Abstract
Objective
To compute the burden of cancer attributable to current and former alcohol consumption in eight European countries based on direct relative risk estimates from a cohort study.

Design
Combination of prospective cohort study with representative population based data on alcohol exposure.

Setting Eight countries (France, Italy, Spain, United Kingdom, the Netherlands, Greece, Germany, Denmark) participating in the European Prospective Investigation into Cancer and Nutrition (EPIC) study.

Participants 109 118 men and 254 870 women, mainly aged 37-70.

Main outcome measures
Hazard rate ratios expressing the relative risk of cancer incidence for former and current alcohol consumption among EPIC participants. Hazard rate ratios combined with representative information on alcohol consumption to calculate alcohol attributable fractions of causally related cancers by country and sex. Partial alcohol attributable fractions for consumption higher than the recommended upper limit (two drinks a day for men with about 24 g alcohol, one for women with about 12 g alcohol) and the estimated total annual number of cases of alcohol attributable cancer.

Results
If we assume causality, among men and women, 10% (95% confidence interval 7 to 13%) and 3% (1 to 5%) of the incidence of total cancer was attributable to former and current alcohol consumption in the selected European countries. For selected cancers the figures were 44% (31 to 56%) and 25% (5 to 46%) for upper aerodigestive tract, 33% (11 to 54%) and 18% (−3 to 38%) for liver, 17% (10 to 25%) and 4% (−1 to 10%) for colorectal cancer for men and women, respectively, and 5.0% (2 to 8%) for female breast cancer. A substantial part of the alcohol attributable fraction in 2008 was associated with alcohol consumption higher than the recommended upper limit: 33 037 of 178 578 alcohol related cancer cases in men and 17 470 of 397 043 alcohol related cases in women.

Conclusions
In western Europe, an important proportion of cases of cancer can be attributable to alcohol consumption, especially consumption higher than the recommended upper limits. These data support current political efforts to reduce or to abstain from alcohol consumption to reduce the incidence of cancer.

El consumo de alcohol es responsable de más de 50.000 nuevos casos de cáncer al año en Europa
JANO.es y agencias · 11 Abril 2011 10:34

.Existe una relación causal entre el consumo de alcohol, sobre todo cuando es excesivo, y los tumores de hígado, mama, colon, intestino, boca, cuello y esófago.


Científicos del Instituto Alemán de Nutrición Humana aseguran que el alcohol causa cada año en Europa más de 50.000 nuevos casos de cáncer, sobre todo cuando se consume por encima de los límites recomendados, según un amplio estudio cuyos resultados publica el British Medical Journal.

La Agencia Internacional de Investigación sobre el Cáncer (AIIC), que forma parte de la Organización Mundial de la Salud (OMS), ha reconocido que existe una relación causal entre el consumo de alcohol y los tumores de hígado, mama, colon o intestino, al igual que con otros del tracto digestivo, como el de boca, garganta y esófago.

De hecho, se estima que casi el 10% de todos los cánceres registrados en hombres y el 3% en las mujeres en Europa occidental los causa el elevado consumo de alcohol.

En esta investigación se tomaron los datos de un estudio europeo llamado Investigación Prospectiva Europea sobre el Cáncer, en el que participaron 363.988 hombres y mujeres de ocho países europeos, entre ellos España, con edades comprendidas entre los 35 y los 70 años.

Gracias a estos datos, pudieron realizar un seguimiento de estos pacientes desde mediados de los años 90 hasta 2008, año en el que detectaron un total de 79.100 nuevos casos de determinados tipos de cáncer, de los cuales unos 57.600 casos estaban relacionados con la bebida, y unos 50.400 por una ingesta de alcohol mayor de lo recomendado.

De hecho, más de la mitad de los casos, unos 33.000, se dieron en varones que ingerían más de dos copas de alcohol al día.

La ingesta alcohólica en mujeres en estos ocho países causó unos 21.500 casos de cáncer del tracto digestivo superior, hígado, mama y colorrectal, de los cuales más del 80% (unos 17.400) se dieron en quienes bebían más de una copa al día.

“Muchos casos de cáncer pudieron haberse evitado si el consumo de alcohol se viera limitado a dos bebidas alcohólicas al día en hombres y una al día en las mujeres”, aseguró la principal autora del estudio, Madlen Schutze, reconociendo que “esas son las recomendaciones de muchas organizaciones sanitarias”. No obstante, asegura que “si la población redujera el consumo de alcohol por debajo de estas recomendaciones se prevendrían muchos más casos”.

Una bebida alcohólica media contiene aproximadamente 12 gramos de alcohol y equivale a una copa de vino de 125 mililitros o a media pinta de cerveza.

El problema, según añade la directora de información sanitaria del Cancer Research UK, Sara Hiom, es que “muchas personas no saben que beber alcohol puede incrementar su riesgo de sufrir cáncer”.

De hecho, en Reino Unido el cáncer bucal se ha vuelto más común en los últimos diez años y “una razón podrían ser niveles de ingesta alcohólica más altos, como refleja el estudio”.
