Abstract

The purpose of this study was to evaluate the strategy of haploidentical (HID) stem cell combined with a small doses of umbilical cord blood (UCB) from a third-party donor transplantation (haplo-cord transplant) for treatment of myelodysplastic syndromes (MDS), by comparing with identical-sibling donor (ISD) transplantation. Eighty-five patients were included between January 2012 and December 2015, with a median 40 years old. Forty-eight patients received haplo-cord transplant and 37 patients received ISD transplant. Haplograft engraftment succeeded in all haplo-cord patients. For haplo-cord and ISD transplantation, adjusted cumulative incidences of grades 2-4 acute GvHD at 100 days were 27 and 11% (P=0.059); adjusted cumulative incidences of chronic GvHD at 2 years were 22 and 34% (P=0.215). The 2-year adjusted probabilities of overall survival were 64 and 70% (P=0.518), and of relapse-free survival were 56 and 66% (P=0.306). The 2-year adjusted cumulative incidences of relapse were 12 and 14% (P=0.743), and of non-relapse mortality were 33 and 23% (P=0.291). In conclusion, haplo-cord-HSCT achieves outcomes similar to those of ISD-HSCT for MDS and the haplo-cord-HSCT may potentially improve the outcome of HID- and UCB-HSCT alo...Continue Reading

Allogenic & Autologous Therapies

Allogenic therapies are generated in large batches from unrelated donor tissues such as bone marrow. In contrast, autologous therapies are manufactures as a single lot from the patient being treated. Here is the latest research on allogenic and autologous therapies.

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.
