High treatment-related mortality and high graft failure rate are serious concerns in HLA-mismatched umbilical cord blood (UCB) transplantation with myeloablative conditioning. We conducted a prospective trial of dual UCB transplantation using modified myeloablation consisting of total body irradiation (TBI; 1350 cGy) and fludarabine (160 mg/m2). Twenty-seven patients (median age, 33 years; range, 20–58 years) with hematologic malignancies were enrolled. The median combined cryopreserved total nucleated cell (TNC) dose was 4.3 × 107/kg (range, 3.2–7.7 × 107/kg). The cumulative incidences of neutrophil (≥500/μl) and platelet (≥50,000/μl) engraftment were 80% (95% confidence interval (CI), 58–91%) and 68% (95% CI, 46–83%), respectively. Among engrafted patients, a single cord blood unit was predominant by 100 days post transplantation. A higher cryopreserved and infused TNC dose and infused CD3+ cell dose were significant factors associated with the predominant UCB unit (P = 0.032, 0.020, and 0.042, respectively). Treatment-related mortality and relapse rates at 2 years were 28% (95% CI, 12–47%) and 20% (95% CI, 7–37%), respectively. Cumulative incidences of grades II–IV and grades III–IV acute GVHD were 37% (95% CI, 20–55%) and 11% (95% CI, 3–26%), respectively, and that of chronic GVHD was 31% (95% CI, 15–49%). With a median follow-up of 23 months, overall and disease-free survival rates at 2 years were 58% (95% CI, 34–75%) and 52% (95% CI, 29–70%), respectively. This study supports the use of TBI 1350cGy/fludarabine as an alternative to conventional myeloablative conditioning for dual UCB transplantation.
