Despite significant advancements in treatment, chemotherapy resistance and relapse remain major challenges to be overcome.

B-type acute lymphoblastic leukemia (B-ALL) is the most common childhood cancer. Despite significant advancements in treatment, chemotherapy resistance and relapse remain major challenges to be overcome. Oxidative stress markers, including lipoperoxides, have emerged as potential biomarkers in B-ALL patients under treatment. This study evaluated lipoperoxide levels in the peripheral blood of pediatric B-ALL patients during the induction phase of chemotherapy using high-sensitivity chemiluminescence and analyzed their association with clinical prognostic factors and patient outcomes, including definitive hospital discharge, disease relapse, and patient death. Lower lipoperoxide levels were observed in patients over 10 years old, those who achieved remission and were discharged from the hospital, and those with central nervous system (CNS) involvement. In contrast, significantly higher lipoperoxide levels were found in patients who relapsed, died, or had platelet counts exceeding 50,000/mm
3. Receiver operating characteristic (ROC) curve analysis suggests that lipoperoxides may serve as potential biomarkers during the induction phase of chemotherapy, distinguishing B-ALL patients undergoing treatment from those not in treatment (sensitivity: 92.31%; specificity: 71.43%). These findings highlight the potential utility of lipoperoxides as prognostic biomarkers in B-ALL patients.
