Plasma antioxidant vitamins in brain tumors.
Plasma levels of vitamins A, E and C were analyzed in 102 patients with different types of brain tumors. A follow-up study was done with 27 postoperative patients. On comparison with plasma from normal individuals, vitamin A and E were decreased, but the decrease was statistically insignificant. Vitamin C levels remained in the normal range. In a comparative study of preoperative and postoperative cases, plasma vitamin A levels in postoperative glioma patients were significantly higher than those in the pre-operative state. There was no significant difference in the plasma level of vitamins C and E. The results of the present study suggest that the plasma antioxidant vitamins are not altered effectively in brain tumor cases.
