In the last 20 years, an increasing interest toward oxidative stress has been documented in order to investigate their direct or indirect involvement in several mechanisms regarding oncogenesis and lymphomas in particular. The aim of this paper was to evaluate oxidative stress in dogs affected by malignant lymphoma in comparison to a control group, to investigate what factors can affect this status, and to point out similarities and differences with human. Forty-eight samples from four subjects, affected by high-grade centroblastic polymorphic lymphoma and receiving a standard chemotherapy, have been processed for derivatives of reactive oxygen metabolites (d-ROMs) and biological antioxidant potential (BAP) tests. The obtained data show a condition of oxidative stress in dogs with lymphoma, with a significant increase in reactive oxygen species (ROS) plasma levels and a decrease in antioxidant capacity.

Abstract

In the last 20 years, an increasing interest toward oxidative stress has been documented in order to investigate their direct or indirect involvement in several mechanisms regarding oncogenesis and lymphomas in particular. The aim of this paper was to evaluate oxidative stress in dogs affected by malignant lymphoma in comparison to a control group, to investigate what factors can affect this status, and to point out similarities and differences with human. Forty-eight samples from four subjects, affected by high-grade centroblastic polymorphic lymphoma and receiving a standard chemotherapy, have been processed for derivatives of reactive oxygen metabolites (d-ROMs) and biological antioxidant potential (BAP) tests. The obtained data show a condition of oxidative stress in dogs with lymphoma, with a significant increase in reactive oxygen species (ROS) plasma levels and a decrease in antioxidant capacity. No significant differences emerged on the basis of remission. Further results of canine studies about oxidative status in lymphomas could be a model for human, according to analogy between them.
