Abstract

Oxidative stress serves an important role in carcinogenesis. The present study investigated the clinical significance of oxidative stress as a prognostic factor for diffuse large B‑cell lymphoma (DLBCL). The participants comprised 55 consecutive patients with DLBCL. A commercially available derivatives of reactive oxygen metabolites (d‑ROMs) test kit was used to assess oxidant levels. Similarly, a commercially available biological antioxidant potential (BAP) test was used to assess antioxidant levels. The antioxidative/oxidative stress ratio was calculated as d‑ROMs/BAP. The median serum concentration of d‑ROMs was 425 µM. The levels of d‑ROMs were significantly higher in patients with DLBCL than in healthy volunteers (P<0.01). The complete remission (CR) rates in patients with d‑ROMs <425 and ≥425 µM were 81.5 and 85.7%, respectively [not significant (NS)]. The 3‑year overall survival (OS) rates for patients with d‑ROMs <425 and ≥425 µM were 67.2 and 72.0%, respectively (NS). The median BAP was 2,002 µM. The CR rates of patients with BAP <2,002 and ≥2,002 µM were 77.8 and 88.9%, respectively (NS). The 3‑year OS rates of patients with BAP <2,002 and ≥2,002 µM were 60.9 and 75.9%, respectively (NS). No significant difference in the d‑ROMs/BAP ratio was observed between groups. Multivariate analysis revealed that d‑ROMs were an independent prognostic factor for progression-free survival.
