摘  要:目的分析化疗后预防性使用重组人粒细胞集落刺激因子(rhG-CSF)的持续时间及影响因素。方法回顾性分析聚乙二醇化重组人粒细胞集落刺激因子(PEG—rhG—CSF)Ⅱ期和Ⅲ期临床研究中招募的受试者的临床病理特征。试验组患者皮下注射100仙g/kgPEG—rhG—CSF1次,对照组患者每天注射5I,Lg/kgrhG—CSF。结果在53个化疗周期中,rhG—CSF使用时间为(9.57±2.10)d;使用时间为7~11d者44例(83.0%)。体质指数和基线中性粒细胞绝对值(ANC)与rhG—CSF使用时间均有关(均P〈0.05)。多因素方差分析结果显示,基线ANC与rhG—CSF使用时间有关(P=0.019)。rhG—CSF最常见的不良反应为骨痛,不良反应均较轻,无因不良反应死亡患者。结论化疗后预防性使用rhG—CSF的中位时间为10d;基线ANC低的患者需要预防性应用rhG—CSF更长时间。临床试验注册美国临床注册中心。Objective To analyze the duration of preventive filgrastim administration as support for chemotherapy and its affecting factors. Methods Single institutional data from a phase U clinical trial and a phase IlI clinical trial of pegylated filgrastim were combined. In the two randomized cross-over trials, patients with previously untreated cancer received two cycles of chemotherapy of the same regimen. In the study group, the patients received a single subcutaneous injection of 100 p^g/kg pegylated filgrastim, and in the control group, they received daily subcutaneous injections of 5 ~g/kg filgrastim. Results In 53 chemotherapy cycles, the median duration of filgrastim administration was (9.57_+2.10)d. 83.0% (44/53) of them received filgrastim for 7-11 days. Patients with baseline absolute neutrophil count of 〈4x 109/L or body mass index less than 22 received a longer filgrastim prophylaxis (P 〈 0.05 ). Results of muhivariate analysis showed that the baseline absolute neutrophil count is associated with the time of filgrastim administration(P=0.019). The most common adverse event of rhG-CSF was skeletal pain, generally mild and no treatment-related death occurred. Conclusions The median duration of filgrastim support for chemotherapy was 10 days. Patients with lower baseline neutrophil count require a longer filgrastim prophylaxis. Trial registration: ClinicalTrials.gov identifier, NCT01285219
