A 42-year-old woman was referred to us for the treatment of relapsed Philadelphia-positive acute lymphoblastic leukemia (Ph+ALL), which had been maintained in complete remission for seven years after an allogeneic bone marrow transplantation (allo-BMT) from an unrelated donor. She received remission-reinduction chemotherapy combined with imatinib mesylate. After the documentation of the molecular remission of Ph+ALL, she underwent the second allo-BMT from another unrelated donor. GVHD prophylaxis consisted of tacrolimus (TAC) and short-term methotrexate. On day 21, she suddenly suffered from an intermittent severe, cramp-like pain in the right lower limb. The typical pain profile and exclusion of other causative diseases suggested calcineurin-inhibitor induced pain syndrome (CIPS) as a possible cause of pain. The pain was gradually relieved after discontinuation of TAC and administration of several analgesic drugs. CIPS is rarely seen following allogeneic stem cell transplantation (allo-SCT); only three cases have been so far reported to our knowledge. Thus, physicians should be alert to this complication in patients receiving allo-SCT.

Allogeneic stem cell transplantation (alloSCT) has been used in the hopes of harnessing the curative potential of the graft-versus-myeloma effect. This study examines the long-term outcomes of a large cohort of patients with myeloma who were treated with myeloablative alloSCT at a single center. Comparisons are made with those who were treated with autologous stem cell transplantation (ASCT). Between January 1989 and February 2002, 158 patients age<or=55 years underwent SCT for myeloma. Seventy-two patients underwent myeloablative alloSCT (58 related; 14 unrelated), whereas 86 patients underwent ASCT. Most patients received single-agent high dose dexamethasone or VAD (vincristine, adriamycin, dexamethasone) therapy pre-SCT. Conditioning regimens were melphalan-based for all ASCT patients, whereas the alloSCT patients received melphalan-based (70%), total-body irradiation (TBI)-based (18%), or other (13%). Patients who underwent alloSCT were younger, had a higher Durie-Salmon stage disease, and a shorter median time from diagnosis to transplant. Myeloma subtypes were similar between groups. Other pre-SCT (BMT) characteristics were similar except that ASCT patients had a higher proportion of cases that received palliative radiotherapy pre-SCT. Disease response pre-SCT was similar. At last follow-up, 61 of 158 patients are alive with a median follow-up of 88.4 months (range: 35.5-208.5). The overall survival (OS) of the alloSCT cohort was 48.1% at 5 years and 39.9% at 10 years compared to 46.2% at 5 years and 30.8% at 10 years for the ASCT cohort (P=.94). The event-free survival of the alloSCT cohort was 33.3% at 5 years and 31.4% at 10 years compared to 32.9% and 15.2%for the ASCT cohort (P=.64). Treatment-related mortality (TRM) at 1 year was 22% for the alloSCT cohort and 14% in the ASCT cohort (P=.21). Cumulative incidence of grade II-IV acute graft-versus-host disease (aGVHD) was 72% and the cumulative incidence of chronic GVHD (cGVHD) was 68% at 2 years. Neither aGVHD nor cGVHD had an influence on OS or event-free survival, although 5 of 14 patients who have received donor lymphocyte infusions (DLI) have had disease response. The risk of relapse was reduced in those who developed aGVHD (P=.02) but not cGVHD (P=.23). In conclusion, although there are patient who are alive without disease>10 years post myeloablative alloSCT, similarly there are long-term survivors post-ASCT. Myeloablative alloSCT should not be considered standard treatment, and should only be considered in the context of a clinical trial.

Over the past decade, relevant improvements and refinements have significantly changed the indications, technique and results obtained with allogeneic hematopoietic SCT (HSCT) in childhood. A fundamental turning point in the history of allogeneic HSCT is represented by the use of placental blood, which was first employed in 1988 in a patient with Fanconi anemia, successfully transplanted with cord blood cells from an HLA-identical sibling. Since then, thousands of children were given an allograft of cord blood-derived hematopoietic progenitors, mainly from an unrelated donor. This large clinical experience has documented that, as compared with BMT, cord blood transplantation (CBT) is associated with reduced incidence and severity of GvHD. The outcome of recipients given unrelated CBT has been reported to be at least as good as that of patients transplanted with either BM or peripheral blood mobilized cells of an unrelated volunteer. Another emerging strategy of HSCT is that of using HLA-partially matched relatives as donors of hematopoietic progenitors. The infusion of a huge number of positively in vitro-selected CD34+ cells, with the concomitant removal of T cells, has been demonstrated to permit sustained engraftment of donor hematopoiesis, without the occurrence of GvHD in the majority of patients transplanted from an HLA-disparate relative. In adults given this type of transplantation, the most favorable results have been reported for AMLs and when the donor displays alloreactivity of natural killer cells. It remains to be definitively proved whether these findings documented in adults maintain their value in pediatric patients transplanted from an HLA-disparate family donor. Finally, the last few years have witnessed the emergence of approaches of adoptive cell therapy aimed at optimizing the results of allograft through strategies able to reinforce immune competence against pathogens, as well as against tumor cells, or at modulating donor T-cell alloreactivity.

