We analysed trends in incidence for in situ and invasive melanoma in some European countries during the period 1995–2012, stratifying for lesion thickness.
Individual anonymised data from ...population-based European cancer registries (CRs) were collected and combined in a common database, including information on age, sex, year of diagnosis, histological type, tumour location, behaviour (invasive, in situ) and lesion thickness. Mortality data were retrieved from the publicly available World Health Organization database.
Our database covered a population of over 117 million inhabitants and included about 415,000 skin lesions, recorded by 18 European CRs (7 of them with national coverage). During the 1995–2012 period, we observed a statistically significant increase in incidence for both invasive (average annual percent change (AAPC) 4.0% men; 3.0% women) and in situ (AAPC 7.7% men; 6.2% women) cases.
The increase in invasive lesions seemed mainly driven by thin melanomas (AAPC 10% men; 8.3% women). The incidence of thick melanomas also increased, although more slowly in recent years. Correction for lesions of unknown thickness enhanced the differences between thin and thick cases and flattened the trends. Incidence trends varied considerably across registries, but only Netherlands presented a marked increase above the boundaries of a funnel plot that weighted estimates by their precision. Mortality from invasive melanoma has continued to increase in Norway, Iceland (but only for elder people), the Netherlands and Slovenia.
•This study is the most recent analysis of melanoma trends in Europe by lesion thickness.•We analysed about 415,000 cases incident between 1995 and 2012 from 13 European countries.•Results showed that the incidence of invasive melanoma continues to increase, mainly due to thin lesions.•There was a large variation in trends among countries, with the greatest increase in the Netherlands.•Mortality from invasive melanoma continued to increase in some countries.

Factors linked to glucose metabolism are involved in the etiology of several cancers. High glycemic index (GI) or high glycemic load (GL) diets, which chronically raise postprandial blood glucose, ...may increase cancer risk by affecting insulin-like growth factor. We prospectively investigated cancer risk and dietary GI/GL in the EPIC-Italy cohort. After a median 14.9 years, 5112 incident cancers and 2460 deaths were identified among 45,148 recruited adults. High GI was associated with increased risk of colon and bladder cancer. High GL was associated with: increased risk of colon cancer; increased risk of diabetes-related cancers; and decreased risk of rectal cancer. High intake of carbohydrate from high GI foods was significantly associated with increased risk of colon and diabetes-related cancers, but decreased risk of stomach cancer; whereas high intake of carbohydrates from low GI foods was associated with reduced colon cancer risk. In a Mediterranean population with high and varied carbohydrate intake, carbohydrates that strongly raise postprandial blood glucose may increase colon and bladder cancer risk, while the quantity of carbohydrate consumed may be involved in diabetes-related cancers. Further studies are needed to confirm the opposing effects of high dietary GL on risks of colon and rectal cancers.

This study examined the association of body-mass index (BMI), waist circumference, and waist-to-hip ratio with the risk of death among more than 350,000 European subjects who had no major chronic ...diseases. The data suggest that both general and abdominal adiposity are associated with the risk of death and support the use of waist circumference or waist-to-hip ratio in addition to BMI for assessment of the risk of death, particularly among persons with a lower BMI.
This study suggests that both general and abdominal adiposity are associated with the risk of death and supports the use of waist circumference or waist-to-hip ratio for assessment of the risk of death.
Abdominal obesity is more closely associated with the risk of several chronic diseases than is gluteofemoral obesity, and large studies have suggested that waist circumference or the waist-to-hip ratio, as indicators of abdominal obesity, may be better predictors of the risk of disease than the body-mass index (BMI, the weight in kilograms divided by the square of the height in meters), an indicator of general adiposity.

Current guidelines with respect to obesity recommend the measurement of waist circumference in persons with a BMI between 25.0 and 34.9 and propose cutoff points for waist circumference of 102 cm in men . . .
In Italy, some of the highest incidence rates (IRs) of thyroid cancer (TC) worldwide have been reported.
TC cases <85 years of age reported to Italian cancer registries during 1991–2005 were ...included. Age-standardized IRs were computed for all TC and age–period–cohort effects were estimated for papillary TC.
IRs of TC were twofold higher in 2001–2005 than in 1991–1995 (18 and 8 per 100000 women, 6 and 3 per 100000 men, respectively). Increases were similar in the two sexes and nearly exclusively due to papillary TC. Increases of papillary TC by birth cohort were found in both sexes and among all age groups between 20 and 79 years. Age–period–cohort models showed a strong period effect in both sexes (rate ratio for 2001–2009 versus 1991–1995 = 2.5 in women and 2.3 in men), although IRs peaked at an earlier age in women (45–49 years) than men (65–69 years).
The strength of the period effect in both sexes and the earlier onset in women than men strongly implicated increased medical surveillance in the upward trends of papillary TC incidence in Italy. The consequences of the current intense search for TC on morbidity and possible overtreatment, especially among young women, should be carefully evaluated.

