Abstract:
Objective To investigate the safety and efficacy of CT-guided 125I seed implantation in the treatment of metastatic lymph nodes within the abdomen.Methods Data of 55 patients who underwent CT-guided 125I seed implantation with a total of 63 metastatic lymph nodes within the abdomen were retrospectively analyzed.The efficacy was evaluated.Results 125I seeds were successfully implanted in all 55 patients,and the radiation dose reached the pre-operation plan requirements.The response rate of 1,3,6,9 and 12 months after operation was 76.19％ (48/63),80.65％ (50/62),71.43％(30/42),77.50％(31/40) and 78.95％(30/38),respectively.And the clinical benefit rate was 93.65％(59/63),88.71％(55/62),80.95 ％ (34/42),85.00％(34/40) and 84.21％(32/38),respectively.There were 42 patients combined with abdominal pain and back pain before the operation.Among them,39 patients (39/42,92.86％) relieved 1 month after operation.No severe complication occurred intraoperatively or postoperatively,such as inhibition of bone marrow,bleeding or infection.The survival rate of 1,3,6,9 and 12 months postoperatively was 100％,98.20％,61.80％,58.20％ and 54.50％,respectively.Conclusion CT-guided 125I seed implantation is one of the safe and effective methods for treating metastatic lymph nodes within the abdomen.
