Surveillance for Pancreatic Cancer in Chronic Pancreatitis / 대한췌담도학회지

ABSTRACT

Pancreatic cancer can arise in the background of chronic pancreatitis (CP). The relative risks for pancreatic cancer in CP vary considerably according to other contributing factors such as disease duration, excess alcohol consumption, tobacco consumption, eating habits, physical activity, and late-onset diabetes. The incidence of pancreatic cancer is estimated to be about 10 per 105 per year, and the incidence and prevalence of CP are estimated to be 5-12 per 105 and 50 per 105 per year, respectively. The pooled relative risk estimates for pancreatic cancer in CP patients range from 2.7 to 13.3. Subsets of CP subjects with a family history of pancreatic cancer or those with newly developed diabetes over the age of 50 have a higher risk for pancreatic cancer. However, the prevalence of pancreatic cancer is not high enough to justify general screening of the adult CP population. Thus, it is necessary to select subsets of CP cohorts with a significantly high risk of pancreatic cancer. We need a better overall disease model that can define the interaction of multiple risk factors and their cumulative or potential effects on pancreatic cancer.
