Abstract:
In order to research the related factors of umbilical cord blood transplantation, 54 cases of unrelated umbilical cord blood transplantation were analyzed retrospectively, which were performed from June 1998 to July 2003. All cord blood units were obtained from full term normal vaginal deliveries in Guangzhou Maternal-Neonatal Hospital. The fractionation, cryopreservation and thawing of cord blood have been done according to the regulation of New York umbilical cord blood bank and pertinent literature. The selection of cord blood is based on HLA typing and the number of nucleated cells. The results showed that from June 1998 to July 2003, 3 475 units of cord blood were collected in Guangzhou Umbilical Cord Blood Bank and 99 units were provided for therapy of 85 patients in 21 transplantation centers, including 11 sibling and 74 unrelated cord blood transplantations. 54 cases of unrelated cord blood transplantation were reported, including 43 malignant diseases and 11 non-malignant diseases. The median age of recipients was 9.5 (range 1.2 - 33) years, the median weight was 27 (range 10 - 60) kg, the median number of TNC was 6.82 x 10(7)/kg, 43 cord blood were implanted (ANC > 500/microl) at day 60 after transplantation (79.6%, median 17). The time of nuclear cell reconstitution after cord blood transplantation was statistically related with nucleated cells and the type of disease, not related with HLA matching. Acute GVHD was present in 8 patients (21.6%) and chronic GVHD occurred in 2 patients (5.4%), 6 patients suffered from graft failure (11.1%). The total survival rate was 42.6%. It is suggested that unrelated umbilical cord blood transplantation seems to be a good substitute for bone marrow transplantation and has good prospects especially in children.
