Serum selenium and gastric cancer in two regions of Norfolk.
Selenium concentrations were measured in the serum of 244 patients attending the Norfolk and Norwich Hospital, and 246 attending the James Paget Hospital in Gorleston, Norfolk. Both the mean and the median serum selenium concentration was lower in Gorleston than in Norwich, the difference being much greater in women than in men. Whereas the selenium concentrations were normally distributed about the mean for the Norwich area, there was a skewed distribution for the Gorleston area. The results are discussed in relation to the previously observed high risk of intestinal type gastric cancer in the Gorleston area.
