Effect of small doses of ionizing radiation on selected antioxidant and immunologic parameters in patients with cervical cancer

We analyzed the indices of antioxidant and immune systems in 69 patients with cervical carcinoma T3NxMo at different stages of radiotherapy. Radiation doses of 10-20 Gy were followed by certain normalization of antioxidant enzyme levels, increased concentrations of vitamins E and A in immunocompetent blood cells and improved the penetration and elastic properties of formed cells. The dosage stimulated the activity of helper-inducing and cytotoxic T-cells. Such effects should be taken into account when working out regimens of complex treatment of locally-advanced cervical carcinoma which include cytostatic drugs and radiation.
