摘要
目的通过了解肿瘤患者放化疗前后外周血细胞参数的变化情况,确定反映肿瘤患者骨髓造血功能抑制和恢复的早期指标。方法采用Sysmex XT-2000i全自动血细胞分析仪对50例肿瘤患者放化疗前后外周血白细胞(WBC)、中性粒细胞(NEU)、网织红细胞百分数(Ret%)、未成熟网织红细胞比率(IRF)进行检测。结果肿瘤患者放化疗后骨髓造血功能受到抑制,与放化疗前相比,IRF、Ret%从放化疗后第3天起明显下降,差异有统计学意义(P<0.05),较WBC、NEU明显下降要早3天;IRF于放化疗后第15天开始增高,与第10天相比差异有统计学意义(P<0.05),较Ret、NEU明显回升要早5天。结论在肿瘤患者放化疗过程中,IRF是反映骨髓造血功能抑制和恢复的一项非常敏感的早期指标。
Objective To investigate the changes of peripheral blood parameters before and after radiotherapy and chemothera-py ,and establish an early index that can reflect the suppression and recovery of the bone marrow hematopoietic function in patients with tumor .Methods The white blood cell（WBC） ,neutrophils（NEU） ,the percentage of reticulocyte（Ret% ） and the immature re-ticulocyte fraction（IRF） of peripheral blood were detected by Sysmex XT-2000i automatic blood cell analyzer before and after radio-therapy and chemotherapy in 50 patients with tumor .Results Bone marrow function was suppressed after radiotherapy and chemo-therapy .Compared with the value before radiotherapy and chemotherapy ,IRF and Ret% were significantly decreased on the 3rd day after therapy which was 3 days earlier than the change of WBC and NEU ,the difference was statistically significant （P〈0 .05） ,and compared with the value of the 10th day ,IRF began to rebound on the 15th day which was 5 days earlier than the change of Ret%and NEU ,the difference was statistically significant （P〈0 .05） .Conclusion IRF can be served as an early and sensitive indicator in monitoring the suppression and recovery of bone marrow hematopoietic function in the patients with tumor during radiotherapy and chemotherapy .
