Background: Scanty and inconsistent studies are available on the relation between dietary fiber intake and pancreatic cancer. A case–control study was carried out in northern Italy to further investigate the role of various types of dietary fibers in the etiology of pancreatic cancer.Patients and methods: Cases were 326 patients with incident pancreatic cancer, excluding neuroendocrine tumors, admitted to major teaching and general hospitals during 1991–2008. Controls were 652 patients admitted for acute, nonneoplastic conditions to the same hospital network of cases. Information was elicited using a validated food frequency questionnaire. Odds ratios (ORs) and the corresponding 95% confidence intervals (CIs) were estimated for intake quintiles of different types of fiber after allowance for total energy intake and other potential confounding factors.Results: Total fiber intake was inversely related to risk of pancreatic cancer (OR = 0.4 for highest versus lowest quintile of intake; 95% CI 0.2–0.7). An inverse association emerged between pancreatic cancer and both soluble (OR = 0.4; 95% CI 0.2–0.7) and total insoluble fiber (OR = 0.5; 95% CI 0.3–0.8), particularly cellulose (OR = 0.4; 95% CI 0.3–0.7) and lignin (OR = 0.5; 95% CI 0.3–0.9). Fruit fiber intake was inversely associated with pancreatic cancer (OR = 0.5; 95% CI 0.3–0.8), whereas grain fiber was not (OR = 1.2; 95% CI 0.7–2.0).Conclusions: This study suggests that selected types of fiber and total fiber are inversely related to pancreatic cancer.

AIM OF THE STUDY: We assessed the relation between metabolic syndrome (MetS) and its components and colorectal cancer. METHODS: We analysed data from a multicentre case-control study conducted in Italy and Switzerland, including 1378 cases of colon cancer, 878 cases of rectal cancer and 4661 controls. All cases were incident and histologically confirmed. Controls were subjects admitted to the same hospitals as cases with acute non-malignant conditions. MetS was defined according to the International Diabetes Federation criteria. Odds ratios (ORs) and the corresponding 95% confidence intervals (CIs) were estimated by multiple logistic regression models, including terms for major identified confounding factors for colorectal cancer. RESULTS: With reference to each component of the MetS, the ORs of colorectal cancer in men were 1.27 (95% CI, 0.95-1.69) for diabetes, 1.24 (95% CI, 1.03-1.48) for hypertension, 1.14 (95% CI, 0.93-1.40) for hypercholesterolaemia and 1.26 (95% CI, 1.08-1.48) for overweight at age 30. The corresponding ORs in women were 1.20 (95% CI, 0.82-1.75), 0.87 (95% CI, 0.71-1.06), 0.83 (95% CI, 0.66-1.03) and 1.06 (95% CI, 0.86-1.30). Colorectal cancer risk was increased in men (OR=1.86; 95% CI, 1.21-2.86), but not in women (OR=1.13; 95% CI, 0.66-1.93), with MetS. The ORs were 2.09 (95% CI, 1.38-3.18) in men and 1.15 (95% CI, 0.68-1.94) in women with > or =3 components of the MetS, as compared to no component. Results were similar for colon and rectal cancers. CONCLUSION: This study supports a direct association between MetS and both colon and rectal cancers in men, but not in women. [ABSTRACT FROM AUTHOR]

Background: We evaluated efficacy and safety of early and short-term prophylaxis with acenocumarine or dalteparin in the prevention of non-occlusive or occlusive central vein catheter-related thrombosis (CVCrT). [ABSTRACT FROM PUBLISHER]
