放射治疗可以诱发 恶性肿瘤,且多数患者未得到及时治疗,疗效较差,因此需要密切随访。本文报告12例放射诱发的恶性肿瘤,结合文献回顾对放射致癌的病因、发病机制、诊断、潜伏期与辐射剂量关系及防治进行了讨论。 Radiation therapy can induce malignant tumors, and most patients are not treated promptly and have poor efficacy. Therefore, close follow-up is needed. In this paper, 12 cases of radiation-induced malignant tumors were reported. Combined with the literature review, the etiology, pathogenesis, diagnosis, latency and radiation dose relationship and prevention and treatment of radiation carcinogenesis were discussed.
