Abstract
BACKGROUND The umbilical cord blood bank at the Mexican Institute of Social Security (IMSS-CBB) was established in January 2005. This lead to the development of the UCB transplantation program. Herein, we describe the experience generated during these 13 years. STUDY DESIGN AND METHODS Donor selection, as well as UCB collection, processing, and banking were performed under good manufacturing practices and standard operating procedures. UCB units were thawed, processed, and released for transplantation based on HLA and nucleated cell content. RESULTS From January 2005-December 2017, 1,298 UCB units were banked; 164 of them were released for transplantation, and 118 UCB transplants were performed. Ninety-four transplants were performed in pediatric patients and 24 in adults. Sixty percent of them corresponded to patients with leukemia, 19% were patients with marrow failure, and the rest had immunodeficiency, hemoglobinopathy, metabolic disorders, or solid tumors. Engraftment was observed in 67 patients (57% of transplanted patients) and 64% of them were still alive when writing this article. In contrast, only 13 of the 51 (25%) non-engrafting patients were alive. At the time of writing this article, the disease-free survival rate was 37%, and the overall survival rate was 47%, with survival periods of 161-3,721 days. CONCLUSION The IMSS UCB banking and transplantation program has had a significant impact for many IMSS patients. The hematopoietic transplantation program at our institution has benefited from the use of UCB as a source of transplantable cells.

Abstract
Aim: This study examined how umbilical cord blood (UCB) use was portrayed in the English language North American popular press. Methods: Directed content analysis was conducted on 400 articles from 2007 to 2017 containing 'cord blood,' published by the most read Canadian and American news sources. Results: A total of 86.3% of the articles detailed UCB treatments and therapies, the majority of which align with clinical evidence. Some articles portrayed speculative/experimental therapies as efficacious. Public and private banking initiatives received substantial attention, and were portrayed diversely. Promotional narrative messaging was evident around private banking. Conclusion: Findings demonstrate the need for continual monitoring of the media portrayals of UCB as stem cell and transplantation research develops and as clinics continue to operate.

Abstract
Clinical use of umbilical cord blood (UCB) for novel indications in regenerative therapy continues to rise, however, whether new indications are proven is less clear. An updated systematic search of the literature, focusing only on controlled clinical studies, is needed to properly assess potential efficacy. After updating our systematic search to April 1, 2018 (PROSPERO protocol CRD42016040157), a total of 16 studies were identified that addressed the treatment of cerebral palsy (four studies), type 1 diabetes (three studies), and nine other novel potential indications where only a single controlled study was identified. In the four controlled studies of patients with cerebral palsy, three used allogeneic cells and reported greater improvement in motor-related scores at 1, 3 and 6 months compared with controls. The results were mixed for other scores at other time points, including additional measures of mental and motor function. One study of autologous UCB treatment reported an improvement in motor function scores at 12 months compared with controls. In the three controlled studies of type 1 diabetes, two studies used autologous cells whereas one used allogeneic cord blood cells to "educate" autologous lymphocytes. Taken together, there was no clear difference in HbA1c levels or daily insulin requirements between treated patients and controls. For the nine published reports with a single controlled study, eight used allogeneic UCB cells and seven infused mesenchymal stromal cells derived from UCB. All but one study reported benefit. Many other published reports that lack a control group were not included in our analysis. More controlled studies are needed that use similar approaches regarding cell source and outcome measures at similar time points. Pooled estimates of results from multiple studies will be essential as published studies remain modest in size. Patients should continue to be enrolled in clinical trials because there are no novel potential indications remain unproven.

Abstract
Umbilical cord blood (UCB) has become the focus of intense efforts to collect, screen and bank haematopoietic stem cells (HSCs) in hundreds of repositories around the world. UCB banking has developed through a broad spectrum of overlapping banking practices, sectors and institutional forms. Superficially at least, these sectors have been widely distinguished in bioethical and policy literature between notions of the 'public' and the 'private', the commons and the market respectively. Our purpose in this paper is to reflect more critically on these distinctions and to articulate the complex practical and hybrid nature of cord blood as a 'bio-object' that straddles binary conceptions of the blood economies. The paper draws upon Roberto Esposito's reflections on biopolitics and his attempt to transcend the dualistic polarisations of immunity and community, or the private and the public. We suggest that his thoughts on immunitary hospitality resonate with many of the actual features and realpolitik of a necessarily internationalised and globally distributed UCB 'immunitary regime'.

Abstract
BACKGROUND Hematopoietic stem cells have been used for over 50 years in the treatment of diverse diseases. Umbilical cord blood (UCB) has proved to be a viable source of hematopoietic stem cells for transplantation purposes. The aim was to report the contribution of the umbilical cord blood bank over the past 9 years, in the treatment of various diseases. METHODS Since 2005 the number of units of blood from the umbilical cord and their use for transplantation in diverse disease were analyzed. A selection of volunteer pregnant women in labor was performed. Umbilical cord blood was obtained from them, which underwent processing, cryopreservation and validation, as well as compatibility test before using for transplantation. RESULTS Ten thousand and ninety nine candidates to donation were assessed, from whom 2481 unit of UCB were collected. Of these, 893 unit were processed and cryopreserved for transplantation. In 65% of cases there was histocompatibility between the cord cell and the receptors. Transplantation was done in 87 patients, 67% had hematologic neoplasias, who have received 140 units of UCB in 102 transplants. This Bank of UCB ranks second in the world in productivity according to the rate of utility of units in transplantation (3.3%). CONCLUSIONS Our bank of UCB has been able to develop a cell line (hematopoietic stem cells) with international quality standards and has been beneficial for patients served by our institution with need of a transplant mainly in hemato-oncologic patients.

