“…Estudos epidemiológicos têm demonstrado risco aumentado de até 6 vezes para o desenvolvimento de adenocarcinoma gástrico em indivíduos infectados pelo H. pylori (2,13,14,29) . O adenocarcinoma gástrico atinge altas taxas de incidência em países orientais como China e Japão, especialmente quando comparadas com as taxas encontradas no ocidente.…”

“…Evidence from epidemiological studies suggests a relative risk for subsequent development of gastric carcinoma of 3-6 in H. pyloriinfected persons (Nomura et al, 1991;Parsonnet et al, 1991;Eurogast Study Group, 1993). The impracticability of preventive treatment of all H. pylori-infected individuals implies an urgent need to identify patients who are at increased risk for the development of gastric carcinoma.…”

“…pylori-infected subjects have an increased risk of gastric cancer (Nomura et al, 1991;Parsonnet et al, 1991;Eurogast Study Group, 1993). However, only a few of them will actually develop gastric carcinoma later in life.…”

“…Furthermore, H. pylori may promote the formation of endogenous reactive nitrogen intermediates and induce free radicals as part of the host immune response, which may contribute to DNA damage and apoptosis [3]. H. pylori is able to colonize the human stomach mainly by the neutralization of its environment, by direct interaction with gastric ephithelial cells, and by the induction of several histological changes, including infiltration of the mucosa (chronic gastritis), loss of mucosal mass (ulcer, atrophy), and inflammation through infiltrating lymphocytes with the development of masses (hyperplastic polyps, adenomas, carcinomas and lymphomas) [4][5][6]. We previously showed that dietary antioxidative substances, including vitamin C and quercetin, can modulate the DNA-damaging effect of MNNG in human peripheral blood lymphocytes (PBLs); it was of interest to establish whether such modulation also occurs in gastric mucosa cells (GMCs) and whether it can be influenced by H. pylori infection [7].…”
