Influence of related factors on the first results of peripheral blood hematopoietic stem cell mobilization in lymphoma patients
The effect of hematopoietic stem cell collection is affected by a variety of factors, but the clear influencing factors have not yet been determined. It is necessary to continuously explore the risk factors that may affect the collection of hematopoietic stem cells.
To investigate the influence of related factors on the first results of hematopoietic stem cell mobilization in peripheral blood of 50 patients with malignant lymphoma, and to explore the relationship between results and hematopoietic reconstruction after transplantation.
Totally 50 lymphoma patients undergoing autologous peripheral blood hematopoietic stem cell transplantation from January 2015 to January 2020 were included in this study so as to analyze the age, stage, bone marrow invasion, recurrence, radiotherapy, granulocyte colony-stimulating factor duration, chemotherapy duration and other factors on the first hematopoietic stem cell collection, and to explore the relationship of collection results with neutrophile granulocyte and platelet implantation.
The number of chemotherapy courses was negatively correlated with the collected CD34+ cell count. The results of hematopoietic stem cell collection were poor in patients with recurrence before transplantation, and among the radiotherapy patients, mobilization failure was relatively high, with a failure rate of 88.9%. Radiotherapy had a negative effect on hematopoietic stem cell collection. The higher the CD34+ cell count, the faster the neutrophile granulocyte implantation. However, the effect on post-transplantation platelet implantation was not so significant, but there was a trend. There was no difference in the number of CD34+ cells collected between granulocyte colony-stimulating factor duration of 1-5 days and granulocyte colony-stimulating factor duration of over 5 days. The results concluded that in lymphoma patients, excessive chemotherapy, recurrence and radiotherapy experience will obviously cause damage to hematopoietic stem cells. Radiotherapy should be performed after hematopoietic stem cell collection to avoid damage to hematopoietic stem cells.
