摘要:
Inherited pancreatic cancers represent approximately 5-10% of all pancreatic cancers. Pancreatic cancer may be inherited as part of a known cancer syndrome or in association with hereditary pancreatitis or cystic fibrosis. However, most inherited pancreatic cancers do not occur in the context of a known syndrome, and these are referred to as familial pancreatic cancers. Growing evidence suggests the presence of a single autosomal dominant gene in familial pancreatic cancer kindreds, and a susceptibility locus on chromosome 4 has recently been identified in one such family. Pancreatic cancer is believed to arise from pancreatic dysplasia, and familial pancreatic cancer kindreds represent a particularly high-risk population for whom effective screening strategies are needed. One promising strategy has used endoscopic ultrasound to detected pancreatic dysplasia in members of familial pancreatic cancer kindreds.