Abstract
In this study, a self-administered questionnaire was used to assess opinions about stem cell research and cord blood banking. Three attitudes were examined: willingness to accept cord blood banking, willingness to accept embryonic stem cell research, and religious belief system. A total of 90 Wayne State University students enrolled in the study in response to an invitation posted on a web page for the university. Sex distribution among study participants was 79 females and eight males; three declined to state their sex. Support for cord blood banking was high (> 70%) among students. Students over the age of 25 years of age were more (85%) positive than students 18 to 24 years old (57%). They prefered a public cord blood bank over a private cord blood bank. Atheist/agnostic or spiritual/not religious students (> 90%), Catholic students (78%) and Christian students (58%) support cord blood banking. Age, sex and religion seems influence the student's attitude towards stem cell research and cord blood banking.

Abstract
Although used mainly for transplantation of hematopoietic stem cells in the treatment of blood disorders, umbilical cord blood (UCB)-based therapies are now being used increasingly for novel applications in nonhematopoietic diseases and as a form of cellular regenerative therapy or immune modulation. We performed a systematic scoping review by searching Medline, EMBASE, and the Cochrane Library for published articles, and we searched www.clinicaltrials.com and the World Health Organization International Clinical Trials Registry Platform to describe the breadth of published studies and ongoing clinical activity in umbilical cord-based cellular therapy for regenerative therapy and immune modulation. The most commonly published area of expertise in the use of UCB-derived cellular transplantation for novel indications is for neurological disorders and this remains the most active area of study in ongoing registered trials. An increasingly broad range of disorders, however, are reflected in ongoing registered trials, which suggests greater activity, interest, and investment in UCB-derived cellular therapy. Interestingly, adult patients compose the majority of patients reported in published reports and registered ongoing clinical studies continue to enroll predominantly adult subjects. Geographically, Asian countries appear most active in UCB-derived cellular therapy and our analysis of ongoing studies suggests this trend will likely continue. Regular assessment of published and ongoing activity in UCB transplantation for emerging novel indications will be critical for informing UCB banking establishments and funding agencies to guide changes in banking practices related to emerging trends in cell therapy.

Abstract
Cord blood units are now routinely used as an alternative source of haematopoietic stem cells from unrelated donors for allogeneic transplantation. In France, cord blood units are collected in a network of more than 70 maternity hospitals in relationship with 11 public cord blood banks part of the Réseau Français de Sang Placentaire. Unrelated cord blood unit donation is an altruistic act, anonymous and free. Donors are selected on medical criteria. Then, only cord blood unit containing more than 100 × 10(7) total nucleated cells and more than 1.8 × 10(6) CD34+ cells are cryopreserved according to Réseau Français de Sang Placentaire recommendations. Cord blood units qualification will be completed by viral and functional testings and the clinical outcome of the newborn child 6 weeks after the collection. Since the last 5 years, cord blood banking growing in France in order to enhance the French registry of volunteer donors by increasing both the number and diversity of the donors listed and make available cord blood banking for transplantation.

Abstract
BACKGROUND Umbilical cord blood (UCB) represents an alternative source of stem cells for transplantation for the treatment of hematologic malignancies and genetic disorders. There is scarce information detailing cord blood bank (CBB) collection and transplantation activities from developing countries. We documented our experience at a public university hospital in northeast Mexico. STUDY DESIGN AND METHODS We carried out a retrospective and descriptive analysis of our CBB activity during an 8-year period from May 2002 to September 2010. Collection, processing, and cryopreservation of CB were carried out following standard operating procedures. The minimum volume and total nucleated cell (TNC) content for cryopreservation were 80 mL and 8.0 × 10(8) , respectively. RESULTS A total of 1256 UCB units were collected; 428 (34%) were banked and 828 (66%) were discarded. The main reason for exclusion was biologic: low volume and/or low number of TNC accounted for 84% of the total discarded units. Cryopreserved cord blood units (CBUs) had a median volume of 113.8 mL (range, 80-213.2 mL) and 13.0 × 10(8) (range, 8 × 10(8) -36.6 × 10(8) ) TNCs. Cell viability was 99.3% (88-100%). The median CD34+ cell content was 4.0 × 10(6) (0.46 × 10(6) -19.38 × 10(6) ). Sixteen units have been released for transplantation, leading to a utilization rate of 3.7%. CONCLUSION CBB demands considerable human and financial resources; it is then essential for centers at developing countries to share their experience, results, and databases to increase the probability of finding matching units for their patients. Efforts to create and maintain CBBs allow to offer this therapeutic option at an affordable cost.

