摘要
背景与目的:放射治疗是鼻咽癌治疗的主要治疗手段,放射性脑病(Radiation Encephalopathy,REP)是最为严重的并发症之一,这种损伤往往是不可逆转的,极大地影响病人的生存质量和生存期。本文探讨鼻咽癌放疗后REP的临床特点。方法:回顾性分析1172例鼻咽癌放疗患者的临床资料,总结首程放疗后和再程放疗后REP患者的临床特点。结果:鼻咽癌再程放疗患者REP发生率(16.8%)明显高于首程放疗者(1.5%,P<0.05);再程放疗后REP中位潜伏期(19个月)明显短于首程放疗后REP中位潜伏期(50个月,P<0.05)。再程放疗剂量<56Gy脑损伤发生率3.0%,56~66Gy发生率6.4%,>66Gy发生率8.4%(P<0.05)。结论:鼻咽癌放疗后REP发生率与放疗程数,放疗剂量有明显相关性。
BACKGROUND OBJECTIVE: Radiotherapy is a major treatment modality for nasopharyngeal carcinoma(NPC).Radiation encephalopathy(REP) is one of most severe complications of radiotherapy.The injury is always irreversible,it has a negative impact on the quality of life and survival of NPC patients.Our purpose is to study the clinical characteristics of patients with REP after radiotherapy in NPC patients.METHODS: The clinical data of 1172 patients with NPC were retrospectively analyzed,and the clinical features of REP after single-course radiotherapy and repeated radiotherapy were summarized.RESULTS: The incidence of REP in repeated radiotherapy group(16.8%) was higher than that in single-course radiotherapy group(1.5%,P〈0.05).The median latency period of REP was shorter in repeated radiotherapy group(19 months) than that in single-course radiotherapy group(50 months,P〈0.05).The incidence of REP was 3.0% in repeatedly irradiated patients with a dose 〈56 Gy group,6.4% with a dose 56~66 Gy,and 8.4% with radiation dose〉66 Gy(P〈0.05.CONCLUSION: The incidence of REP after radiotherapy in NPC patients has significant correlation with the course of radiotherapy and radiation doses.
