Citrus intake and risk of skin cancer in the European Prospective Investigation into Cancer and Nutrition cohort (EPIC)

Artículos Científicos

Citrus intake has been suggested to increase the risk of skin cancer. Although this relation is highly plausible biologically, epidemiologic evidence is lacking. We aimed to examine the potential association between citrus intake and skin cancer risk. EPIC is an ongoing multi-center prospective cohort initiated in 1992 and involving ~ 520,000 participants who have been followed-up…

Circulating vitamin D in relation to cancer incidence and survival of the head and neck and oesophagus in the EPIC cohort

Artículos Científicos

Experimental and epidemiological data suggest that vitamin D play a role in pathogenesis and progression of cancer, but prospective data on head and neck cancer (HNC) and oesophagus cancer are limited. The European Prospective Investigation into Cancer and Nutrition (EPIC) study recruited 385,747 participants with blood samples between 1992 and 2000. This analysis includes 497…

Circulating tryptophan metabolites and risk of colon cancer: results from case-control and prospective cohort studies

Artículos Científicos, Igualdad, Investigación, Mujeres EASP

Dysregulation of tryptophan metabolism has been linked to colorectal tumorigenesis, however, epidemiological studies investigating tryptophan metabolites in relation to colorectal cancer risk are limited. We studied associations of plasma tryptophan, serotonin, and kynurenine with colon cancer risk in two studies with cancer patients and controls, and in one prospective cohort: ColoCare Study (110 patients/153 controls),…

Circulating Sex Hormone Levels and Colon Cancer Risk in Men: A Nested Case-Control Study and Meta-analysis

Artículos Científicos, Cáncer, Igualdad, Investigación, Mujeres EASP

Background: Endogenous sex hormones may contribute to higher colorectal cancer incidence rates in men compared to women, but despite an increased number of studies, clear evidence is lacking. Methods: We conducted a comprehensive nested case-control study of circulating concentrations of sex hormones, sex hormone precursors and sex hormone binding globulin (SHBG) in relation to subsequent…

Circulating plasma phospholipid fatty acids and risk of pancreatic cancer in a large European cohort

Artículos Científicos

There are both limited and conflicting data on the role of dietary fat and specific fatty acids in the development of pancreatic cancer. In this study, we investigated the association between plasma phospholipid fatty acids and pancreatic cancer risk in the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort. The fatty acid composition was…

Circulating Osteopontin and Prediction of Hepatocellular Carcinoma Development in a Large European Population

Artículos Científicos

We previously identified osteopontin (OPN) as a promising marker for the early detection of hepatocellular carcinoma (HCC). In this study, we investigated the association between prediagnostic circulating OPN levels and HCC incidence in a large population-based cohort. A nested case–control study was conducted within the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort. During…

Circulating Isovalerylcarnitine and Lung Cancer Risk: Evidence from Mendelian Randomization and Pre-Diagnostic Blood Measurements

Artículos Científicos

Background: Tobacco exposure causes 8 of 10 lung cancers, and identifying additional risk factors is challenging due to confounding introduced by smoking in traditional observational studies. Materials and Methods: We used Mendelian randomization (MR) to screen 207 metabolites for their role in lung cancer predisposition using independent genome-wide-association studies (GWAS) of blood metabolite levels (n…

Circulating insulin‐like growth factor I in relation to melanoma risk in the European Prospective Investigation into Cancer and Nutrition

Artículos Científicos

Insulin‐like growth factor (IGF‐I) regulates cell proliferation and apoptosis, and is thought to play a role in tumour development. Previous prospective studies have shown that higher circulating concentrations of IGF‐I are associated with a higher risk of cancers at specific sites, including breast and prostate. No prospective study has examined the association between circulating IGF‐I…

Circulating inflammatory biomarkers, adipokines and breast cancer risk—a case-control study nested within the EPIC cohort

Artículos Científicos, Cáncer, Mujeres EASP

Background Inflammation has been hypothesized to play a role in the development and progression of breast cancer and might differently impact breast cancer risk among pre and postmenopausal women. We performed a nested case-control study to examine whether pre-diagnostic circulating concentrations of adiponectin, leptin, c-reactive protein (CRP), tumour necrosis factor-α, interferon-γ and 6 interleukins were…

Circulating inflammatory and immune response proteins and endometrial cancer risk: a nested case-control study and Mendelian randomization analyses

Artículos Científicos, Cáncer, Igualdad, Investigación, Mujeres EASP

Background Inflammation and immune dysregulation are hypothesized contributors to endometrial carcinogenesis; however, the precise underlying mechanisms remain unclear. Methods We measured pre-diagnostically 152 plasma protein biomarkers in 624 endometrial cancer case-control pairs nested within the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort. Odds ratios (ORs) were estimated using conditional logistic regression, accounting for…