Abstract
BACKGROUND/AIMS Thirty-one umbilical cord blood transplants performed in Western Australia were retrospectively examined in order to document local experience and relevant prognostic factors. Three cord units were from human leucocyte antigen-matched siblings and the remainder were unrelated single (n= 22) or double (n= 6) cord blood transplants. METHODS Twenty patients were transplanted for malignant conditions and 11 for non-malignant conditions. Cord units contained a median of 5.6 × 107 total nucleated cells/kg and 1.4 × 105 CD34+ cells/kg. Cumulative incidence of neutrophil engraftment was 76% at day 60. RESULTS Of those who did not engraft, two patients remain alive following subsequent allogeneic bone marrow transplant. There were no deaths caused by graft-versus-host disease. Overall survival at median follow up of 28 months was 62%. Two year overall survival was influenced by type of disease (non-malignant = 91 ± 9% vs malignant = 41 ± 13%, P= 0.005), total nucleated cell dose (>3.5 × 107/kg = 87 ± 9% vs <3.5 × 107/kg = 34 ± 15%, P= 0.01) and CD34 dose (>1.7 × 105/kg = 92% vs <1.7 × 105/kg = 46%, P= 0.04). Age and human leucocyte antigen match did not influence survival. Four relapses occurred, all of which were fatal. CONCLUSION Cord blood transplantation for malignant and non-malignant disease is practised in Western Australia and outcomes are satisfactory. Trends and techniques in cord blood transplantation in this state are comparable with those observed nationally and overseas. Although numbers are small, cell dose appears to be predictive of overall survival

Abstract
Umbilical cord blood (UCB) has been shown to be a suitable source of haematopoietic stem cells (HSCs) for haematopoietic reconstitution. An increase in the number of UCB transplants indicates an expansion of utility in a broad spectrum of disease conditions. Along with the advantages, UCB also has limitations, and hence several investigators are working to further optimize UCB for this use. Beyond haematopoietic transplantation, additional potential applications of UCB include immunotherapy, tissue engineering and regenerative medicine. UCB banking has improved with time largely due to involvement of professional organizations and their published standards. However, accreditation of these organizations remains voluntary, and in India three of ten banks are public with the remaining being private. Only one public and one private bank are American Association of Blood Banks (AABB) accredited in India. Government agencies need to provide regulatory and safety oversight, which is lacking in serveral countries. Public policy regarding UCB is in its infancy throughout most of the world. Ethical issues, including access to UCB banking and use as therapy for diseases other than haematological and metabolic disorders are in the early phase of trials and remain speculative.

Abstract
Abnormal lung function is a known risk factor for poor outcomes in the allogeneic hematopoietic stem cell transplantation (HSCT) population, although the specific causes of these abnormalities have not been well explored. There is limited data on the effect of cigarette smoking on transplantation outcomes. We conducted a retrospective observational cohort study of 845 consecutive patients age ≥ 18 years who underwent allogeneic HSCT at the Seattle Cancer Care Alliance/Fred Hutchinson Cancer Research Center. Smoking exposure was defined by quit time, smoking status (never, former, and current), and log(2)-transformed pack-years. The main outcomes were time to respiratory failure within 100 days of transplantation, relapse, and nonrelapse mortality. In multivariable analyses, a 2-fold increase in pack-years smoked was associated with an increased risk of early respiratory failure (hazard ratio [HR] 1.33, 95% confidence interval [CI] 1.09 to 1.64, P = .006). This association was observed independent of pretransplantation lung function. A 2-fold increase in pack-years smoked was associated with an increased risk of relapse, but this finding was not statistically significant (HR 1.16, 95% CI 0.92-1.46, P = .21). An association was not observed between cigarette smoking and nonrelapse mortality. Cigarette smoking is associated with an increased risk of respiratory failure and relapse within 100 days of allogeneic HSCT. The association with respiratory failure is mediated in part by abnormal lung function before transplantation and likely through other mechanisms as well. Given the adverse effects associated with cigarette smoking before transplantation, future studies should focus on obtaining accurate smoking histories, tracking prospective changes in smoking status, and assessing the benefits of tobacco cessation on outcomes in this population.

Abstract
We examined the efficacy of unrelated cord blood (CB) transplantation in children with thalassemia (n = 35) and sickle cell disease (n = 16), using data reported to 3 registries. Donor-recipient pairs were matched at HLA-A and -B (antigen level) and DRB1 (allele level) in 7 or HLA mismatched at 1 (n = 18), 2 (n = 25), or 3 loci (n = 1). Transplant conditioning was myeloablative (n = 39) or reduced intensity (n = 12). Neutrophil recovery with donor chimerism was documented in 24 patients; 11 patients developed grade II-IV acute graft-versus-host disease (aGVHD) and 10 patients, chronic GVHD (cGVHD). Overall survival (OS) and disease-free survival (DFS) were 62% and 21% for thalassemia and 94% and 50% for sickle cell disease (SCD), respectively. In multivariate analysis, engraftment rate (hazard ratio [HR] 2.2, P = .05) and DFS (HR 0.4, P = .01) were higher with cell dose >5 × 10(7)/kg. The 2-year probability of DFS was 45% in patients who received grafts with cell dose >5 × 10(7)/kg and 13% with lower cell dose. Primary graft failure was the predominant cause of treatment failure occurring in 20 patients with thalassemia and 7 patients with SCD. Primary graft failure was fatal in 5 patients with thalassemia. These results suggest that only CB units containing an expected infused cell dose >5 × 10(7)/kg should be considered for transplantation for hemoglobinopathy.

