Liver cancer is the sixth most common cancer and the second leading cause of death globally. The 5-year survival rate is very low (5%) because very often the disease is diagnosed when already in an advanced stage. The incidence varies according to the geographical area (it is more widespread in Asia than in Europe). In Italy it is rarer and represents 3% of all new diagnoses of cancer with a 2:1 men to women ratio (13,000 cases reported in 2017).
It is a disease in which pancreatic cells grow and multiply in an uncontrolled manner. The majority of pancreatic cancers (approximately 70%) originates in the exocrine pancreas and is called pancreatic adenocarcinomas.
