Abstract

Hemorrhagic cystitis (HC) is a major complication after allogeneic stem cell transplantation (allo-SCT) and can be life threatening. To analyze risk factors and prognosis, we retrospectively reviewed 249 cases receiving allo-SCT in our institution. Median age was 47 years (13-72 years). Disease status at SCT was progressive in 73 cases. Conditioning was myeloablative (MAC) in 146 cases. Acute graft-versus-host disease (aGVHD) grade II-IV treated with prednisolone occurred in 82 cases, and cytomegalovirus (CMV) was reactivated in 91 cases. HC was reported in 47 cases at a median of 35 days (7-469 days) after SCT, and 34 (72.3%) cases recovered after a median of 19.5 days (2-252 days). In univariate analysis, the identified risk factors for HC included age over 45 years, progressive disease status, MAC, aGVHD treated with prednisolone, and CMV reactivation. In multivariate analysis, older age, MAC, and CMV remained independent predictors (hazard ratios: 2.35, 3.50, and 2.87). In patients with severe HC, percentage recovery was lower (3 in 13 cases; 23.1%) and the median duration was longer (54 days) than in those with moderate HC (31 in 36 cases; 86.1%, 17 days, P < 0.01). Treatment-related mortality was also higher (59.1%, P = 0.03) and overall survival was poorer (16.7%, P < 0.01) at 1 year after SCT. Prospective studies should be started considering prophylactic antiviral administration in high-risk patients such as those identified in this study.
