Background:
Patients with end-stage idiopathic pulmonary fibrosis (IPF) are increasingly having bilateral rather than single-lung transplantation.
Objective:
To compare survival after single and bilateral lung transplantation in patients with IPF.
Design:
Analysis of data from the United Network of Organ Sharing registry.
Setting:
Transplantation centers in the United States.
Patients:
3327 patients with IPF who had single (2146 patients [64.5%]) or bilateral (1181 patients [35.5%]) lung transplantation between 1987 and 2009.
Measurements:
Survival times and causes of death after lung transplantation. Selection bias was accounted for by multivariate risk adjustment, propensity score risk adjustment, and propensity-based matching.
Results:
Median survival time was longer after bilateral lung transplantation than single-lung transplantation (5.2 years [CI, 4.3 to 6.7 years] vs. 3.8 years [CI, 3.6 to 4.1 years]; P < 0.001). However, survival times for the 2 procedures did not differ after adjustment for baseline differences, with adjusted hazard ratios (HRs) for mortality with bilateral transplantation ranging from 0.89 (95% CI, 0.79 to 1.02) to 0.96 (CI, 0.77 to 1.20) in different analyses. Bilateral lung transplantation seemed to result in harm within the first year (HR, 1.18 [CI, 0.98 to 1.42]) but survival benefit thereafter (HR, 0.72 [CI, 0.59 to 0.87]). Primary graft failure was a more common cause of death among patients who had bilateral rather than single-lung transplantation (3.7% vs. 1.9%; P = 0.002). Cancer was a more common cause of death among patients who had single rather than bilateral lung transplantation (unadjusted HR for death among single vs. bilateral transplant recipients, 3.60 [CI, 2.16 to 6.05]; P <0.001).
Limitation:
Causes of death were ascertained without an adjudication committee and must be interpreted cautiously.
Conclusion:
Survival did not differ between patients who had single and bilateral lung transplantation. Single-lung transplantation confers short-term survival benefit but long-term harm, whereas bilateral transplantation confers short-term harm but long-term survival benefit.
