Evaluation of the Application of PEGylated Recombinant Human Granulocyte Stimulating Factor Injection (PEG-rhG-CSF) in Chemotherapy of Elderly Lymphoma Patients

Multi-center, Open, One-arm Clinical Study Evaluating the Efficacy and Safety of Pegylated Recombinant Human Granulocyte-stimulating Factor Injection (PEG-rhG-CSF) in Preventing Neutropenia in Elderly Patients With Lymphoma After Chemotherapy

A multicenter, open, one-arm clinical study evaluated the efficacy and safety of Jinyouli in preventing neutropenia after chemotherapy in elderly lymphoma patients who met the criteria for admission. Chemotherapy regimen: The investigator selected according to the specific condition the corresponding standard chemotherapy regimen, the chemotherapy regimen used, FN risk ≥ 20%, or 10% < FN risk < 20% with at least one high risk factor for FN, from the first cycle of chemotherapy, 24-72 after chemotherapy hour subcutaneous injection of Jinyouli.
