    Adequate intake of copper and zinc, two essential micronutrients, are important for antioxidant functions. Their imbalance may have implications for development of diseases like colorectal cancer (CRC), where oxidative stress is thought to be etiologically involved. As evidence from prospective epidemiologic studies is lacking, we conducted a case-control study nested within the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort to investigate the association between circulating levels of copper and zinc, and their calculated ratio, with risk of CRC development. Copper and zinc levels were measured by reflection X-ray fluorescence spectrometer in 966 cases and 966 matched controls. Multivariable adjusted odds ratios (OR) and 95% confidence intervals (CI) were calculated using conditional logistic regression and are presented for the fifth versus first quintile. Higher circulating concentration of copper was associated with a raised CRC risk (OR = 1.50; 95% CI: 1.06, 2.13; P-trend = 0.02) whereas an inverse association with cancer risk was observed for higher zinc levels (OR = 0.65; 95% CI: 0.43, 0.97; P-trend = 0.07). Consequently, the ratio of copper/zinc was positively associated with CRC (OR = 1.70; 95% CI: 1.20, 2.40; P-trend = 0.0005). In subgroup analyses by follow-up time, the associations remained statistically significant only in those diagnosed within 2 years of blood collection. In conclusion, these data suggest that copper or copper levels in relation to zinc (copper to zinc ratio) become imbalanced in the process of CRC development. Mechanistic studies into the underlying mechanisms of regulation and action are required to further examine a possible role for higher copper and copper/zinc ratio levels in CRC development and progression

    Polyphenols have been shown to exert biological activity in experimental models of colon cancer; however, human data linking specific polyphenols to colon cancer is limited. We assessed the relationship between pre-diagnostic plasma polyphenols and colon cancer risk in a case-control study nested within the European Prospective Investigation into Cancer and Nutrition study. Using high pressure liquid chromatography coupled to tandem mass spectrometry, we measured concentrations of 35 polyphenols in plasma from 809 incident colon cancer cases and 809 matched controls. We used multivariable adjusted conditional logistic regression models that included established colon cancer risk factors. The false discovery rate (qvalues ) was computed to control for multiple comparisons. All statistical tests were two-sided. After false discovery rate correction and in continuous log2 -transformed multivariable models, equol (odds ratio [OR] per log2 -value, 0.86, 95% confidence interval [95% CI] = 0.79-0.93; qvalue = 0.01) and homovanillic acid (OR per log2 -value, 1.46, 95% CI = 1.16-1.84; qvalue = 0.02) were associated with colon cancer risk. Comparing extreme fifths, equol concentrations were inversely associated with colon cancer risk (OR = 0.61, 95% CI = 0.41-0.91, ptrend = 0.003), while homovanillic acid concentrations were positively associated with colon cancer development (OR = 1.72, 95% CI = 1.17-2.53, ptrend < 0.0001). No heterogeneity for these associations was observed by sex and across other colon cancer risk factors. The remaining polyphenols were not associated with colon cancer risk. Higher equol concentrations were associated with lower risk, and higher homovanillic acid concentrations were associated with greater risk of colon cancer. These findings support a potential role for specific polyphenols in colon tumorigenesis

