Background: Granulocyte transfusion therapy has been used as supportive care for patients with prolonged neutropenia after intensive chemotherapy or peripheral blood stem cell transplantation (PBSCT). Here, we investigated clinical factors of granulocyte transfusion therapy for neutropenic patients with infection to evaluate its efficacy and safety.
Methods: A retrospective analysis of 25 neutropenic patients treated with 99 granulocyte collection and granulocyte transfusion therapy from October 2011 to April 2016 at the National Cancer Center was conducted. Two groups, a count recovery group with a cut off of >1,000/μL and a no recovery group were compared and symptoms related with granulocyte transfusion were analyzed.
Results: Granulocyte collection and transfusions were performed in 99 procedures. After granulocyte transfusion therapy, 21 patients (84%) showed count recovery, whereas 4 patients (16%) had no response. Significant differences in pre-absolute neutrophil count (29/μL vs. 0/μL, P=0.048), duration of neutropenia before granulocyte transfusion (11 days vs. 26 days, P=0.011), and total number of granulocyte transfusion (2 times vs. 11 times, P=0.049) were observed between groups. Temporary symptoms related granulocyte transfusion were observed in seven patients (28%); however, all patients showed clinical improvement. The median of the single transfusion volume was 220 mL (200 to 397 mL) and the mean total granulocyte content was 4.92×1010.
Conclusion: Granulocyte transfusion therapy is safe and effective for patient with life threatening neutropenia and infection, also considerable for early onset trial for granulocyte transfusion.
