SCT is a curative approach using chemo-, radio- and immunotherapy for malignant and non-malignant hematological disorders. The European Group for Blood and Marrow Transplantation (EBMT) has been collecting yearly data on a survey basis since 1990. The variables within the survey are limited to detailed indications, number of patients, transplant type, stem cell source, type of conditioning regimen and donor type. The transplant rates in certain indications, patterns of stem cell source selection and donor availability and alternative donor use were analyzed in detail. The Turkish transplant registry data within EBMT-European Activity Survey (EBMT-EAS) were delivered by the EBMT Activity Survey Office. We compared the national data with the international EBMT-EAS data pool.
