HCT was performed in the following centers: Minneapolis (57), Duke (47), Manchester (29), Dublin (23), Lyon (15), Utrecht, (12), London (11), Marseille (3), Barcelona (4), Madrid (2), Israel (1), Argentina (1), Japan (2), Ghent (4), Nancy (1), Paris (11), Padua (1), Monza (9) Prague (4), Helsinki (1), Australia (1), New Zealand (1), Hanover (7), Stockholm (1), Zurich (1), Moscow (2), Cincinnati (2), Vienna (1), Jena (1), Leiden (1), Swansea (1), and Houston (1).
Of these 105 patients, 53 were T-cell–depleted. According to the HLA, T-cell–depleted HCT was performed in 10/47 (HLA 10/10) and 43 of 55 patients with HLA-mismatched UD.
