Marrow transplantation is effective treatment for a number of haematological diseases in patients under the age of 50 who have an HLA-identical sibling donor. It is generally successful when used early in the treatment of aplastic anaemia. It is the only treatment that offers long-term disease-free survival for patients with acute leukaemia who have relapsed at least once, with 10-30 per cent apparent cures. Although still somewhat controversial, it appears also to be the treatment of choice for patients with acute non-lymphoblastic leukaemia in first chemotherapy induced remission and for those with chronic myelogenous leukaemia in the chronic phase since approximately 50-60 per cent of these patients are surviving after marrow transplantation in complete remission, apparently cured. Marrow grafting is the only effective treatment for many patients with inherited immunological-deficiency diseases and certain genetic storage diseases. It is being explored for the therapy of patients with lymphoma, Hodgkin's disease, multiple myeloma, small-cell lung cancer, testicular cancer, ovarian cancer and genetic disorders of haematopoiesis. Cures of congenital Fanconi anaemia, Blackfan-Diamond anaemia, osteopetrosis, and paroxysmal nocturnal haemoglobinuria have been achieved by marrow grafting. Genetic disorders associated with haemolytic anaemia and cyclic neutropenia have been cured by marrow grafting in animals. Target disorders for marrow transplantation in humans are thalassaemia major and sickle cell disease, and, indeed, a first successful transplant for treatment of thalassaemia major has recently been described (Thomas et al, 1982). Marrow transplantation has been limited by the fact that many patients do not have HLA-identical siblings and very few have monozygotic twins. The Seattle team has now explored the use of less well-matched family member donors in more than 80 patients with leukaemia. These donors share one HLA haplotype genetically with the patient and are phenotypically identical at two of the three major HLA loci on the other HLA haplotype (Clift et al, 1979). Overall, the post-transplant survival appears more a reflection of the type and stage of the leukaemia than of the marrow donor. Patients with leukaemia grafted in relapse have a projected survival of 20-30 per cent and those transplanted in remission of 50 per cent. The incidence and severity of GVHD may not be significantly different from that of patients given HLA-identical sibling marrow grafts.(ABSTRACT TRUNCATED AT 400 WORDS)

Transfer of drug resistance genes into hematopoietic stem cells (HSCs) has promise for the treatment of a variety of inherited, that is, X-linked severe combined immune deficiency, adenosine deaminase deficiency, thalassemia, and acquired disorders, that is, breast cancer, lymphomas, brain tumors, and testicular cancer. Drug resistance genes are transferred into HSCs either for providing myeloprotection against chemotherapy-induced myelosuppression or for selecting HSCs that are concomitantly transduced with another gene for correction of an inherited disorder. In this review, we describe ongoing experimental approaches, observations from clinical trials, and safety concerns related to the drug resistance gene transfer.

From March 1991 through 31st December 2007, 2042 patients underwent stem cell transplantation at the Hematology-Oncology and Stem Cell Transplantation Research Center, affiliated to Tehran University of Medical Sciences. These transplantations included 1405 allogeneic stem cell transplantation, 624 autologous stem cell transplantation, and 13 syngeneic stem cell transplantation. Stem cell transplantation was performed for various diseases including acute myelogenous leukemia, acute lymphoblastic leukemia, chronic myelogenous leukemia, chronic lymphoblastic leukemia, thalassemia major, sickle cell thalassemia, sickle cell disease, multiple myeloma, myelodysplasia, mucopolysaccharidosis, paroxysmal nocturnal hemoglobinuria, non-Hodgkin's lymphoma, Hodgkin's disease, severe aplastic anemia, plasma cell leukemia, Niemann-Pick disease, Fanconi anemia, severe combine immunodeficiency, congenital neutropenia, leukocyte adhesion deficiencies, Chediak-Higashi syndrome, osteopetrosis, histiocytosis X, Hurler syndrome, amyloidosis, systemic sclerosis, breast cancer, Ewing's sarcoma, testicular cancer, germ cell tumors, neuroblastoma, medulloblastoma, renal cell carcinoma, nasopharyngeal carcinoma, ovarian cancer, Wilms' tumor, rhabdomyosarcoma, pancreatoblastoma, and multiple sclerosis. We had 105 cellular therapies for postmyocardial infarction, multiple sclerosis, cirrhosis, head of femur necrosis, and renal cell carcinoma. About 30 patients were retransplanted in this center. About 74.9% of the patients (1530 of 2042) remained alive between one to 168 months after stem cell transplantation. Nearly 25.1% (512 of 2042) of our patients died after stem cell transplantation. The causes of deaths were relapse, infections, hemorrhagic cystitis, graft versus host disease, and others.
