Abstract:: |
Reduction of pulmonary metastases was observed in tumor-bearing mice exposed to low-dose whole body X-irradiation.The anti-metastasis was better when low-dose X-irradiation was used in combination with low-dose cyclophosphamide.The activities of murine splenic NK cells and II-2- induced LAK cells, and the reactivity of splenocytes to IL-2 increased significantly in tumor-bearing mice treated with low-dose X-irradiation.These anti-tumor immune fuctions were also augmented in the mice treated with both low-dose X-irradiation and cyclophosphamide.These results domonstrated that low-dose X-irradiation had effective antimetastastic effect through the activation of the in vivo anti-tumor immunity, thereby providing a reliable evidence for the possibility of its clinical application. |
