Epidemiological trends in pancreatic neoplasias.
Primary prevention is the most effective approach to reduce the incidence of pancreatic cancer. Epidemiological studies have contributed to the identification of risk factors for pancreatic cancer, suggesting an association with age, various medical conditions, environmental and lifestyle risk factors, and occupational and genetic conditions. Age is the strongest risk factor. The most consistently identified environmental risk factor is smoking, but there is less certainty concerning dietary factors. Studies have suggested a positive association with high energy intake, cholesterol and meat, while vegetable and fruit intakes are probably protective. Patients with chronic pancreatitis and new onset of diabetes mellitus have a low but increasing risk of having or developing pancreatic cancer. There is strong evidence for the association of hereditary pancreatitis or cystic diseases of the pancreas and pancreatic cancer. A family history of pancreatic cancer is an important risk factor, but only a small proportion can be linked with known familial cancer syndromes. Thus, additional yet unidentified predisposing risk factors have to be assumed.