    Background: Skin cancers are the most common cancers in white-skinned populations. While exposure to solar radiation is the best known risk factor, few studies have allowed a direct comparison of exposure profiles associated with these tumours within a single population, and little is known about the determinants of sun exposure behaviors. Moreover, although antioxidants, which have the ability of scavenging free radicals, are potential candidates for the chemoprevention of skin cancers, the current state of the literature does not allow to make clear conclusions with regards to their role on skin cancer risk.Objectives: The objective of this thesis is to examine the associations between UV exposures and skin cancer risk, to describe the profiles associated with several sun exposure behaviors, and to explore the potential associations between antioxidant dietary supplements and the risk of skin cancer in the French E3N (Étude ÉpidĂ©miologique auprĂšs de femmes de l’Éducation Nationale) study.Results: Our results suggest that the three types of skin cancers are associated with different sun exposure profiles and that sunscreen use, sunbed use, and solar supplement use are associated with both healthy and risky behaviors. In addition, our findings suggest that the use of solar supplements and vitamin E supplements is associated with an increased risk of non-melanoma skin cancers.Conclusions: This work emphasizes the importance of prevention to reduce the prevalence of skin cancers as well as the need to better understand the profiles associated with sun exposure behaviors and their potential impact on the associations with the risk of skin cancer. Furthermore, our results do not support the hypothesis of a protective effect of the consumption of antioxidant dietary supplements on the risk of skin cancer and call for more research in order to better understand their long-term effects on health.Contexte : Les cancers cutanĂ©s sont les cancers les plus frĂ©quents dans les populations de peau blanche. Si l’exposition aux rayonnements ultraviolets est le facteur de risque le plus connu, peu d’études ont permis une comparaison directe des profils d’exposition solaire associĂ©s Ă  ces tumeurs dans une mĂȘme population, et les dĂ©terminants des comportements d’exposition solaire restent peu connus Ă  ce jour. Par ailleurs, bien que les antioxydants, ayant la capacitĂ© de neutraliser les radicaux libres, reprĂ©sentent des candidats potentiels pour la chimioprĂ©vention des cancers cutanĂ©s, l’état actuel des connaissances ne permet pas d’émettre de conclusion claire en ce qui concerne leur rĂŽle vis-Ă -vis du risque de cancers cutanĂ©s.Objectif : L’objectif de cette thĂšse est de prĂ©ciser le lien existant entre l’exposition solaire et le risque de cancers cutanĂ©s, d’explorer les profils associĂ©s Ă  certains comportements d’exposition solaire et d’étudier les associations potentielles entre complĂ©ments alimentaires en antioxydants et risque de cancers cutanĂ©s dans l’étude française E3N (Étude ÉpidĂ©miologique auprĂšs de femmes de l’Éducation Nationale).RĂ©sultats : Nos rĂ©sultats suggĂšrent que les trois types de cancers cutanĂ©s sont associĂ©s Ă  diffĂ©rents profils d'exposition solaire et que l’utilisation de crĂšme solaire, de lampes UV et de complĂ©ments solaires sont associĂ©s Ă  plusieurs habitudes favorables et dĂ©favorables pour la santĂ©. De plus, nos rĂ©sultats suggĂšrent que les consommations de complĂ©ments solaires et de complĂ©ments en vitamine E sont associĂ©es Ă  un risque accru de carcinomes cutanĂ©s.Conclusion : Ce travail souligne l’importance de la prĂ©vention pour rĂ©duire la prĂ©valence des cancers cutanĂ©s ainsi que la nĂ©cessitĂ© de mieux comprendre les profils associĂ©s Ă  diffĂ©rents comportements d’exposition solaire et leur impact potentiel sur les associations avec le risque de cancers cutanĂ©s. Par ailleurs, nos rĂ©sultats ne soutiennent pas l’hypothĂšse d’un effet protecteur de la consommation de complĂ©ments alimentaires en antioxydants vis-Ă -vis du risque de cancers cutanĂ©s et appellent Ă  davantage de recherches afin de mieux comprendre leurs effets Ă  long terme sur la santĂ©

    29 p.ill.,Het Federaal Kenniscentrum voor de Gezondheidszorg (KCE) publiceert een set van 15 kwaliteitsindicatoren voor de behandeling van eierstokkanker. Dit maakt deel uit van een continu proces om de kwaliteit van de kankerzorg in BelgiĂ« te verbeteren en is reeds met succes toegepast bij andere types kanker. De 15 indicatoren werden berekend voor alle ziekenhuizen, die een individueel feedbackrapport van de Stichting Kankerregister zullen ontvangen, zodat zij hun sterke en zwakke punten kunnen identificeren en waar nodig de zorg verbeteren. In een tweede deel toont de studie aan dat de kans van patiĂ«nten op overleven duidelijk hoger is in ziekenhuizen die elk jaar een groot aantal patiĂ«nten behandelen. Het KCE pleit er dan ook voor de behandeling van eierstokkanker in een beperkt aantal referentiecentra te concentreren. Bij de erkenning van deze referentiecentra mag het aantal behandelde patiĂ«nten zeker niet het enige criterium zijn.VOORWOORD 1 -- &#61550; KERN-BOODSCHAPPEN 2 -- 1.

    29 p.ill.,Le Centre fĂ©dĂ©ral d’Expertise des Soins de santĂ© (KCE) publie un ensemble de 15 indicateurs de qualitĂ© pour la prise en charge du cancer de l’ovaire. Cette dĂ©marche s’inscrit dans un processus continu d’amĂ©lioration de la qualitĂ© des soins en oncologie en Belgique et a dĂ©jĂ  Ă©tĂ© appliquĂ©e avec fruit pour d’autres types de cancers. Les rĂ©sultats des 15 indicateurs ont Ă©tĂ© calculĂ©s au niveau national, et tous les hĂŽpitaux recevront ensuite un rapport d'Ă©valuation individuel envoyĂ© par la Fondation Registre du Cancer. Cela leur permettra d'identifier leurs points forts et leurs points faibles et d'amĂ©liorer leurs pratiques si nĂ©cessaire. Dans une seconde partie, l’étude a dĂ©montrĂ© que les chances de survie sont nettement plus Ă©levĂ©es dans les hĂŽpitaux qui traitent un grand nombre de patientes chaque annĂ©e. Le KCE plaide donc pour une concentration de la prise en charge du cancer de l’ovaire dans un nombre limitĂ© de centres de rĂ©fĂ©rence. La reconnaissance de ces centres de rĂ©fĂ©rence ne doit cependant pas se baser sur le seul nombre de patientes traitĂ©es.PRÉFACE 1 -- MESSAGES CLÉS 2 -- 1. CONTEXTE ET OBJECTIFS 6 -- 1.1.
