RESUMO

Promoting access to and excellence in hematopoietic cell transplantation (HCT) by collecting and disseminating data on global HCT activities is one of the principal activities of the Worldwide Network for Blood and Marrow Transplantation, a non-governmental organization in working relations with the World Health Organization. HCT activities are recorded annually by member societies, national registries and individual centers including indication, donor type (allogeneic/autologous), donor match and stem cell source (bone marrow/peripheral blood stem cells/cord blood). In 2018, 1,768 HCT teams in 89 countries (6 World Health Organization regions) reported 93,105 (48,680 autologous and 44,425 allogeneic) HCT. Major indications were plasma cell disorders and lymphoma for autologous, and acute leukemias and MDS/MPN for allogeneic HCT. HCT numbers increased from 48,709 in 2007. Notable increases were seen for autoimmune diseases in autologous and hemoglobinopathies in allogeneic HCT. The number of allogeneic HCT more than doubled with significant changes in donor match. While HCT from HLA-identical siblings has seen only limited growth, HCT from non-identical related donors showed significant increase worldwide. Strongest correlation between economic growth indicator of gross national income/capita and HCT activity/10 million population was observed for autologous HCT (correlation coefficient [r]=0.79). HCT from unrelated donors showed strong correlation (r=0.68), but only moderate correlation was detected from related donors (r=0.48 for HLA-identical sibling; r=0.45 for other). The use of HCT doubled in about a decade worldwide at different speed and with significant changes regarding donor match as a sign of improved access to HCT worldwide. Although narrowing, significant gaps remain between developing and non-developing countries.

RESUMO

The Worldwide Network of Blood and Marrow Transplantation (WBMT) pursues the mission of promoting hematopoietic cell transplantation (HCT) for instance by evaluating activities through member societies, national registries and individual centers. In 2016, 82,718 first HCT were reported by 1,662 HCT teams in 86 of the 195 World Health Organization member states representing a global increase of 6.2% in autologous HCT and 7.0% in allogeneic HCT and bringing the total to 1,298,897 procedures. Assuming a frequency of 84,000/year, 1.5 million HCT were performed by 2019 since 1957. Slightly more autologous (53.5%) than allogeneic and more related (53.6%) than unrelated HCT were reported. A remarkable increase was noted in haploidentical related HCT for leukemias and lymphoproliferative diseases, but even more in non-malignant diseases. Transplant rates (TR; HCT/10 million population) varied according to region reaching 560.8 in North America, 438.5 in Europe, 76.7 in Latin America, 53.6 in South East Asia/Western Pacific (SEA/WPR) and 27.8 in African/East Mediterranean (AFR/EMR). Interestingly, haploidentical TR amounted to 32% in SEA/WPR and 26% in Latin America, but only 14% in Europe and EMR and 4.9% in North America of all allogeneic HCT. HCT team density (teams/10 million population) was highest in Europe (7.7) followed by North America (6.0), SEA/WPR (1.9), Latin America (1.6) and AFR/EMR (0.4). HCT are increasing steadily worldwide with narrowing gaps between regions and greater increase in allogeneic compared to autologous activity. While related HCT is rising, largely due to increase in haploidentical HCT, unrelated HCT is plateauing and cord blood HCT is in decline.

RESUMO

Hematopoietic cell transplantation (HCT) is a complex and resource-intensive procedure that has become a critical treatment for certain hematologic conditions. However, in Latin America, access to HCT is limited compared to high-income countries, in part due to a lack of standardized training programs for HCT professionals. To address this gap, the Latin-American Bone Marrow Transplantation Group conducted a cross-sectional study to assess the current state of training programs in HCT and cellular therapy across the region. This study aimed to describe and analyze the availability, characteristics, and challenges of HCT training programs in Latin America, with a focus on identifying barriers and proposing solutions for improvement. A cross-sectional survey was sent to 127 recognized HCT centers across 14 Latin-American countries in December 2022. The survey collected data on institutional characteristics, training program structure, costs, and barriers to program development. Descriptive statistics were used to summarize the data, and comparative analyses were performed using Chi-square and Mann-Whitney tests. Of the 127 centers surveyed, 50 (39%) responded, with the majority located in Brazil (34%) and Mexico (30%). Among the respondents, 64% (n = 32) offered formal training programs lasting 6 months or longer. The most significant barriers reported were lack of funding (n = 21), limited number of transplant procedures (n = 15), and a shortage of qualified professors (n = 11). Proposed solutions included increasing student mobility opportunities (n = 28), enhancing program quality (n = 27), and improving access to funding (n = 15). Only 6% of programs offered exposure to CAR-T therapy, and fewer than half of the centers provided international rotations. This study highlights significant disparities in HCT training programs across Latin America, with most countries lacking access to formalized training. While Brazil and Mexico serve as regional hubs, other nations have limited or no training opportunities. Addressing these gaps through increased funding, international collaborations, and standardized curricula is essential to improving HCT training and ultimately patient care in the region.

