E.Tsimoyiannis, G. Hatzikosta General Hospital

Brief Summary:
Study of Oxidative stress Markers (F2 Isoprostanes for lipid peroxidation, Carbonyl groups for protein peroxidation, 3 Nitrotyrosine for damage by nitrogens, and 8-Hydroxyguanosine for RNA peroxidation)in patients with colorectal cancer undergo surgical treatment (preoperatively during the intervention and postoperatively) and controls.

Condition or disease Intervention/treatment Phase
Colorectal Cancer Colon Rectal Resection Oxidative Stress Procedure: Surgery for colorectal cancer Not Applicable

Detailed Description:
Study of the impact of surgery on Lipid peroxidation, Protein peroxidation, damage by nitrogens, and RNA peroxidation, in patients undergo surgical resection for colorectal cancer and compared with controls, and validation of the responsiveness of oxidative stress markers on surgery
