Epidemiological studies regarding the associations of tea and coffee consumption with esophageal cancer (EC) risk are still inconsistent and this meta-analysis was conducted to examine these associations. PubMed, ISI -Web of Science, China National Knowledge Infrastructure (CNKI), and Chinese VIP database up to October 2011 were searched and manual search for reference lists of relevant studies were conducted. Random effects model was used to pool the odds ratios (OR). Twenty-four case-control… 

Green Tea Consumption and Esophageal Cancer Risk: A Meta-analysis

Green tea consumption could be a protective factor for esophageal cancer, and pooled relative risks or odds ratios with 95% confidence intervals (CIs) were calculated using random effects models.

Hot Tea Consumption and Esophageal Cancer Risk: A Meta-Analysis of Observational Studies

This meta-analysis showed that people who drank hot tea had a significantly increased risk of Esophageal squamous cell carcinoma (ESCC), but no significant association for EAC.

Coffee and cancer risk: A meta-analysis of prospective observational studies

Coffee intake was associated with reduced risk of oral, pharynx, liver, colon, prostate, endometrial cancer and melanoma and increased lung cancer risk.

Tea consumption reduces the risk of oral cancer : a systematic review and meta-analysis

It is suggested that tea consumption may reduce the risk of oral cancer, and further high-quality cohort or case-control studies are needed to explore the protective effect of tea on oral cancer.

Tea and coffee consumption and risk of esophageal cancer: The European prospective investigation into cancer and nutrition study

Data did not show a significant association between tea and coffee consumption and EC, EAC and ESCC, although a decreased risk of ESCC among men and current smokers is suggested, but need to be confirmed in further prospective studies including more cases.

Coffee drinking and cancer risk: an umbrella review of meta-analyses of observational studies

There is highly suggestive evidence for an inverse association between coffee intake and risk of liver and endometrial cancer and further research is needed to provide more robust evidence for cancer at other sites.

The association between coffee consumption and bladder cancer incidence in a pooled analysis of the Miyagi Cohort Study and Ohsaki Cohort Study

There is a significant inverse association between coffee consumption and the risk of bladder cancer, and the inverse association remained even after stratification for smoking status.

Very hot tea drinking increases esophageal squamous cell carcinoma risk in a high-risk area of China: a population-based case–control study

Very hot tea drinking significantly increases the risk of esophageal squamous cell carcinoma among Chinese men, which is particularly evident among alcohol drinkers.

Modifiable factors and esophageal cancer: a systematic review of published meta-analyses

This work reinforces the importance of a separate assessment of EC subtypes to allow for a proper evaluation of incidence trends and planning of prevention/control interventions.



Green Tea and Black Tea Consumption and Prostate Cancer Risk: An Exploratory Meta-Analysis of Observational Studies

It is supported that green tea but not black tea may have a protective effect on PCa, especially in Asian populations, and further research regarding green tea consumption across different regions apart from Asia is needed.

Green tea consumption and risk of stomach cancer: A meta‐analysis of epidemiologic studies

No preventive effect on stomach cancer was seen for the highest green tea consumption in the meta‐analysis of the recent cohort studies, and further clinical trials are needed.

Tea and coffee consumption and the risk of digestive tract cancers: data from a comparative case-referent study in Japan

The results suggest the potential for protective effect against site-specific digestive tract cancer by consumption of green tea and coffee, although most associations are limited only to the upper category of intake and have no clear explanation for site- specificity.

Coffee and cancers of the upper digestive and respiratory tracts: meta-analyses of observational studies.

Coffee drinking is inversely related to OP cancer risk, while there is no relation with laryngeal cancer, ESCC and EAC.

Green tea drinking habits and esophageal cancer in southern China: a case-control study.

In the South China context, drinking tea at high temperature significantly increases risk of esophageal cancer, especially in drinkers and smokers.

Coffee consumption and the risk of oral, pharyngeal, and esophageal cancers in Japan: the Miyagi Cohort Study.

Coffee consumption was associated with a lower risk of oral, pharyngeal, and esophageal cancers, even in the group at high risk of these cancers.

Smoking, Alcohol Drinking, Green Tea Consumption and the Risk of Esophageal Cancer in Japanese Men

Among the variables studied, smoking has the largest public health impact on esophageal cancer incidence in Japanese men, followed by alcohol drinking and green tea drinking.
