Abstract
To investigate the clinical value of CT guided radioactive seed (125)I implantation in treating bone metastasis. 28 multiple bone metastatic tumor patients with 116 metastatic lesions totally, adenocarcinoma of lung in 6 cases, squamous cell carcinoma of lung, renal clear-cell carcinoma, and carcinoma of prostate in 4 cases each, hepatocellular carcinoma and colon carcinoma in 3 cases each, breast carcinoma in 2 cases, and malignant schwannoma and pancreatic cancer in 1 case each, 13 males and 15 females, aged 49.8, underwent CT guided radioactive seed (125)I implantation into bone metastatic lesions. In these 28 cases, complete pain relief (CR) was observed in 16 cases, partial relief (PR) in 7 cases, and no change (NC) in 5 cases with an effective rate of 82.1%. Among the 116 lesions in these 28 cases local control (LC) was seen in 93 cases, NC in 17, and PD in 6. The response rate was 80.2%. CT guided radioactive seed (125)I implantation procedure has good clinical effects in treating bone metastasis with minimal invasive and few complications.
