Abstract
Background: Neuroblastoma (NB) is the most common extracranial solid tumor in pediatric. In highrisk NB patients, the 5-year overall survival rate (OS) remains a stark < 50 % with conventional therapies. Autologous hematopoietic stem cell transplantation with high dose chemotherapies was used in poor prognosis and high-risk patients.Today, Plerixafor is used to increase stem cells mobilization in patients who are candidates for autologous transplantation.
Objective: This study examined safety and efficacy Plerixafor is administered as a subcutaneous injection in pediatric NB patients for stem cell mobilization STUDY DESIGN: A cohort of 19 pediatric neuroblastoma (NB) patients underwent autologous hematopoietic stem cell transplantation (HSCT) between February 2017 and April 2019, receiving G-CSF mobilization only. Subsequently, 37 NB patients underwent HSCT between December 2019 and October 2023, receiving both G-CSF and plerixafor for mobilization (auto-HSCT).
Results: The final product CD34 cell dose /kg was evidently higher in combination group at 5.363 ± 4.243 vs. G-CSF group at 2.827 ± 3.586 × 106(P value= 0.001). Neutrophils and platelet engraftment were occurred sooner in combination group compared with G-CSF group. The 1-year overall survival (OS) rate for the G-CSF and G-CSF-and-plerixafor combination group was 70.8 % and 63.3 %, respectively (P = 0.874). No statistically significant difference in OS or disease-free survival (DFS) was observed between the two treatment groups.
Conclusion: The results show that plerixafor may be safe and effective in NB pediatric patients in routine clinical practice. It was well tolerated in NB patients and no specific side effects were observed. It was not associated with improved survival.
期刊介绍：
Transfusion and Apheresis Science brings comprehensive and up-to-date information to physicians and health care professionals involved in the rapidly changing fields of transfusion medicine, hemostasis and apheresis. The journal presents original articles relating to scientific and clinical studies in the areas of immunohematology, transfusion practice, bleeding and thrombotic disorders and both therapeutic and donor apheresis including hematopoietic stem cells. Topics covered include the collection and processing of blood, compatibility testing and guidelines for the use of blood products, as well as screening for and transmission of blood-borne diseases. All areas of apheresis - therapeutic and collection - are also addressed. We would like to specifically encourage allied health professionals in this area to submit manuscripts that relate to improved patient and donor care, technical aspects and educational issues.
Transfusion and Apheresis Science features a "Theme" section which includes, in each issue, a group of papers designed to review a specific topic of current importance in transfusion and hemostasis for the discussion of topical issues specific to apheresis and focuses on the operators'' viewpoint. Another section is "What''s Happening" which provides informal reporting of activities in the field. In addition, brief case reports and Letters to the Editor, as well as reviews of meetings and events of general interest, and a listing of recent patents make the journal a complete source of information for practitioners of transfusion, hemostasis and apheresis science. Immediate dissemination of important information is ensured by the commitment of Transfusion and Apheresis Science to rapid publication of both symposia and submitted papers.
