Effect of Age on Liver Transplantation Recipient Outcomes: Two Centers' Experience

Liver diseases epidemiology has changed with advances in perioperative care. Transplantation at large centers is favorable among older and younger recipients. Local limitations on transplantation for recipients older than 65 years were cancelled in 2014. This study evaluates the effects of age on the transplantation outcome of Israeli patients in the era after removal of the limitations on recipient age.

This retrospective analysis examined prospective data on patients older than 18 years who underwent liver or liver-kidney transplantation between 2014 and 2019 at 2 transplantation centers. Patients were divided into 4 age groups (group 1: ≤59 years; group 2: 60-64 years; group 3: 65-69 years; and group 4: ≥70 years). Each group's associations of pretransplantation factors with outcome and survival were examined.

Two hundred sixty-one recipients underwent 269 transplantations (mean age: 53 ± 12.61 y). There were 181 male (67.8%) and 88 female recipients (67.28%). Overall, 207 patients (79.6%) survived ≥12 months. One-year survival rates were 82.9%, 73.2%, 71.4%, and 93.8% for groups 1 to 4, respectively (not statistically significant; P = .11). One-year graft survival was similar between groups. More patients with chronic obstructive pulmonary disease, diabetes mellitus, or ischemic heart disease tended to survive <12 months. Cardiovascular complication was more common in older groups and affected survival.

Patient age alone should not be used to deny access to transplantation, which could benefit older nonfrail individuals. However, risk factors such as male sex, chronic obstructive pulmonary disease, ischemic heart disease, diabetes mellitus, and concomitant kidney-liver transplantation should be carefully considered.
