放射性粒子肿瘤内植入治疗属于放射治疗中的内放疗,是永久性植入组织间近距离放射治疗。目前应用放射性粒子治疗适用于胰腺癌、原发性肝癌及肝转移癌、复发性直肠癌、肺癌及肺转移癌、前列腺癌、脑肿瘤、颌面部肿瘤、骨转移瘤等恶性肿瘤已经取得较好疗效,可以明显延长生存期,提高生活质量,亦可使许多患者临床症状得到有效缓解。放射性粒子植入是在CT或超声的导向下,将放射性粒子精确地植入肿瘤区域,放射性粒子植入区域与肿瘤外形高度一致,可让肿瘤靶区得到相当高的根治剂量,确保最大限度的杀伤肿瘤组织。
Radioactive intracavitary tumor implantation is radiation therapy in the internal radiation therapy, is a permanent implantation of tissue brachytherapy. The current application of radioactive particle therapy for pancreatic cancer, primary liver cancer and liver metastases, recurrent rectal cancer, lung cancer and lung metastases, prostate cancer, brain tumors, maxillofacial tumors, bone metastases and other malignant tumors have been made more Good curative effect, can significantly prolong survival and improve quality of life, but also can effectively alleviate the clinical symptoms of many patients. Radioactive particle implantation is guided by CT or ultrasound, the radioactive particles are precisely implanted in the tumor area. The radioactive particle implantation area is highly consistent with the tumor appearance, which can achieve a fairly high radical dose in the tumor target area to ensure the maximum Tumor tissue.