RESUMO

The eighth workshop of the Worldwide Network for Blood and Marrow Transplantation (WBMT) was held in Islamabad, Pakistan, from September 22 to 23, 2022, aiming to foster hematopoietic stem cell transplant (HSCT) activity in the World Health Organization (WHO) Eastern Mediterranean Region (EMRO). Participating countries, including Pakistan, Oman, Iran, and Saudi Arabia, reported increased HSCT in the last few years, whereas others from the EMRO and beyond, including Qatar, United Arab Emirates, Nepal, and Bangladesh, started HSCT recently and have developed HSCT programs with excellent results. During educational sessions and open dialog, participating teams and international experts from the WBMT shared their experience and discussed minimum essential requirements for establishing and expanding HSCT in emerging countries, indications for HSCT training and dissemination of knowledge, stem cell donor selection and safety, quality assurance in transplant centers, and the value and importance of transplant outcome databases. International support, collaboration, and local engagement, including government participation and WHO assistance, are valuable in increasing HSCT access worldwide.

RESUMO

Hematopoietic cell transplantation (HCT) was developed more than 65 years ago to treat malignant blood disorders and irreversible bone marrow failures, with the aim of replacing a diseased hematopoietic system with a healthy one (allogeneic HCT). Decades later, the procedure was adapted to apply maximal chemotherapy or radiotherapy, which would result in bone marrow failure, but could be remedied by an infusion of a patient's own cryopreserved bone marrow (autologous HCT). Both treatments are high-risk and complex, especially during the initial phases. However, concerted efforts, vision, and collaboration between physicians and centers worldwide have resulted in HCT becoming a standard of care for many hematological disorders with progressive improvements in outcomes. Registries and the collaboration of societies worldwide have enabled the delivery of this curative therapy to many patients with fatal hematological diseases. More than 1.5 million HCT were performed between 1957 and 2019, and activity is continuously increasing worldwide.

