Feasibility Of Cancer Prevention Research Articles

Dietary, non-microbial intervention to prevent Helicobacter pylori-associated gastric diseases.

Since the discovery of Helicobacter pylori (H. pylori) infection as the major cause of gastroduodenal disorders including acute and chronic gastritis, gastroduodenal ulcer, chronic atrophic gastritis, and gastric cancer almost three decades ago, the possibility of preventing these clinical diseases through eradicating H. pylori has been the focus of active research, but soon debate in the scientific community, though eradication opens the feasibility of cancer prevention and the removal of bacteria significantly prevents development or recurrence of peptic ulcer diseases and some clinical diseases, was proposed due to uncertainty in either achievement of complete eradication or inefficacy in cancer prevention with eradication alone. Still its linkage to gastric cancer is incontestable. Since the multiple combination of bacterial factors, environmental insults, and the host immune response that drives the initiation and progression of mucosal atrophy, metaplasia, and dysplasia toward gastric cancer is intervened, simple eradication deemed the feasibility of cancer prevention. Therefore, our group open strong hypothesis that non-microbial, dietary approach might be the alternate, for which several interventions of nutritional components can highlight rejuvenation of chronic atrophic gastritis as well as amelioration of H. pylori-associated procarcinogenic inflammation. In this review article, the experience and outcome regarding nutritional application to rejuvenate gastric atrophy will be introduced, using Korean red ginseng, garlic extracts, cancer preventive Korea kimchi, n-3 polyunsaturated fatty acids (PUFA), special form of licorice, and probiotics. The detailed influence of dietary intervention and bacterial eradication therapy on disease progression and reversibility of premalignant lesions are discussed.