Abstract
Cord blood transplantation (CB-T) is increasingly used as a treatment alternative for hematologic malignancies. However, how CB-T compares to related (RD-T) and unrelated donor transplantation (URD-T) is not established. We compared survival of 75 double-unit CB-T, 108 RD-T, and 184 URD-T recipients who received transplants over the same period for the treatment of hematologic malignancies. Patients had similar ages and disease risk, and a similar percentage had acute leukemia. The incidence of day 180 transplant-related mortality (TRM) of 21% (95% confidence interval [CI]: 12-31) after CB-T was higher than that of RD-T recipients. However, this was compensated for by a low risk of TRM after day 180, and a relatively low incidence of relapse. Hence, the 2-year progression-free survival (PFS) of 55% (95% CI: 45-68) after CB-T was similar to that after RD-T or URD-T (P = .573). In multivariate analysis, donor source had no influence on PFS, with the only significant factors being recipient age and disease risk. In a subanalysis of 201 patients with acute leukemia, CB-T, RD-T, and URD-T recipients also had similar 2-year disease-free survival (P = .482). These data provide strong support for the further investigation of double-unit CB grafts as an alternative hematopoietic stem cell source.

Abstract
BACKGROUND AND OBJECTIVES The aim of this single center study was to assess the impact of pre-transplant factors on long-term follow-up in young patients affected by high-risk acute lymphoblastic leukemia (ALL) who underwent an unrelated cord blood transplant (CBT). The conditioning regimens, graft-versus-host disease (GVHD) prophylaxis and supportive policies were uniform for all patients. DESIGN AND METHODS We analyzed the results of CBT performed in 30 patients, aged <18 years, affected by high risk ALL. As conditioning regimen, all patients received 12 Gy fractionated total body irradiation, etoposide, cyclophosphamide and horse anti-lymphocyte globulin. GVHD prophylaxis consisted of 6-methylprednisolone and cyclosporine A. RESULTS The cumulative incidence of engraftment was 93% (95% CI:0.85-0.93). The cumulative incidence of grade III-IV acute and chronic GVHD was 7% (95% CI:0.01-0.19) and 33% (95% CI: 0.17-0.64), respectively. The 9-year cumulative incidence of transplant-related mortality and relapse was 34% (95% CI:0.13-0.45) and 31% (95% CI:0.16-0.61), respectively. The 9-year overall survival, leukemia-free survival and event-free survival were 42% (95% CI:0.52-0.93), 47% (95% CI:0.25-0.61) and 46% (95% CI:0.33-0.61), respectively. A number of CFU-GM <1 x 10(4)/Kg of recipient body weight was the only factor that negatively affected all outcome parameters both in univariate and multivariate analyses. INTERPRETATION AND CONCLUSIONS The infused cell dose expressed as in vitro progenitor cell growth represents the most important pre-transplant factor affecting the long-term outcome after an unrelated CBT in young patients with high risk ALL. The number of CFU-GM should thus be considered in the selection process of cord blood units for transplant.

Abstract
The allogenic transplantation of hemopoietic stem cell from bone marrow and peripheral blood is limited due to the necessity to identify HLA matched donor within the family or in bone marrow donor registries. Although, more than 10 million donors are available worldwide, completely HLA matched donors could be found only for 75% of the patients. It is well known that transplantations of hematopoietic stem cell from cord blood are characterized with a lower risk of GvHD and therefore do not require so strict criteria for HLA matching, and less time for search of matched donor is needed. The necessity to establish a National cord blood bank in Bulgaria is emphasized further by the heterogeneity of HLA allele and haplotype distribution in the Bulgarian population. That could be explained by the ethnic diversity of the population. As a result some alleles are more frequent in Bulgarians compared to other populations. The organization, accreditation, and development of a strategy for a National cord blood bank will be discussed.

Abstract
UNLABELLED Umbilical cord blood (UCB) banks have increased their stock worldwide in the past years. There are more than 230,000 available units today. The ideal UCB graft is a unit that is matched in five or six of six HLA. A, B (low-resolution) and DRB1 (high-resolution) alleles and which has over 2.5 x 107 nucleated cells/kg body weight (BW). Four of six matched units are also used specially if the cell dose gives more than 3 x 10(7) nucleated cells/kg BW. Our unrelated donor UCB transplant program was started in 1996 searching international cord blood banks (Netcord, New York) for patients with a definitive or potential indication for stem cell transplantation who lacked a matched family donor. PATIENTS AND METHODS From 1995 to 1996, a search was initiated for 87 patients with malignant (n = 56, 37 acute leukemia) and nonmalignant conditions (16 congenital diseases, 14 aplastic anemia). Patient data along with low-resolution A, B, and DR typing were sent to the New York Blood Center, along with a blood sample for high-resolution DRB1 typing. Parallel searches were done in the Netcord database among UCB units with reported high-resolution DRB1 typing. Forty-eight searches were done between 1995 and 2000 (31 with high resolution) and 39 were done between 2000 and 2005 (33 with high resolution). UCB units were considered adequate if they had more than 2.7 x 10(7) cells/kg BW. RESULTS During the first period, four patients (13%) matched five of six high-resolution unit and 21 (67%) a four of six match. During the second period, 15 patients (46%) found a five of six match and 16 (48%) a four of six match (P = .012). CONCLUSION Nearly half of our patients find an optimal matched UCB unit for transplantation in international banks. The creation of a local UCB bank in our country is supported by these data.

