Abstract
Background The key issues for performing lung volume reduction surgery (LVRS) is the identification of the target zones. Recently introduced three-dimensional computed tomography rendering methods are used to identify the morphological distribution and its severity of lung emphysema by densitometry. We demonstrate a new software for emphysema imaging and show the pre- and post-operative results in patients undergoing LVRS planned based on this new technology. Methods A real-time three-dimensional image analysis software system was used pre- and 3 months post-operatively in five patients with heterogeneous emphysema and a single patient with homogeneous morphology scheduled for LVRS. Focus was on low attenuation areas with <950 HU, distribution on both lungs and the value of the three-dimensional images for planning surgery. Functional outcome was assessed by pulmonary function tests after 3 months. Results Five patients underwent bilateral LVRS and one patient had unilateral LVRS. All patients showed a median increase in forced expiratory volume in 1 s of 70% (range 30–120%), compared with baseline values. Hyperinflation (expressed as residual volume/total lung capacity ratio) was reduced by 30% (range 5–32%). In the patients with heterogeneous emphysema, the pre- and post-operative computed tomography scans and the densitometries showed a decrease in low attenuation areas by 23% (right side) and by 17% (left side), respectively. Conclusion We demonstrate three-dimensional computed tomography-rendered images for planning personalised remodelling of hyperinflated lungs using LVRS. This user-friendly software has the potential to assist surgeons and interventional pulmonologists to select patients and to visualise target areas in LVRS procedures. New, user-friendly software with 3D CT-rendered images can be used for planning personalised remodelling of hyperinflated lungs using LVRShttps://bit.ly/3fbICn2

Abstract
Abstract
Myasthenia gravis is a rare but archetypic autoimmune disease that is characterized by the autoantibody-mediated disruption of the neuromuscular junction leading to a skeletal muscle weakness. Immunomodulatory treatment options for Myasthenia gravis patients are largely unspecific, include suppression of the entire immune compartment and are often accompanied by severe side effects.
In order to identify novel biomarkers for more targeted and effective therapeutic approaches, we combined high-dimensional mass and flow cytometry with supervised and unsupervised machine-learning algorithms. Analysis of the peripheral immune compartment of Myasthenia gravis patients and healthy controls revealed a cellular immune signature consisting of inflammatory memory T helper cells with a defined cytokine profile. The abundance of the identified leukocytes in the blood strongly correlated with the patients clinical disease activity, far better than auto-Ab titers. Moreover, we were able to locate T cells with the defined signature enriched in the inflamed thymus of Myasthenia gravis patients – the key organ for the induction and maintenance of the autoimmune disease. Lastly, using an unbiased pattern recognition approach, we identified lymphomas in a subset of Myasthenia gravis patients, further highlighting the potential of the applied analysis tools.

Abstract
BACKGROUND Primary pulmonary sarcoma (PPS) is a rare malignant lung neoplasm, and there is very little medical evidence about treatment of PPS. The aim of this study is to clarify the clinical characteristics and therapeutic outcome of patients who underwent surgical resection for PPS. METHODS We retrospectively reviewed the records of patients who underwent surgical resection for PPS in our institution between 1995 and 2014. Cases who only underwent biopsy were excluded. RESULTS A total of 24 patients (18 males, 6 females), with a median age of 60 (interquartile range: 44-67) years, were analyzed. The surgical procedures performed in these patients were pneumonectomy (n = 10), lobectomy (n = 11), and wedge resection (n = 3). Complete resection was achieved in 16 patients. The pathological stages (tumor, node, metastases lung cancer classification, 8th edition) of the patients were I (n = 4), II (n = 12), III (n = 2), and IV (n = 5), and there were four cases of lymph node metastasis. The 5-year overall survival rate of the patients was 50% (95% confidence interval [CI]: 29-72). Adverse prognostic factors for overall survival were incomplete resection (hazard ratio [HR]: 4.4, 95% CI: 2.1-42), advanced pathological stage (HR 14, 95% CI: 2.8-66), higher pathological grade (HR 4.5, 95% CI: 1.2-17), and tumor size ≥ 7 cm (HR 4.7, 95% CI: 1.1-21). CONCLUSIONS Our series of PPS revealed that incomplete resection, advanced pathological stage, higher pathological grade, and tumor size were unfavorable factors for long-term survival.

