Azeem, K / Horáková, D / Tomaskova, H / Procházka, V / Shonová, O / Martínek, A / Kysely, Z / Janout, V / Kollárová, H. · ·Klin Onkol · Pubmed #27296404.

ABSTRACT: BACKGROUND: Pancreatic cancer is serious and rapidly progressing condition. Little is known about the role of diet in etiology of pancreatic cancer. The study focused on the role of selected dietary factors related to pancreatic cancer. MATERIAL AND METHODS: The case-control study was performed in the Czech Republic in 2006- 2009, involving three centers in Olomouc, Ostrava and Ceske Budejovice. It comprised a total of 530 persons, of whom 310 had pancreatic cancer and 220 were controls. Data were obtained directly from each participant in an interview with a trained interviewer and entered into a standardized questionnaire. The data were analyzed using a crude odds ratio (OR) and multivariate logistic regression with an adjusted OR and 95% CI. The statistical analysis was performed with the STATA v. 10 software. RESULTS: A very strong protective effect was found in pickled cabbage (OR 0.32; 95% CI 0.19- 0.55), broccoli (OR 0.37; 95% CI 0.25- 0.53), cooked onion (OR 0.14; 95% CI 0.08- 0.27), tomatoes (OR 0.28; 95% CI 0.13- 0.60), raw carrot (OR 0.33; 95% CI 0.20- 0.56), cooked carrot (OR 0.35; 95% CI 0.19- 0.62). In logistic regression model, statistically significant protective associations were found in consumption of more than three portions of cooked vegetables per week (OR 0.16; 95% CI 0.05- 0.55) and high consumption of citrus fruit (OR 0.46; 95% CI 0.23- 0.90). CONCLUSION: The study found statistically significant protective effect of consumption of more than three portions of cooked vegetables per week and high consumption of citrus fruit.

2 Article [A multifactor epidemiological analysis of risk factors for pancreatic cancer in women]. 2015

Azeem, K / Horáková, D / Tomášková, H / Ševčíková, J / Vlčková, J / Pastucha, D / Procházka, V / Shonová, O / Martínek, A / Janout, V / Žídková, V / Kollárová, H. · ·Epidemiol Mikrobiol Imunol · Pubmed #25872994.

ABSTRACT: STUDY OBJECTIVE: A multifactor analysis of risk factors for pancreas cancer in women. MATERIAL AND METHODS: A case-control study was conducted in three centres in the Czech Republic (Olomouc, Ostrava, and České Budějovice) in 2006-2009. In total, 226 women (129 pancreas cancer cases, 97 controls) were included in the study. Statistical analysis was performed, the crude odds ratio (OR) was calculated, and logistic regression analysis was used at a 5% level of statistical significance. RESULTS: A statistically significant inverse association was found between pancreatic cancer and oral contraceptives (OR 0.21; 95% CI: 0.07-0.69). Pregnancy and number of pregnancies or gynecological surgical procedures did not show any association with pancreatic cancer. No significant difference in the first menstrual period was found between pancreatic cancer patients and controls. CONCLUSIONS: The study results showed inverse association between pancreatic cancer and oral contraceptives (OR 0.21; 95% CI: 0.07-0.69), controlled alcohol consumption (OR 0.26; 95% CI: 0.12-0.55), and anti-inflamatory drug use (OR 0.10; 95% CI: 0.02-0.41).

3 Article Is physical activity a protective factor against pancreatic cancer? 2014

Kollarova, H / Azeem, K / Tomaskova, H / Horakova, D / Prochazka, V / Martinek, A / Shonova, O / Sevcikova, J / Sevcikova, V / Janout, V. · ·Bratisl Lek Listy · Pubmed #25246281.

ABSTRACT: OBJECTIVES: The objective of the study was to analyze an association between selected factors and pancreatic cancer, assuming that knowing the etiology would help influence the incidence of this severe type of cancer through primary prevention. In addition to age, gender, BMI and education, the analysis aimed at assessing occupational and leisure-time physical activities with respect to pancreatic cancer. BACKGROUND: In numerous studies, physical activity is reported to be a protective factor against pancreatic cancer. METHODS: A case-control study was carried out in three centers in the Czech Republic in 2006-2009. RESULTS: The study comprised a total of 529 individuals, of which 309 were patients with pancreatic cancer and 220 were controls. Leisure-time physical activity showed a statistically significant inverse association with a crude odds ratio of 0.65 (95% CI 0.45-0.93), even after adjustment for other studied factors (OR =0.63, 95% CI 0.43-0.92). Conversely, for occupational physical activity, a positive association was only suggested. CONCLUSIONS: Leisure-time physical activity is a protective factor against the development of pancreatic cancer. Occupational physical activity was not confirmed as a protective factor against pancreatic cancer (Tab. 4, Fig. 1, Ref. 22).