Abstract
Pediatric hematopoietic stem cell transplantation (SCT) has been well established. Recent advances in the transplantation conditioning regimens and in the stem cell sources allow us to increase the candidates for transplantation, but the actual number of pediatric SCTs has been decreased because of the decline in the pediatric population and the progress of various chemotherapies and molecular targeted therapies. Pediatric SCT has become rather sophisticated. Cord blood (CB) stem cell transplantation has the problem of rejection and high relapse rate in the advanced malignant diseases. To overcome the rejection and relapse, it is important to select CB with a large number of the cells and the HLA-mismatched CB. Reduced intensity preparative regimens are increasingly adopted to reduce the early and late transplantation-related complications. In the pediatric setting, reduced intensity transplantation is still under investigation. Late complications for pediatric SCT, growth failure and secondary malignancies should be considered for the increasing number of long-term survivors.

Abstract
The number of unrelated cord blood transplants is increasing, with more than 8000 patients reported worldwide. Criteria of donor choice have been identified. Cell dose measured by number of nucleated cells is the most important factor, thus increases in cell dose can partially overcome the presence of HLA incompatibilities. Overall, increasing the number of HLA incompatibilities is associated with non-engraftment, but it also decreases the risk of relapse in patients with malignant disease, resulting in an absence of effect of HLA incompatibilities on event-free survival (survival without relapse or complications related to the transplant). However, in patients with non-malignant disorders, increasing the number of HLA incompatibilities decreases the overall survival. These results show that criteria of donor choice based on number of infused cells, number of HLA incompatibilities and diagnosis improve outcomes of unrelated cord blood transplants. Currently, owing to the possibility of using a non HLA identical donor, most patients can find a donor, increasing the need for the development of the inventory of cord blood banks. Methods of improving engraftment are currently under investigation.

Abstract
In two institutions in México, twelve patients were given a second allogeneic stem cell transplantation, using the "Mexican" non-myeloablative preparative regimen. Eight had a malignant condition (six acute leukemias, one myelofibrosis and one myelodysplasia), eleven individuals were allografted twice from the same donor and in one case, cells from two different umbilical cords were used. The median time to conduct the second allograft after the first one was 6 months (range 1-41). The five patients who failed to engraft after the first transplant failed also to engraft after the second one; all of them had been heavily transfused. Only three patients were successfully rescued with the second transplant, two with acute leukemia and one with aplastic anemia. Seven patients are alive 10-41 months (median 35) after the second transplant, but only three (25%) remain disease-free. The 52-month overall survival (SV) of the patients is 58%, whereas the median overall SV has not been reached, being above 52 months. Conducting a second allograft may be useful to rescue some individuals relapsing after a first hematopoietic allotransplant.

Abstract
OBJECTIVE Private umbilical cord blood (UCB) banking after delivery has increased over the last decade. For adult/somatic stem cell research UCB is an essential source of stem cells and researchers question if the number of UCB samples for research might be reduced by private banking. METHODS A survey among seven private blood banks in Germany and analysis and comparison of the number of UCB samples donated for research within the STEMMAT project with private blood banking were performed from 03/2003 to 06/2005 at the Frauenklinik (OB/GYN), Technical University Munich, Germany. RESULTS Within 27.5 months 1,551 UCB samples were collected for research purposes; the effective recruitment rate was higher than expectations at an effective 66.2 %. Private UCB banking [n = 24] was distributed among three cord blood banks [n = 16, 6 and 4]. The rate of private blood banking was 0.99 % for all deliveries, thus reducing the effective rate for research purpose by only 1.5 %. CONCLUSION Under the assumption of active and successful recruitment of scientific UCB samples, private blood banking does not significantly reduce this rate and therefore is a negligible rival in the competition for sufficient numbers of UCB samples for research.

Abstract
The Sibling Donor Cord Blood (SDCB) Program was initiated in 1998 as a resource to collect, characterize, and release cord blood units (CBUs) from families affected by malignant and nonmalignant disorders for transplantation. Families in the United States were recruited by telephone after referrals by community and academic physicians. Collection kits were mailed to prospective participants and family members were instructed about CBU procurement from community hospitals and shipping to a central laboratory. Data about the infant's delivery and CBU harvest, CBU processing, prethaw characteristics, sterility, and human leukocyte antigen (HLA) typing were collected. Standard outcome data were collected after CBU release for transplantation. Descriptive analyses of CBU collections, processing, release, and transplantation outcomes were performed. Currently, 1617 CBU collections have been processed from families with thalassemia (6%), sickle cell disease (28%), malignant disorders (49%), and other rare hematological disorders (17%). Thirty-two of 96 donor-recipient pairs with thalassemia major were HLA identical and 14 have received cord blood transplantation, either alone or in combination with bone marrow or peripheral blood progenitor cells (N = 4) from the same donor. Eleven of the 14 survive free of thalassemia after transplantation. These preliminary results confirm the feasibility and utility of remote-site sibling donor cord blood collection and subsequent transplantation for hematological disorders, with a very high rate of usage from a cord blood bank dedicated to performing these unique collections. It was concluded that cord blood transplantation from sibling donors represents a suitable alternative to bone marrow transplantation.

