Abstract
The improvement of the survival of pediatric cancer patients is due to the development of complex therapy, especially of chemotherapy. Increased dose intensity of chemotherapy results in a better treatment outcome [1–5]. However, chemotherapy-associated life-threatening bacterial and fungal infections and mortality have remained a great problem. The risk of infection is directly related to the degree and duration of neutropenia [6]. The patient with neutropenic fever needs hospitalization and antibiotics, the quality of life is made worse, the costs of treatment are increased, and there is a delay in chemotherapy or dose reduction.
