Abstract

Abstract:

Pancreatic cancer (PC) is a highly malignant digestive system tumor with a poor survival rate and prognosis. Most patients with pancreatic cancer have no obvious clinical manifestations in the early stage of the disease, and are found to be in the middle and late stage of the disease when they seek treatment.A unique and complex tumor microenvironment (TME) is formed during its development and evolution. Due to the occult nature of pancreatic cancer, for patients with advanced pancreatic cancer, some traditional treatment methods such as surgical resection and chemotherapy are very limited, and there is a lack of effective treatment programs. Of course, this is also related to the immunosuppression of the TME of pancreatic cancer. Some immunosuppressive cells, such as myeloid-derived suppressor cells (MDSCs) and regulatory T cells (Tregs), play an important immunosuppressive role in helping tumor immune escape. Therefore, it is considered to be a major difficulty in the treatment of pancreatic cancer. In recent years, with the in-depth study of TME, immunotherapy has gradually become a new therapeutic strategy, and has made great progress in the treatment of various malignant tumors. The study found that targeted MDSCs therapy is a new and effective treatment for pancreatic cancer.In this paper, we introduce the role of MDSCs in TME and their progress as potential targets for immunotherapy of pancreatic cancer, hoping to provide new directions for the treatment of pancreatic cancer and other tumors.

Key words: myeloid-derived suppressor cell (MDSC), pancreatic cancer, immunosuppression, targeted therapy
