In one patient, a second transplantation from the haploidentical mother was also performed at relapse. No patients were in complete remission (CR) at the time of conditioning. After allo\u2010HCT, all three achieved and maintained CR. One died from sepsis and the other relapsed, received the second transplantation and achieved a second CR. EBV VL was quite high in all three at presentation and its significant reduction was observed after allo\u2010HCT. Although their backgrounds were not different from those without allo\u2010HCT, patients with allo\u2010HCT had a better outcome.<\/jats:p><jats:p><jats:bold>Conclusion:\u2002<\/jats:bold> Allo\u2010HCT might be a promising therapy for ANKL with curative potential.<\/jats:p>","DOI":"10.1111\/j.1600-0609.2008.01090.x","type":"journal-article","created":{"date-parts":[[2008,5,6]],"date-time":"2008-05-06T10:06:50Z","timestamp":1210068410000},"page":"107-111","source":"Crossref","is-referenced-by-count":26,"title":["Promising approach for aggressive NK cell leukaemia with allogeneic haematopoietic cell transplantation"],"prefix":"10.1111","volume":"81","author":[{"given":"Toshiro","family":"Ito","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hideki","family":"Makishima","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hideyuki","family":"Nakazawa","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hikaru","family":"Kobayashi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shigetaka","family":"Shimodaira","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yozo","family":"Nakazawa","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kiyoshi","family":"Kitano","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kazuyuki","family":"Matsuda","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eiko","family":"Hidaka","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fumihiro","family":"Ishida","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2008,7,18]]},"reference":[{"key":"e_1_2_5_2_2","first-page":"198","volume-title":"World Health Organization Classification of Tumors.
