About

Epidermal Growth Factor Receptor tyrosine-kinase inhibitors （EGFR-TKIs）, including gefitinib，erlotinib and icotinib demonstrate excellent effect on the treatment of non small cell lung cancer (NSCLC) patients with EGFR mutations. However, patients who are initially sensitive to the drugs eventually become resistance. In this study, the investigators aim to explore the efficacy of beta-elemene, combining with EGFR-TKI in advanced non-small cell lung cancer with EGFR-TKI resistance.

Full description

Epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs), including gefitinib，erlotinib and icotinib demonstrate excellent effect on the treatment of non-small cell lung cancer (NSCLC) patients with EGFR mutations. However, patients who are initially sensitive to the drugs eventually become resistance. Beta-elemene, a natural plant drug extracted from Curcuma wenyujin, has been used as an antitumor drug for different tumors, including NSCLC via mechanism that inhibits Ras/Mapk signaling and cell cycle progression.In this study, the investigators aim to explore the efficacy of beta-elemene, combining with EGFR-TKI in advanced non-small cell lung cancer with EGFR-TKI resistance.
