Adult recipients of umbilical cord blood transplants after nonmyeloablative preparative regimens.

Journal Article (Clinical Trial;Journal Article)

We report the outcome of 13 patients with advanced malignancies who underwent nonmyeloablative conditioning therapy followed by infusion of partially matched unrelated cord blood cells. The median age of these patients was 49 years, and their median weight was 65.7 kg. The median nucleated cell dose infused was 2.07 x 10(7)/kg. Eight of the 13 patients demonstrated donor chimerism between 4 weeks and 6 months, and subsequent conversion to full donor chimerism was achieved in 5 patients. Three patients were alive and free of disease at 158 to 1054 days, with a median survival of 288 days after transplantation. The 100-day event-free survival is 69%, and overall survival is 77%. At 1 year, the event-free and overall survival was 43%. Treatment-related mortality observed within the first 100 days after transplantation was low: 1 previously extensively pretreated patient died of multiorgan failure. This result provides a basis for further exploring this potentially curative approach to selected patients who lack matched related or unrelated hematopoietic stem cell donors.