Abstract
OBJECTIVES Pulmonary hypertension (PH) is considered a contraindication for lung volume reduction surgery (LVRS). Because, it has been reported that endobronchial lung volume reduction may have a beneficial effect without increased mortality in patients with emphysema and PH, we evaluated its effect on PH in patients undergoing LVRS. METHODS From January 2014 until June 2016, 119 LVRSs were performed at Zurich University Hospital. PH was a contraindication for patients with homogeneous emphysema but was acceptable for those with heterogeneous emphysema. Thirty patients underwent echocardiography before and after LVRS, 10 of whom had preoperative systolic pulmonary artery pressures >35 mmHg and 20 of whom had normal systolic pulmonary artery pressure. The effect of LVRS on pulmonary artery pressure, lung function and survival was analysed. RESULTS Ninety-day mortality for all 30 patients was 0, and the postoperative course did not differ significantly between the 2 groups. In patients with PH, the median systolic pulmonary artery pressure decreased from 41 mmHg [interquartile range (IQR) 39-47] to 37 mmHg (IQR 36-38, P = 0.04). These patients had an improvement of forced expiratory volume in 1 s from the median 27% predicted (IQR 23-34) to 33% (IQR 28-40, P = 0.007) 3 months postoperatively. CONCLUSIONS If further confirmed in other cohorts, mild to moderate PH may no longer be considered a contraindication for LVRS in patients with heterogeneous emphysema.

Abstract
Background Radiotherapy is recommended as primary local therapy for inoperable patients with non-small cell lung cancer (NSCLC). We hypothesized that selected patients with advanced emphysema could be candidates for surgery and improved functional outcome might result in addition to low mortality and morbidity and successful cancer control when sublobar resection in a lung volume reduction surgery (LVRS) concept is applied. Methods All patients with NSCLC and severe emphysema who underwent cancer resection in a LVRS concept between 2003 and 2015 were included for analysis. Postoperative 90-day mortality, complications, survival and lung function with forced expiratory volume in one second pre-operatively and three months postoperatively served as endpoints. Results Fourteen patients were included. Three procedures were bilateral and eleven unilateral, eight have been performed with thoracoscopy and six with conversion to an open procedure due to adhesions. In ten patients, tumor resection was atypical and in four patients an anatomic segmentectomy was performed. All patients had lung volume reduction. Prolonged air leak occurred in three patients. Perioperative 90-mortality was zero. Median pre-operative forced expiratory volume in one second was 32.5% and increased to 37% (P=0.002) 3 months following surgery. Three and 5-year survival rates were 50% and 35%, respectively. Conclusions Sublobar resection of NSCLC combined with LVRS in patients with severely impaired lung function due to emphysema can be performed with low mortality and morbidity making it an alternative treatment modality to radiotherapy. This approach allows cancer resection in marginal patients and improves emphysema symptoms simultaneously.

Abstract
The aim of lung volume reduction surgery (LVRS) for patients suffering from severe emphysema is to improve lung function and palliate dyspnea. Careful patient selection in a multidisciplinary approach in a high-volume center is mandatory for a successful outcome. Pulmonary complications including air leak and pneumonia as well as cardiac complications are the most common complications after LVRS. The following article will focus on most common complications observed after LVRS and review the management strategies to improve surgical outcome.

