[Comparison of clinical features of hemorrhagic cystitis after haploidentical and matched sibling donor allogeneic hematopoietic stem cell transplantation].

To compare incidence and clinical features of hemorrhage cystitis (HC) after haploidentical donor (HID) allogeneic hematopoietic stem cell transplantation (HSCT) and matched sibling donor (MSD) HSCT. Medical records of 609 (including 406 HID-HSCT and 203 MSD-HSCT cases) hematologic malignancies patients treated with HSCT undergoing myeloablative conditioning regimen from January 2011 to December 2012 were analyzed retrospectively. HC occurred 183 in HID and 17 ones in MSD respectively. The cumulative incidence of HC in HID group was higher than in MSD group[ (45.6±2.5) % (8.5±2.0) %, (2)=77.331, <0.001], and the cumulative incidence of severe HC (grade 3-4) in HID cases was also higher than in MSD ones[ (11.2±1.9) % (2.1±1.1) %, (2)=12.883, <0.001]. All HCs were occurred within 180 days in both groups. The median time to onset in two groups were 27 days after HSCT (range 0-177 days) and 29 days after HSCT (range 6-72 days) respectively (=0.766) . The median duration of HC in two groups were 21 days (range 3-157 days) and 13 days (range 5-67 days) , respectively (=0.182) . The total efficiency of treatment in two groups were 69.9% and 70.6% respectively ((2)=0.003, =1.000) . The cumulative incidences of HC and severe HC were higher in HID cases than in MSD ones. The median time to onset and median duration of HC and therapeutic outcome between HID and MSD were comparable.
