The Study of Apatinib Plus CIK as the Third Line Therapy for Advanced Lung Adenocarcinoma Patients With Wild-Type EGFR

The Randomized, Controlled Clinical Trial of Apatinib Plus CIK as the Third Line Therapy for Lung Adenocarcinoma Patients With Wild-Type EGFR

The purpose of this study is to evaluate the safety and efficacy of Apatinib combined with cytokine-induced killer cell (CIK) vs Apatinib alone as the third line therapy for advanced lung adenocarcinoma patients with wild-type EGFR

400 patients with stage IIIB & IV lung adenocarcinoma who had received surgery and chemotherapy,will be randomly divided into group A（Apatinib plus CIK treatment ) or group B（Apatinib), and the randomize ratio will be 1:1. Patients in group A will receive 3 cycles of CIK treatment (every 1 year) and Apatinib (continuous).Patients in group B will receive only Apatinib (continuous) .

Inclusion Criteria:

• Histologically or cytologically confirmed Lung adenocarcinoma
• Wld-type EGFR
• Stage IIIB/IV
• Failure to prior chemotherapy
• Life expectancy of more than 3 months

• Age ≥ 18 years
• Performance status (WHO) < 3
• Adequate bone marrow function (absolute neutrophil count>1000/mm^3, platelet count > 100000/mm^3, hemoglobin > 9gr/mm^3)
• Adequate liver (bilirubin < 1.5 times upper limit of normal and SGOT/SGPT < 2 times upper limit of normal) and renal function (creatinine < 2mg/dl)
• Presence of two-dimensional measurable disease. The measurable disease should not have been irradiated
• Informed consent

Exclusion Criteria:
