The Efficacy and Safety of Apatinib Combined With Etoposide in Heavily Pretreated Advanced Non-small Cell Lung Cancer

The Efficacy and Safety of Apatinib Combined With Etoposide in Advanced Non-small Cell Lung Cancer Patients Failed to Previous at Least 2rd Line Treatments

The development of anti-angiogenesis drugs has led to renewed enthusiasm in lung cancer treatments. Apatinib is a tyrosine kinase inhibitor which selectively inhibits the vascular endothelial growth factor receptor-2 (VEGFR-2). Etoposide is an oral preparation for lung cancer which is recommended by NCCN guideline. The investigators wondered whether these two drugs have synergistic effects when treating advanced non-small cell lung cancer patients who failed to previous at least 2nd line treatments. Thus, the aim of this trial is to investigate the efficacy and safety of apatinib combined with etoposide in heavily pretreated advanced non-small cell lung cancer.
