In 1975, we reported the remarkable case of a 42-year-old man with 
histologically proven widely disseminated reticulum cell sarcoma who, in a 
remarkably short time, appeared to enjoy not one, but two, complete spontaneous 
regressions of his fatal illness. Both these regressions coincided exactly in 
time with intravenous high-dose ascorbate administration, and it seemed 
reasonable to conclude that this unconventional therapy must have been 
responsible for his excellent responses. For those interested in spontaneous 
regressions of cancer and the possible mechanisms, we now report his subsequent 
progress some 17 years later.
