【摘要】 目的 研究重组人促血小板生成素(rhTPO)治疗急性髓系白血病(AML)患者化疗后血小板减少的疗效及不良反应发生情况。方法 51例AML化疗后出现血小板减少的患者, 随机分为实验组(26例, 给予rhTPO治疗)与对照组[25例, 给予重组人白细胞介素-11(rhIL-11)治疗]。比较两组患者化疗后血小板恢复的水平、血小板<50×109/L的持续天数、恢复至75×109/L所需天数和恢复至100×109/L所需天数, 以及两组的不良反应发生率。结果 治疗后, 实验组血小板水平显著高于对照组(P<0.05), 血小板<50×109/L的持续天数及恢复至75×109/L、100×109/L所需的天数明显少于对照组(P<0.05);实验组不良反应发生率低于对照组(7.7% VS 40.0%) (P<0.05)。结论 rhTPO能有效促进AML患者化疗后的血小板恢复, 且不良反应发生率低。

【Abstract】 Objective To research curative effect and adverse reactions by recombinant human thrombopoietin (rhTPO) in the treatment of post-chemotherapy thrombocytopenia in acute myelogenous leukemia (AML) patients. Methods A total of 51 AML patients with post-chemotherapy thrombocytopenia were randomly divided into experimental group (26 cases, rhTPO treatment) and control group [25 cases, recombinant human interleukin-11 (rhIL-11) treatment]. Comparisons were made on post-chemotherapy blood platelet recovery degree, duration time <50×109/L, recovery days to 75×109/L, 100×109/L, and incidence of adverse reactions. Results After treatment, the experimental group had much higher blood platelet level than the control group (P<0.05), and its duration time <50×109/L, recovery days to 75×109/L, 100×109/L were less than the control group (P<0.05). The experimental group had lower incidence of adverse reactions than the control group (7.7% VS 40.0%) (P<0.05). Conclusion rhTPO can effectively accelerate post-chemotherapy blood platelet recovery in AML patients, along with low incidence of adverse reactions.

AML是起源于造血干、祖细胞的髓系恶性克隆性肿瘤, 其主要治疗方案为联合化疗使患者获得完全缓解, 延长生存期[1]。但是, 化疗后骨髓抑制期出现进行性血小板减少, 增加了患者的致命性出血风险, 甚至使后续化疗延迟。传统方法是在血小板减少期间给予血小板输注及预防性应用止血药物, 但是血源紧张, 经输血传播疾病, 以及多次输注血小板导致的血小板抗体产生, 甚至血小板输注无效, 往往危及患者生命等诸多问题亟待解决。近年来, rhTPO逐渐应用到肿瘤患者化疗所致血小板减少的治疗中[2]。针对rhTPO应用的疗效及安全性问题, 本文回顾性分析51例AML化疗后血小板减少患者的临床资料, 总结分析如下。
