MedPage, Jan. 10, 2007 Patients who live at least five years after a pancreaticoduodenectomy for periampullary adenocarcinoma have a better than 50-50 chance of living another five years, according to a study in Baltimore. In fact, 65 percent of five-year survivors went on to live at least 10 years or more, a John Hopkins team headed by Taylor S. Riall, M.D., reported in Surgery. Dr. Riall is now at the University of Texas Medical Branch. For comparison, the five year survival rate of age-matched controls from the U.S. population was 87 percent, Dr. Riall and colleagues pointed out.
