Small cell lung cancer is a very aggressive cancer, often accompanied by distant metastases, with a poor prognosis. 5-year survival rate of less than 5%, untreated patients with an average survival of only 2-4 months. The investigators consider to add apatinib,a tyrosine kinase inhibitor of VEGF,to the therapy of these patients. The investigators designed the study to explore the possibility of apatinib Plus Etoposide Capsule as the Therapy of Advanced Small Cell Lung Cancer.
The purpose of this study is to confirm the safety and efficacy of Apatinib Plus Etoposide Capsule as the Therapy of Advanced Small Cell Lung Cancer.
