abstract: Allogeneic stem cell transplantation (alloSCT) is increasingly used in the treatment of hematological disorders. In order to demonstrate the national development of alloSCT as well as the effect of the foundation of local transplant centers, data of all alloSCT performed on patients living in Mecklenburg-Vorpommern (MV) during 1991 and 2000 were evaluated regarding date and location of the alloSCT, diagnosis and age of the patient as well as donor type. AlloSCT in patients from MV increased 6 fold from 1991 n=5 to 2000 n=30. Because of the lack of local transplant centers during the period between 1991 and 1997, alloSCT of patients from MV were exclusively performed in other locations, whereas in 2000 only 2 of 30 alloSCT were performed in transplants centers outside MV. With the establishment of local centers, the gap between the numbers of alloSCT between MV and Germany was closed (1991 Germany 4,17/Million inhabitants, MV 2,67/Million inhabitants, 2000 Germany 17,4/Million inhabitants, MV 16,7/Million inhabitants). The increase in the number of alloSCT was mainly due to an increased use of unrelated stem cell donors which increased from n=0 in 1991 to 12 out of 30 in 2000. Another important factor was the increase in the age limit with a mean age of 32 years in 1991 and 43 years in 2000 (upper range 60 years).
  
  
  CONCLUSIONS
  The data reflect the dramatic increase in alloSCT during the last decade caused by factors listed above. In addition, the development of the numbers of transplants of patients in MV supports the need for local transplant centers, since with the opening of local transplant centers the difference of the frequency of alloSCT between Germany and MV was completely eradicated.
