    Most studies of children with prolonged fever and neutropenia (PFN) have focused on invasive fungal disease (IFD) as the etiology of fever and not on other causes. Data are lacking regarding risk factors and adverse outcomes in pediatric cancer patients with PFN compared with those whose fevers resolve more rapidly. Retrospective medical record review was performed for all cancer patients with febrile neutropenia (FN) in the pediatric oncology unit at University of Chicago Medicine Comer Children’s Hospital from March 2009 to July 2016. Resolving febrile neutropenia (RFN), lasting less than 96 hours, and PFN episodes (≥ 96 hours) were compared to identify risk factors and outcomes associated with PFN. A total of 572 FN episodes were identified in 265 patients. PFN occurred in 119 (21%) FN episodes (50 patients) and RFN occurred in 453 (79%) FN episodes (215 patients). In multivariable analysis, autologous stem cell transplant (odds ratio [OR] 6.5, P <0.001), fever >39°C at the time of presentation (OR 2.4, P<0.01) and absolute monocyte count (AMC) <100 cells/m3 (OR 2.7, P=<0.01) were independently associated with PFN. Pneumonia, neutropenic enterocolitis and IFD were more common etiologies of fever in PFN compared with RFN. Patients with PFN were more likely to be admitted to the pediatric intensive care unit [OR 3, (95%CI, 1.66%-5.28%), P<0.001] and had a trend toward higher 30-day mortality [OR 3.8, (95%CI, 0.52%-29.32%), P=0.07]. Patients with PFN are at increased risk for serious illness and death. A better understanding of the etiologies of PFN other than IFD is needed to be able to appropriately diagnose and treat this high-risk group.
