“…In 1956, Torgersen et al found that the prognosis for gastric cancer was related to the region of Oslo in which patients lived. Gastric cancer patients who lived in substandard housing areas had higher mortality rates [27] , [28] . Fifty-six years later, Siemerink et al used postal codes in The Netherlands to determine that neighborhood SES is an independent prognostic factor for gastric cancer survival [29] .…”

PurposeGastric cancer is a leading cause of death, particularly in the developing world. The literature reports individual socioeconomic status (SES) or neighborhood SES as related to survival, but the effect of both has not been studied. This study investigated the effect of individual and neighborhood SES simultaneously on mortality in gastric cancer patients in Taiwan.Materials and MethodsA study was conducted of 3,396 patients diagnosed with gastric cancer between 2002 and 2006. Each patient was followed for five years or until death. Individual SES was defined by income-related insurance premium (low, moderate, and high). Neighborhood SES was based on household income dichotomized into advantaged and disadvantaged areas. Multilevel logistic regression model was used to compare survival rates by SES group after adjusting for possible confounding factors.ResultsIn patients younger than 65 years, 5-year overall survival rates were lowest for those with low individual SES. After adjusting for patient characteristics (age, gender, Charlson Comorbidity Index Score), gastric cancer patients with high individual SES had 68% risk reduction of mortality (adjusted odds ratio [OR] of mortality, 0.32; 95% confidence interval [CI], 0.17–0.61). Patients aged 65 and above had no statistically significant difference in mortality rates by individual SES group. Different neighborhood SES did not statistically differ in the survival rates.ConclusionGastric cancer patients aged less than 65 years old with low individual SES have higher risk of mortality, even under an universal healthcare system. Public health strategies, education and welfare policies should seek to correct the inequality in gastric cancer survival, especially in those with lower individual SES.

“…One of the known clues t o the aetiology of gastric cancer is that the incidence of the disease tends to be higher among the poor sections of a community than among the wealthy (Clemmesen, 1965). This is not true for South Africa, where the white and African populations live on very different diets, but it is true for Denmark (Clemmesen and Nielsen, 1951), England and Wales (Registrar General, 1927, 1938, Norway (Torgersen and Petersen, 1956), and the USA (Cohart, 1954;Dorn and Cutler, 1959) where the dietary habits of different sections of the community are more alike.…”

The occupational mortality data in England It is suggested that the relationship between the mortality from gastric canccr and physical activity at work may be due in part to the fact that men whose occupation involves heavy work eat more and are consequently exposed to a greater quantity of carcinogens in their food.One of the known clues t o the aetiology of gastric cancer is that the incidence of the disease tends to be higher among the poor sections of a community than among the wealthy (Clemmesen, 1965). This is not true for South Africa, where the white and African populations live on very different diets, but it is true for Denmark (Clemmesen and Nielsen, 1951), England and Wales (Registrar General, 1927, 1938, Norway (Torgersen and Petersen, 1956), and the USA (Cohart, 1954;Dorn and Cutler, 1959) where the dietary habits of different sections of the community are more alike.In England and Wales the difference between the mortality from gastric cancer in the different socio-economic classes is substantial. In 1949-53, the standardized mortality ratio for men aged 20 to 64 years varied nearly three-fold, from 57 in social class I to 132 in social class V, a range that was exceeded only by the ratios for chronic bronchitis and gastric ulcer and equalled by pulmonary tuberculosis. The reasons for these differences are not, in general, known and no one reason is likely to be the explanation of all. One Received: 14 November, 1968.
