Pancreatic cancer - Wikipedia, the free encyclopedia
Pancreatic cancer is a malignant neoplasm of the pancreas. Each year in the United States, about 42,470 individuals are diagnosed with this condition and 35,240 die from the disease.[1] The prognosis is relatively poor but has improved; the three-year survival rate is now about thirty percent, but less than 5 percent of those diagnosed are still alive five years after diagnosis. Complete remission is still rather rare.[2]
About 95% of exocrine pancreatic cancers are adenocarcinomas (M8140/3). The remaining 5% include adenosquamous carcinomas, signet ring cell carcinomas, hepatoid carcinomas, colloid carcinomas, undifferentiated carcinomas, and undifferentiated carcinomas with osteoclast-like giant cells.[3] Exocrine pancreatic cancers are far more common than endocrine pancreatic cancers (also known as islet cell carcinomas), which make up about 1% of total cases.[4][5]
