Relationship between the levels of oxidative stress in mesenteric and peripheral serum and clinicopathological variables in colorectal cancer

To explore the differences existing between the levels of oxidative stress in peripheral and mesenteric serum in patients with colorectal cancer. One hundred fifty patients with colorectal cancer who underwent surgery between May 2005 and March 2010 were prospectively analyzed. The differences between oxidative stress parameters in their peripheral and mesenteric blood were measured. The associations between peripheral and mesenteric levels and the staging and clinicopathological variables were investigated. Oxidative stress parameters were higher in patients with advanced tumor staging (p