ABSTRACT: PURPOSE: Findings from epidemiological studies examining physical activity in relation to pancreatic cancer risk have suggested decreased risks for physical activity; however, the results are inconsistent. METHODS: The association between occupational and leisure-time physical activity and risk of pancreatic cancer was examined among 826 pancreatic cancer cases and 930 age-, sex- and center-matched controls from a large multicenter central European study in Czech Republic and Slovakia recruited between 2004 and 2012. Data on physical activity including type and dose (frequency, intensity, and duration) were examined using multivariable-adjusted logistic regression models. RESULTS: Occupational physical activity was not significantly associated with risk of pancreatic cancer [odds ratio (OR) 0.90, 95 % confidence interval (CI) 0.71-1.15]. A 35 % decrease in risk of pancreatic cancer was observed for regular leisure-time physical activity (OR 0.65, 95 % CI 0.52-0.87). The risk estimates were significant for low and moderate intensity of activity with the strongest protective effect among individuals who exercised during more than 40 weeks per year. The results for cumulated leisure-time physical activity assessed 1 year prior to diagnosis achieved the same level of risk reduction. In addition, stronger risk estimates for leisure-time physical activity were observed among women (men: OR 0.74, 95 % CI 0.54-1.01; women: OR 0.53, 95 % CI 0.37-0.75). The findings for female participants were stronger for intensity and frequency of leisure-time physical activity, in particular for light and moderate activity (OR 0.43, 95 % CI 0.25-0.75; and OR 0.57, 95 % CI 0.37-0.88, respectively). CONCLUSION: These results provide evidence for a decreased risk of pancreatic cancer associated with regular leisure-time physical activity.

5 Article [Pancreatic cancer and lifestyle factors]. 2013

Azeem, K / Sevčíková, J / Tomášková, H / Horáková, D / Procházka, V / Martínek, A / Shonová, O / Janout, V / Kollárová, H. ·Ústav preventivního lékařství, LF UP v Olomouci. ·Klin Onkol · Pubmed #23961856.

ABSTRACT: BACKGROUND: Pancreatic cancer is a serious cancer with unfavorable prognosis. Due to differences in the incidence of pancreatic cancer in different regions, it is clear that factors associated with lifestyle play an important role in the etiology. The aim of this study was to evaluate the impact of selected lifestyle factors in relation to pancreatic cancer. MATERIALS AND METHODS: The study included a total of 529 subjects, including 309 cases and 220 control subjects. Cases of newly diagnosed patients with pancreatic cancer who lived in the region were selected in hospitals in three centers (University Hospital Olomouc, University Hospital Ostrava, Hospital Ceske Budejovice). The control group was obtained in cooperation with selected general practitioners for adults, and it is a population control group. RESULTS: Analyses compared persons who reported consuming alcohol with those who do not consume alcohol. Results showed a statistically significant inverse association, even after adjustment for the other studied factors (OR = 0.57, 95% CI 0.36 to 0.89). When assessing leisure time physical activity, results showed statistically significant inverse association and 35% decrease in the risk (crude OR = 0.65, 95% CI 0.45 to 0.93), and this inverse association was confirmed after adjustment for other studied factors although the result is on the border of statistical significance (adjusted OR = 0.68, 95% CI 0.44 to 1.04). Drinking coffee and tea has only a marginal impact on the occurrence of pancreatic cancer, although the medium and high consumption of black tea was found increased risk by 90 or 44%, respectively. Smoking is considered a causal risk factor for pancreatic cancer, but in this study, a positive association was not found. The study found no statistically significant association between overweight and obesity. CONCLUSION: Physical activity, dietary measures that will lead to weight loss and education to non-smoking can have a significant impact on the primary prevention of cancer.

6 Article Body mass index and body size in early adulthood and risk of pancreatic cancer in a central European multicenter case-control study. 2011

Urayama, Kevin Y / Holcatova, Ivana / Janout, Vladimir / Foretova, Lenka / Fabianova, Eleonora / Adamcakova, Zora / Ryska, Miroslav / Martinek, Arnost / Shonova, Olga / Brennan, Paul / Scélo, Ghislaine. ·International Agency for Research on Cancer, Lyon, France. ·Int J Cancer · Pubmed #21520034.

ABSTRACT: The relationship between two measures of excess body weight, body mass index (BMI) and body size score, and risk of pancreatic cancer was examined among 574 pancreatic cancer cases and 596 frequency-matched controls from the Czech Republic and Slovakia enrolled between 2004 and 2009. Analyses using multivariable logistic regression showed an increased risk of pancreatic cancer associated with elevated quartiles of BMI at ages 20 [fourth quartile: odds ratio (OR) = 1.79, 95% confidence interval (CI): 1.23, 2.61] and 40 (fourth quartile: OR = 1.57, 95% CI: 1.09, 2.27) compared to the lowest quartile. Consistent results were observed for body size score at ages 20 (high versus low: OR = 1.66, 95% CI: 1.08, 2.57) and 40 (medium versus low: OR = 1.36, 95% CI: 1.00, 1.86), but no association was found for BMI and body size score at 2 years before the interview. Stronger risk estimates for BMI were observed in males than females, particularly at age 20, but the analysis of body size yielded similar estimates by sex. When considering excess body weight at both ages 20 and 40 jointly, the highest risk estimates were observed among subjects with elevated levels at both time periods in the analysis of BMI (OR = 1.86, 95% CI: 1.32, 2.62) and body size (OR = 1.53, 95% CI: 1.09, 2.13). These findings, based on two different measures, provide strong support for an increased risk of pancreatic cancer associated with excess body weight, possibly strongest during early adulthood.
