Bloodless (transfusion-free) hematopoietic stem cell transplants: the Mexican experience

Abstract

We have analyzed the transfusion requirements of a group of 132 peripheral blood stem cell transplants from a single institution (73 allografts and 59 autografts) over a 10-year period. The allografts were conducted using the 'Mexican' nonmyeloablative conditioning regimen, while the autografts were given single-day high-dose melphalan. For the allografts, the median number of transfused packed red blood (PRBC) cell units was 1 (range 0-22), while the median number of platelet transfusion (PLT) sessions was 1 (range 0-9); 45% of allografted individuals did not require PRBC transfusions and 35% did not require PLT. For autografts, the median number of PRBC units was 2 (range 0-21), while the median number of PLT was 2 (range 0-21); 33% of autografted individuals did not require PRBC and 25% did not require PLT. We conclude that, by using certain preparative regimens, both allo and auto hematopoietic stem cell grafts can be conducted without the transfusion of blood products.
