Background: Achieving first complete remission with induction chemotherapy (ICT) for acute myeloid leukemia (AML) correlates with patient’s prognosis. This study aimed to determine the correlation between oxidative stress and the outcome of ICT in AML patients.
Methods: A total of 195 AML patients underwent initial ICT at the Longyan First Affiliated Hospital of Fujian Medical University from 06-11-2018 to 12-30-2023. Three weeks after ICT, patients were divided into two groups, CR (complete remission) and PR (partial remission), by detecting blood parameters and bone marrow cells. Serum oxidative stress-related factors, malondialdehyde (MDA), superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), total antioxidant capacity (T-AOC), and growth/differentiation factor-15 (GDF15) activities or levels were measured to assess the diagnostic value of these factors as a means of diagnosing the efficacy of ICT in patients. Factors affecting PR after initial ICT were analyzed.
Results: Patients in the PR group had higher levels of oxidative stress three weeks after initial ICT. Compared with the CR group, patients in the PR group had elevated levels of MDA and GDF15 and reduced activities of SOD, GSH-Px, and T-AOC. Serum MDA levels (AUC 0.709; 95% CI. 0.618 - 0.781) and the combination of multiple indicators (AUC 0.791; 95% CI. 704 - 0.851) had diagnostic value for the efficacy of AML patients undergoing ICT. Serum MDA and GDF15 exceeding cutoff values were risk factors for PR in AML patients undergoing ICT, as were serum SOD and T-AOC below cutoff values. Preoperative malnutrition was associated with PR in patients.
Conclusions: Serum oxidative stress-related factors in AML patients are helpful in detecting the efficacy of ICT. Oxidative stress in response to ICT is useful for characterizing the efficacy in AML patients after ICT.
