In the last 10 years, numbers of donors in the case of Polish potential unrelated hematopoietic stem cells (HSC) have increased dynamically, reaching 1,900,000 in 2020 (including donors presented in World Marrow Donor Association as PL6). On the world scale, the share of Polish donors in the global registry increased from 1% in 2010 to about 5% in 2020. The level and range of typing of potential donors has also been improving steadily toward the international "gold standard." At the end of 2020, 92% of Polish resources were at least HLA-A, B, C, DR, DQ high- or intermediate-resolution typed, mostly by way of genomic typing techniques, mostly by way of genomic typing techniques. The Central Bone Marrow Donor Registry (CBMDR) also stands out in terms of the young ages of potential donors. As of 2020, 27.2% of those registered were younger than 30 years of age, and 36.3% were aged between 30 and 40 years. Sixty percent of registered donors were female. The data in question were presented at the World Marrow Donor Association SearchMatch Service, ensuring their visibility and accessibility to Polish and international search units and registries. In 2020, donors in Poland were the subject of almost 18,000 search requests from 40 countries, with 271 extended typing requests and more than 7600 confirmatory typing requests. The total number of donations from Polish donors also increased. In 2020, HSC of bone marrow, peripheral blood, or lymphocytes were collected from 1391 donors, as opposed to 94 donors in 2010. The growing number of donors available in the CBMDR means a better chance of a donor being found among Polish resources, without any need to resort to international registers. Although in 2010, just 24% of Polish recipients received HSC from Polish donors, by 2019 the figure was as high as 67%, and reached 63% in 2020. The CBMDR is an example of proper strategy on registry development being implemented in Poland. |
