The idea of utilizing the human immune system to eradicate tumors has been successfully practiced for the past decades, as reported in multiple published studies. Among cancer types, non-small cell lung cancer (NSCLC) is considered the most lethal type, leading to the necessity of finding an effective treatment for this category of cancer. Building on the success of basic and preclinical studies, numerous clinical trials of cytokine-induced killer (CIK) cells or chimera antigen receptor (CAR) T cells for NSCLC therapy have been reported. In this review paper, we will summarize those findings in the context of clinical outcomes and adverse effects. In NSCLC, compared to CAR-T cells, CIK cells show relatively stronger antitumor efficacy and lower adverse effects. More clinical studies are needed to further confirm the clinical efficiency of both types of cellular immunotherapy.
