Abstract：Objective To evaluate the application value of ultrasound-guided 125I particle implantation
in the treatment of chest wall metastasis. Methods According to the treatment planning system (TPS),
a proper number of 125I particles guided by ultrasound were implanted into the lesions of patients who
underwent percutaneous puncture. Results 435 125I particles guided by ultrasound were implanted into
17 lesions of 12 patients successfully. Results of the 17 lesions showed that complete remission (CR) was
achieved in 0 case, partial remission (PR) was achieved in 11 cases, no change (NC) was achieved in 4
cases and progression desease (PD) was achieved in 2 cases. Conclusion Ultrasound-guided 125I particle
implantation is an effective treatment method for chest wall metastatic carcinoma but its operation is
difficult.
