Selection of patients who may benefit from extracorporeal life support (ECLS) as a bridge to lung transplant (LTx) is crucial. The aim was to assess if validated prognostic scores could help in selecting patients who may benefit from ECLS-bridging predicting their outcomes. Clinical data of patients successfully ECLS-bridged to LTx from 2009 to 2021 were collected from two European centers. For each patient, we calculated Sequential Organ Failure Assessment (SOFA), Simplified Acute Physiology Score III (SAPS III), Acute Physiology and Chronic Health Evaluation II (APACHE II), before placing ECLS support, and then correlated with outcome. Median values of SOFA, SAPS III, and APACHE II were 5 (IQR 3-9), 57 (IQR 47.5-65), and 21 (IQR 15-26). In-hospital, 30 and 90 days mortality were 21%, 14%, and 22%. SOFA, SAPS III, and APACHE II were analyzed as predictors of in-hospital, 30 and 90 days mortality (SOFA C-Index: 0.67, 0.78, 0.72; SAPS III C-index: 0.48, 0.45, 0.51; APACHE II C-Index: 0.49, 0.45, 0.52). For SOFA, the score with the best performance, a value ≥9 was identified to be the optimal cut-off for the prediction of the outcomes of interest. SOFA may be considered an adequate predictor in these patients, helping clinical decision-making. More specific and simplified scores for this population are necessary.

OBJECTIVE Pleural adhesions (PLAs) have been shown to be a possible risk factor for air leak after lung volume reduction surgery (LVRS), but the relevance of PLA for lung function outcome remains unclear. We analyzed our LVRS cohort for the influence of PLA on short-term (ie, prolonged air leak) and long-term outcomes. METHODS Retrospective observational cohort study with 187 consecutive patients who underwent LVRS from January 2016 to December 2019. PLA were defined as relevant if they were distributed extensively at the dorsal pleura; were present in at least at 2 areas, including the dorsal pleura; or present extensively at the mediastinal pleura. In patients with bilateral emphysema, bilateral LVRS was performed preferentially. The objectives were to quantify the association of PLA and rate of prolonged air leak (chest tube >7 days), and the association of PLA with postoperative exacerbations and with forced expiratory volume in 1 second 3 months postoperatively. The associations were quantified with odds ratios for binary outcomes, and with between-group differences for continuous outcomes. To account for missing observations, 100-fold multiple imputation was used. RESULTS PLAs were found in 46 of 187 patients (24.6%). There was a 32.6% rate of prolonged air leak (n = 61), mean chest tube time was 7.84 days. A total of 94 (50.3%) LVRSs were unilateral and 93 were bilateral. There was evidence for an association between PLA and the rate of prolonged air leak (odds ratio, 2.83; 95% CI, 1.36 to 5.89; P = .006). There was no evidence for an association between PLA and postoperative exacerbations (odds ratio, 1.11; 95% CI, 0.5 to 2.45; P = .79). There was no evidence for an association between PLA and forced expiratory volume in 1 second (estimate -1.52; 95% CI -5.67 to 2.63; P = .47). Both unilateral and bilateral LVRS showed significant postoperative improvements in forced expiratory volume in 1 second by 27% (8.43 units; 95% CI, 3.66-13.12; P = .0006) and by 28%

The coronavirus disease 2019 (COVID-19) pandemic has had a severe impact on oncological and thoracic surgical practice worldwide. In many hospitals, the care of COVID-19 patients required a reduction of elective surgery, to avoid viral transmission within the hospital, and to save and preserve personnel and material resources. Cancer patients are more susceptible to severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection and are at an increased risk of a severe course of disease. In many patients with lung cancer, this risk is further increased owing to comorbidities, older age and a pre-existing lung disease. Surgical resection is an important part of the treatment in patients with early stage or locally advanced non-small cell lung cancer, but the treatment of these patients during the COVID-19 pandemic becomes a challenging balance between the risk of patient exposure to SARS-CoV-2 and the need to provide timely and adequate cancer treatment despite limited hospital capacities. This manuscript aims to provide an overview of the surgical treatment of lung cancer patients during the COVID-19 pandemic including the triage and prioritisation as well as the surgical approach, and our own experience with cancer surgery during the first pandemic wave. We furthermore aim to highlight the risk and potential consequences of delayed lung cancer treatment due to the deferral of surgery, screening appointments and follow-up visits. With much attention being diverted to COVID-19, it is important to retain awareness of cancer patients, maintain oncological surgery and avoid treatment delay during the pandemic.

BACKGROUND An inadequate donor left atrial cuff is a rare technical issue after graft procurement for lung transplantation. With regard to the shortage of suitable donor organs for lung transplantation, these organs should be surgically reconstructed to avoid the loss of an organ and a futile intervention in the critically ill recipient. CASE PRESENTATION We report a case of a 62-year old patient who underwent bilateral sequential lung transplantation for chronic obstructive pulmonary disease. During isolated lung procurement, the right inferior pulmonary vein was circumferentially transsected and separated from the right superior pulmonary and middle lobe veins. Subsequently, a reconstruction of the left atrial cuff with an acellular biological patch was performed to complete the atrium anastomosis. The patient experienced an uneventful postoperative recovery and a follow-up ventilation/perfusion scan showed normal perfusion of the right lower lobe. CONCLUSIONS This case demonstrates that reconstruction of an inadequate left atrial cuff with a biological patch is feasible and allows for an adequate venous drainage and therefore normal transplant organ function.

