Hematopoietic Stem-Cell Transplant Registry in Poland: 2020 Summaries

In the pandemic year 2020, 634 allogeneic hematopoietic stem-cell (HSC) transplants were performed in Poland, including fully matched and haploidentical family donors (n = 248) as well as unrelated donors transplantation (n = 386). In 48 recipients (7.6%) for allogeneic transplantation, hematopoietic bone marrow cells were transplanted, and in 586 recipients (92.4%), peripheral blood hematopoietic cells. The effect of the pandemic was noticeable but not disastrous-the number of HSC transplants from unrelated donors was lower by 9% compared to 2019 and the use of haploidentical donors slightly increased compared to 2019. Out of all 386 unrelated HSC transplants, the material for 143 transplants (37%) came from international donors, whereas for 243 transplants (63%) material collected from domestic donors was used. Along with the increase in the number of potential bone marrow donors in the national resources, the share of transplants from Polish donors in the total number of transplants increased noticeably from 2006 to 2020. The total number of allogeneic transplants performed in 18 Polish transplant centers between 2006 and 2020 is 7426. Total transplant rates (cumulative number of all allogeneic HSC transplants performed from 2006 to 2020 per 1 million inhabitants) differs between regions and for regions with nonzero number of transplants varies from 520 in Mazowieckie Voivodship to 14 in Lodzkie Voivodship.
