Abstract
BACKGROUND: Resections for pancreatic ductal adenocarcinoma have now been carried out systematically for over 70 years. However, opinions still differ as to the results. Some consider it unresectable, whereas others claim a high survival percentage and recommend resections. METHODS: The literature on this surgery has been scrutinized from the onset, and 790 studies have been found that deal with resections and reveal survival information. RESULTS: Review reveals that the percentage of survivals is exaggerated with life-table methods when there is censoring of the data. Duplication of reporting survivors is rampant. CONCLUSION: After adjusting for calculations and duplications, the total number of 5-year survivors can hardly be more than 700-800.
