Experimental Research In Rabbits VX₂ Malignant Liver Tumor Treatment With ～(125)I Seeds Brachytherapy Under CT Guidance

¹²⁵I seeds interstitial brachytherapy is a new kind of method to treat with malignant tumors. The aim of the experimental research through animals is to investigate the therapeutic effect and the pathological changes on rabbits' VX₂ liver tumor treated with ¹²⁵I seeds interstitial brachytherapy and percutaneous ethanol injection (PEI) under CT guidance. We aim to identify the therapeutic effect and the criterion of ¹²⁵I seeds radiant activity selection, optimize the therapeutic regimen, investigate the tissue damage, its' prothetic time and the relationship between time and dosage effect, and approach to provide fundamental theories for ¹²⁵I seeds clinical using and arrive at the best dosage range of ¹²⁵I seeds interstitial brachytherapy. And it can become a new and effective kind of therapies to be applied for the clinical treatment to mid-advanced stage and recurring liver tumor.
