To provide an update on the rational approach of febrile neutropenia in children with cancer and discuss future research aspects in the field.
Clinical and laboratory variables and new biomarkers associated with an increased risk for a severe outcome including invasive bacterial infection (IBI), sepsis, and mortality have been identified for children with cancer and febrile neutropenia. These variables and biomarkers are currently being used for an early risk assessment in order to identify children at low or high risk for IBI or at high risk for sepsis and death. Early identification of children with a differential risk has allowed the implementation of selective treatment regimens. More recently, host genetic differences have been associated with a differential risk for IBI. The individual gene profile based on selected polymorphisms could further fine-tune the early risk assessment allowing tailor-made management strategies.
In the last decades, efforts have focused on the stratification of the heterogeneous group of children with cancer and febrile neutropenia according to their risk for developing an IBI. This effort has allowed a less aggressive treatment strategy for children at low risk, including early hospital discharge and use of intravenous and oral antimicrobials at home. More recently, advances have been made in the early identification of children in the other spectrum of infection, those at high risk for sepsis and mortality, with the aim of rapid implementation of aggressive therapy.
提供癌症儿童中性粒细胞减少性发热的合理处理方法的最新进展,并讨论该领域的未来研究方向。
已经确定了与癌症合并中性粒细胞减少性发热儿童发生严重后果(包括侵袭性细菌感染[IBI]、败血症和死亡)风险增加相关的临床和实验室变量以及新的生物标志物。目前,这些变量和生物标志物用于早期风险评估,以识别 IBI 低危或高危以及败血症和死亡高危的儿童。早期识别具有不同风险的儿童,使得可以实施选择性治疗方案。最近,宿主遗传差异与 IBI 的不同风险相关。基于选定多态性的个体基因谱可以进一步微调早期风险评估,从而制定个体化的管理策略。
在过去几十年中,人们致力于根据癌症合并中性粒细胞减少性发热儿童发生 IBI 的风险对异质性群体进行分层。这一努力使得低危儿童的治疗策略不那么激进,包括早期出院以及在家中使用静脉和口服抗生素。最近,在识别感染谱另一端的儿童(即败血症和死亡率高风险的儿童)方面取得了进展,目的是快速实施积极治疗。
