【摘要】：目的·研究神经母细胞瘤高危组患儿化学治疗(化疗)后外周血中性粒细胞和淋巴细胞的水平、严重感染率及与化疗组合的关系,为高危组患儿化疗后预防感染提供指导。方法·分析自2012年7月至2015年9月在上海交通大学医学院附属新华医院首诊住院的神经母细胞瘤高危组患儿45例,记录化疗方案及化疗后反应,记录化疗第1、第5、第10、第15及第20日的中性粒细胞及淋巴细胞绝对值,随访并记录化疗后的感染情况,进行统计学分析。结果·化疗后中性粒细胞及淋巴细胞在每轮化疗第10日左右降至最低,第15日左右上升。感染发生与第10日的中性粒细胞(r=-0.245)及淋巴细胞(r=-0.227)数量呈负相关。淋巴细胞在4轮化疗后进入持续性淋巴细胞缺乏期。神经母细胞瘤高危组化疗后Ⅳ级骨髓抑制达90.0%,严重感染率达15.5%,3个化疗药物组合之间在Ⅲ级(P=0.008)和Ⅳ级骨髓抑制(P=0.001)及严重感染发生方面(P=0.010)差异统计学意义。结论·神经母细胞瘤高危组儿童化疗后有明显的骨髓抑制和较高的感染发生率,尤其是环磷酰胺+阿霉素+长春新碱组合,需重视此组儿童化疗的耐受度,积极采取措施以降低严重感染率。
[Abstract]:Objective to study the level of neutrophils and lymphocytes in peripheral blood of children with high risk neuroblastoma after chemotherapy (chemotherapy), the serious infection rate and the relationship with chemotherapy combination, so as to provide guidance for the prevention of infection after chemotherapy in high risk group. Methods from July 2012 to September 2015, 45 children with high risk neuroblastomas were admitted to Xinhua Hospital affiliated to Medical College of Shanghai Jiaotong University. The chemotherapy regimen and post-chemotherapy reaction were recorded. The absolute values of neutrophils and lymphocytes on the 1st, 5th, 10th, 15th and 20th day of chemotherapy were recorded. The infection after chemotherapy was followed up and recorded. Results after chemotherapy, neutrophils and lymphocytes decreased to the lowest on the 10th day of each round of chemotherapy and increased around the 15th day. The incidence of infection was negatively correlated with the number of neutrophils (r 鈮，
