THE MOLECULAR AND CLINICAL INTERPLAY BETWEEN HELICOBACTER PYLORI INFECTION AND GASTRIC CARCINOGENESIS: A COMPREHENSIVE REVIEW

Abstract

Gastric cancer is a complex ailment characterized by numerous contributing factors, and it represents a
substantial contributor to mortality rates. The risk factors associated with this illness involve a
combination of environmental factors and factors that inuence the interaction between the host and pathogens. The
aforementioned elements exhibit complex interplay, hence augmenting the progression of stomach cancer. Gastric
adenocarcinomas can be classied into two separate forms: intestinal and diffuse. There exists a hypothesis suggesting a
potential causal relationship between the infection of Helicobacter pylori (H. pylori) and the development of chronic active
gastritis, which in turn could contribute to the subsequent creation of intestinal-type adenocarcinoma The activation of
oncogenic pathways by CagA and peptidoglycan, which are delivered into the gastric epithelial cells during H. pylori infection,
is considered a signicant contributing factor to tumor growth. The application of antibiotics in the eradication of H. pylori has
the potential to reduce the incidence of precancerous lesions. However, this impact is predominantly found in the early stages of
stomach carcinogenesis. The acquisition of this knowledge has the potential to signicantly augment the efcacy of
preventative strategies and therapeutic therapies for stomach cancer. The present review offers a complete examination of the
existing literature about gastric cancers, with specic emphasis on the inuence of Helicobacter pylori infection. The
advancement of cancer is aided by the interactions that take place between the immune system of the host and
microorganisms.
