Abstract:

To analyze the effect of a splenectomy on pancytopenia after a peripheral blood stem cell transplantation (PBSCT) in chronic myeloid leukemia (CML) patients. Three CML patients diagnosed with splenomegaly in our department from 2002 to 2006 received a splenectomy after PBSCT. Patient 1, a 42-year-old male in chronic phase (CP), received an HLA-identical sibling allo-PBSCT. Patient 2, a 28-year-old female in aggressive phase (AP), received a PBSCT from her twin. Patient 3, a 26-year-old male in chronic phase (CP), received a PBSCT from an unrelated donor. The conditioning regimen included busulfan and cyclophosphamide (BU/CY2). Patients 1, 2, and 3 received splenectomies on days 168, 51, and 114, respectively. Bcr-abl transcripts were detected using the polymerase chain reaction (PCR). Chimerism was documented by PCR amplification of a variable number of tandem repeat (VNTR) polymorphrisms. Neither metrisone (2 mg/kg/day for 7 days), mycophenolic acid (MMF) (0.5 g twice daily for 1 month), high-dose γ-globulin (0.4 g/kg/day for 5 days), granulocyte colony-stimulating factor (G-CSF) therapy, nor erythropoietin (EPO) therapy had produced post-PBSCT hematopoiesis recovery. Patients 1 and 2 had 5% Ph-positive chromosomes while patient 3 exhibited graft-versus-host disease (GVHD). After receiving the splenectomy, all three had a rapid hematopoeitic recovery with no evidence of Ph-positive chromosomes, and patients 1 and 3 showed complete donor chimerism (CDC). Patient 1 developed chronic GVHD (cGVHD) on day 210 postsplenectomy that was treated successfully with prednisone. Patient 2 had acute GVHD on day 55 that was treated successfully with dexamethasone (10 mg), administered intravenously once a day for 3 days with good clinical response. To date, patients 1, 2, and 3 have survived postprocedure for 85, 49, and 25 months, respectively. Splenectomy is an effective option for the patients who have pancytopenia after PBSCT and the patients recovered a good graft function after splenectomy without procedure-related complication and with long-time survival. GVHD can develop in both allo-PBSCT and syngeneic PBSCT. A splenectomy after PBSCT may increase the risk of GVHD, enhance the effect of graft versus leukemia (GVL), promote CDC formation.

More about this publication?
  • Cell Transplantation publishes original, peer-reviewed research and review articles on the subject of cell transplantation and its application to human diseases. To ensure high-quality contributions from all areas of transplantation, separate section editors and editorial boards have been established. Articles deal with a wide range of topics including physiological, medical, preclinical, tissue engineering, and device-oriented aspects of transplantation of nervous system, endocrine, growth factor-secreting, bone marrow, epithelial, endothelial, and genetically engineered cells, among others. Basic clinical studies and immunological research papers are also featured. To provide complete coverage of this revolutionary field, Cell Transplantation will report on relevant technological advances, and ethical and regulatory considerations of cell transplants. Cell Transplantation is now an Open Access journal starting with volume 18 in 2009, and therefore there will be an inexpensive publication charge, which is dependent on the number of pages, in addition to the charge for color figures. This will allow work to be disseminated to a wider audience and also entitle the corresponding author to a free PDF, as well as prepublication of an unedited version of the manuscript.
