Menée en France à partir des données 2010 de l'enquête "baromètre cancer" de l'Institut national de prévention et d'éducation pour la santé portant sur 3 359 participants âgés de 15 à 75 ans, cette étude analyse leurs perceptions des risques de cancer liés à la consommation d'alcool

Alcohol and cancer : risk perception and risk denial beliefs among the French general population

Bocquier, A. ; Fressard, L. ; Verger, P. ; Legleye, S. ; Peretti-Watel, P.

Background : Worldwide, millions of deaths each year are attributed to alcohol. We sought to examine French people’s beliefs about the risks of alcohol, their correlates, and their associations with alcohol use. Methods : Data came from the 2010 Baromètre Cancer survey, a random cross-sectional telephone survey of the French general population (n = 3359 individuals aged 15–75 years). Using principal component analysis of seven beliefs about alcohol risks, we built two scores (one assessing risk [...]

Menée à partir de questionnaires auprès de 623 patients atteints d'un cancer de la tête et du cou et auprès de 731 témoins, cette étude évalue l'association entre la pratique régulière d'une activité physique de loisir et le risque de cancer de la tête et du cou

Background : Although substantial evidence supports a 20–30% risk reduction of colon cancer, breast cancer, and endometrial cancer by physical activity (PA), the evidence for head and neck cancer (HNC) is limited. Three published studies on the association between PA and HNC have generated inconsistent results. The current study examined the association between recreational PA (RPA) and HNC risk with a more detailed assessment on the intensity, frequency, duration, and total years of RPA. [...]

Cet article passe en revue les études épidémiologiques, histopathologiques et moléculaires sur l'adénome festonné sessile du côlon-rectum ainsi que les études sur leur détection endoscopique et leur chimioprévention

Sessile Serrated Polyps and Colon Cancer Prevention

Rashtak, Shahrooz ; Rego, Rafaela ; Sweetser, Seth R. ; Sinicrope, Frank A.

Evidence suggests that up to one fifth of colorectal carcinomas develop from serrated polyps, named for their pattern of colonic crypts, and include the sessile serrated adenoma/polyp (SSA/P) that has malignant potential. SSA/Ps are typically located in the proximal colon and have molecular features of hypermethylation of CpG islands in gene promoters and activating point mutations (V600E) in the BRAF oncogene. Both of these features are seen in sporadic colorectal carcinomas with [...]

Menée en Ontario (Canada) à partir d'une enquête auprès de 2 414 fumeurs adultes, cette étude analyse l'influence de la proximité et du nombre de débits de tabac, situés à moins de 500 m du domicile, sur les tentatives d'arrêt du tabagisme et le risque de rechute

Tobacco retail availability and risk of relapse among smokers who make a quit attempt : a population-based cohort study

Chaiton, Michael O. ; Mecredy, Graham ; Cohen, Joanna

Introduction : The availability of tobacco is thought to influence smoking behaviour, but there are few longitudinal studies examining if the location and number of tobacco outlets has a prospective impact on smoking cessation. Methods : The Ontario Tobacco Survey, a population-representative sample of Ontario adult smokers who were followed every 6 months for up to 3 years, was linked with tobacco outlet location data from the Ontario Ministry of Health. Proximity (distance), threshold (at [...]
