Survival of Laryngeal Cancer Patients Depending on Zinc Serum Level and Oxidative Stress Genotypes.

Stress contributes to various aspects of malignancy and could influence survival in laryngeal cancer patients. Among antioxidant mechanisms, zinc and the antioxidant enzymes superoxide dismutase 2, catalase and glutathione peroxidase 1 play a major role.
