简介:交替半身放射(alternativehemi-bodyirradiation,AHBI)治疗可清除体内残留的肿瘤细胞,重建造血功能,是一种治疗白血病、多发性骨髓瘤、恶性淋巴瘤的新方法。从1979年开始国外已有人用HBI治疗血液肿瘤,并取得一定效果,国内近5年开始应用于临床,至今已有报道。现综述如下:1AHBI的原理和方法1.1原理①根据白血病化疗后造血干细胞迁移早于残留白血病细胞的时差为理论依据,进行致死剂量交替半身照射,既清除了体内残留的白血病细胞,又由于造血干细胞从屏蔽骨髓中交替种植而重新造血,从而达到治疗白血病的目的。以大鼠急性粒细胞白血病为模型研究发现,骨髓内残留白血病细胞迁移的时间为11天以上。大鼠白血病大剂量化疗后周围血粒细胞集落刺激