Previously, we reported the syndrome of inappropriate secretion of antidiuretic hormone (SIADH) as an underestimated complication associated with SCT. In the present report, we analyzed detailed data on a larger number of patients with SIADH following SCT and found different SIADH clinical features following cord blood SCT (CBSCT) and BMT/PBSCT. The median onset of SIADH following CBSCT and BMT/PBSCT was 19 and 46 days after SCT, respectively, and the median numbers of WBC at the onset of SIADH were 1.0 and 3.1 x 10(9)/l, respectively. Furthermore, severe symptoms such as seizures, somnolence and rigidity of limbs were observed only in patients with CBSCT (8/15 vs 0/10). These differences were statistically significant (P<0.01). Although the precise basis for SIADH following SCT still remains unknown, the different features of SIADH observed following CBSCT and BMT/PBSCT may provide important clues to the disease mechanism following SCT. Additionally, we confirmed our previous results that patients with SIADH showed a higher overall survival and event-free survival rates. However, we first suggested that they had some neurological disorders and that neurological sequelae such as developmental delay and seizures would consequently occur.

In total, 124 adult patients in remission after allogeneic hematopoietic SCT (HSCT) participated in a cross-sectional study to assess health-related quality of life (HRQL). Assessment of HRQL was carried out using two questionnaires: the (EORTC QLQ-C30) and the Functional Assessment of Cancer Therapy (FACT) with specific modules for BMT (FACT-BMT). Transplanted patients differed from healthy controls in many HRQL-related dimensions in the EORTC QLQ-C30: social functioning 73.4 versus 85.8, P<0.0001; role functioning 74.6 versus 83.3, P<0.004; physical functioning 83.9 versus 89.9, P<0.001; emotional functioning 72.2 versus 82.8, P<0.0001 but were not significant for global HRQL 71.2 versus 75.3, P<0.03. In total, 60% of the patients returned to work after HSCT; 31% part time and 29% full time. Age at HSCT and employment status were significantly associated with HRQL. Other factors such as disease and disease stage and especially the occurrence of late complications did not impact the perception of HRQL. This study suggests that the perception of HRQL after HSCT differs from the general population. Issues to increase work-related capabilities and improve social support need to be addressed.

Observational databases, such as those maintained by the Center for International Blood and Marrow Transplant Research (CIBMTR) and the European Blood and Marrow Transplant Group (EBMT), play an important role in facilitating research into hematopoietic SCT (HCT) outcomes. The CIBMTR maintains a large database of the outcome of BMTs performed in 450 centers in 47 countries, including information on 240,000 transplant recipients and adding information on about 14,000 new transplants per year. The database has data for 9000 survivors followed for 10 or more years. The database may facilitate the understanding of outcomes by addressing questions difficult to answer through clinical trials. Clinical databases may also aid the development of optimal designs for prospective clinical trials. Use of the CIBMTR database for trial design and monitoring is an integral part of the US Blood and Marrow Transplant Clinical Trials Network (BMT CTN). The establishment of international outcomes registries was an important component of advances in HCT over the past three decades. Future progress will be further enhanced by inter-registry collaboration through the Worldwide Blood and Marrow Transplant Group (WBMT).

The first hematology department in Morocco was created in Casablanca in 1980 and it is still the only public facility where adult patients can be treated for hematological diseases. Two other units treat pediatric hematological disorders and cancer. Some patients are treated in private clinics located primarily in Casablanca and Rabat. The public hospitals have very limited resources and rely heavily on nongovernmental organizations (NGOs) for the care of these patients. The NGOs have also played an important role in developing successful cooperative programs with hospitals and groups in Europe and the United States. Till 2004, all patients who needed BMT and could afford the cost went to Europe. In 2004, SCT was initiated in Casablanca, with a four-bed ward set up and properly equipped. By May 2007, 27 patients have received autologous PBSCs. With 15 patients in continuous CR, the program is considered a success so far. The development of allogeneic transplantation in Morocco planned in the current year is also considered a real challenge.

Stem cell transplantation is curative in a number of otherwise fatal hematological diseases. In Pakistan, SCT was started in October 1995 at Dr Ziauddin Hospital by Dr Tahir Shamsi and his team. The first case was of a young man suffering from AML. In 1999, allogeneic BMT was started at Bismillah Taqee Institute of Health Sciences and Blood Diseases Centre, Karachi. In 2001, the Armed Forces Bone Marrow Transplant Centre, started functioning. Since then, over 350 allogeneic stem cell transplants have been carried out in these latter two centers. Another 50 autologous procedures were carried out in all centers. In 2004, a third center started transplants at the Aga Khan Hospital. The main indications for transplant are aplastic anemia, beta-thalassemia major and hematological malignancies. HLA-identical sibling donors provide stem cells for the recipient. In 70% of cases, a matched donor is identified. In sharp contrast to the rest of the world, the majority of transplants are allogeneic, donor-recipient pairs are CMV positive and fungal infection, tuberculosis and malaria are particular problems. The early results are promising, with transplant-related mortality reported to be 10-20%, whereas long-term survival is reported to be 78, 72 and 49% in aplastic anemia, beta-thalassemia major and leukemia, respectively. Financial constraints, poor socioeconomic status, poor transfusion services, trained human resources and difficulty in keeping pace with technological advances are major hurdles in the growth of transplant medicine. Government support is badly needed to strengthen existing facilities and to develop more centers.

