RESUMO
BACKGROUND: To perform more pancreas transplantation (PTx), our center sometimes performs pancreas transplantation for candidates ranked sixth place or lower. In this study, we analyzed the outcomes of PTx performed in our center to compare the outcomes of higher- and lower-ranked candidates. METHODS: Seventy-two cases in which PTx was performed at our center were divided into 2 groups according to the candidate's rank. Cases in which PTx was performed for candidates up to fifth place were classified into the higher rank candidate group (HRC group; n = 48), whereas PTx for candidates who were ranked sixth place or lower were classified into the lower rank candidate group (LRC group; n = 24). The outcomes of PTx were retrospectively compared. RESULTS: Although the LRC group included a greater number of older donors (age ≥60 years), a greater number of donors with deteriorated renal function, and a greater number of HLA mismatches, the 1- and 5-year patient survival rates in the HRC group were 91.6% and 91.6%, respectively, compared with 95.8% and 87.0%, respectively, in the LRC group (P = .755). In terms of both pancreas and kidney graft survival, there were no significant differences between the 2 groups. Additionally, there were no significant differences between the 2 groups regarding the glucagon stimulation test and 75 g OGTT results, insulin independence rate, HbA1c, or serum creatinine level after transplantation. CONCLUSIONS: In Japan, where there is a severe donor shortage, the performance of transplantation for lower-ranked candidates would increase the number of opportunities for patients to receive PTx.
