在人类和实验动物的许多器官中放射诱发肿瘤历有叙述。早已报道中枢神经系统肿瘤可以成为头皮良性疾病(发癣)放射治疗后的晚期合并症。近二、三十年来,原发性中枢神经系统恶性肿瘤放疗后病人生命比过去延长很多,放射致癌效应才有足够时间表现出来,文献间有个案报道。作者报告了3例第二个肿瘤,据情足以支持是放射诱发的。 首先明确证实辐射乃人脑肿瘤的病因者是Israeli,他对50年代放射治疗儿童发癣11000例的回顾性研究中,与年龄配对的对照组比较起来,受照组儿童发生头、颈部良、恶性肿瘤(包括脑瘤)的危险性较高。这些病例中、放疗至诊断肿瘤之间的相隔时
Radiation-induced tumors have been described in many organs of humans and laboratory animals. It has long been reported that CNS tumors can become a late comorbid condition after radiotherapy for benign scalp diseases (hair ringworm). Nearly two to three decades, the primary CNS malignant tumor patient life after radiotherapy much longer than in the past, radiocarcinoma effect has enough time to show, there is a case report between the literature. The authors reported a second tumor in three cases, which is, according to circumstances, sufficient to support radiation-induced. First clear that radiation is the cause of human brain tumors is Israeli, he retrospective study of 11,000 cases of children with ringworm radiation therapy in the 1950s, compared with age-matched control group, the irradiated group of children with head and neck good , Malignant tumors (including brain tumors) higher risk. In these cases, radiotherapy to diagnose the tumor when the interval between
