Stem Cell Mobilization and Harvesting Failure in Case of Heavily Pretreated Patients


Background: High-dose chemotherapy and autologous stem cell transplantation have become a standard curative treatment in various hematologic malignancies. Many factors can affect the success of mobilization and hematopoietic stem cell harvesting.

Aim: The aim of this study was to analyze factors that lead to mobilization failure.

Material and Methods: We conducted a retrospective study on 19 patients with failure of stem cell harvesting. All patients were administered high doses of GCS-F (filgrastim, 15 μg/kg/day) and 0.24 mg/kg of plerixafor on day +5 or +10 of harvesting.

Results: The median age of the study population was 51 years (range 35–67) and 52.6% (n = 10) were males. The study group included 4 (21%) subjects with multiple myeloma, 6 (31.5%) with Hodgkin lymphoma, 8 cases (42.1%) with non-Hodgkin lymphoma and 1 patient with chronic lymphocytic leukemia. Each patient received 2.78 (range 1–5) lines of chemotherapy, administered in 11.57 (range 2 to over 20) cycles of treatment.

Conclusion: In hematologic malignancies it is very important to collect stem cells in time, in order to reduce mobilization failure. As we have shown in our studied cases, multiple lines of polychemotherapy with or without radiotherapy lead to mobilization failure.

Post Autologous Stem Cell Transplantation Complication Management in Case of Malignant Lymphoma Patients


Introduction: Autologous hematopoietic stem cell transplantation (ASCT) represents a standard therapy in the management of hematologic malignancies such as malignant lymphomas and has used for approximately three decades. The aim of this study was to determine the occurring post-ASCT complications and their impact on the patients’ recovery for a better management.

Material and methods: An observational retrospective study was performed during a five-year period between 2012 and 2017, involving 58 classical Hodgkin lymphoma and 36 non-Hodgkin lymphoma patients, who underwent ASCT in the Bone Marrow Transplantation Unit of Tîrgu Mureş. The main analyzed complications were: infections, bleeding, hydroelectrolytic disorders, and hypoalbuminemia.

Results: After data analysis we found that 17 patients (18%) presented microbiologically confirmed infection, 10 patients (11%) presented clinically non-significant bleeding, 39 patients (42%) presented electrolyte disorders, and 33 patients (36%) presented hypoalbuminemia, obtaining a positive correlation between the rate of adverse events after ASCT with age (r = 0.9914, p = 0.0009) and the average hospitalization period (r = 1, p <0.00001).

Conclusions: The identification of adverse events and their correlation with the patients’ clinical outcome can lead to better patient management and a faster recovery after ASCT.

The Evolution of Intracardiac Hemodynamics Post Autologous Stem Cell Transplant in a Case of Multiple Myeloma Associated with Severe Tricuspid and Mitral Valve Insufficiency


Stem cells are undifferentiated cells that can divide and become differentiated. Hematopoietic stem cells cannot transform into new stem cells such as cardiomyocytes or new heart valves, but they act through paracrine effects, by secreting cytokines and growth factors that lead to an increase in contractility and overall improved function. In this case report, we present how autologous stem cell transplantation can bring two major benefits: the first refers to hematological malignancy and the second is about the improvement of the heart condition. We present the case of a 60-year-old patient diagnosed with multiple myeloma suffering from a bi-valve severe condition in which autologous stem cell transplantation led to the remission of the patient’s malignant disease and also improved the heart function.

Difficulties of Mobilization and Harvesting of Hematopoietic Stem Cells in Heavily Pre-Treated Patients


This study presents a new method of combined growth factor mobilization with increased dose (15 μg/kg) of filgrastim and standard mono dose of plerixafor in subjects with multiple myeloma, Hodgkin or non-Hodgkin lymphoma. Efficient mobilization is a key factor in the treatment of this group of patients, because autologous transplantation can be performed in cases in which we succeed to obtain a minimally sufficient number of stem cells. Autologous stem cell transplantation is included in the current standard treatment of multiple myeloma and in the relapsed cases of lymphomas.
