Histologic evaluation of allograft biopsies after lung transplantation has several limitations, suggesting that molecular assessment using tissue transcriptomics could improve biopsy interpretation. This single-center, retrospective cohort study evaluated discrepancies between the histology of transbronchial biopsies (TBBs) with no rejection (NR) and T-cell mediated rejection (TCMR) by molecular diagnosis. The accuracy of diagnosis was assessed based on response to treatment. 54 TBBs from Prague Lung Transplant Program obtained between December 2015 and January 2020 were included. Patients with acute cellular rejection (ACR) grade ≥ 1 by histology received anti-rejection treatment. Response to therapy was defined as an increase in FEV1 of ≥ 10% 4 weeks post-biopsy compared to the pre-biopsy value. Among the 54 analyzed TBBs, 25 (46%) were concordant with histology, while 29 (54%) showed discrepancies. ACR grade 0 was found in 12 TBBs (22%) and grade A1 ≥ 1 in 42 TBBs (78%). Treatment response was present in 14% in the NR group and in 50% in the TCMR group (p = 0.024). Our findings suggest that low-grade acute cellular rejection is less likely to be associated with molecular TCMR, which might better identify lung transplant recipients who benefit from therapy.

BACKGROUND: The aim of this study was to determine independent risk factors affecting postoperative morbidity and mortality after pneumonectomy for non-small cell lung cancer (NSCLC). METHODS: A review of 329 patients having pneumonectomy for NSCLC between January 1, 1998 and July 31,2012 was undertaken. Factors affecting morbidity and mortality were analyzed by univariate and multivariate analyses. RESULTS: The overall 30-day mortality rate was 5.1%. Smoking habits, chronic obstructive pulmonary disease (COPD) status, neoadjuvant therapy and obesity had no statistical influence on the short-term outcome. Coronary artery disease and respiratory failure were identified as risk factors for increased 30-day mortality (p < 0.01). Right pneumonectomy and presence of respiratory failure with mechanical ventilation increased the incidence of bronchopleural fistula (p < 0.01). CONCLUSIONS: Pneumonectomy for NSCLC carries an acceptable operative morbidity and mortality. Coronary artery disease, right pneumonectomy and respiratory failure adversely affect morbidity and mortality after this procedure.
