Observation on the efficacy of liposomal doxorubicin intensive preconditioning regimen and allogeneic hematopoietic stem cell transplantation for treatment of leukemia / 白血病·淋巴瘤

ABSTRACT

Objective:To investigate the efficacy of liposomal doxorubicin intensive preconditioning regimen and allogeneic hematopoietic stem cell transplantation (allo-HSCT) in treatment of leukemia.Methods:The data of 20 patients with intensive preconditioning regimen allo-HSCT who were admitted to Shenzhen Second People's Hospital from January 2016 to June 2017 were retrospectively analyzed. The transplantation effect, occurrence of complications and prognosis of patients were analyzed.Results:The median time of granulocyte engraftment was 17 d (13-23 d); the median time of platelet engraftment was 22.5 d (minimum 13 d, maximum >90 d). The acute graft-versus-host disease (GVHD) and chronic GVHD occurred in 2 cases and 1 case, respectively. Eight cases occurred hemorrhagic cystitis, 15 cases occurred Epstein-Barr viremia, 8 cases occurred cytomegaloviremia, 1 case occurred sepsis, 1 case occurred acute liver injury, and 2 cases occurred fungal pneumonia. The median follow-up time was 31.7 months (0.8-53.8 months). One patient died of intracranial infection on the 25th day after transplantation; 3 patients relapsed during the follow-up period, and 2 of them died; the other 16 patients carried 100% donor genes during the follow-up period.Conclusions:The liposomal doxorubicin intensive preconditioning regimen and allo-HSCT have a good effect on leukemia. Increasing the intensity of pretreatment does not increase the treatment-related adverse reactions. The incidence rates of Epstein-Barr viremia and cytomegaloviremia are high, but they are improved after active treatment.
