Abstract
In Italy, pancreatic cancer is the fifth leading cause of tumor related death with about 7000 new cases per year and a mortality rate of 95%. In a recent prospective epidemiological study on the Italian population, a family history was found in about 10% of patients suffering from a ductal adenocarcinoma of the pancreas (PDAC). A position paper from the Italian Registry for Familial Pancreatic Cancer was made to manage these high-risk individuals. Even though in the majority of high-risk individuals a genetic test to identify familial predisposition is not available, a screening protocol seems to be reasonable for subjects who have a >10-fold greater risk for the development of PDAC. However this kind of screening should be included in clinical trials, performed in centers with high expertise in pancreatic disease, using the least aggressive diagnostic modalities.

Abstract
The literature has consistently reported no association between low to moderate alcohol consumption and pancreatic cancer; however, a few studies have shown that high levels of intake may increase risk. Most single studies have limited power to detect associations even in the highest alcohol intake categories or to examine associations by alcohol type. We analyzed these associations using 1,530 pancreatic cancer cases and 1,530 controls from the Pancreatic Cancer Cohort Consortium (PanScan) nested case-control study. Odds ratios (OR) and 95% confidence intervals (95% CI) were calculated using unconditional logistic regression, adjusting for potential confounders. We observed no significant overall association between total alcohol (ethanol) intake and pancreatic cancer risk (OR = 1.38, 95% CI = 0.86-2.23, for 60 or more g/day vs. >0 to <5 g/day). A statistically significant increase in risk was observed among men consuming 45 or more grams of alcohol from liquor per day (OR = 2.23, 95% CI = 1.02-4.87, compared to 0 g/day of alcohol from liquor, P-trend = 0.12), but not among women (OR = 1.35, 95% CI = 0.63-2.87, for 30 or more g/day of alcohol from liquor, compared to none). No associations were noted for wine or beer intake. Overall, no significant increase in risk was observed, but a small effect among heavy drinkers cannot be ruled out.

Abstract
BACKGROUND/AIMS An association between past history of hepatitis B virus (HBV) infection and pancreatic cancer (PC) has recently been reported. We investigated whether HBV and hepatitis C virus (HCV) infections are associated with the development of PC in Korea. METHODS We retrospectively recruited patients with PC and sex- and, age-matched control patients with stomach cancer (SC) during the previous 5 years. Serum HBsAg and anti-HCV were examined, and data on smoking, alcohol intake, diabetes, and the history of chronic pancreatitis (CP) were collected. RESULTS A total of 506 PC and 1008 SC were enrolled, with respectively 58.1% and 97.3% of these cases being confirmed histologically. The mean age and sex ratio (male:female) were 63.5 years and 1.5:1 in the PC patients and 63.9 years and 1.5:1 in the SC patients respectively (P>0.05). The odds ratios (95% confidence interval, 95% CI) in univariate analysis were 0.90 (0.52-1.56; P=0.70) for HBsAg, 1.87 (0.87-4.01; P=0.11) for anti-HCV, 2.66 (2.04-3.48; P<0.001) for the presence of diabetes, 2.30 (1.83-2.90; P<0.001) for smoking, 1.14 (0.89-1.46; P=0.31) for alcohol intake, and 4.40 (1.66-11.66; P=0.003) for the history of CP. Independent risk factors for PC were presence of diabetes (OR, 2.67; 95% CI, 2.00-3.56; P<0.001), smoking (OR, 2.49; 95% CI, 1.93-3.21; P<0.001) and history of CP (OR, 4.60; 95% CI, 1.56-13.53; P=0.006). CONCLUSIONS There was no significant association between seropositivity for HBsAg or anti-HCV and PC. Further studies are warranted to clarify the association between HBV infection and PC in regions where HBV is endemic.

