title: Plasma selenium level in cancer patients.
abstract: Selenium has been shown to be a cancer preventive agent. A few studies have shown that increased selenium level is associated with decreased cancer incidence and decreased cancer mortality. The present study was carried out to find out the relationship of selenium level with site, extent of disease, recurrence of disease, histopathological diagnosis, anaemia and serum protein level of cancer patients. Plasma selenium level were studied in 100 patients and mean selenium level of 75.35 ng/ml in cancer patients was significantly less than control values (116.99 ng/ml) in normal healthy individuals (P < 0.003). The strongest association of plasma selenium level and cancer was found in cancer breast (70.50 ng/ml) and gastrointestinal tract (73.05 ng/ml) cancer. Selenium level decreased with the progress of disease and recurrence of disease. No significant association between histopathological diagnosis and selenium level was observed. Anaemia and hypoproteinemia was also not found to be related with selenium level.
