title: Increase in free radical generation and lipid peroxidation following chemotherapy in patients with cancer.
abstract: Several anti-cancer drugs are known to bring about their tumoricidal actions by a free radical dependent mechanism. Majority of the studies reported that adriamycin, mitomycin C, bleomycin, etc., augment free radical generation and lipid peroxidation process in vitro. Our results reported here suggest that following chemotherapy both stimulated and unstimulated human polymorphonuclear leukocytes generate increased amounts of superoxide anion and hydrogen peroxide. This was accompanied by increased formation of lipid peroxidation products as measured by thiobarbituric acid assay. These results confirm that many anti-cancer drugs augment free radical generation and lipid peroxidation even in an vivo situation.
