Clinical application of percutaneous implantation of ~(125)I seeds for treating malignant tumor / 介入放射学杂志

Objective To investigate the therapeutic mechanism of ~(125)I seeds based on physical properties, the significance of therapeutic planning system (TPS), the therapeutic means and the clinical efficacy. Methods Eighteen cases with advanced carcinoma were treated through percutaneous implantation of 125 I for interstitial radiotherapy. Results No serious complications occurred in the patients after radiotherapy associated with apparent improved living quality. Two months after therapy, the tumors had shrunk in different degrees with conspicuous decrease in 12, of which 5 tumors disappeared. Conclusions Short-term efficacy demonstrates that intra-tissue radiotherapy of ~(125)I had significant efficacy for advanced tumors.
