Abstract:
Objective To explore the clinical value of CT-guided 125I radioactive seeds implantation and chemical ablation for malignant retroperitoneal tumors.Methods Because of the rejection of the second surgery resection and insensitivity of chemotherapy and radiotherapy,nineteen patients with recurrent or metastasis malignant retroperitoneal tumors were treated by CT-guided125I radioactive seeds implantation according to TPS or Halarism's experienced function,and percutaneous ethanol injection was performed if the way of punctuation Was limited.The extent of pain relief was assessed one month later after therapy.All the patients received enhanced CT scan 6 months after the first treatment,and imaging evaluation wag performed according to WHO criteria.Results For the 19 patients.pain relief Was achieved more or less in all patients.Imaging evaluation revealed complete relief,partial relief,no change in 10,7,2 cases respectively.All patients are still alive now.The longest followed span is 31 months.and the shortest is 7 months,the average followed span is 13.5 months.Conclusion CT-guided 125I radioactive seeds implantation and chemical ablation ore effective for malignant retropefitoneal tumors.
