Its systemic effects in DLBCL are unknown. Materials and Methods: This study included 53 patients with DLBCL, five patients with primary central nervous system lymphoma (PCNSL) and 20 healthy controls. The expression of Prx6 was evaluated immunohistochemically in DLBCL tissue samples and compared to its expression in blood serum. Results: Prx6 expression was the highest in healthy controls, followed by DLBCL patients and PCNSL patients. Febrile neutropenic infection after the first treatment course was associated with low pre-treatment Prx6 serum levels (<14 ng/ml) (p=0.025, OR=8.615, 95% confidence interval=1.032-71.933). Serum levels of Prx6 recovered after treatment (p=0.006). Conclusion: Patients with low Prx6 levels might be more prone to treatment-related adverse effects through elevated levels of oxidative stress.
