinese patients, which indicates a median OS of 47.86  months. The EGFR T790M mutation is likely to coexist with 19del and indicate longer PFS and OS1 than EGFR 21 L858R/T790M. Additionally, the extrathoracic metastasis status and biopsy specimen type might also affect the survival of patients treated with osimertinib.