Abstract
In therapy of rapidly fatal diseases, early treatment efficacy often is characterized by an event, "response," which is observed relatively quickly. Since the risk of death decreases at the time of response, it is desirable not only to achieve a response, but to do so as rapidly as possible. We propose a Bayesian method for comparing treatments in this setting based on a competing risks model for response and death without response. Treatment effect is characterized by a two-dimensional parameter consisting of the probability of response within a specified time and the mean time to response. Several target parameter pairs are elicited from the physician so that, for a reference covariate vector, all elicited pairs embody the same improvement in treatment efficacy compared to a fixed standard. A curve is fit to the elicited pairs and used to determine a two-dimensional parameter set in which a new treatment is considered superior to the standard. Posterior probabilities of this set are used to construct rules for the treatment comparison and safety monitoring. The method is illustrated by a randomized trial comparing two cord blood transplantation methods.

Abstract
This EBMT activity survey presents the status of hematopoietic stem cell transplantation (HSCT) in Europe 2003 and focuses on changes in stem cell source over the last decade. There were 21 028 first HSCT, 7091 allogeneic (34%), 13 937 autologous (66%) and 4179 additional re- or multiple transplants reported from 597 centers in 42 European countries in the year 2003. Main indications were leukemias (6613 (31%; 78% allogeneic)); lymphomas (11 571 (55%; 93% autologous)); solid tumors (1792 (9%; 92% autologous)) and nonmalignant disorders (898 (5%; 93% allogeneic)). In 1991, the vast majority of autologous and all allogeneic HSCT were still bone marrow (BM) transplants. Stem cell source changed rapidly to peripheral blood (PB) for autologous HSCT between 1992 and 1996. In 2003, 97% of autologous HSCT were PB derived. The change to PB for allogeneic HSCT followed 3 years later and occurred at a lower rate. In 2003, 65% of all allogeneic HSCT were PB derived. The change in stem cell source was not homogeneous. It was associated with donor type, main diagnosis, disease stage and it differed between European countries. In 2003, bone marrow remains a significant source of stem cells in some European countries for autologous HSCT and for nonmalignant disorders in allogeneic HSCT.

Abstract
Abstract
Allogeneic hematopoietic stem cell transplantation is a life-saving procedure for hematopoietic malignancies, marrow failure syndromes, and hereditary immunodeficiency disorders. However, wide application of this procedure is limited by availability of suitably HLA-matched adult donors. Umbilical cord blood (UCB) has being increasingly used as an alternative hematopoietic stem cell source for these patients. To date, over 6000 UCB transplant procedures in children and adults have been performed worldwide using UCB donors. Broader use of UCB for adult patients is however limited by the available infused cell dose. This has prompted intensive research on ex vivo expansion of UCB stem cells and UCB graft-engineering including accessory cells able to improve UCB engraftment and reconstitution and for tissue regenerative potential. Recently, two large European and North American retrospective studies demonstrated that UCB is an acceptable alternative source of hematopoietic stem cells for adult recipients who lack HLA-matched adult donors. UCB is anticipated to address needs in both transplantation and regenerative medicine fields. It has advantages of easy procurement, no risk to donors, low risk of transmitting infections, immediate availability and immune tolerance allowing successful transplantation despite HLA disparity.

Abstract
OBJECTIVE Optimizing cord blood donor selection based mainly on cell dose and human leukocyte antigen (HLA) disparities may further improve results of unrelated cord blood transplants (UCBT). MATERIALS AND RESULTS We analyzed 550 UCBTs for hematologic malignancies reported to the Eurocord Registry. Main outcomes and prognostic factors were analyzed in univariable and multivariable analyses incorporating center and period effects and using death and relapse as competitive risks for nonfatal endpoints. Nucleated cell (NC) dose before freezing and number of HLA disparities had a significant influence on outcome. Cumulative incidence (CI) of neutrophil and platelet recovery was associated with the number of HLA mismatches, number of NC before freezing, and use of granulocyte colony-stimulating factor. Coexistence of HLA class I and II disparities and high CD34 cell dose in the graft were associated with graft-vs-host disease grades III-IV. CI of disease relapse was higher in matched transplants showing a graft-vs-leukemia effect increased in HLA-mismatched transplants. Overall 3-year survival was 34.4%. Prognostic factors for survival were recipient age, gender, and disease status. CONCLUSION Our results provide indications for a better choice of cord blood units according to cord blood cell content and HLA.

