Abstract

Cancer of the pancreas remains one of the deadliest cancer types. Based on the GLOBOCAN 2012 estimates, pancreatic cancer causes more than 331000 deaths per year, ranking as the seventh leading cause of cancer death in both sexes together. Globally, about 338000 people had pancreatic cancer in 2012, making it the 11th most common cancer. The highest incidence and mortality rates of pancreatic cancer are found in developed countries. Trends for pancreatic cancer incidence and mortality varied considerably in the world. A known cause of pancreatic cancer is tobacco smoking. This risk factor is likely to explain some of the international variations and gender differences. The overall five-year survival rate is about 6% (ranges from 2% to 9%), but this vary very small between developed and developing countries. To date, the causes of pancreatic cancer are still insufficiently known, although certain risk factors have been identified, such as smoking, obesity, genetics, diabetes, diet, inactivity. There are no current screening recommendations for pancreatic cancer, so primary prevention is of utmost importance. A better understanding of the etiology and identifying the risk factors is essential for the primary prevention of this disease.

Keywords: Pancreatic cancer, Epidemiology, Incidence, Mortality, Trend, Risk factors

Core tip: Pancreatic cancer is the one of leading causes of cancer mortality and one of the most lethal malignant neoplasms across the world. The highest incidence and mortality rates of pancreatic cancer are found in developed countries. The estimated 5-year survival rate for pancreatic cancer is about 5%. The causes of pancreatic cancer are still insufficiently known, although certain risk factors have been identified, such as cigarette smoking, positive family history and genetics, diabetes mellitus, obesity, dietary factors, alcohol use, physical inactivity. There are no current screening recommendations for pancreatic cancer, so primary prevention is of utmost importance.
