摘要 目的:研究急性早幼粒细胞白血病(APL)预后与外周血WBC计数的关系。方法:根据外周血WBC计数将83例初治APL患者分为4组:第1组WBC<4×109/L,43例;第2组WBC4~10×109/L,9例;第3组WBC>10~15×109/L,8例;第4组WBC>15×109/L,23例。动态观察治疗过程中外周血WBC计数及形态学、APTT、PT、TT、Fbg、DD、ATA、骨髓象的变化,4组均以亚砷酸(As2O3)或全反式维甲酸(ATRA)为主的诱导缓解方案治疗,比较其弥漫性血管内凝血(DIC)的发生率、早期死亡(ED)率、一次化疗完全缓解(CR)率。结果:4组DIC的发生率分别为23.3%、11.1%、37.5%、56.5%,ED率为11.6%、0%、37.5%、65.2%,总CR率80.0%、100%、71.4%、33.3%。前三组之间DIC的发生率、ED率、CR率差异均无统计意义,与第4组比较差异均有统计学意义(均P<0.01)。4组均完成足疗程治疗的患者的CR率分别为84.2%、100%、100%、62.5%;差异无统计学意义(P>0.05)。结论:初治时外周血WBC数超过15×109/L是APL预后不良的危险因素之一。
