A randomized study of the efficacy of adjuvant local graft irradiation following renal transplantation.
A prospective randomized study investigating the effectiveness of adjuvant local graft irradiation (LGI) following renal transplantation was performed at Georgetown University Hospital from 1983 until 1988. One hundred and thirty-eight patients were enrolled in the study with 117 patients receiving cadaver kidney transplantations and 21 patients receiving living related kidney transplantations. Seventy-one patients were randomized to receive adjuvant local graft irradiation consisting of 600 cGy in four fractions with chemical immunosuppression whereas the remaining 67 patients received chemical immunosuppression only (control group). The two groups were comparable at entry with respect to potentially important prognostic variables. Median follow-up for all patients was 30 months. The 3-year actuarial allograft success rate was 75% and 68% for the local graft irradiation and control groups, respectively. A nonsignificant trend favoring the irradiated group was noted. Subgroup analysis of the 21 recipients of kidneys from living related donors suggested an improvement in allograft survival for the local graft irradiation arm. Cadaver allograft survival was not significantly different between the two treatment arms. There was no apparent benefit in kidney function or time to the first rejection episode in the group receiving local graft irradiation.
