在许多癌症治疗时,采用越剧烈的方案,越有成效,便越倾向于抑制免疫系统。治疗由于这种抑制而并发的难免性感染已取得了很大的进展。中性白细胞减少症患者开始发热时即常规应用广谱抗生素,但每次由于出现更有侵袭力、更有抵抗的病原体而最后导致患者死亡。因此除了渴望出现更有效的药物外,还需要有一种能尽快检出患者有无感染以及是属于何种感染的较好方法,能较快速并敏感地检出血液中病原 In many cancer treatments, the more aggressive the scheme, the more effective it is and the more it tends to suppress the immune system. Great progress has been made in treating unavoidable infections complicated by this suppression. Broad-spectrum antibiotics are routinely used when neutropenic patients start fever, but each time they eventually die due to a more aggressive and more resistant pathogen. Therefore, in addition to being eager to find more effective drugs, there is also a need for a better method of detecting whether a patient has an infection as soon as possible and of what kind of infection it belongs to, and capable of detecting the pathogen in the blood more quickly and sensitively
