Efficacy analysis of PEG-rhG-CSF as primary prophylaxis in senile lymphoma patients
-
摘要: 目的:评价聚乙二醇化重组人粒细胞集落刺激因子(PEG-rhG-CSF)应用于预防老年淋巴瘤患者化疗后引起中性粒细胞缺乏(粒缺)的有效性和安全性。方法:回顾性分析84例老年(≥ 60岁)淋巴瘤化疗患者的病例资料。根据个人意愿,36例患者接受PEG-rhG-CSF作为初级预防(试验组);48例未预防性使用PEG-rhG-CSF(对照组),比较2组患者出现3~4级粒缺的情况及药物所致不良反应。结果:试验组和对照组中分别有61.1%和87.5%的患者在全部化疗周期中出现过3~4级粒缺,差异有统计学意义(P=0.005)。亚组分析显示,60~69岁患者中,试验组3~4级粒缺的发生率显著低于对照组(62.1%:86.5%,P=0.022);70岁及以上患者中,试验组3~4级粒缺的发生率有降低趋势,但与对照组比较差异无统计学意义(57.1%:90.9%,P=0.137)。在接受PEG-rhG-CSF预防性应用的36例患者中,有8例(22.2%)出现药物相关性不良反应,主要表现为轻微骨痛。结论:对于接受21 d CHOP±R化疗方案的老年淋巴瘤患者,每疗程一剂6 mg PEG-rhG-CSF能有效减少3~4级粒缺的发生,疗效显著,且不良反应发生率低,程度轻。

Abstract: Objective:To evaluate the safety and efficacy of pegylated recombinant human granulocyte colony-stimulating factor (PEG-rhG-CSF) as primary prophylaxis for chemotherapy-induced neutropenia in senile lymphoma patients.Method:A total of 84 elder lymphoma patients (≥ 60 years old) treated with chemotherapy were included.Among them,36 patients receiving PEG-rhG-CSF as primary prevention were considered as the prevention group;48 patients without PEG-rhG-CSF injection were recruited as the control group.The incidence of grade 3-4 neutropenia of two groups and the adverse events induced by PEG-rhG-CSF were recorded and compared.Result:61.1% patients in prevention group and 87.5% patients in control group had experienced grade 3-4 neutropenia respectively.There was significant difference between the two groups (P=0.005).Subgroup analysis showed significant lower incidence of grade 3-4 neutropenia in the prevention group (62.1% vs 86.5%,P=0.022) for patients of 60-69 years old.For patients aged 70 and over,lower incidence of grade 3-4 neutropenia was also observed in the prevention group,but the difference was not statistically significant (57.1% vs 90.9%,P=0.137).As for adverse events of PEG-rhG-CSF,8 cases in 36 patients (22.2%) experienced slight bone pain.Conclusion:In senile lymphoma patients undergoing 21 d-CHOP±R regimen,a single dose of 6 mg PEG-rhG-CSF demonstrated significant prophylaxis for grade 3-4 neutropenia,with low incidence of adverse events and mild adverse events. -
