Although various strategies for steroid withdrawal after transplantation have been attempted, there are few reports of the long-term results of steroid withdrawal regimens in kidney transplantation. Earlier, we reported on a 5-year prospective, randomized, single-center trial comparing the safety and efficacy of cyclosporine (CsA) plus mycophenolate mofetil (MMF) with that of tacrolimus (TAC) plus MMF, when steroids were withdrawn 6 months after kidney transplantation in low-risk patients. We now report the 10-year observational data on the study population. We collected data from the database of the Organ Transplantation Center, Samsung Medical Center for 5 years after completion of the original study (TAC group n = 62; CsA group n = 55). The 10-year patient survival, death-censored graft survival, and acute rejection-free survival did not differ between groups (98% vs 96%; P = 0.49, 78% vs 85%; P = 0.75 and 84% vs 76%; P = 0.14 in the TAC group vs CsA group, respectively). In low-risk patients, there was no difference in long-term patient and graft survival between TAC- and CsA-based late steroid withdrawal regimens that included MMF treatment. More long-term randomized clinical trials are needed to clarify the benefits of late steroid withdrawal in kidney transplantation.
