Preliminary Study of Pancreatic Cancer Associated with Helicobacter pylori Infection

Little is known about the relationship about Helicobacter pylori (H. pylori) infection and pancreatic, and this study was set to investigate how H. pylori infection is correlated with pancreatic cancer and provide references for the clinical prevention and treatment of pancreatic cancer. 56 cases of pancreatic cancer patients admitted to the hospital from August 2012 to August 2013 were collected as the observation group. The anti-Hp IgG (H. pylori-specific antibodies), Hp IgM (H. pylori antibodies), and CagA-Hp-IgG (H. pylori serotoxin-associated protein a antibody) in the serum were measured and compared with the related indicators of control group (60 cases of healthy subjects). The H. pylori infection rate was 64.29 % in the observation group, and that in the control group was 46.67 %. Our results showed that the H. pylori infection rate in the observation group was significantly higher than that in the control group, which was statistically different (P < 0.01). The positive rate of CagA-Hp in the observation group was 38.88, and 21.53 % in the control group, for which the observation group was significantly higher than the control group (P < 0.05). The occurrence of H. pylori infection in patients with pancreatic cancer was also positively correlated with the smoking history and the history of chronic pancreatitis (P < 0.05). Helicobacter pylori infection is one of the risk factors for pancreatic cancer, and the patients with positive CagA-Hp have the higher risk, so the prevention and treatment of H. pylori infection would be beneficial for the prevention and treatment of pancreatic cancer.
