Pancreatic cancer is a difficult disease. Even for surgically resectable (and therefore potentially curable) tumors, the risk of cancer recurrence and subsequent death remains high. Consequently, the prognosis of pancreatic cancer usually ranges from fair to poor. Only about 20% of patients undergoing a Whipple procedure for potentially curable pancreatic cancer live five years, with the rest surviving on average less than two years. For patients with incurable (locally advanced unresectable or metastatic) pancreatic cancer, survival is even shorter; typically, it is measured in months. With metastatic disease (stage IV), the average survival is just over six months. The American Cancer Society statistics suggest that for all stages of pancreatic cancer combined, the one-year survival rate is 20% and the mortality rate is 80%, while the five-year survival rate is 6% with a mortality rate of 94%. These rates are mainly based on patients diagnosed between 1985 and 2004 and are representative of those patients according to the American Cancer Society (ACS). These data-based survival rates are what are available currently, but they are only estimates and are not predictive about what may happen to each individual. Currently, the ACS advises patients to discuss their individual situation and prognosis with their treatment team of physicians. Doctors around the world continue to study pancreatic cancer and strive to improve treatments, but progress has been difficult to achieve.
