Patient history. Displayed are each patient's diagnosis, type of transplantation (MUD, matched unrelated donor; MRD, matched related donor), and time elapsing between significant events: transplantation, relapsed disease (RD)34 donor lymphocyte infusion (DLI), graft-versus-host disease (GvHD) symptoms, GvHD treatment, and death. Four patients (TK04, TK05, TK06, and TK08) achieved complete remission, one had progressive disease (TK07), and three patients died prior to response evaluation after DLI (TK01, TK02, and TK03).
