Furthermore, this clinical trial aims to:
1. Compare the efficacy of empirical antibiotic administration of Ciprofloxacin and Ceftazidime in pediatric malignancy patients with high-risk neutropenic fever.
2. Analyze the differences in clinical effectiveness between ceftazidime and ciprofloxacin antibiotics based on the duration of fever, duration of neutropenia, duration of hospitalization in high-risk neutropenic fever in children with hematological malignancies.
3. Compare the mortality of pediatric patients with high-risk neutropenic fever due to hematological malignancies who received empirical antibiotic therapy of ceftazidime and ciprofloxacin.
4. Compare antibiotic escalation decisions in pediatric patients with high-risk neutropenic fever due to hematological malignancies who received empirical antibiotic therapy of ceftazidime and ciprofloxacin.