In Vietnam, the first three cases of Allo-BMT were successfully performed in 1995 at the Blood Transfusion and Hematology Hospital (BT-H) of Ho Chi Minh City. Donors were HLA fully matched siblings (HLA-A, HLA-B and HLA-DRB1). The patients were a 26-year-old man with CML in chronic phase (CP), a 12-year-old woman with beta-thalassemia/Hb E and a 9-year-old girl with beta-thalassemia/Hb E. All patients were engrafted with the median time to recover ANC>0.5 x 10(9)/l, and platelet count >20 x 10(9)/l was 16 and 38 days. At 12 years after transplantation, all three patients are alive and well. Today, Vietnam has five SCT centers; in the north, there are three centers: 108 Military Hospital, Pediatric Institute and Blood transfusion and Hematology Institute; in the middle of Vietnam is Hue Hospital and in the south, the BT-H Hospital of Ho Chi Minh City. Until now, 65 patients have had SCT in Vietnam; among them, 52 patients had SCT at the BT-H Hospital, Ho Chi Minh City. Because of no connection of data between different SCT centers, we present here only the results performed at the BT-H Hospital, Ho Chi Minh City. With Allo-SCT we performed 19 cases with 3 procedures: BMT (4 cases), PBSC (6 cases) and cord blood transplantation (9 cases); patients were diagnosed with AML (n=7), ALL (n=1), CML (n=5) and beta-thalassemia (n=6). Following transplantation, 7 patients (36.84%) relapsed, 12 (63.16%) remained alive and overall survival times: 6.81+/-1.35 years, disease-free survival times: 6.69+/-1.4 years (range 0.5-12 years). With Auto-SCT: since November 1996, we have performed 33 cases of autologous PBSC transplantation consisting of without cryopreservation (24 cases) and with cryopreservation (9 cases); patients were diagnosed with AML in CR1 (n=21), ALL in CR1 (n=6), CML in CP (n=5) and non-Hodgkin's lymphoma in CR1 (n=1). The median age of the patients was 35 years (range 18-46). The median time to recover ANC >0.5 x 10(9)/l and platelet count >20 x 10(9)/l was 14 days (range 9-25 days) and 35 days (range 9-120 days). Following transplantation, 18 patients (54.50%) relapsed, 15 (45.45%) remained alive and overall survival times: 5.74+/-0.82 years and disease-free survival times: 5.48+/-0.92 years. There was no statistically significant difference of overall survival and disease-free survival between Allo-SCT and Auto-SCT procedures (P>0.05). These preliminary data suggest that HSCTs have been used as one of the standard treatments for hematological diseases and malignancies in Vietnam and that cord blood is an alternative source of hematopoietic stem cells for allogeneic transplantation in children.

Bone marrow and stem cell transplantation in Jordan has been performed since the 1990s, but the first comprehensive program was established at King Hussein Cancer Center (KHCC) in March 2003. The program, in addition to other health care institutions in Amman, serves approximately 5.6 million Jordanians. Also, we treat several patients per year from neighboring Arab countries. The program at KHCC performs an average of 80 transplants per year. During the past 4 years 320 patients received transplants at KHCC; 26% of them received an autologous graft and 74% allogeneic grafts. Of the allogeneic grafts 91% were taken from matched family members, 6.7% were haploidentical from one of the parents, and 2.3% were from an unrelated donor or umbilical cord blood. The actuarial overall survival among all patients has been around 65%. The most common indication for transplantation at KHCC was leukemia/MDS followed by benign nonmalignant hematological/immune deficiency/metabolic disorders, with thalassemia major being the most common among this group. The cost of SCT is variable and depends on many factors including the type of transplant and the attending post-transplant complications. The average charge for autologous transplant (both adults and pediatrics) is 24,695 JD (one JD equals 1.42 USD), and the average charge for allogeneic transplant (both adults and pediatrics) excluding haploidentical transplant is 46,787 JD. We have not noticed any peculiar patterns of complications following BMT; however, we have seen a high incidence of chronic GVHD following minitransplant with fludarabine and single-dose TBI (Seattle protocol). At the inception of the program, invasive fungal infection mainly related to building construction, and central line complications were significant. Measures implemented to control such complications were successful to a large extent. We report our results to the EBMT group and we are accredited as an unrelated transplantation center. Although from a young program, our group has presented abstracts to international conferences.
