Blood selenium levels in nasopharyngeal cancer patients in south China.
Blood selenium concentrations in 111 nasopharyngeal cancer patients and 56 normal subjects were determined using a modified 2,3-diamino naphthalene fluorometric method. Cancer subjects in this study were divided into two groups and blood Se levels (mean +/- SD) were 0.105 +/- 0.024 for untreated cases, 0.113 +/- 0.034 for those who had received treatment, and 0.109 +/- 0.030 microgram/ml for all subjects. The results suggest that low blood Se levels in nasopharyngeal cancer patients are a consequence of their disease rather than the cause of the cancer.
