Purpose To evaluate the influence of brainstem dose limitations on tumor dose in locally-advanced nasopharyngeal cancer (NPC).Methods Retrospective analysis of the prognostic value of the distance between the primary tumor and brainstem (Dbs) in 358 patients with locally-advanced NPC after intensity-modulated radiation therapy.

目的 回顾性分析早期宫颈癌术后调强放疗(IMRT)和三维适形放疗(3D-CRT)的预后及生存质量情况,从而探讨IMRT能否提高早期宫颈癌术后患者的治疗增益比.方法 收集2007年7月-2015年2月,FIGO分期为ⅠB-ⅡA期具有不良预后因素的宫颈癌术后患者共148例.其中IMRT组100例,3D-CRT组48例.采用单因素分析各种影响预后因素;Kaplan-Meier法计算总生存率及无复发生存率

放射治疗是胸部肿瘤的主要治疗方法之一,在肿瘤接受放射治疗的过程中,设计照射野时常不能完全避开肺,即使采用三维适形或调强放疗,肺也不可避免地受到不同程度的照射,从而引起放射性肺损伤,目前已成为胸部肿瘤治疗的常见并发症,不仅影响治疗效果,降低肿瘤局控率,而且对患者的生活质量及生存期造成严重影响.本文就放射性肺损伤的发病机制、影响因素、防护技术、防护药物的研究进展作一简要综述.

目的 观察氨溴索与生脉注射液联合对老年胸部肿瘤放疗致急性放射性肺炎的预防作用.方法 将64例接受三维适形放疗的老年胸部肿瘤患者随机分为观察组和处理组,观察组单纯接受放疗,处理组在放疗开始时即给予氨溴索与生脉联合治疗,比较两组急性放射性肺炎的发生情况.结果 处理组的急性放射性肺炎发生率明显低于观察组(P<0.05),其发生时间也较观察组明显延迟(P<0.05).

原发性肝癌(primary hepatocellular carcinoma,PHC)是全球高发的恶性肿瘤之一,具有病死率高、进展快、易复发等特点.目前,PHC的治疗方法主要包括手术、放疗、化疗和生物治疗,其中以手术治疗最为理想.PHC发病隐匿,约85%的患者就诊时就因多发病灶、病灶靠近重要血管和并发肝硬化等而失去了最佳手术时机[1].而放疗是治疗不能手术的PHC的主要方法,但它在杀灭肿瘤细胞的同
