Hemorrhagic cystitis (HC) is a common toxicity of preparative regimens for bone marrow transplantation (BMT). Severe HC often requires prolonged and expensive hospitalization, and occasionally can result in death. To investigate the risk factors for severe HC, we conducted a retrospective study among 1908 patients who received BMTs at the University of Minnesota during 1974 to 1993. A previous report from our institution reported on 977 of these patients. We identified all patients with genitourinary complication within 100 days post-BMT from the BMT database. Medical charts for these patients were reviewed to determine whether the patient had HC and also the grade of HC. A total of 208 HC cases were identified during the study period. Of them, 92 patients had severe HC, an incidence of 5% (95% CI = 4-6%). We found that grade II-IV graft-versus-host disease (RR = 2.56; 95% CI = 1.43-4.56), use of busulfan (RR = 2.69; 95% CI = 1.35-5.35), and age at transplant (RR = 2.20; 95% CI = 1.27-3.81, for age of 10-30 compared to age of 0-9) were related to an increased risk of HC. In contrast, transplant year was inversely associated with the risk of HC (trend test, P < 0.01). We did not find any significant difference in HC with the use of prophylactic Mesna.

Cells from Fanconi anemia (FA) patients are hypersensitive to alkylating agents and radiation traditionally used as conditioning regimens for marrow cell transplantation, and patients experience serious toxicities. To reduce toxicities, we used progressively lower doses of cyclophosphamide (CY) for conditioning. Here, we report the results in 43 FA patients who received marrow transplantation from HLA-matched related donors (37 siblings and 6 other relatives). Conditioning consisted of 15 mg CY/kg/day for 4 days along with Mesna. Methotrexate and cyclosporine were given for graft-versus-host disease (GVHD) prophylaxis. Forty patients (93%) are alive with a median follow-up of 3.7 (range 0.6 to 7.9) years. One patient with primary graft failure was successfully retransplanted. Three of 4 patients with late graft failures were retransplanted, and 2 of those are alive; 1 died before a second marrow graft. Twelve patients including 3 with rejection had cytogenetic abnormalities in their marrow cells before transplantation. Acute grade II-III and chronic GVHD (aGVHD, cGVHD) were seen in 17% and 28.5% of patients, respectively. These results confirm and extend our previous observations that conditioning with 60 mg CY/kg allows for sustained engraftment of HLA-matched related marrow grafts in most FA patients and is associated with low toxicity, low incidences of aGVHD and cGVHD, and excellent long-term survival.
