Lung transplantation for emphysema: Impact of age on short- and long-term survival


Inci, Ilhan; Schuurmans, Macé; Ehrsam, Jonas; Schneiter, Didier; Hillinger, Sven; Jungraithmayr, Wolfgang; Benden, Christian; Weder, Walter (2015). Lung transplantation for emphysema: Impact of age on short- and long-term survival. European Journal of Cardio-Thoracic Surgery, 48(6):906-909.

Abstract

OBJECTIVES: Overall, emphysema (EMP) is the most common indication for lung transplantation. The majority of patients present with chronic obstructive pulmonary disease (COPD) and less frequently with alpha-1 antitrypsin deficiency (A1ATD). We analysed the results of lung transplants performed for EMP in order to identify the impact of age on short- and long-term outcome.
METHODS: A retrospective analysis was undertaken of the 108 consecutive lung transplants for EMP performed at our institution from November 1992 to August 2013 (77 COPD, 31 A1ATD). Retransplantations were excluded.
RESULTS: The median age was 56 years (range 31-68). Thirty-day mortality rate was 3.7%. One- and 5-year survival rates in COPD and A1ATD recipients were comparable (P = 0.8). The 1- and 5-year survival rates for recipients aged <60 years old were significantly better than the age group of ≥60 years (91 and 79 vs 84 and 54%, P = 0.05). Since 2007, the 1- and 5-year survival for these two age groups were 96 and 92 vs 86 and 44%, respectively, P = 0.04, log-rank test). For the following parameters, we were not able to find any difference to affect survival rates: use of intraoperative extracorporeal membrane oxygenation, waiting list time, sex, graft size reduction, body mass index and diagnosis. In multivariate analysis, age at transplantation (≥60 years old) (HR 2.854; 95% confidence interval (CI) 1.338-6.08, P = 0.008) and unilateral lung transplantation (HR 15.2; 95% CI 3.2-71.9, P = 0.009) were independent risk factors for mortality.
CONCLUSIONS: COPD and A1ATD recipients have similar overall long-term survival. Recipients aged ≥60 years and unilateral lung transplants were risk factors for mortality.
