Evaluate the Efficacy and Safety of the Prophylactic Use of PEG-rhG-CSF in Children With Hematological Malignancies
Study Details
Study Description
Brief Summary
The incidence of infectious complications in hematological malignancies is higher than that in children with solid tumors, which may be related to the type and dose intensity of chemotherapy regimens used in hematological tumors. The treatment of childhood cancer has changed in the past few decades: intensive treatment and good supportive treatment can improve the 5-year survival rate of children. The aim of this study was to evaluate the efficacy and safety of prophylactic use of pegylated recombinant human granulocyte colony-stimulating factor (PEG-rhG-CSF) after chemotherapy in children with hematological malignancies.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: PEG-rhG-CSF group Patients received subcutaneous injection of PEG-rhG-CSF(Jinyouli®)24~72 hours after the end of chemotherapy, 100µg/kg, once in each chemotherapy cycle. |
Drug: PEG-rhG-CSF group
Patients received a single dose of 100 ug/kg of PEG-rhG-CSF（Jinyouli®）, on the basis of actual body weight. Peg-rhG-CSF can be used prophylactically only when the interval between two chemotherapy regimens is no less than 12 days.
|
| Active Comparator: rhG-CSF group Patients received subcutaneous injection of rhG-CSF 24~72 hours after the end of chemotherapy, 100µg/kg/d, and stop using it until the ANC value exceeds the lowest value for 2 consecutive days> 0.5×10^9/L. |
Drug: rhG-CSF group
Patients received 5μg/kg/d of rhG-CSF, on the basis of actual body weight.

Outcome Measures
Primary Outcome Measures
- Incidence of febrile neutropenia (FN) [From date of randomization until the date of the study completion, up to 24 weeks.]
ANC<0.5×10^9/L or ANC (0.5-0.9)×10^9/L, and predicted to drop to ≤0.5×10^9/L in the next 48 hours, and the oral cavity temperature is ≥38.3℃ or ≥38.0℃ for more than 1 hour.
Secondary Outcome Measures
- Duration of febrile neutropenia [From date of randomization until the date of the study completion, up to 24 weeks.]
Defined as days when the FN occurs to the time when FN disappears.
- Incidence and duration of grade IV neutropenia (ANC<0.5×10^9/L) [From date of randomization until the date of the study completion, up to 24 weeks.]
Grade IV neutropenia is defined as the absolute neutrophil count(ANC)<0.5×10^9/L; Duration of grade IV neutropenia is defined as days when the ANC<0.5×10^9/L occurs to the time when the ANC≥0.5×10^9/L
- Recovery time of grade IV neutropenia [From date of randomization until the date of the study completion, up to 24 weeks.]
Time from the first day of chemotherapy to ANC≥0.5×10^9/L
- Dynamic curve of absolute neutrophil count (ANC) [From date of randomization until the date of the study completion, up to 24 weeks.]
Dynamic changes of ANC after chemotherapy
- Hospital stay [From date of randomization until the date of the study completion, up to 24 weeks.]
Number of days the patient was hospitalized
- Incidence of infection [From date of randomization until the date of the study completion, up to 24 weeks.]
Incidence of various infections
- Dose adjustment of chemotherapy or delay of chemotherapy [From date of randomization until the date of the study completion, up to 24 weeks.]
Dose adjustment of chemotherapy is defined as incidence of the reduction of planned dose of chemotherapy；Chemotherapy delay is defined as the delay in starting the next planned chemotherapy for more than 3 days.
