Are there any age specification for liver transplantation?

Age limits: Each transplant center determines this based on medical criteria.

Not really: There is no real age limitation for liver transplantation. However, it depends on patients medical and functional conditions. For example, patient in his/her 70's with cirrhosis and early liver cancer, but otherwise fully functional, no other significant medical condition, can can be considered for liver transplant. Having said that, to my knowledge, no one had transplant above age 80.