Abstract
From July 1995 to December 2001, 42 patients with leukemia aged 1-42 years underwent cord blood transplant (CBT) from unrelated, < or = 2 antigen HLA mismatched donors. In all, 26 patients were in < or = 2nd complete remission and 16 in more advanced phase. Conditioning regimens, graft-versus-host disease (GVHD) prophylaxis and supportive policy were uniform for all patients. The cumulative incidence of engraftment was 90% (95% CI: 0.78-0.91). The cumulative incidence of III-IV grade acute- and chronic-GVHD was 9% (95% CI: 0.04-0.24) and 35% (95% CI: 0.21-0.60), respectively. The 4-year cumulative incidence of transplant-related mortality (TRM) and relapse was 28% (95% CI: 0.17-0.47) and 25% (95% CI: 0.14-0.45), respectively. The 4-year overall survival (OS), leukemia-free survival (LFS) and event-free survival (EFS) were 45% (95% CI: 0.27-0.63), 47% (95% CI: 0.30-0.64) and 46% (95% CI: 0.30-0.62), respectively. In multivariate analysis, the most important factor affecting outcomes was the CFU-GM dose, associated with CMV serology (P=0.003 and 0.04, respectively) in influencing OS and with patient sex (P=0.008 and 0.03, respectively) in influencing LFS. Finally, CFU-GM dose was the only factor that affected EFS significantly (P=0.02). In conclusion, the infused cell dose expressed as in vitro progenitor cell growth is highly predictive of outcomes after an unrelated CBT and should be considered the main parameter in selecting cord blood units for transplant.

Abstract
This report summarizes current transplant activity in Europe. It is based on the activity survey of the European Group for Blood and Marrow Transplantation (EBMT). Introduced in 1990, the survey captures the annual numbers of hematopoietic stem cell transplantation (HSCT) by indication, donor type and stem cell source from each individual European transplant team. Supplemented by demographical data and economical factors, team density and transplant rates can be calculated, and the impact of economics on HSCT rates can be assessed. As documented in the present analysis, in the year 2002, a total 20 207 HSCT were performed on new patients in Europe by 586 teams in 39 countries: 6915 being allogeneic and 13 292 autologous HSCT. The main indications for allogeneic HSCT were leukemias, lymphoproliferative disorders and non-malignant diseases; main indications for autologous HSCT were lymphoproliferative disorders, solid tumors and leukemias. The main source of stem cells were peripheral blood (96%) for autologous, peripheral blood (62%) and bone marrow (38%) for allogeneic HSCT. On the basis of its completeness, the EBMT activity survey presents a rapid description of the status quo, assessment of trends and determination of factors influencing transplant rates. As such, it provides up-to-date information for patients, treating physicians and health-care officials.

Abstract
BACKGROUND Prolonged periods of marrow hypoplasia have been a problem in cord blood transplantation. DMSO is thought to produce osmotic shock to the progenitors when the thawed cells are infused into the patients. To solve this problem, a 2x dilution method originally developed in the New York Blood Center showed earlier myeloid engraftment,1 although follow-up clinical studies have not performed. STUDY DESIGN AND METHODS To clarify the influence of the removal of DMSO by this method on the speed of engraftment in unrelated cord blood transplantation, 46 adult patients with cord blood units processed by the Tokyo Cord Blood Bank from September 1998 to March 31, 2002 were studied. Twenty-four patients received 2.6 +/- 0.71 x 10(7) nucleated cells per kg without washing (nonwashed group), while 22 patients were received 2.7 +/- 0.52 x 10(7) nucleated cells per kg after 2x dilution washing (washed group). RESULTS The cumulative incidence of engraftment was not significantly different between the two groups. Median neutrophil recovery (>/=5 x 10(9)/L) in the nonwashed and washed groups was 26 and 25 days, respectively, and the median platelet recovery (>/=20 x 10(9)/L) in patients with myeloid engraftment was 44 and 40 days, respectively (NS). On the other hand, the doses of CFCs and CD34+ cells showed the influence on myeloid and platelet recovery. CONCLUSION A 2x dilution after thawing cord blood did not result in the improvement of myeloid engraftment speed.

Abstract
Hematopoietic stem cell transplantation (HSCT) is the only curative option for patients with hemoglobinopathies. However, fewer than 30% of individuals will have an HLA-identical sibling. Improvement in outcomes after HSCT using unrelated donors (URD), and the development of novel nontoxic preparative regimens may make URD HSCT an option for hemoglobinopathy patients who do not have an HLA-identical sibling donor. The National Marrow Donor Program (NMDP) maintains a Registry of 4 million volunteer donors, and facilitates URD HSCT for patients with life-threatening blood diseases. In light of the increased representation of minorities in the NMDP registry, donor searches were run in April 2001 for a cohort of 272 thalassemia patients and 77 sickle cell disease (SCD) patients for whom searches had been submitted between 1989 and 2001 in order to determine the current likelihood of finding a potential donor of hematopoietic stem cells for hemoglobinopathy patients. About 59.7% SCD patients 80.2% thalassemia patients will find at least one potential 6/6 HLA matched donor or umbilical cord blood (UCB) unit. All patients will find at least one donor or UCB that is a potential 5/6 HLA match. In conclusion the majority of hemoglobinopathy patients will find at least one potential HLA matched unrelated bone marrow donor or UCB.