RESUMO

Acute myeloid leukemia (AML) has an aggressive course and a historically dismal prognosis. For many patients, hematopoietic stem cell transplantation (HSCT) represents the best option for cure, but access, utilization, and health inequities on a global scale remain poorly elucidated. We wanted to describe patterns of global HSCT use in AML for a better understanding of global access, practices, and unmet needs internationally. Estimates of AML incident cases in 2016 were obtained from the Global Burden of Disease 2019 study. HSCT activities were collected from 2009 to 2016 by the Worldwide Network for Blood and Marrow Transplantation through its member organizations. The primary endpoint was global and regional use (number of HSCT) and utilization of HSCT (number of HSCT/number of incident cases) for AML. Secondary outcomes included trends from 2009 to 2016 in donor type, stem cell source, and remission status at time of HSCT. Global AML incidence has steadily increased, from 102,000 (95% uncertainty interval: 90,200-108,000) in 2009 to 118,000 (104,000-126,000) in 2016 (16.2%). Over the same period, a 54.9% increase from 9659 to 14,965 HSCT/yr was observed globally, driven by an increase in allogeneic (64.9%) with a reduction in autologous (-34.9%) HSCT. Although the highest numbers of HSCT continue to be performed in high-resource regions, the largest increases were seen in resource-constrained regions (94.6% in Africa/East Mediterranean Region [AFR/EMR]; 34.7% in America-Nord Region [AMR-N]). HSCT utilization was skewed toward high-resource regions (in 2016: AMR-N 18.4%, Europe [EUR] 17.9%, South-East Asia/Western Pacific Region [SEAR/WPR] 11.7%, America-South Region [AMR-S] 4.5%, and AFR/EMR 2.8%). For patients <70 years of age, this difference in utilization was widened; AMR-N had the highest allogeneic utilization rate, increasing from 2009 to 2016 (30.6% to 39.9%) with continued low utilization observed in AFR/EMR (1.7% to 2.9%) and AMR-S (3.5% to 5.4%). Across all regions, total HSCT for AML in first complete remission (CR1) increased (from 44.1% to 59.0%). Patterns of donor stem cell source from related versus unrelated donors varied widely by geographic region. SEAR/WPR had a 130.2% increase in related donors from 2009 to 2016, and >95% HSCT donors in AFR/EMR were related; in comparison, AMR-N and EUR have a predilection for unrelated HSCT. Globally, the allogeneic HSCT stem cell source was predominantly peripheral blood (69.7% of total HSCT in 2009 increased to 78.6% in 2016). Autologous HSCT decreased in all regions from 2009 to 2016 except in SEAR/WPR (18.9%). HSCT remains a central curative treatment modality in AML. Allogeneic HSCT for AML is rising globally, but there are marked variations in regional utilization and practices, including types of graft source. Resource-constrained regions have the largest growth in HSCT use, but utilization rates remain low, with a predilection for familial-related donor sources and are typically offered in CR1. Further studies are necessary to elucidate the reasons, including economic factors, to understand and address these health inequalities and improve discrepancies in use of HSCT as a potentially curative treatment globally.

RESUMO

A total of 5642 hematopoietic cell transplants (HCT) in 5445 patients (2196-40% allogeneic and 3249-60% autologous) were reported by 127 teams in 14 Latin American countries that answered the 2018 LABMT/WBMT Global Transplant Activity survey. The transplant rate (defined as the number of first transplants per 10 million inhabitants per year) was 85 (51 autologous and 34 allogeneic) in 2018. The main indications for allogeneic HCT were acute leukemias (60%), while plasma cell disorders and lymphomas were the most common conditions warranting autologous HCT (50 and 36%, respectively). In the allogeneic HCT, HLA-identical siblings were the main type of donor (44%) followed by related mismatched/haploidentical donors (32%). Peripheral blood stem cells were used in 98% of the autologous and in 64% of the allogeneic transplants. From 2012 to 2018, there was a 64% increase of reported HCT (54% in autologous and 80% in allogeneic). In the allogeneic setting, the most pronounced increase in donor type was observed in haploidentical relatives (from 94 procedures in 2012 up to 710 in 2018), surpassing unrelated donors as of 2017. Significant trends detected in Latin America include rising numbers of the procedures reported, a faster increase in allogeneic HCT compared with autologous HCT and a significant increase in family mismatched/haploidentical donors. The LABMT/WBMT activity survey provides useful data to understand the HCT activity and trends in Latin America.

RESUMO

Hematopoietic cells transplants are technically complex and expensive imposing a huge burden on health care systems, especially those in developing countries and regions. In 2017 > 4500 transplants were done in 13 Latin American countries with established transplant programmes. We interrogated data on transplant rate, cost, funding source, hospital type, Gini coefficient and the United Nations Development Programme Inequality-Adjusted Human Development Index to determine co-variates associated with transplant development. Transplant rates varied almost 30-fold between the 13 countries from 345 in Uruguay to 12 in Venezuela with a regional transplant rate 7-8-fold lower compared with the US and EU. We found significant correlations between higher transplant cost, public funding, transplants in private hospitals with transplant rate. Low cost per transplant regardless of payor and transplants done in public hospitals were associated with low transplant rates. In contrast, high cost per transplant funded by the government and transplants done in private hospitals were associated with high transplant rates. Surprisingly, we found transplant rates were higher when transplants cost more, when they were done in private for-profit hospitals and payed for with public funds. These data give insights how to increase transplant rates in Latin America and other developing regions.
