Patient case: 65-year-old female with squamous cell lung cancer; genetic feature: FGFR1 amplification

Clinical trial: Apatinib Combine With EGFR-TKI for Advanced EGFR-TKI-resistant Non-Small Cell Lung Cancer

Summary: Epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs), including gefitinib 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. Apatinib is a highly selective VEGFR2 inhibitor and reduces the angiogenesis of tumor efficiently. In this study, the investigators aim to explore the efficacy and reasonable dosage of apatinib combining with EGFR-TKI in advanced non-squamous non-small cell lung cancer with EGFR-TKI resistance.

Detailed description: Primary Outcome Measure: efficacy and reasonable dosage of the combination of apatinib and EGFR-TKI in advanced non-squamous non-small cell lung cancer with EGFR-TKI resistance.
  Secondary Outcome Measures: Progression free survival, overall survival, Side effects.
