About 600 autologous (where the patient receives their own stem cells) and about 300 allogeneic (where the patient receives stem cells from another person) stem cell transplantations are performed in Sweden every year. About 70% of those in need of a stem cell transplant do not have a suitable donor in their family and need to find a donor who is not related. Of the allogeneic stem cell transplants performed in 2022, 207 were with a donor who was not related.
