PEG-rhG-CSF Compared With rhG-CSF in Lymphoma Patients After Autologous Hematopoietic Stem Cell Transplantation

The purpose of the study is to evaluate the efficacy and safety of PEG-rhG-CSF compared with rhG-CSF on the recovery of hematopoietic function after autologous stem cell transplantation in patients with lymphoma.

The purpose of the study is to evaluate the efficacy and safety of PEG-rhG-CSF compared with rhG-CSF in lymphoma patients after autologous hematopoietic stem cell transplantation. Eligible patients were randomly assigned to PEG-rhG-CSF group or rhG-CSF group. Patients in PEG-rhG-CSF group received PEG-rhG-CSF day +1 after transplantation with a dose of 6 mg. Patients in rhG-CSF group received rhG-CSF day +1 after transplantation with a dose of 5μg/kg once per day until the count of neutrophil\>0.5×10\^9 /L.

Eligibility Criteria:
Inclusion Criteria:

1. Patients with age between 18 and 65 years;
2. hematopoietic stem cell transplantation for the first time;
3. Lymphoma patients with the requirement for autologous;
4. ECOG score ≤2;
5. Estimated survival time \> 3 months;
6. All acute toxicity caused by previous chemotherapy or treatment has been restored; 7.1) The absolute value of neutrophils (\>1.5×10\^9/L); Hemoglobin (\> 90 g/L); 2)Upper Limit Normal (ULN) or creatinine clearance rate (\>40 mL/min) of serum creatinine (\<1.5 times normal value upper limit) (estimated by Cockcroft-Gault formula); Serum total bilirubin \< 1.5 times ULN; Aspartate Aminotransferase (AST), Alanine Aminotransferase (ALT) = 2.5 times ULN; 7) Coagulation function: International Normalized Ratio (INR) = 1.5 times ULN; Prothrombin Time (PT), Activated Partial Thromboplastin Time (APTT) = 1.5 times ULN (unless the subject is receiving anticoagulant therapy and PT and APTT are using anticoagulant therapy at screening time). Within the expected range; Thyrotropin (TSH) or free thyroxine (FT4) or free triiodothyronine (FT3) were all within the normal range (+10%);
