ABSTRACT
Objective To evaluate the clinical value of CT-guided interstitial implantation of ~(125)I seeds for the treatment of pulmonary carcinoma. Methods A total of 18 patients with pulmonary carcinoma underwent CT-guided interstitial implantation of ~(125)I seeds. According to the size of tumor,effective dose, and optimal quantity of ~(125)I seeds to the patient that were computed by a developed algorithm in Treatment Planning System (TPS), the ~(125)I seeds were implanted into the tumor tissues under the guidance of spiral CT. The patients were reexamined by CT 2 months after the operation and were followed up for 6 months. Results A total of 812 seeds were implanted into the 18 lesions in the 18 cases (45.1 seeds per case in average). The CT scan performed 2 months after the operation showed CR in 7 cases, PR in 10, and NC in 1. The total effectiveness (CR+PR) rate was 94% (17/18). Conclusions CT-guided interstitial implantation of ~(125)I seeds is a effective, minimally invasive, and low toxic method for valid and minimally traumatic treatment for middle- and late-stage lung cancer. Further application and long-term observation are necessary.
