Background Experimental studies have linked exposure to tobacco-specific nitrosamines with pancreatic carcinogenesis. A number of epidemiological studies have examined the association between environmental tobacco smoke (ETS) and risk of pancreatic cancer but they have not yet been jointly summarised. Objectives To investigate the association between exposure to ETS and risk of pancreatic cancer by systematically reviewing and synthesising the available evidence. Methods We conducted a… 

Risk factors for pancreatic cancer: a summary review of meta-analytical studies.

About two-thirds of the major risk factors associated with PC are potentially modifiable, affording a unique opportunity for preventing one of the authors' deadliest cancers.

Active and passive smoking and risk of death from pancreatic cancer: findings from the Japan Collaborative Cohort Study.

Pancreatic Cancer Risk in Relation to Lifetime Smoking Patterns, Tobacco Type, and Dose–Response Relationships

Differences in pancreatic cancer risk by tobacco type and other habit characteristics, as well as nonlinear risk associations, are revealed.

The Health Effects of Passive Smoking: An Overview of Systematic Reviews Based on Observational Epidemiological Evidence

An overview of systematic reviews of observational epidemiological evidence suggests that passive smoking is significantly associated with an increasing risk of many diseases or health problems, especially diseases in children and cancers.

Occupational exposure to N-nitrosamines and pesticides and risk of pancreatic cancer

This comprehensive analysis of a large case–control study does not support an association between occupational exposure to N-nitrosamines or pesticide use and risk of pancreatic cancer.

Environmental Risk Factors of Pancreatic Cancer

This review summarizes the current evidence regarding the environmental (non-genetic, including lifestyle, and clinical factors) risk factors of pancreatic cancer and established risk factors are cigarette smoking, chronic diabetes, and obesity.

Using proton pump inhibitors increases the risk of hepato-biliary-pancreatic cancer. A systematic review and meta-analysis

The use of PPI may be associated with an increased risk of hepato-biliary-pancreatic cancer, and caution is needed when using PPIs among patients with a high risk of liver cancer.

The goal of this Review is to provide an up-to-date overview of the established modifiable and inherited risk factors for pancreatic cancer.

The Association Between Passive Smoking and Type 2 Diabetes

It is shown that passive smoking was significantly associated with an increased risk of type 2 diabetes in a random model and sensitivity analysis indicated that the overall results were reliable.



Environmental tobacco smoke and the risk of pancreatic cancer: findings from a Canadian population-based case-control study.

The results are suggestive of a weak association between pancreatic cancer and ETS, and suggest that ETS smoking exposures may confound the risk of pancreaticcancer associated with active smoking measures commonly used in epidemiologic studies.

Passive Smoking and Pancreatic Cancer in Women: a Prospective Cohort Study

The positive association with maternal smoking suggests that environmental tobacco smoke, potentially in utero or in early life, may be associated with pancreatic cancer.

Tobacco and the risk of pancreatic cancer: a review and meta-analysis

Based on estimates from four continents, smoking cigarettes causes a 75% increase in the risk of pancreatic cancer compared to non-smokers, and the risk persists for a minimum of 10 years after smoking cessation.

Cigarette smoking, environmental tobacco smoke exposure and pancreatic cancer risk in the European Prospective Investigation into Cancer and Nutrition

It is suggested that both active cigarette smoking, as well as exposure to ETS, is associated with increased risk of pancreatic cancer and that risk is reduced to levels of never smokers within 5 years of quitting.

Active and Passive Smoking and the Risk of Pancreatic Cancer in the Netherlands Cohort Study

It is confirmed that cigarette smoking is an important risk factor for pancreatic cancer, whereas quitting smoking reduced risk and approached unity after ≥20 years of quitting.

Passive smoking at home and cancer risk: a population-based prospective study in Japanese nonsmoking women

The results show that passive smoking may affect the risk of cancers other than lung cancer, and the risks of smoking-related cancers and breast cancer were materially unchanged.

Physical Activity and Pancreatic Cancer Risk: A Systematic Review

This systematic review does not provide strong evidence for an association between physical activity and risk for pancreatic cancer.

A tobacco-specific lung carcinogen in the urine of men exposed to cigarette smoke.

Nonsmokers exposed to sidestream cigarette smoke take up and metabolize a lung carcinogen, which provides experimental support for the proposal that environmental tobacco smoke can cause lung cancer.

Epidemiology of Pancreatic Cancer: An Update

It is estimated that 5–10% of patients with pancreatic cancer have an underlying germline disorder, and adopting a healthy lifestyle could substantially reduce Pancreatic cancer risk.
