Chimeric Antigen Receptor (CAR) T Cell Therapy for Digestive Tumor

Abstract

Digestive tumors commonly include esophageal cancer, gastric cancer, liver cancer, pancreatic cancer. Most of which are malignant tumors. All of the tumors do strong harm to human body and seriously affect the physical and mental health of patients. With the change of modern dietary habits, the morbidity of digestive tumors is increasing year by year, and the threat to the society is increasingly intensified. Traditional treatments for digestive tumors include surgical resection, chemotherapy and radiotherapy, all of which can alleviate the symptoms to some extent, but there are still many drawbacks. Compared with traditional therapy, immunotherapy has better therapeutic effect and fewer adverse reactions. Immunotherapy is to activate the human immune system and kill tumor cells by its own immune function. In immunotherapy, CAR-T cell therapy, a kind of personalized therapy that takes effect through gene modification to obtain T cells carrying tumor antigen-specific receptor, occupies a leading position. At present, CAR-T cells have shown excellent results in the treatment of lymphoid and hematopoietic tumors, on the contrast, there are few studies on the treatment of solid tumors. In this article, we summarized the application of some CAR-T cells in solid tumors of the digestive system.
