儿童急性淋巴细胞白血病治疗失败原因分析

论文摘要

目的:总结和分析我院儿童ALL治疗失败的主要原因及影响因素,探讨相应的改善措施;并对两个阶段使用的化疗方案进行经济学评价,为临床治疗方案的选择提供客观的依据。方法:采用回顾性调查,分析自1998年至2006年12月期间在我院新诊断的ALL患儿治疗失败的主要原因及相关影响因素,并对两个方案的化疗住院成本进行成本最小化分析。结果:新诊断ALL患儿共计231例,总治疗失败率63.6%(147/231例),第一阶段(1998.1-2003.5)的治疗失败率高于第二阶段(2003.6-2006.12)(75.6%vs50.9%,p<0.001)。总依从失败率为48.1%(111/231例),其中早期依从失败率为31.6%(73/231例),中期依从失败率为10.4%(24/231例),晚期依从失败率为6.1%(14/231例);第一阶段的依从失败率高于第二阶段(57.1%vs38.4%,p=0.004),影响我院ALL患儿治疗依从性的负性因素包括:年龄(1岁以下)、性别(男孩)、地域(外地)及治疗方案(荣成98方案)。能坚持化疗的患儿共计120例,总初治复发率为15.8%(19/120例),10岁以上患儿组的复发率为37.5%,高于10岁以下患儿组(p=0.011);总治疗相关死亡率为14.2%(17/120例),主要死亡原因是感染;初治复发率和治疗相关死亡率在前后两个阶段并无显著差异(p>0.05)。荣成98方案、改良BFM-2002方案和上海协作组高危方案的治疗复发率分别为23.5%(12/51例)、8.3%(5/60例)和22.2%(2/9例),三个方案的治疗相关死亡率分别为19.6%(10/51例)、10%(6/60例)和11.1%(1/9例)。荣成98方案与改良BFM-2002方案治疗的非高危组患儿平均住院费用分别为176947.2±74844.0元和92065.48±29782.35元,两者具有显著统计差异(p<0.001),并且前组的治疗相关不良反应高于后组(p<0.05),所需的支持费用也更高。结论:治疗依从失败是导致ALL儿章治疗失败的首要原因,不容忽视;治疗相关死亡率偏高,有待进一步减少。