OBJECTIVES Lung volume reduction (LVR) is an efficient and approved treatment for selected emphysema patients. There is some evidence that repeated LVR surgery (LVRS) might be beneficial, but there are no current data on LVRS after unsuccessful bronchoscopic LVR (BLVR) with endobronchial valves (EBVs). We hypothesize good outcome of LVRS after BLVR with valves. METHODS In this study, we retrospectively investigated all patients who underwent LVRS between 2015 and 2019 at 2 centres after previous unsuccessful EBV treatment. They were further divided into subgroups with patients who never achieved the intended improvement after BLVR (primary failure) and patients whose benefit was fading over time due to the natural development of emphysema (secondary failure). Patients with severe air leak after BLVR and immediate concomitant LVRS and fistula closure thereafter were analysed separately. RESULTS A total of 38 patients were included. Of these, 19 patients had primary failure, 15 secondary failure and 4 were treated as an emergency due to severe air leak. At 3 months after LVRS, forced expiratory volume in 1 s had improved significantly by 12.5% (P = 0.011) and there was no 90-day mortality. Considering subgroups, patients with primary failure after BLVR seem to profit more than those with secondary failure. Patients with severe air leak after BLVR did not profit from fistula closure with concomitant LVRS. CONCLUSIONS LVRS after previous BLVR with EBVs can provide significant clinical improvement with low morbidity, although results might not be as good as after primary LVRS.

BACKGROUND: Cadaveric lobar lung transplantation (L-LTx) is developed to overcome donor-recipient size mismatch. Controversial short- and long-term outcomes following L-LTx have been reported compared to full-sized lung transplantation (F-LTx). This study reports long-term outcomes after L-LTx. METHODS: We reviewed patients undergoing lung transplantation (LTx) between 2000 and 2016. The decision to perform L-LTx was made based mainly on donor-recipient height discrepancy and visual assessment of donor lungs. Predicted donor-recipient total lung capacity (TLC) ratio was calculated more recently. Primary outcome was overall survival. RESULTS: In all, 370 bilateral LTx were performed during the study period, among those 250 (67%) underwent F-LTx and 120 (32%) underwent L-LTx, respectively. One- and 5-year survival rates were 85% vs. 90% and 53% vs. 63% for L-LTx and F-LTx, respectively (p = 0.16). Chronic lung allograft dysfunction (CLAD)-free survival at 5 years was 48% in L-LTx vs. 51% in F-LTx recipients (p = 0.89), respectively. Age, intraoperative extracorporeal membrane oxygenation (ECMO) use, intensive care unit (ICU) stay, and postoperative renal replacement therapy (RRT) were significant prognostic factors for survival using multivariate analysis. CONCLUSIONS: Overall survival and CLAD-free survival following L-LTx were comparable to F-LTx. Given the ongoing donor organ shortage, cadaveric L-LTx remains as an important resource in LTx.

BACKGROUND We aimed to analyse the nodal spread of our non-small cell lung cancer pN2 cohort according to tumour location, the possible implications of an unusual spreading pattern, and other factors influencing postoperative survival after anatomical lung resection. METHODS In this retrospective observational study, clinical data was collected for 124 consecutive non-small cell lung cancer (NSCLC) patients with a pathological N2 (stage IIIA or B) undergoing anatomical lung resection at our institution between 2001 and 2010. Cox regression was used to analyse independent predictors of 5-year overall survival and recurrence-free survival. RESULTS A total of 105 patients were included in the final analysis. Tumour location in the right upper lobe and middle lobe  was significantly more often associated with involvement of lymph node stations 2 and 4 than NSCLC in the right lower lobe (station 2: right upper vs right lower lobe, p = 0.001 and middle vs right lower lobe, p = 0.038; station 4: right upper vs right lower lobe, p<0.001 and middle vs right lower lobe, p = 0.056), while tumours in the right upper lobe showed significantly less involvement of stations 7 and 8 compared with right lower lobe tumours (station 7 p <0.001, station 8 p = 0.004). Left sided tumours in the upper lobe had significantly more involvement of station 5 compared to lower lobe tumours (p = 0.009). However, atypical lymphatic nodal zone involvement did not emerge as a significant predictor of survival. Lymphovascular invasion was the only independent prognostic factor for 5-year overall survival (hazard ratio [HR] 2.10, p = 0.015) and recurrence-free survival (HR 1.68, p = 0.049) when controlled for adjuvant therapy. CONCLUSION Lymphovascular invasion was identified as the only independent prognostic factor for 5-year overall survival and recurrence-free survival in our pathologically proven N2 NSCLC cohort when controlled for adjuvant therapy.
