Abstract

The invention discloses a universal polypeptide vaccine, which contains at least one of the following six mutations: KRAS-G12R, KRAS-G12V, CDKN2A-H83Y, KRAS-Q61H, TP53-R248W, CDKN2A-P94L. Specifically: at least one of the polypeptide sequences for the six mutations is included. The universal polypeptide vaccine can be used to prepare medicine for treating / preventing cancer (pancreatic cancer). The universal polypeptide vaccine of the invention has better immunotherapy effect on pancreatic cancer.

Description

technical field [0001] The invention relates to a universal polypeptide vaccine suitable for the treatment and prevention of pancreatic cancer. Background technique [0002] Pancreatic cancer (PAAD) is a highly malignant tumor of the digestive tract that is difficult to diagnose and treat. Its morbidity and mortality have increased significantly in recent years, and it is one of the malignant tumors with the worst prognosis. According to the latest statistics from the National Cancer Society in 2017, there were 53,670 new cases of pancreatic cancer in the United States, and 43,090 deaths. Compared with other malignant tumors, pancreatic cancer is the type of cancer with the closest new cases and death cases, which indirectly indicates the refractory nature of pancreatic cancer. On the other hand, the statistical report clearly pointed out that with the general improvement of tumor diagnosis and treatment in recent years, the survival rate of most malignant tumors has shown...