Abstract
Background and Aims
Population-based prospective cohort studies investigating fibre intake and development of inflammatory bowel disease are lacking. Our aim was to investigate the ...association between fibre intake and the development of Crohn’s disease CD and ulcerative colitis UC in a large European population.
Methods
In total, 401326 participants, aged 20–80 years, were recruited in eight countries in Europe between 1991 and 1998. At baseline, fibre intake total fibres, fibres from fruit, vegetables and cereals was recorded using food frequency questionnaires. The cohort was monitored for the development of inflammatory bowel disease. Each case was matched with four controls and odds ratios ORs for the exposures were calculated using conditional logistic regression. Sensitivity analyses according to smoking status were computed.
Results
In total, 104 and 221 participants developed incident CD and UC, respectively. For both CD and UC, there were no statistically significant associations with either quartiles, or trends across quartiles, for total fibre or any of the individual sources. The associations were not affected by adjusting for smoking and energy intake. Stratification according to smoking status showed null findings apart from an inverse association with cereal fibre and CD in non-smokers Quartile 4 vs 1 OR = 0.12, 95% confidence interval = 0.02–0.75, p = 0.023, OR trend across quartiles = 0.50, 95% confidence interval = 0.29–0.86, p = 0.017.
Conclusion
The results do not support the hypothesis that dietary fibre is involved in the aetiology of UC, although future work should investigate whether there may be a protective effect of specific types of fibre according to smoking status in CD.
A carbohydrate‐rich diet, resulting in high blood glucose and insulin, has been hypothesized as involved in colorectal cancer etiology. We investigated dietary glycemic index (GI) and glycemic load ...(GL), in relation to colorectal cancer, in the prospectively recruited EPIC‐Italy cohort. After a median 11.7 years, 421 colorectal cancers were diagnosed among 47,749 recruited adults. GI and GL were estimated from validated food frequency questionnaires. Multivariable Cox modeling estimated hazard ratios (HRs) for associations between colorectal cancer and intakes of total, high GI and low GI carbohydrate and GI and GL. The adjusted HR of colorectal cancer for highest versus lowest GI quartile was 1.35; 95% confidence interval (CI) 1.03–1.78; p trend 0.031. Increasing high GI carbohydrate intake was also significantly associated with increasing colorectal cancer risk (HR 1.45; 95% CI 1.04–2.03; p trend 0.034), whereas increasing low GI carbohydrate was associated with reducing risk (HR 0.73; 95% CI 0.54–0.98; p trend 0.033). High dietary GI and high GI carbohydrate were associated with increased risks of cancer at all colon sites (HR 1.37; 95% CI 1.00–1.88, HR 1.80; 95% CI 1.22–2.65, respectively), whereas high GI carbohydrate and high GL were associated with increased risk of proximal colon cancer (HR 1.94; 95% CI 1.18–3.16, HR 2.01; 95% CI 1.08–3.74, respectively). After stratification for waist‐to‐hip ratio (WHR), cancer was significantly associated with GI, and high GI carbohydrate, in those with high WHR. These findings suggest that high dietary GI and high carbohydrate intake from high GI foods are associated with increased risk of colorectal cancer.
What's new?
Diets rich in carbohydrate trigger increases in blood glucose and insulin levels, events that may be involved in the etiology of colorectal cancer. But carbohydrates vary in their impact on blood glucose levels, reflected in their glycemic index (GI) values, and whether high GI carbohydrates raise cancer risk remains much debated. Here, high dietary GI and elevated intake of carbohydrates from high GI foods were associated with increased risk of colorectal cancer. A diet rich in low GI carbohydrates, by contrast, was associated with a reduced risk of disease.

