Figure 2. One Year-Overall Survival aftern dUCBT in adults with<br />

malignant disorders by status of the disease at transplant.<br />

GVHD compared with that of single UCBT but without<br />

an increase in non-relapse mortality. Interestingly, in an<br />

analysis of 177 patients with acute leukemia, relapse<br />

was significantly <strong>lo</strong>wer for early stage (CR1-2) patients<br />

who received two UCB units, suggesting a greater GVL<br />

effect. DFS was 40% and 51% for single and double<br />

unit recipients, respectively (p=0.35). 33<br />

The Eurocord group has published results of single<br />

and dUCBT for patients with lymphoid malignancies. 34<br />

Relapse incidence was reduced for patients transplanted<br />

with a dUCBT compared with those patients transplanted<br />

with a single unit. Recently, in a preliminary and<br />

unpublished analysis, Eurocord in collaborat<strong>io</strong>n with<br />

the Acute Leukemia Working party of EBMT have compared<br />

the outcomes after dUCBT (n=213) with single<br />

UCBT (sUCBT=378) in adult patients with acute<br />

mye<strong>lo</strong>id or lymphoblastic leukemia in remiss<strong>io</strong>n. There<br />

were some differences between the two groups:<br />

dUCBT recipients were heavier (median weight: 69kg<br />

vs. 64 kg, p
