Duodenogastric refluх: a look at the problem in terms of carcinogenesis

The role of duodenogastric reflux (DGR) in malignant degeneration of the gastric mucosa. It was demonstrated by immunohistochemistry using monoclonal antibodies to p53, PCNA, CD10, MUC2, MUC5AC, MUC6, CD31 and the polymerase chain reaction to detect CDX1, CDX2, FXR genes. The main carcinogenic components of bile are lysolecithin and conjugated bile acids. Biliary reflux increases the risk of malignant tumors in combination with Helicobacter pylori. DGR is one of the etiological factors for gastric cancer, so it determines the necessity for detailed diagnosis in clinical practice