Abstract
As a source for hematopoietic stem cell transplantation (HSCT), cord blood transplantation from unrelated donors (UCBT) is now considered as an acceptable alternative to patients who need unrelated HSCT. To confirm the findings that mismatched UCBT is feasible, we discussed here the results for 477 patients with hematologic malignancies and non-malignancies who were subjected to UCBT coordinated by the Japanese Cord Blood Bank Network (JCBBN). From February 1997 to October 2001, 411 patients with malignancies and 66 with non-malignancies had UCBT through the cord blood bank in the JCBBN; 311 patients had HLA 0-1 mismatched UCBT; 165, had a 2-4 HLA mismatch. The Kaplan-Meier estimates for 3-year disease-free survival rate (DFS) were 35.2 +/- 2.8% in malignant diseases, and 33.6 +/- 7.2% in patients with non-malignant diseases. The HLA disparity had no effect on DFS, incidence of acute graft-versus-host disease, or engraftment. As reported previously, we also noted the importance of graft cell dose in determining survival in UCBT. Major advantages of UCBT include its rapid availability compared with unrelated donor bone marrow, and tolerance of an HLA mismatch at 2 loci, which will enable extension of the donor pool. This review outlines the latest UCBT progress, with emphasis on practical considerations in HLA-mismatched umbilical cord blood selection.

Abstract
Since 1990, the EBMT has annually collected numbers of HSCT by disease indication, donor type and stem cell source. The 2001 survey concentrates on the use of reduced intensity conditioning (RIC) transplants and its dissemination in Europe. In 2001, there were 19576 HSCT for new patients, 6413 with allogeneic HSCT (33%), 13163 with autologous HSCT (67%) and 3256 additional re- or multiple transplants, 868 (667/201) allogeneic and 2658 (537/2121) autologous, collected from 596 centers in 35 European countries. The main indications in 2001 were leukemias (32%; 73% of them allogeneic); lymphomas (53%; 92% of them autologous); solid tumors (11%; 93% of them autologous) and non-malignant disorders (4%; 90% of them allogeneic). Compared to 2000, there was a drop in allogeneic HSCT of over 20% for chronic myeloid leukemia and an increase of 2% in autologous HSCT. A total of 1759 or 27% of allogeneic transplants were reported as RIC HSCT. These have risen in number in 3 years from <1% in 1998. There are wide variations from 0 to 71% RIC HSCT in European countries with no obvious explanation. These data document the current status of blood and marrow transplantation in Europe and indicate a marked change towards RIC HSCT in allogeneic transplantation.

Abstract
Umbilical cord blood (UCB) has been used successfully as an alternative source of haemopoietic stem cells (HSC) in allogeneic stem-cell transplantation for the treatment of acquired and genetic diseases. Advantages of using UCB include: (i) no risk to the donor, (ii) no donor attrition, (iii) minimal risk of viral transmission and (iv) immediate availability. Early results have highlighted differences in engraftment rates and toxicity between UCB and other sources of HSC. These differences relate to the low cell dose in UCB and also to the intrinsic properties of UCB. In this article, the clinical outcome of UCB transplantation (UCBT) will be reviewed with a discussion of the biological characteristics of UCB that may account for some of the clinical outcomes. To overcome the limitations of low cell dose, novel approaches such as ex vivo expansion of HSC are being actively explored, and this will be summarized in the present study. Finally, the success of UCBT has led to the establishment of dedicated UCB banks worldwide and the regulatory issues surrounding this will be briefly discussed.

Abstract
Cord blood offers many advantages including a high concentration of hematopoietic stem cells, a large number of potential donors, and ease of harvest. Furthermore, since there is no risk for either the mother or baby, few people refuse to donate. There is thought to be a low risk for virus contamination and also probably a low incidence and severity of GVHD. Cord blood can be obtained quickly without the assistance of a coordinator and one or 2 locus-mismatched HLA is usually acceptable. In Japan, there are 10 cord blood banks supported by the government. Between 1996 and June 2002, 9,500 units were registered with the Japan cord blood bank network (JCBBN). 630 units were delivered and most of these were transplanted. The status of registered cord blood units worldwide is shown. 59,081 units have been registered by NETCORD. The Japan cord blood bank network accounts for 13% of these units. I will discuss the Tokyo cord blood tank (TCBB). The bank at Tokyo, to which we belong, is one of the largest banks in Japan. We helped to establish Asia CORD in 2000 and have held annual conferences and meetings in Tokyo to exchange information. So far, China, Korea, Taiwan, Thailand, Viet Nam and Japan have participated. We accepted three trainees from the Ho Chi Minh City Blood Transfusion and Hematology Center for training in cord blood transplantation in May 2001. In January 2002, a patient with ALL received cord blood and was successfully engrafted at Ho Chi Minh City Blood Transfusion and Hematology Center. We present here the clinical outcome of these patients through Tokyo cord blood bank and Japan cord blood bank network. First, the number of CB units stored and registered at JCBBN and TCBB has increased rapidly over the past two years. Second, the survival rate of acute leukemia patients in release was significantly lower than that in patients in CR. Third, the engraftment rate in patients with metabolic disease (50%) was lower than that in patients with leukemia. Fourth, there was no significant difference in the incidence of acute GVHD greater than grade II between patients with a 1-locus and 2-locus mismatch. Finally, the incidence of acute GVHD was relatively low, and there were no deaths related to acute GVHD.
