Association between the pancreas transplantation and survival of patients with diabetes: A single center experience.

Pancreas transplantation is considered a therapeutic option for patients with complicated diabetes mellitus. In this study, we compared survival rate between patients on the waiting list for pancreas transplant alone(PTA), simultaneous pancreas-kidney(SPK) transplant, and pancreas after kidney(PAK) transplant and transplant recipients. A total of 503 patients (PTA:n = 116; SPK:n = 303; PAK:n = 84) and 280 PT recipients (PTA:n = 89; SPK:n = 155; PAK:n = 36) were retrospectively analyzed at our center between February 2000 and December 2015; 11.9%(60/503) of the patients on the waiting list and 4.3%(12/280) of the PT recipients died. The overall survival rate was higher in the waiting list group for the first year (99.3% vs. 97.8%), after which it was significantly higher in PT group (p = 0.039). The overall relative risk of all-cause mortality for transplant recipients was 2.145(p = 0.285) for PTA, 0.688(p = 0.735) for PAK, however,0.361 (p = 0.012) for SPK compared with that for the waiting list patients. SPK transplant recipients had considerable higher survival benefits, despite the relatively long waiting period, especially after 1 year. In addition, PTA and PAK can also be considered as a treatment option as patient survival was not poor.
