In recent years, the incidence of cancer is on the rise, and the mortality rate has been the first of all kinds of diseases, which will bring more and more threat to our health. At present, the main means of cancer treatment include surgery, chemotherapy, immunotherapy and the TCM treatment, but the above treatment has its limitations, such as tumor resection, not chemotherapy side effects or extremely poor cardiopulmonary function, the elderly can not tolerate surgery, leading to tumor treatment has little effect. Radioactive iodine particle therapy is a new technology in the treatment of tumor, which can make up for the defects of the above treatment methods, reach or approach the effect of surgery and other lesions.
Radioactive iodine particle therapy refers to the precise guidance of ultrasound, CT and computer three-dimensional stereotactic planning system, using special anti radiation implants by surgery or iodine 125 particle one-time permanent implantation of tumor tissue or implanted in the surgical excision of the residual tumor in the bed, and can determine the number of radioactive particles and radiation dose according to the implanted tumor or residual tumor bed size, which is safe, efficient, flexible and personalized features etc..
Compared with the traditional means of cancer therapy, the treatment of radioactive iodine particles are mainly the following advantages: 1, curative effect, wide range; 2, particle radiation in vivo is only 42.5px, to achieve precise radiotherapy, decrease the normal tissue dose; 3, by hand or percutaneous implantation, the wound is very small conformal radiation therapy; 4, continuous low dose, the tumor cells have uniform irradiation with tumor growth law; 5, the half-life of the radioactive source for 59.43 days, the effect of time in more than 200 days; 6, radiation source is always embedded in a special container, implanted during operation does not always contact particles, protection more security.
After lots of research and practice, the treatment of radioactive iodine particles can be used for the following reasons: (1) unable or unwilling to surgery and postoperative recurrence of cancer patients with; (2) untreated primary tumors, such as prostate cancer, lung cancer and so on; (3) the need to retain the important function of organs or surgery the involved organs tumors, such as deep brain tumors; (4) patients to curative resection of the tumor, such as thyroid cancer, endometrial cancer, carcinoma of tongue; (5) for the prevention of tumor local or regional diffusion operation, enhancing effect of cure, prevention of implantation; (6 metastatic tumor lesions) or postoperative solitary tumor metastases, lost the operation value, such as multiple metastatic tumors of the lung; (7) for unresectable primary tumors, such as hepatocellular carcinoma, lung cancer, nasopharyngeal carcinoma; (8) insufficient dose of external irradiation, as a local agent The amount of radiation; (9) ineffective or failed cases (10); drug resistance; (11) surgery residual tumor or tumor margin distance too close (< 0.5< span=" " > cm). Local severe symptoms, causing greater pain to the patient, although there are distant metastases, can also be implanted particles, to achieve palliative treatment, reduce pain, prolong life, improve the quality of life purposes.
Radioactive iodine particle therapy has been widely used in lung cancer, liver cancer, prostate cancer, brain tumors, head and neck cancer, superficial tumor, esophageal cancer, colorectal cancer, pancreatic cancer, renal and adrenal tumors, nasopharyngeal carcinoma, cervical cancer, ovarian cancer, breast cancer, gastric cancer, tongue cancer, laryngeal carcinoma, parotid carcinoma, tonsillar cancer, gum cancer, thyroid cancer, pleural mesothelioma, osteosarcoma and metastatic bone cancer, lymphoma, lymph node metastasis, uterine muscle tumor, endodermal sinus tumor, ethmoid bone, skin cancer, fibrosarcoma neurofibrosarcoma, thymic carcinoma spermatogonial cell tumor, rhabdomyosarcoma, sinus liposarcoma, fibrosarcoma, dermatofibrosarcoma protuberans and basal cell carcinoma, bladder cancer, liver hemangioma and orbital tumors (malignant melanoma, retinoblastoma), and the treatment of vertebral vertebral tumor.
