The Serum C-reactive Protein and Prooxidant-antioxidant Balance in Patients with Esophageal Cancer Compared to Healthy Subjects

摘要

Introduction: The molecular mechanisms involved in pathogenesis of esophageal cancer have been the main concern of several studies. In this study, we aimed to investigate the changes of serum prooxidant-antioxidant balance (PAB) value as a redox index, as well as serum C-reactive protein (CRP) compared to healthy control group. Materials and Methods: In a cross-sectional study, blood samples were drawn from 25 patients with esophageal cancer and 25 healthy subjects. Serum CRP and PAB value were measured in all samples according to relevant protocols. Results: Serum CRP was significantly higher in our patients (14.3 ± 3.2 mg/L) compared to healthy control group (4.6 ± 1.4 mg/L), with a p-value of less than 0.001. The value of PAB in our patients (133.9 ± 21.7) was also higher than that of healthy subject (51.3 ± 11.2), indicating a redox perturbation in favor of oxidants. Conclusion: There was a significant increase in both serum PAB value and CRP in patients with esophageal cancer compared to the control group, which indicated both oxidative stress and inflammatory response in patients with esophageal cancer, respectively.
