Objective:
To measure plasma concentrations of alpha-tocopherol and urate to determine whether there is any relationship with different types of cancer before treatment.
Method:
Plasma concentrations of those two antioxidants were measured in cancer patients and sex- and age-matched controls. Plasma total cholesterol concentration was measured to derive an alpha-tocopherol/cholesterol ratio.
Results:
Alpha-tocopherol and urate concentrations as well as alpha-tocopherol/cholesterol ratios were significantly lower in the cancer patients as whole, in gastrointestinal cancer and in breast cancer compared to the controls. There was no significant relationship between alpha-tocopherol and urate levels in either the plasma of patients (r=0.048; P=0.653) or controls (r=0.073; P=0.406). Alpha-tocopherol was more positively correlated with cholesterol in the plasma of controls (r=0.539; P < 0.0001) in comparison with the patients (r=0.456; P < 0.0001). There was no significant correlation between urate and cholesterol levels in both patient and control plasma samples.
Conclusion:
The data suggest that although alpha-tocopherol and urate provide important antioxidant defence in cancer, the association between their levels is weak.

However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy.
