Multicenter StudyHaematopoietic stem cell transplantation trends in children over the last three decades: a survey by the paediatric diseases working party of the European Group for Blood and Marrow Transplantation.
This paper describes the trends in haematopoietic stem cell transplantation (HSCT) activity for children in Europe over the last three decades. We analysed 31,713 consecutive paediatric HSCTs reported by the European Group for Blood and Marrow Transplantation (EBMT) centres between 1970 and 2002. Data were taken from the EBMT registry and were compared according to period and centre category (paediatric or combined). ⋯ Multivariate analysis showed that both auto-HSCT performed before 1996 and paediatric solid tumours (P<0.0001) had higher TRM. Indications for paediatric HSCT have changed considerably during the last seven years. These changes provide tools for decision making in health-care planning and counselling.

Multicenter StudyResults of the EBMT activity survey 2005 on haematopoietic stem cell transplantation: focus on increasing use of unrelated donors.
This EBMT activity report documents the haematopoietic stem cell transplantation (HSCT) activity in Europe in 2005. It provides numbers of HSCT by indication, donor type and stem cell source, lists the new practice of planned double transplants with allogeneic after autologous HSCT and concentrates on the increasing role of unrelated transplants over the last years. In 2005, there were 24,168 first HSCT, 8890 allogeneic (37%), 15,278 autologous (63%) and 3773 additional re- or multiple transplants reported from 597 centres in 43 participating countries. ⋯ The most noticeable increase was in unrelated HSCT, which comprise 41% of all allogeneic HSCT. Unrelated HSCT were preferentially performed for leukaemias and in countries with high income according to World Bank criteria. These data illustrate the current experience in Europe and form the basis for patient counselling and decisions making at health care institutions.

Multicenter Study Comparative StudyComparison of long-term outcomes after allogeneic hematopoietic stem cell transplantation from matched sibling and unrelated donors.
Long-term survivors of hematopoietic stem cell transplants remain at risk of potentially fatal complications that detract from life quality. Long-term morbidity and mortality were compared between matched recipient cohorts surviving 2 or more years and defined by donor type, HLA matched sibling donor (MSD) or volunteer unrelated donor (URD). Patients were previously entered into the prospective multicenter International Unrelated Search and Transplant Study. ⋯ Cumulative incidence of extensive c-GvHD (P=0.002), cataracts (P=0.02) and bone necrosis (P=0.02) was higher after URD transplants. No long-term difference in endocrine dysfunction, secondary malignancy and major dental pathology was detected. This landmark study will assist physicians counseling patients pre-transplant and with their long-term care post transplant.

Multicenter Study Historical ArticleEBMT activity survey 2004 and changes in disease indication over the past 15 years.
This fifteenth annual European Group for Blood and Marrow Transplantation activity report lists the transplant activity in Europe in 2004 and documents the changes in indication over the past 15 years. In 2004, there were 22 216 first hematopoetic stem cells (HSCT), 7407 allogeneic (33%), 14 809 autologous (67%) and 4378 additional re- or multiple transplants reported from 592 centres in 38 European and five affiliated countries. Main indications were leukemias (7045 (32%; 78% allogeneic)); lymphomas (12 310 (55%; 94% autologous)); solid tumors (1759 (8%; 93% autologous)) and nonmalignant disorders (1015 (5%; 92% allogeneic)). ⋯ Leukemias for allogeneic and lymphoproliferative disorders for autologous HSCT continue to increase. The decline in HSCT for chronic myeloid leukemia appears to level off for the first time since 1999. These data are informative for patient counselling and decision making for health care professionals.

Multicenter StudyLong-term outcome of allogeneic PBSC transplantation in pediatric patients with hematological malignancies: a report of the Spanish Working Party for Blood and Marrow Transplantation in Children (GETMON) and the Spanish Group for Allogeneic Peripheral Blood Transplantation (GETH).
We analyzed the clinical outcome in 90 children undergoing allogeneic PBSC transplantation from HLA-identical relative for leukemia. GvHD prophylaxis was CsA+ methotrexate in 50 and CsA+/-steroids in 40. Median CD34+ cells infused were 6 x 10(6)/kg (range, 1.4-32). ⋯ Patients with cGvHD had better DFS (65+/-5%) because of lower RI (15.7+/-6%) and similar TRM (27.4+/-4%). These data suggest acceptable long-term outcomes after allogeneic PBSC transplantation in children despite the high incidence of cGvHD. These patients had a lower risk of relapse and a better DFS.
