BackgroundGastric cancer is the fourth most frequently occurring malignancy after lung, breast, and colorectal cancer, and the second most common cause of death from cancer worldwide. Epidemiologic studies have examined the possible association between fish consumption and gastric cancer, but the results were inconclusive. We conducted a systematic review and meta-analysis to examine the association between fish intake and the risk of gastric cancer.MethodsPubMed was searched for studies published in English-language journals from 1991 through 2009. We identified 17 epidemiologic studies (15 case-control and 2 cohort studies) that included relative risks (RRs) or odds ratios (ORs) estimates with 95% confidence intervals (CIs) of the relationship between gastric cancer and fish consumption. Data were extracted using standardized data forms. Summary RRs or ORs for the highest versus non/lowest fish consumption levels were calculated using random-effects model. Heterogeneity among studies was examined using Q and I2 statistics.ResultsIn this study, 5,323 cases of gastric cancer and over 130,000 non-cases were included. The combined results from all studies indicated that the association between high fish consumption and reduced gastric cancer risk was not statistically insignificant (RR = 0.87, 95% CI = 0.71-1.07).ConclusionsCurrent evidence indicated that the association between fish consumption and risk of gastric cancer remains unclear.

“…A study conducted in Japan (17) reported data from 2 regions, one affected by atomic bomb and one not affected; only the results from the latter were considered in our analysis. Two studies reported the results separately using different groups of controls: population-and hospital-based controls (22), or including and excluding volunteers (35). In these instances, we only considered results in which population-based controls were considered and volunteers were excluded.…”

Background: Ecological and experimental studies have suggested an increased risk of gastric cancer in relation to consumption of pickled vegetables in East Asia.Methods: We conducted a meta-analysis of epidemiologic observational studies to evaluate the existing evidence. Searching PubMed, Vip Chinese Periodical, and China National Knowledge Infrastructure databases, we found a total of 60 studies, 50 case-control, and 10 prospective. We compared gastric cancer risk in pickled vegetable/food users versus nonusers (11 studies) or versus those in the lowest reported category of use (49 studies). Pooled results were computed with random-effects models.Results: Among case-control studies, 30 showed significant increased risk and one showed significant decreased risk. Among prospective studies, two showed a significant increased risk but none showed a significant decreased risk. The OR (95% CI) was 1.52 (1.37-1.68) for the overall association, 1.56 (1.39-1.75) for case-control, and 1.32 (1.10-1.59) for cohort studies. The OR (95% CI) was 1.89 (1.29-2.77) in Korean, 1.86 (1.61-2.15) in Chinese, and 1.16 (1.04-1.29) in Japanese studies, and 1.14 (0.96-1.35) in studies from other countries. There was high heterogeneity in overall and subgroup analyses. There was little evidence for publication bias.Conclusion: Our results suggest a potential 50% higher risk of gastric cancer associated with intake of pickled vegetables/foods and perhaps stronger associations in Korea and China.Impact: The results of this study may offer ways to reduce the risk of gastric cancer in highly populated areas with high incidence of gastric cancer.

Consumo alimentar e fatores dietéticos envolvidos no processo saúde e doença de Nikkeis: revisão sistemática

OBJETIVO: Analisar consumo alimentar e fatores dietéticos envolvidos no processo saúde e doença da população de nikkeis.MÉTODOS: Foi realizada revisão sistemática da literatura, com buscas nas bases de dados do Lilacs, SciELO e PubMed/Medline, referente ao período de 1997 a 2012, de estudos observacionais sobre o consumo alimentar de nikkeis. Inicialmente, foram analisados 137 títulos e resumos, sendo excluídos estudos de intervenção, aqueles que apresentavam somente níveis séricos de vitaminas e metabólitos e estudos que não contemplassem o objetivo da revisão. Desses, foram selecionados 38 estudos avaliados com base no método de Downs & Black (1998), adaptado para estudos observacionais, permanecendo 33 para análise.RESULTADOS: Foram encontrados poucos estudos sobre consumo alimentar de nikkeis fora do Havaí, dos Estados Unidos e do estado de São Paulo (principalmente em Bauru), no Brasil. Houve elevada contribuição dos lipídios no valor calórico total dos nipo-brasileiros, em detrimento dos carboidratos e das proteínas. Nos Estados Unidos, a prevalência de consumo de alimentos de alta densidade energética foi elevada em nipo-americanos. Os nisseis (filhos de imigrantes) apresentaram, em média, maior consumo de produtos da dieta japonesa, enquanto os sanseis (netos de imigrantes) apresentaram um perfil alimentar mais ocidentalizado.CONCLUSÕES: O consumo alimentar de nikkeis, embora ainda conservando alguns hábitos alimentares de japoneses nativos, revela alta prevalência de consumo de alimentos típicos do padrão ocidental (alimentos processados, ricos em gorduras e sódio e pobres em fibras), que pode estar contribuindo para o aumento de doenças crônicas nessa população.

Risk Factors for Stomach Cancer in Brazil (II): a Case-control Study among Japanese Brazilians in Sao Paulo

Abstract: The introduction of the habit of daily beef consumption among Japanese immigrants and their descendants may be associated with stomach cancer risk. The protective effect of fruit consumption was confirmed in this population.
