The median actuarial survival time for the entire group from the onset of symptoms was 70 months. Of the 28 known living patients, 8 had been followed for 12 years or more; the longest survivor has remained alive 289 months after the onset of symptoms. Eleven of the original 71 patients required no therapy; 5 remained alive 5 years or more.
