Lung cancer is the most common cancer worldwide, non-small cell lung cancer (NSCLC) comprises about 85% of all lung cancer cases, which is the leading cause of cancer mortality, and adenocarcinoma is the most prevalent subtype. Gefitinib showed lower efficiency of treatment as second or third-line in patients with advanced adenocarcinoma NSCLC. It is necessary to further improve the efficiency of treatment in patients with advanced NSCLC. Immunotherapy with cytokine-induced killer cells (CIK) may improve tumor control and survival, as well as a better quality of life. This study is to evaluate the efficacy of Autologous CIK Transfusion plus Gefitinib for advanced, recurrence, metastatic adenocarcinoma NSCLC.
