Outcomes of Lung Transplantation in Patients With Combined Pulmonary Fibrosis and Emphysema: A Single-Center Experience.

BACKGROUND

Combined pulmonary fibrosis and emphysema (CPFE) is a distinct clinical entity that can progress to end-stage lung disease. Patients with CPFE may develop pulmonary hypertension and face a predicted 1-year mortality of 60%. Lung transplantation is the only curative therapeutic option for CPFE. This report describes our experience after lung transplantation in patients with CPFE.

METHODS

This retrospective, single-center study describes short- and long-term outcomes for adult patients who underwent lung transplant for CPFE.

RESULTS

The study included 19 patients with explant pathology-proven diagnosis of CPFE. The patients were transplanted between July 2005 and December 2018. Sixteen recipients (84%) had pulmonary hypertension before transplant. Of the 19 patients, 7 (37%) had primary graft dysfunction at 72 hours post-transplant. 1-, 3-, and 5-year freedom from bronchiolitis obliterans syndrome was 100%, 91% (95% CI, 75%-100%), and 82% (95% CI, 62%-100%), respectively. One-, 3-, and 5-year survival was 94% (95% CI, 84%-100%), 82% (95% CI, 65%-100%), and 74% (95% CI, 54%-100%), respectively.

CONCLUSION

Our experience demonstrates the safety and feasibility of lung transplant for patients with CPFE. Significant morbidity and mortality without lung transplant coupled with favorable post-transplant outcomes merit prioritization of CPFE in the Lung Allocation Score algorithm for lung transplant candidacy.
