125 iodine seed implantation is an effective technique for the treatment of malignant tumors, which belongs to a kind of brachytherapy. The method can be implanted into the lymphatic channels or lymph nodes of tumor metastasis by minimally invasive (percutaneous) or surgical implantation of radioactive 125 iodine particles into the tumor or the tumor invasion. Low dose of gamma rays emitted 125 iodine particle decay process, continuous uninterrupted irradiation of tumor tissue, can kill tumor cells and the surrounding fission in different periods of hypoxic cells, therefore, can be effective in the treatment of tumor, prevent tumor recurrence and metastasis.

125 iodine particle implantation indications:

1 untreated primary tumors, such as prostate cancer, lung cancer, etc.

2 the need to retain the important functions of the organization or the operation will be accumulated in important organs such as tumor, 3 patients with deep brain tumors refused radical surgery cases, such as the diffusion of thyroid cancer, cervical cancer, lung cancer and 4 cancer prevention in local area, enhance the preventive effect of implantation of radical 5 metastatic tumor lesions or after isolation tumor metastasis, such as lung metastatic tumor

6 unresectable primary liver cancer, nasopharyngeal carcinoma cases, such as the giant 7 external irradiation ineffective or failure of 8 cases of external irradiation dose, as a palliative treatment of locally advanced tumor in 9 doses (such as lung cancer, pancreatic cancer)

Contraindications 125 iodine implantation therapy: 1 significant organ dysfunction 2 estimated survival does not exceed half 3 with widespread metastatic tumors in 4 ulcers period

What are the advantages of iodine 125 particle implantation? 1 tumor iodine 125 seeds implantation in the treatment of advanced technology, good curative effect, little side effect; 2 chemotherapy can also 125 iodine seed implantation, chemotherapy coverage area, implantation of iodine 125 prominent "point" and "point," combined with the comprehensive treatment; 3.CT, MRI or ultrasound guided percutaneous puncture, 125 iodine the particle implantation, the effect can be achieved without surgical knife, but the trauma, 2 days after operation; 4 patients in the 125 iodine seed implantation, can expand the range of surgical treatment, to obtain better efficacy for treatment; 5 iodine seed implantation in the treatment of 125 chemotherapy ineffective treatment is the best choice for patients with 6 iodine; although 125 particle radioactive iodine 125, but particle range 42.5px, without taking account of environmental pollution and protection;
