Unrelated mismatched cord blood transplantation in an adult with secondary AML.

Umbilical cord blood (CB) has been widely used for related and unrelated transplants in pediatric patients. We present the case of an adult with secondary AML who received an unrelated, one-antigen mismatched CB transplant due to the lack of a matched donor. The patient was a 26-year-old female (35 kg/bw) who had received an autologous bone marrow transplant for Hodgkin's disease in April 1994 and, 6 months later, developed secondary MDS (RAEB, 46, XX, -7, +mar), which slowly evolved into acute myelogenous leukemia. In May 1995, she was transplanted with a 165 ml CB unit containing a total of 1.6 x 10(9) nucleated cells, 11 x 10(6) CD34+ cells and 7.2 x 10(5) CFU-GM. GVHD prophylaxis consisted of standard CsA and methotrexate. Myeloid engraftment occurred on day +28 (PMN > 500) and full donor chimerism was confirmed twice (on days +33 and +56) by means of cytogenetics and DNA microsatellite analysis. Erythroid and megakaryocytic engraftment was documented by immunohistochemical analysis of a bone marrow biopsy on day +40, showing the presence of erythroblastic islands and isolated CD61+ immature cells. The patient did not develop GVHD but died on day +56 from idiopathic interstitial pneumonia and multiorgan failure. To our knowledge, this is one of the first case reports of unrelated mismatched CB transplantation in an adult.
