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.

LACE-conditioned autologous stem cell transplantation for relapsed or refractory Hodgkin's lymphoma: treatment outcome and risk factor analysis in 67 patients from a single centre.
High-dose chemotherapy followed by autologous stem cell transplantation (ASCT) is a recognized treatment option for patients with relapsed Hodgkin's lymphoma. We have analysed 67 patients who underwent ASCT after LACE (lomustine (CCNU), cytarabine (Ara-C), cyclophosphamide, etoposide) conditioning for relapsed (n=61) or primary refractory (n=6) Hodgkin's lymphoma. The 100-day treatment-related mortality was 3%. ⋯ Probabilities for OS and PFS at 5 years for patients with chemosensitive relapse (n=40) were 81 and 78% versus 50 and 35%, respectively, for patients (n=27) with chemoresistant relapse (P=0.012 for OS, P=0.002 for PFS). In multivariate analysis mixed cellularity classical or lymphocyte-depleted classical histology subtype and haemoglobin level of 10 g/dl or less at the time of ASCT were identified as risk factors for worse OS, whereas stage III or IV disease at diagnosis and disease status at ASCT other than complete or partial remission predicted inferior PFS. LACE followed by ASCT is an effective treatment for the majority of patients with chemosensitive relapsed Hodgkin's lymphoma and a proportion of chemorefractory patients also benefit.
