title: Selenium levels in blood and plasma, and glutathione peroxidase activity in blood of breast cancer patients during adjuvant treatment with cyclophosphamide, methotrexate and 5-fluorouracil.
abstract: Glutathione peroxidase activity in whole blood and selenium levels in whole blood and plasma from breast cancer patients, were measured during combination chemotherapy with cyclophosphamide, methotrexate and 5-fluorouracil. No significant change in either glutathione peroxidase activity or selenium levels was observed. Comparison with matched controls showed no significant differences for either parameter.
