  • Between July 1987 and December 1992, we treated 22 patients with chronic myelogenous leukemia; 14 in the chronic phase and 8 with more advanced disease. All were received with allogeneic bone marrow transplantation from HLA-identical sibling donors after a total body irradiation(TBI) cyclophosphamide conditioning regimen. Patients were non-randomly assigned to either 1200 cGy/6fractions/3days (6 patients) or 1320 cGy/8 fractions/4days (16 patients) by dose of TBI. Of the 22 patients, 8 were prepared with cyclophosphamide alone, 14 were conditioned with additional adriamycin or daunorubicin. To prevent graft versus host disease, cyclosporine was given either alone or in conjunction with methotrexate. The actuarial survival and leukemic-free survival at four years were $58.5\%$ and $41.2\%$, respectively, and the relapse rate was $36\%$ among 22 patients. There was a statistically significant difference in survival between the patients in chronic phase and more advanced phase ($76\%\;vs\;33\%$, p=0.05). The relapse rate of patients receiving splenectomy was higher than that of patients receiving splenic irradiation ($50\%\;vs\;0\%$, p=0.04). We conclude that the probability of cure is highest if transplantation is performed while the patients remains in the chronic phase.

  • Purpose: Marrow stromal cells (MSCs) have been known for their potential to trans-differentiate into neural and glial cells in vitro and in vivo. To investigate the influence of the developing host environment on the survival and morphological and molecular differentiation, murine MSCs transplanted into the eye of Brazilian opossum (Monodelphis domestica). Methods: Enhanced green fluorescent protein (GFP) - expressing MSCs were transplanted into developing Brazilian opossums. Animals were allowed to survive for up to 4 weeks after transplantation, at which time the eyes were prepared for immunohistochemical analysis. Results: Some transplanted MSCs survived and showed morphological differentiation into neural cells with some processes within the host vitreous chamber. Some transplanted cells expressed class III ${\beta}$-tubulin (TuJ1, a marker for neuronal cells) or glial fibrillary acid protein (GFAP, a marker for glial cells) or Nestin (a marker for neural stem cells). In addition, some transplanted cells were located in ganglion cell layer but did not show morphological and molecular differentiation. Conclusions: Our result show that the most effective stage of development for transplantation into the retina was postnatal day 16, which retinas developmentally corresponded to postnatal day 4-5 days mouse retina based on cell differentiation and lamination patterns. The present findings suggest that the age of the host appears to play a key role in determining cell fate in vivo.

  • Purpose : In most cases, myelodysplastic syndrome(MDS) transforms into a more aggressive state or acute myelogenous leukemia; it's prognosis is very poor. It is believed that hematopoietic stem cell transplantation(HSCT) is the only curative treatment of MDS, but available data in children are very sparse. In this report, the short term outcome of HSCT in childhood MDS was analyzed. Methods : Ten children with MDS(CMMoL 5, RAEB 3, RAEBt 2) underwent HSCT(HLA-matched sibling transplantation 4, HLA-matched unrelated transplantation 4, cord blood transplantation 1, HLA-mismatched familial transplantation 1) between November 1995 and January 2001 at St. Mary's Hospital. Median follow-up duration was 11 months. Results : Engraftment was successful in all cases and 8 patients are alive without disease. Three cases of VOD were observed and improved without complication. Four cases of grade II and 1 case of grade III acute GVHD were observed and well controlled with treatment. Three patients relapsed after transplantation. One patient is alive without disease after cytoreduction with allogenic stem cell rescue and 2 patients died of relapse. Conclusion : HSCT is a curative strategy of MDS and the survival rate is relatively higher than that of adults. But there is an obvious need for more studies because of the small number of patients and the short duration of the follow-up.