Evidence on associations between self-reported diabetes mellitus, diabetes duration, age at diabetes diagnosis, insulin treatment, and risk of biliary tract cancer (BTC) and hepatocellular carcinoma ...(HCC), independent of general and abdominal obesity is scarce.
We conducted a prospective analysis in the EPIC-cohort study among 363 426 participants with self-reported diabetes data. Multivariable adjusted relative risks and 95% confidence intervals were estimated from Cox regression models. In a nested case–control subset, analyses were carried out in HCV/HBV-negative individuals.
During 8.5 years of follow-up, 204 BTC cases including 75 gallbladder cancer (GBC) cases, and 176 HCC cases were identified. Independent of body mass index and waist-to-height ratio diabetes status was associated with higher risk of BTC and HCC 1.77 (1.00–3.13) and 2.17 (1.36–3.47). For BTC, the risk seemed to be higher in participants with shorter diabetes duration and those not treated with insulin. Regarding cancer subsites, diabetes was only associated with GBC 2.72 (1.17–6.31). The risk for HCC was particularly higher in participants treated with insulin. The results were not appreciably different in HCV/HBV-negative individuals.
This study supports the hypothesis that diabetes is a risk factor for BTC (particularly GBC) and HCC. Further research is required to establish whether diabetes treatment or duration is associated with these cancers.

Diet may impact important risk factors for endometrial cancer such as obesity and inflammation. However, evidence on the role of specific dietary factors is limited. We investigated associations ...between dietary fatty acids and endometrial cancer risk in the European Prospective Investigation into Cancer and Nutrition (EPIC).
This analysis includes 1,886 incident endometrial cancer cases and 297,432 non-cases. All participants were followed up for a mean of 8.8 years. Multivariable Cox proportional hazard models were used to estimate hazard ratios (HR) and 95% confidence intervals (CI) of endometrial cancer across quintiles of individual fatty acids estimated from various food sources quantified through food frequency questionnaires in the entire EPIC cohort. The false discovery rate (q-values) was computed to control for multiple comparisons.
Consumption of n-6 γ-linolenic acid was inversely associated with endometrial cancer risk (HR comparing 5th with 1st quintile
=0.77, 95% CI = 0.64; 0.92, p
=0.01, q-value = 0.15). This association was mainly driven by γ-linolenic acid derived from plant sources (HR
=0.94, 95%CI= (0.90;0.98), p = 0.01) but not from animal sources (HR
= 1.00, 95%CI = (0.92; 1.07), p = 0.92). In addition, an inverse association was found between consumption of n-3 α-linolenic acid from vegetable sources and endometrial cancer risk (HR
= 0.93, 95%CI = (0.87; 0.99), p = 0.04). No significant association was found between any other fatty acids (individual or grouped) and endometrial cancer risk.
Our results suggest that higher consumption of γ-linolenic acid and α-linoleic acid from plant sources may be associated with lower risk of endometrial cancer.

Summary
Prevention of hip fractures is of critical public health importance. In a cohort of adults from eight European countries, evidence was found that increased adherence to Mediterranean diet, ...measured by a 10-unit dietary score, is associated with reduced hip fracture incidence, particularly among men.
Introduction
Evidence on the role of dietary patterns on hip fracture incidence is scarce. We explored the association of adherence to Mediterranean diet (MD) with hip fracture incidence in a cohort from eight European countries.
Methods
A total of 188,795 eligible participants (48,814 men and 139,981 women) in the European Prospective Investigation into Cancer and nutrition study with mean age 48.6 years (±10.8) were followed for a median of 9 years, and 802 incident hip fractures were recorded. Diet was assessed at baseline through validated dietary instruments. Adherence to MD was evaluated by a MD score (MDs), on a 10-point scale, in which monounsaturated were substituted with unsaturated lipids. Association with hip fracture incidence was assessed through Cox regression with adjustment for potential confounders.
Results
Increased adherence to MD was associated with a 7 % decrease in hip fracture incidence hazard ratio (HR) per 1-unit increase in the MDs 0.93; 95 % confidence interval (95 % CI) = 0.89–0.98. This association was more evident among men and somewhat stronger among older individuals. Using increments close to one standard deviation of daily intake, in the overall sample, high vegetable (HR = 0.86; 95 % CI = 0.79–0.94) and high fruit (HR = 0.89; 95 % CI = 0.82–0.97) intake was associated with decreased hip fracture incidence, whereas high meat intake (HR = 1.18; 95 % CI = 1.06–1.31) with increased incidence. Excessive ethanol consumption (HR high versus moderate = 1.74; 95 % CI = 1.32–2.31) was also a risk factor.
Conclusions
In a prospective study of adults, increased adherence to MD appears to protect against hip fracture occurrence, particularly among men.
