compare apatinib plus chemotherapy drug versus chemotherapy drug as second-line treatment in nsclc

Conditions: Nonsmall Cell Lung Cancer

Summary: apatinib, a novel targeted inhibitor of vegf receptor 2 (vegfr2), shows significant antitumor activity in the patients with gc. the purpose of this study is to determine whether apatinib plus chemotherapy drug can improve progression free survival compared with chemotherapy drug in patients with metastatic the non-small cell lung cancer who failed one lines of chemotherapy.

lung cancer is the leading cause of cancer death in world wild, especially non-small cell lung cancer (nsclc). detection and early intervention are difficult because pathogenesis of nsclc is not yet entirely clear.most of them are advanced or metastatic patients, so approach 3/4 nsclc undergo chemotherapy. fewer treatment options exist on nsclc whom is wild type of egfr. the patient did not benefit from the existing treatment regimen after first-line treatment. there is currently no effective drug to treat this group of patients. apatinib, a novel targeted inhibitor of vegf receptor 2 (vegfr2), shows significant antitumor activity in the patients with gc. the purpose of this study is to determine whether apatinib plus chemotherapy drug can improve progression free survival compared with chemotherapy drug in patients with metastatic the non-small cell lung cancer who failed one lines of chemotherapy.
