What is pancreatic cancer?

Pancreatic ductal adenocarcinoma is the most common form of pancreatic cancer, making up more than 80 percent of cases.1 It begins in the cells of the pancreas’s ducts, which transport juices containing important digestive enzymes into the small intestine.2

Pancreatic cancer is the fourth most common cause of global cancer-related deaths, and is almost always fatal.1 In 2012, it was estimated that around 44,000 new cases of pancreatic cancer were diagnosed and more than 37,000 deaths from this disease occurred in the United States alone, affecting both men and women.3 

Risk factors include having a family history of the disease itself or a history of chronic inflammation of the pancreas (pancreatitis). Other risk factors include having Lynch syndrome, diabetes, being overweight or obese, and smoking.3

Pancreatic cancer poses a particular challenge for The Cancer Genome Atlas (TCGA). All cancerous tumors are made up of a combination of normal and cancerous cells – and pancreatic cancer tumors have a relatively low percentage of cancerous cells. TCGA has strict requirements on only accepting samples of tumors with a high percentage of cancerous cells, as this allows for more accurate mutation detection. Because of the challenging nature of this disease, TCGA has relaxed its criteria regarding the percentage of cancerous cells to ensure samples received are representative of the disease.
