“…but in Sun`s study there was no significant relationship between irregular lunch-time and risk of gastric cardia cancer (Sun et al, 2013). It seems that irregular meal time leads to gastritis or gastro duodenal ulcers (Lim et al, 2013), if these predisposing factors presented for long time with no treatments, we could expect gastric cancer occurrence.…”

Golestan province has a reputation for relatively high incidence rates of gastric cancer in Iran. Along with dietary, lifestyle and environmental influential factors, soil selenium and high levels of pesticide used may exert influence in this region. The present study was designed for modeling the influential predictors on incidence of gastric cancer in Golestan. All registered cases of gastric cancer from March 2009 to March 2010 (49 females and 107 males) were investigated. Data were gathered by both check list and researcher made questionnaire (demographic, clinical and lifestyle characteristics) and analysed using logistic regression. Mean (±SD) age at diagnosis was 62.9±13.8 years. CIR and ASR of gastric cancer showed 9.16 and 13.9 per 100,000 people, respectively. Based on univariate logistic regression, a history of smoking (OR= 2.076), unwashed hands after defecation (OR= 2.612), history of cancer in relatives (OR= 2.473), history of gastric cancer in first-degree relatives (OR= 2.278), numbers of gastric cancers in first-degree relatives (OR= 2.078), history of X-ray and dye exposure (OR= 2.395), history of CT scan encounter (OR= 2.915), improper food habits (OR= 3.320), specific eating behavior (OR= 0.740), consumption of probable high risk foods (OR= 2.942), charred flesh (OR= 1.945), and animal fat (OR= 2.716) were confirmed as a risk factors. Changes in lifestyle may be expected to increase gastric cancer incidence dramatically in the near future. Therefore, appropriate educational interventions should be designed and implemented by competent authorities

“…Along with other studies, results showed that specific eating behaviors (effective food chewing, eating slowly (speed of eating)), were identified as a preventive factor (Gao et al, 1999;Sierpinska et al, 2007;Sun et al, 2013).…”

“…The essence of risk modeling is to obtain accurate relative and attributable risk estimates for etiologic factors, e.g., demographics, reproductive history, smoking, dietary patterns and medications (Sun et al, 2013). This depends on a clear understanding of the nature of all the individual factors involved and interactions between them.…”

The big gap between efficacy of population level prevention and expectations due to heterogeneity and complexity of cancer etiologic factors calls for selective yet personalized interventions based on effective risk assessment. This paper documents our research protocol aimed at refining and validating a two-stage and webbased cancer risk assessment tool, from a tentative one in use by an ongoing project, capable of identifying individuals at elevated risk for one or more types of the 80% leading cancers in rural China with adequate sensitivity and specificity and featuring low cost, easy application and cultural and technical sensitivity for farmers and village doctors. The protocol adopted a modified population-based case control design using 72, 000 non-patients as controls, 2, 200 cancer patients as cases, and another 600 patients as cases for external validation. Factors taken into account comprised 8 domains including diet and nutrition, risk behaviors, family history, precancerous diseases, related medical procedures, exposure to environment hazards, mood and feelings, physical activities and anthropologic and biologic factors. Modeling stresses explored various methodologies like empirical analysis, logistic regression, neuro-network analysis, decision theory and both internal and external validation using concordance statistics, predictive values, etc..

“…Evidence indicates that the recurrent thermal injury to the mucosa that occurs with the consumption of heated beverages such as coffee, tea and mate causes upper aerodigestive tract (UADT) cancers. [6][7][8][9][10][11][12][13] In a report published jointly by the World Cancer Research Fund and the American Institute for Cancer Research, the panel concluded that although evidence was lacking, high-temperature drinks were a limited or suggestive cause of esophageal cancer. 14 Epidemiologic studies of the association between UADT and cancer and coffee consumption have been inconsistent, although a recent meta-analysis found that coffee consumption is inversely associated with cancer of the oropharynx and esophagus.…”

Coffee and green tea consumption is associated with upper aerodigestive tract cancer in Japan

et al. 2013

The impact of coffee and green tea consumption on upper aerodigestive tract (UADT) cancer risk has not been established. Evaluation of the possible anticarcinogenic properties of their ingredients is confounded by the potential increase in risk owing to the high temperatures at which these beverages are generally consumed. We conducted a case-control study to evaluate the association between coffee and tea consumption and the risk of UADT cancer. The study enrolled 961 patients with UADT cancer and 2,883 noncancer outpatients who visited Aichi Cancer Center between 2001 and 2005. Information on coffee and green tea consumption and other lifestyle factors was collected via a self-administered questionnaire. Consumption of three or more cups of coffee per day had a significant inverse association with UADT cancer [odds ratio (OR) 0.73, 95% confidence interval (CI) 0.55-0.96]. In contrast, consumption of three or more cups of green tea per day had a significant positive association with UADT cancer (OR 1.39, 95% CI 1.13-1.70). These associations were evident for head and neck cancer but not for esophageal cancer. The association of coffee consumption with head and neck cancer was observed only among never smokers and alcohol drinkers. Similarly, the association of green tea consumption was observed among never smokers and never alcohol drinkers. No change in these associations was seen on stratification by each confounding factors. These findings suggest that consumption of coffee might be associated with a decreased risk of UADT cancer, whereas that of green tea might be associated with an increased risk.Coffee and tea are the most frequently consumed beverages in the world. 1,2 Coffee is extracted from the roasted seeds (coffee beans) of several species of coffee plants (primarily Coffea arabica and Coffea canephora), which are cultivated in tropical countries. Green tea, the most commonly consumed tea product in Japan, is brewed from the leaves of the tea plant (Camellia sinensis). Differences among types of tea, such as green tea, black tea and oolong tea, result from differences in the degree of fermentation of their leaves. 3 Previous studies suggest that the consumption of coffee and green tea may provide a protective effect against cancer owing to their anticarcinogenic components.