Body mass index, effect modifiers, and risk of pancreatic cancer: a pooled study of seven prospective cohorts. Cancer Causes Control 2010; 21:1305-14. [PMID: 20383573 DOI: 10.1007/s10552-010-9558-x] [Citation(s) in RCA: 74] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/10/2009] [Accepted: 03/26/2010] [Indexed: 01/02/2023]
Abstract
OBJECTIVE To investigate whether the positive association of body mass index (BMI, kg/m(2)) with risk of pancreatic cancer is modified by age, sex, smoking status, physical activity, and history of diabetes. METHODS In a pooled analysis of primary data of seven prospective cohorts including 458,070 men and 485,689 women, we identified 2,454 patients with incident pancreatic cancer during an average 6.9 years of follow-up. Cox proportional hazard regression models were used in data analysis. RESULTS In a random-effects meta-analysis, for every 5 kg/m(2) increment in BMI, the summary relative risk (RR) was 1.06 (95% confidence interval (CI) 0.99-1.13) for men and 1.12 (95% CI 1.05-1.19) for women. The aggregate analysis showed that compared with normal weight (BMI: 18.5 to <25), the adjusted RR was 1.13 (95% CI 1.03-1.23) for overweight (BMI: 25 to <30) and 1.19 (95% CI 1.05-1.35) for obesity class I (BMI: 30 to <35). Tests of interactions of BMI effects by other risk factors were not statistically significant. Every 5 kg/m(2) increment in BMI was associated with an increased risk of pancreatic cancer among never and former smokers, but not among current smokers (P-interaction = 0.08). CONCLUSION The present evidence suggests that a high BMI is an independent risk factor of pancreatic cancer.

Abstract
Alcohol consumption is postulated to be a risk factor for pancreatic cancer (PCA), but clarification of degree of risk related to consumption characteristics is lacking. We examined the association between alcohol consumption and PCA in a population-based case-control study (532 cases, 1,701 controls) in the San Francisco Bay Area. Population-based controls were frequency-matched by sex, age within 5-year categories and county of residence to cases identified by the cancer registry's rapid case ascertainment. Detailed alcohol consumption data, including binge drinking (>or=5 drinks/day), were collected during in-person interviews. Odds ratios (OR) and 95% confidence intervals (95% CI) were computed using adjusted unconditional logistic regression. Depending on dose, duration, and pattern of drinking, ORs were increased 1.5- to 6-fold among men but not women. In men, ORs increased with increasing overall alcohol consumption (22-35 drinks/week OR = 2.2, 95% CI = 1.1-4.0; >or=35 drinks/week OR = 2.6, 95% CI = 1.3-5.1, p-trend = 0.04). Most notable were effects with a history of binge drinking (OR = 3.5, 95% CI = 1.6-7.5) including increased number of drinks per day (p-trend = 0.002), and increased years of binge drinking (p-trend = 0.0006). In fully adjusted models that included smoking and other confounders, ORs for binge drinking in men were somewhat higher than in age-adjusted models. Results from our detailed analyses provide support for heavy alcohol consumption (including binge drinking) as a risk factor for PCA in men.

Abstract
Each year about 13,000 patients are diagnosed with pancreatic cancer in Germany. More than 95% of all pancreatic cancers are ductal adenocarcinomas and originate from malignant transformation of the exocrine pancreas. There is good evidence that ductal pancreatic cancer develops from so-called PanIn lesions of the ductal epithelium (for pancreatic intraepithelial neoplasia). Males and females are affected at a similar rate. In the German cancer registry, ductal pancreatic cancer incidence is ninth in males and seventh in females. Ductal pancreatic cancer is mostly diagnosed at a late stage. This is due to a lack of early symptoms. The tumor is rather refractory to chemo- or radiotherapy. Only R0 resection of the tumor bears a chance of cure. The unfavorable prognosis of ductal pancreatic cancer is reflected by the fact that pancreatic cancer is the fifth leading cause of cancer death and 5-year survival is only 4%. To assess the current evidence in our understanding of carcinogenesis, diagnosis and treatment of pancreatic cancer, the interdiciplinary S3 guideline "Exocrine pancreatic cancer" was established and published in 2007. The aim of this guideline is to improve early diagnosis of pancreatic cancer, to achieve a higher rate of curative surgery, to prolong survival postoperatively as well as in the palliative setting, to assure a good quality of life, and to improve pain management and nutritional support in supportive care. In the following article the authors will highlight major points of the S3 guideline and point out important developments that have occurred after publication of the guideline.

