摘要 20世纪80年代欧洲和美国开始运用高剂量率(high dose rate,HDR)近距离放射疗法治疗中高危前列腺癌。HDR作为剂量提升的有效方法可与外照射联合应用。William Beaumont医院剂量提升研究证实这种联合治疗安全有效。研究表明前列腺癌α/β比值远低于之前的认识,前列腺癌放射生物学认识发生巨大转变。单次剂量高于常规剂量照射的大分割模式应运而生。低毒和联合外照射治疗临床研究,使高剂量率近距离放射治疗趋于成为低中危前列腺癌治疗唯一有效的器官保留治疗方式,开启前列腺癌治疗器官保留治疗新时代,本文旨在对HDR联合外照射疗法和单一HDR疗法的文献进行回顾,对临床结果及毒性反应进行分析。
