About 9.2%-45.8% of Chinese patients with Non-small cell lung cancer were positive for EGFR gene mutation. Gefitinib, Erlotinib, Icotinib, Afatinib showed efficacy superior to that of chemotherapy in the treatment of EGFR mutation positive advanced NSCLC, and lower rates of serious adverse events. However, after a median of 8 to 13 months of disease control, patients ultimately progress due to acquired resistance of EGFR-TKIs. Elemene, a chemotherapeutic isolated from the Chinese medicinal herb Rhizoma Zedoariae, has been shown to have a comprehensive anti-tumor effect and the potential effect on reversing drug resistance. The study is a real-world study and the case records of patients with advanced non-small cell lung cancer who visited the research centers from January 2014 to December 2017 and met the inclusion criteria will be collected. Medical data including patient demographic, tumor characteristics, laboratory examination, history of treatments, adverse reactions, and so on will be extracted to evaluate the synergistic effect and safety of Elemene plus TKIs in EGFR-mutated advanced non-small cell lung cancer.
