Assessment of oxidative stress in acute myeloid leukemia
"nBackground: Many chemotherapeutic regimens used in the treatment of cancer generate free radicals that may be a part of their beneficial effects. The aim of this study was to assess the oxidative status in patients undergoing chemotherapy for acute myeloid leukemia (AML)."n &...