Abstract
OBJECTIVES Pancreatic carcinoma etiology and molecular pathogenesis are weakly understood. Based on the assumption that genetic variation in carcinogen metabolism further modifies the risk of exposure-related cancers, we studied the association of polymorphisms in the tobacco carcinogen-metabolizing gene CYP2A13 (Arg101Stop) and the alcohol-metabolizing genes ADH1B (Arg48His) and ADH1C (Ile350Val) with pancreatic cancer risk. METHODS Polymorphisms were studied by allelic discrimination. RESULTS In a hospital-based case-control study, CYP2A13 variant alleles coding an inactive enzyme were found in 7 of 265 cancer-free controls and in none of 235 pancreatic carcinoma patients. Neither ADH1B or ADH1C polymorphisms alone nor their combinations showed a significant effect on pancreatic cancer risk. CONCLUSIONS The first study of the roles of CYP2A13, ADH1B, and ADH1C in pancreatic cancer etiology suggested that the controls may have a lower ability to bioactivate tobacco-derived procarcinogens than the cases.

Abstract
In order to provide a more precise quantification of the association between alcohol consumption and pancreatic cancer risk, we performed a meta-analysis of relevant dose-risk results. We conducted a PubMed search of all case-control (N=21) and cohort (N=11) studies published up to March 2009. We computed summary relative risk (RR) estimates using either fixed- or, in the presence of heterogeneity, random-effects models. The pooled RR was 0.92 (95% confidence interval, 95% CI, 0.86-0.97) for <3 drinks/day and 1.22 (95% CI, 1.12-1.34) for > or = 3 drinks/day. The increased risk for heavy drinking was similar in women and men, but apparently stronger in cohort studies (RR=1.29), in studies with high quality index (RR=1.30), and did not appear to be explained by residual confounding by either history of pancreatitis or tobacco smoking. This meta-analysis provides strong evidence for the absence of a role of moderate drinking in pancreatic carcinogenesis, coupled to an increased risk for heavy alcohol drinking. Given the moderate increase in risk and the low prevalence of heavy drinkers in most populations, alcohol appears to be responsible only for a small fraction of all pancreatic cancers.

Abstract
Pancreatic cancer, although infrequent, has an exceptionally high mortality rate, making it one of the four or five most common causes of cancer mortality in developed countries. The incidence of pancreatic cancer varies greatly across regions, which suggests roles for lifestyle factors, such as diet, or environmental factors, such as vitamin D exposure. Smoking is the most common known risk factor, and is the cause of 20-25% of all pancreatic tumors. Alcohol does not seem to be a risk factor, unless it leads to chronic pancreatitis, which is a probable risk factor. Long-standing diabetes increases the risk of pancreatic cancer, but can also be an early manifestation of pancreatic tumors. 5-10% of patients with pancreatic cancer have an underlying germline disorder, while the remaining percentage of cancer cases is thought to be caused by somatic mutations. Some individual studies suggest that mutations in various polymorphic genes can lead to small increases in the risk of pancreatic cancer, but these findings need to be replicated. Rising prevalence of smoking in developing countries, improved diagnosis and increasing population longevity are all likely to increase the global burden of pancreatic cancer in the coming decades.

Abstract
In Italy, pancreatic cancer accounts for approximately 5% of cancer-related deaths. Tobacco smoking is the major established risk factor for this cancer, whereas the role of alcohol consumption is open to debate. Between 1991 and 2008, we conducted a hospital-based case-control study on pancreatic cancer in northern Italy. Cases were 326 patients (median age 63 years) with incident pancreatic cancer admitted to major general hospitals. Controls were 652 patients (median age 63 years) with acute non-neoplastic conditions admitted to the same hospital network of cases. Multiple logistic regression was used to estimate the odds ratios (OR) and the corresponding 95% confidence intervals (CI). Pancreatic cancer was associated to current smoking (OR=1.68; 95% CI: 1.13-2.48), and the risk rose with increasing number of cigarettes/day (OR=2.04; 95% CI: 1.14-3.66 for > or = 20 cigarettes/day). No association emerged for former smokers (OR=0.98; 95% CI: 0.66-1.45). Alcohol consumption was associated to increased pancreatic cancer risk, but ORs were significant only among heavy drinkers (ORs: 2.03 and 3.42 for 21-34 and > or = 35 drinks/week, respectively). Pancreatic cancer risk was 4.3-fold higher in heavy smokers (> or = 20 cigarettes/day) and heavy drinkers (> or = 21 drinks/week) in comparison with never smokers who drunk < 7 drinks/week, which is compatible with an additive effect of these exposures. In conclusion, we found that tobacco smoking and alcohol drinking are two independent risk factors for pancreatic cancer which may be responsible for approximately one third of these cancers in our population.
