Recent advances and challenges of cellular immunotherapies in lung cancer treatment

Le résumé fourni par la source

Lung cancer is a major malignant tumor with high morbidity and fatality rates. For many years, traditional treatments for lung cancer have struggled to achieve a favorable outlook and prognosis. It is crucial to identify and innovate novel clinical therapeutic strategies and techniques to prevent tumor progression and prolong the survival time of patients with lung cancer. Cellular immunotherapies have revolutionized the treatment of malignant tumors and have been gradually applied in clinical practice. CAR-T therapy is the best-known cellular therapy and has achieved remarkable clinical outcomes in patients with hematological malignancies, but its effect on patients with lung cancer and other solid tumors is not satisfactory, partly because of the heterogeneity and complexity of lung cancers and the sterile TMEs. To further improve the clinical effect, multiple approaches and strategies have been adopted, including discovering new tumor antigen targets, improving safety, enhancing cytotoxicity, and increasing durability. Moreover, other cell-based immunotherapies have also showed great potential for the treatment of lung cancer, including TCR-T cells, TILs, CIK cells, NK cells, macrophages, and dendritic cells, which enriched the number of treatment choices for patients with lung cancer. In summary, the present article summarizes and highlights recent advances and challenges in the use of cellular immunotherapies for the treatment of lung cancer, which might stimulate new ideas for the further development of cellular immunotherapies.
