This phase II study (between October 2020 and March 2022) enrolled pediatric patients with solid tumors or NHL treated with high‐intensity chemotherapy and with grade ≥3 myelosuppression for at least 14 days during chemotherapy. Prophylactic PEG‐rhG‐CSF was given at 100 μg/kg body weight (maximum total dosage of 6 mg) once 24–48 h following chemotherapy for two cycles. The primary endpoint was the incidence of PEG‐rhG‐CSF‐related adverse events (AEs). The key secondary endpoints were the rates of grade 3/4 neutropenia and febrile neutropenia (FN).
