Abstract

BACKGROUND:

The donor organs available for lung transplantation remain far fewer than the number of recipients. Therefore, it is of primary importance to optimize this resource, especially by carefully selecting potential recipients. The diagnosis of end-stage diseases referred for transplantation is mainly based on clinical/radiologic assessment and rarely on histology.

METHODS:

A clinicopathologic study was performed on 175 patients who underwent lung transplantation over a 12-year period (1995 to 2007). Diagnoses on native lungs were compared with referral diagnoses to assess the presence of discrepancies. In particular, major discrepancies included complete mismatch between referral and pathologic diagnoses and other additional findings likely to affect patient management.

RESULTS:

Major discrepancies were found in 18 of 175 cases (10%). The highest percentage of discordance was found in diffuse parenchymal lung diseases, more frequently idiopathic pulmonary fibrosis (IPF). In the majority of IPF and other non-IPF idiopathic forms, there was often an imprecise nosographic definition of the diseases. Unsuspected additional findings included Aspergillus and mycobacterial infections, carcinomas and carcinoids. Short-term survival is significantly lower in patients with discrepancies than in those without.

CONCLUSIONS:

On the basis of the high rate and importance of discrepancies, more accurate and repeated clinicopathologic investigations should be planned in the waiting list period.
