“…Este tipo de mutaciones es frecuentemente encontrado en tumores que se originan en tejidos con una historia de inflamación crónica. El poco avance que muestra esta reconsideración del problema por parte de la IARC respecto de su clasificación de 1991 ante el análisis de la evidencia reciente, coincide en cierto modo con una revisión previa (106) en la cual se concluye la existencia de diversos problemas metodológicos, particularmente en algunos estudios caso-control (sesgos potenciales en la fiabilidad de la medida del consumo -"recall bias", limitaciones en la exclusión de efectos de confusión potenciales con otros agentes como el tabaco y el alcohol). Finalmente, la IARC se limitó a recomendar que el consumo de mate se realizara a temperaturas inferiores a 65°C.…”

ResumenEl problema del cáncer es uno de los desafíos más relevantes de nuestra época. Como consecuencia de la transición demográfico-epidemiológica, el cáncer es actualmente una de las principales causas de muerte en el mundo y en Uruguay. Debido a que esta transición está aún en curso y con diferentes diná-micas alrededor del mundo, el problema del cáncer está cambiando en su escala y perfil. Se estima que el número de casos nuevos anuales pasará de alrededor de 14 millones en 2012 a más de 20 millones en 2030, y que casi dos tercios de esos casos ocurrirán en los países menos desarrollados. En tanto que estos últimos no cuentan con recursos similares a aquellos de los países desarrollados para enfrentar la enfermedad, esta situación plantea un desafío dramático para gobiernos y autoridades sanitarias.En Uruguay se diagnostican unos 13000 casos nuevos de cáncer (exceptuando al cáncer de piel distinto al melanoma), y más de 8000 pacientes mueren por esta enfermedad anualmente. Se examina, en particular, la situación epidemiológica de los cuatro tipos de cáncer más importantes: el cáncer de mama femenino, y los de próstata, pulmón y colo-recto, éstos dan cuenta de la mitad del total. Se analizan, además: el cáncer cervico-uterino y el cáncer de esófago. Las tasas estandarizadas por edad de mortalidad por cáncer (todos los sitios reunidos) muestran un descenso sostenido en las últimas décadas. No obstante, Uruguay exhibe en general tasas de incidencia comparables al conjunto de los países desarrollados, pero tasas de mortalidad más elevadas.

As a consequence of the demographic-epidemiologic transition, cancer is currently one of the leading causes of death, globally and in Uruguay. This transition is still in progress but with different dynamics around the world; therefore, the burden of cancer is changing its scale and profile. The projections indicate that the number of new cases will grow from 14 million in 2012 to more than 20 million in 2030, and that almost two thirds of them will take place in developing countries. Since less developed countries don`t have

“…We also found a positive association between green tea consumption and UADT cancers; evidence indicates that it is caused by thermal injury resulting from consuming tea at high temperatures. [6][7][8][9][10][11][12][13] Further study is needed to validate this association between coffee consumption and UADT cancers and to determine if consumption of tea at lower temperatures would also confer a protective effect against UADT cancers.…”

“…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

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.

Maté is a common beverage worldwide, especially in Latin America and certain parts of the Middle East. The dried leaves and stemlets of the plant are brewed and consumed hot or cold. Several studies have shown that maté drinking is a risk factor for a number of cancers including oral and pharyngeal cancers. Also, there is a strong evidence base linking maté drinking to oesophageal cancer. [1][2][3] Conversely, maté has been recognised for its antioxidant and anticancer properties. A recent study isolated di-caffeoylquinic acids (diCQAs) from maté leaves to explore their mechanism of action.The results suggest that diCQAs in maté could be potential anti-cancer agents and could mitigate other diseases associated with inflammation. 4 With such conflicting data, this review is very relevant and serves to advance our understanding of the association between maté drinking and the risk of oral and pharyngeal cancers.The review addressed the study question using a well thought out systematic approach.The authors' search strategy included the terms maté, maté drinking, maté beverage, cancer, oral cancer, tongue can-
