Risk Factors of Late-Onset Hemorrhagic Cystitis after Allogeneic Hematopoietic Stem Cell Transplantation].

To analyze the risk factors for late-onset hemorrhagic cystitis (LOHC) after allogeneic hematopoietic stem cell transplantation (allo-HSCT), the risk factors for the progression of LOHC to severe LOHC, and the effect of LOHC on survival. The clinical data of 300 patients who underwent allo-HSCT at the First Affiliated Hospital of Chongqing Medical University from January 2015 to December 2021 were retrospectively analyzed. The relevant clinical parameters that may affect the occurance of LOHC after allo-HSCT were selected for univariate and multivariate analysis. Then, the differences in overall survival (OS) and progression-free survival (PFS) between different groups were analyzed. The results of multivariate analysis showed that the independent risk factors for LOHC after allo-HSCT were as follows: age≤45 years old (P =0.039), intensified conditioning regimen with fludarabine/cladribine and cytarabine (P =0.002), albumin≤30 g/L on d30 after transplantation (P =0.007), CMV-DNA positive (P =0.028), fungal infection before transplantation (P =0.026), and the occurrence of grade Ⅱ - Ⅳ aGVHD (P =0.006). In the transplant patients who have already developed LOHC, the occurance of LOHC within 32 days after transplantation (P =0.008) and albumin≤30 g/L on d30 after transplantation (P =0.032) were independent risk factors for the progression to severe LOHC. The OS rate of patients with severe LOHC was significantly lower than that of patients without LOHC (P =0.041). For the patients aged≤45 years old and with intensified conditioning regimen, it is necessary to be vigilant about the occurrence of LOHC; For the patients with earlier occurrence of LOHC, it is necessary to be vigilant that it develops into severe LOHC. Early prevention and treatment of LOHC are essential. Regular monitoring of CMV-DNA and albumin levels, highly effective antiviral and antifungal therapies, and prevention of aGVHD are effective measures to prevent the occurrence and development of LOHC.
