About

Apatinib is a novel drug which was produced by Jiangsu Hengrui Medicine Co.Ltd in China. It is approved in advanced gastric cancer（GC）. The investigators just want to design such kind of trail to prove its effect when combined with S-1 as maintenance in advanced HER-2 negatived GC treated with 4 cycles chemotherapy and valued as SD. Investigators will evaluate progression free survival (PFS) and overall survival (OS).

Full description

GC is the second most common cause of cancer-related deaths worldwide. Most patients are diagnosed with unresectable advanced or metastatic stage disease losing the radical surgery opportunity. Till now there is no novel targeted drug which can increase the OS for advanced GC patients except HER-2 positive patients.

Approximate 30 patients with unresectable GC treated with 4 cycles chemotherapy and valued as stable disease will be enrolled in this study,The investigators will evaluate the efficacy and security of apatinib and S-1 as maintenance therapy.
