Cancer of the pancreas: diagnostic accuracy and survival statistics.
We have reviewed the natural history, reliability of diagnosis, and survivorship of 100 patients with adenocarcinoma of the pancreas, in the context of a thorough review of the literature on survival after therapy for adenocarcinoma of the pancreas. There is 40--62.5% error in the histologic confirmation of the diagnosis of pancreatic cancer. The error by inspection and palpation alone at the time of surgery may be as great as 25%. The absolute 5 year survival rate calculated from 61 clinical studies representing approximately 15,000 patients is 0.4%. The best series in the current literature has only 3% 5 year rate based upon the total population of pancreatic cancer patients. 12.3% of 5 year survivors from the world literature did not have curative surgery. This study shows the necessity for standardization of reporting methods. The same patients and survivors should not be used repeatedly in different reports. Some authors who claim the most effective palliation by pancreatic resection have the highest mortality rates.
