Can Breast Tumors Affect the Oxidative Status of the Surrounding Environment? A Comparative Analysis among Cancerous Breast, Mammary Adjacent Tissue, and Plasma

Table 2

Spearman’s correlations among the levels of oxidative parameters in plasma and plasma matched tumoral tissue.

Plasma versus tumor	value	value
TNF-α	0.8322
NO × nitrotyrosine	0.7771
Carbonyl content	0.7082
TRAP	−0.09790
Homocysteine	0.2562
MDA	0.5691
Anti-MPO	0.6598
Lipid peroxidation	0.5870
NO	0.5477

TNF- = tumor necrosis factor-alpha, TRAP = total antioxidant capacity, MDA = malondialdehyde, and MPO = myeloperoxidase.
