Survival calculations

      I wonder if there might be a mistake regarding the number of survivors in the article by Dr Ferrone et al concerning pancreatic resection.

      Pancreatic ductal adenocarcinoma: long-term survival does not equal cure.
      Their paper covers the years 1985 to 2010 at Massachusetts General Hospital (MGH), and they claim an actual 19% survival rate, or 95 survivors of 499 resected patients, but show a Kaplan-Meier actuarial curve of 19% at 5 years.

          Pancreatic ductal adenocarcinoma represents 90% of pancreatic cancers and is an important cause of cancer death in the United States. Operative resection remains as the only treatment providing prolonged survival, but even after a curative resection, 5-year survival rates are low. Our aim was to identify the prognostic factors for long-term survival after resection of pancreatic ductal adenocarcinoma related to patients, treatments, and tumor biology.

          I am afraid I made a serious oversight in my first Letter to the Editors (Surgery 2013;154:645) regarding the paper by Ferrone et al,1 but it is mainly serious for the authors. In my bewilderment when I saw their figures, I stated in the letter that their study ended in 2010.
