Impact of Recipient Age on Outcomes After Pancreas Transplantation

Few reports have provided the ages of pancreas transplant recipients. The aim of this study was to determine whether recipient age affects survival of pancreatic grafts after transplantation.

We analyzed 73 patients who had undergone pancreas transplantation at our institution from August 2001 to March 2020 and assessed the effects of recipient age on pancreas graft survival within 5 years after pancreas transplantation.

The cutoff value for recipient age established by receiver operating characteristic curve was 35 years. The pancreas graft survival rate of recipients aged 35 years or younger (1, 3, and 5 years: 72.9%, 41.7%, and 41.7%, respectively) was significantly lower than that of recipients aged over 35 years (1, 3, and 5 years: 93.2%, 88.4%, and 88.4%, respectively). Multivariate Cox hazard regression analysis showed that recipient age 35 years or younger (hazard ratio = 3.60; 95% confidence interval, 1.04-12.50; P = .044) and solitary pancreas transplantation (hazard ratio = 10.72; 95% confidence interval, 2.72-42.28; P < .001) were significant risk factors for pancreas graft loss within 5 years.

Our data suggest that younger recipient age is a risk factor for pancreas graft loss after transplantation.
