Aim: Febrile neutropenia is an important cause of mortality and morbidity in hematology–oncology patients undergoing chemotherapy. The objective of this study was to evaluate febrile neutropenic episodes in children with malignancy.


Material and Methods: Sixty-eight children who received chemotherapy for malignancy between 2010 and 2015 were retrospectively reviewed. The demographic characteristics, laboratory data, infection foci, and frequency of microorganisms grown in culture were examined. Also, the frequency of febrile neutropenic attacks was investigated according to the chemotherapy periods.


Results: Of the total 200 episodes, 81 (40.5%) were clinically documented, and 73 (36.5%) were microbiologically documented infections. Fever of unknown origin was observed in 46 (23%) episodes. The most frequently clinically documented focus were mucositis (33.4%) and pneumonia (24.7%). Blood culture was positive in 55 (75.3%) episodes of microbiologically documented infections. The most commonly isolated microorganisms in blood culture were Gram-negative bacteria (47.2%). C-reactive protein levels in microbiologically documented infections were higher than in clinically documented infections, and fever of unknown origin (p<0.05, for both). The most common underlying malignancy was acute lymphoblastic leukemia (73.5%). The highest proportions (34.6%) of febrile neutropenic episodes were observed during the reinduction period for these children. Nine (13.2%) children died of neutropenic sepsis.


Conclusions: Febrile neutropenia continues to be an important cause of mortality in pediatric patients with malignancy. C-reactive protein levels may be an indicator for predicting bacterial infection in children with febrile neutropenia without apparent focus. The most frequently isolated agents in our center were Gram-negative microorganisms. Determining the microbial flora of each center may be beneficial to improving survival rates.
