Elderly Living Donor Liver Transplant Recipients Over 60 Years Old at a Japanese Single Center

• The outcomes of elderly (more than 60 years old) living donor liver transplant (LDLT) recipients were evaluated.
• No significant differences were found between the elderly and nonelderly recipient groups.
• No independent risk factors were identified for survival less than 1 year or more than 1 year.
• Favorable results may have partly depended on exclusion of patients from LDLT who were in poor physical status.
• Good results may also have been due in part to selecting a right lobe graft based on LDLT indication criteria.

BackgroundAmong living donor liver transplant (LDLT) recipients, the number of elderly individuals has been increasing because of longer survival due to the improvement of treatment for hepatic diseases such as hepatitis C (HCV). Here we report the outcomes of living donor recipients over the age of 60 years.Materials and MethodsIn 76 adult LDLT patients at our institution before September 2015, there were 21 recipients over 60 years old. We divided all of the recipients into 2 groups (“elderly” recipient group >60 years of age [n = 21], and a “nonelderly” recipient group <60 years [n = 55]), and we investigated outcomes in each group.ResultsThe graft survival rates in the elderly group were 89.9% at 1 year, 89.9% at 3 years, 83.0% at 5 years, and 83.0% at 10 years. The graft survival rates in the nonelderly group was 91.1% at 1 year, 85.2% at 3 years, 82.8% at 5 years, and 82.9% at 10 year. There was no significant difference between the 2 age groups. In the elderly group, 3 patients died (2 patients had HCV recurrence and 1 patient had fungal infection in the brain, leading to a fatal subarachnoid hemorrhage). In the nonelderly group, 4 of 10 patients died of graft failure due to the graft size being too small.ConclusionElderly patients, at the end stage of liver failure, are likely very frail and may have latent infections. Careful examination for latent infections before LDLT should be carefully performed in regard to indications for LDLT, which might reach satisfactory outcomes as in nonelderly LDLT recipients. Even if elderly patients are approved for transplantation, very careful management is needed.
