and Gastric Cancer: Pathogenetic Mechanisms.

Gastric cancer is the sixth most commonly diagnosed cancer and the fourth leading cause of cancer death worldwide. () is one of the main risk factors for this type of neoplasia. Carcinogenetic mechanisms associated with are based, on the one hand, on the onset of chronic inflammation and, on the other hand, on bacterial-specific virulence factors that can damage the DNA of gastric epithelial cells and promote genomic instability. Here, we review and discuss the major pathogenetic mechanisms by which infection contributes to the onset and development of gastric cancer.
