At present, the most important treatment methods for tumor are surgery, radiotherapy, chemotherapy and targeted therapy, but these treatment methods have different limitations, the overall treatment effect is poor, and the long-term survival rate of patients is low.

Neoantigens are specific antigens produced by genetic mutations in cancer cells that activate T cells to produce an immune response, thereby inhibiting tumor growth. Because T cells that can recognize neoantigens in the body are relatively rare, and tumor cells escape the killing of specific T cells through immune escape mechanism, people can synthesize these mutated peptides through synthetic technology in vitro, and then inject them into patients to stimulate a large number of T cells that can recognize these neoantigens in the body. Thus, the purpose of specifically killing tumor cells carrying such neoantigens is achieved, and the occurrence of side effects is avoided.
