Research status and development of digestive system microecology and pancreatic cancer / 中华消化外科杂志

ABSTRACT

Pancreatic cancer is a highly malignant tumor of the digestive system, also known as "the king of cancer" . Its incidence is increasing year by year worldwide. At present, there is still a lack of effective screening methods for pancreatic cancer, and the early symptoms are not obvious. Most pancreatic cancer is diagnosed in the late stage, and the best time for surgery has been lost, and patients often have poor response to radiotherapy, chemotherapy and targeted therapy, so the prognosis is very poor. The occurrence and development of pancreatic cancer are closely related to genetic background, environmental factors, basic diseases and living habits. So far, although certain risk factors have been identified, such as smoking, obesity, alcohol, chronic pancreatitis, type 2 diabetes mellitus, and family history, the cause of pancreatic cancer is still not very clear. In recent years, more and more studies have shown that in addition to the already recognized risk factors for pancreatic cancer, there is a certain relationship between digestive microecological disorders and the progression of pancreatic cancer. The authors review the research status of digestive system microecology and pancreatic cancer, in order to understand the role of digestive system microecology disorders in the occurrence and development of pancreatic cancer, thus providing a new way to effectively improve the prognosis of pancreatic cancer.