Abstract
Lung volume reduction surgery (LVRS) for symptomatic patients with advanced emphysema was proven to be successful in a large randomized multi-center trial (NETT) and in several smaller randomized single center trials. This evidence primarily concerns patients with heterogeneous, upper-lobe predominant emphysema and low exercise tolerance within certain selection criteria regarding lung function values. As the most important effect of LVRS is generated by reducing the hyperinflation, even patients with homogeneous emphysema morphology profit from the procedure. Simultaneously, by removing distended and functionless areas in heterogeneous emphysema, also patients with seriously impaired diffusion capacity, moderate pulmonary arterial hypertension, a history of previous LVRS and alpha-1-antitrypsin-deficiency (AATD) can be considered as candidates for (re-)-LVRS. This article summarizes indications for LVRS in these various subtypes of emphysema patients.

Abstract
Purpose: Utilization of donation after circulatory death (DCD) donors has the potential to decrease donor shortage in lung transplantation (LTx). This study reviews the long-term outcome of LTx from DCD donors. Methods: We included all consecutive DCD (Maastricht Category III) and all donations after brain death (DBD) donor lung transplants at our Center performed between January 2012 and February 2017. Data were analyzed comparing the two groups in regard of survival after LTx as primary outcome. Results: Median withdrawal to cardiac arrest time was 17 min (interquartile range [IQR]: 11.5–20.5). Median cardiac arrest to cold perfusion was 32 min (IQR: 24.5–36.5). Primary graft dysfunction (PGD) grade 3 at T72 occurred in three recipients. Chronic lung allograft dysfunction (CLAD) led to death in two cases. In DCD group, there was no 90-day mortality. In DCD, group 1- and 3-year survival rates were 100% and 80%. In DBD group, 1- and 3-year survival rates were 85% and 69% (p = 0.4). Conclusions: Our report confirmed the comparable outcome from DCD donors compared with DBD donors. Utility of DCD donors is a safe option to overcome donor shortage.

Abstract
Modern Aspects of Lung Cancer Surgery Abstract. Surgery is still an inherent part of the treatment of non-small cell lung cancer. This article summarizes various aspects of the surgical treatment of early and locally advanced stages of lung cancer. Minimally invasive techniques for lung cancer resection - video- or robotic-assisted - are today standard for early stages. Perioperative mortality is below 1 % and the oncological outcome is equal to open surgery. The learning curve is at 50 VATS lobectomies in a program with a minimum of 25 VATS lobectomies/year to obtain satisfying results. In specialized centers, Locally advanced tumors can be resected technically and oncologically safe, with acceptable morbidity and mortality rates. With careful patient selection and planning, 5-year survival rates can be as high as 48 %.

Abstract
BACKGROUND Due to an increased life expectancy in a healthy aging population and a progressive incidence of lung cancer, curative pulmonary resections can be performed even in octogenarians. The present study aims to investigate whether surgery is justified in patients reaching the age of 80 years and older who undergo resection for non-small cell lung cancer (NSCLC). METHODS In this retrospective multi-centre analysis, the morbidity, mortality and long-term survival of 88 patients (24 females) aged ≥80 who underwent complete resection for lung cancer between 2000 and 2013 were analysed. Only fit patients with few comorbidities, low cardiopulmonary risk, good quality of life and a life expectancy of at least 5 years were included. RESULTS Curative resections from three thoracic surgery centres included 61 lobectomies, 9 bilobectomies, 6 pneumonectomies and 12 segmentectomies or wide wedge resections with additional systematic mediastinal lymphadenectomy in all cases. Final histology revealed squamous cell carcinoma [33], adenocarcinoma [41], large cell carcinoma [5] or other histological types [9]. Lung cancer stage distribution was 0 [1], I [53], II [17] and IIIA [14]. The overall 90-day mortality was 1.1%. The median hospitalisation and chest drainage times were 10 days (range, 5-27 days) and 5 days (range, 0-17 days), respectively. Thirty-six patients were complication-free (41%). In particular, pulmonary complications occurred in 25 patients (28%). In addition, 23 patients (26%) developed cardiovascular complications requiring medical intervention, while 24 patients (27%) had cerebrovascular complications, urinary tract infection and others. The median survival time was 51 months (range, 1-110 months), and the 5-year overall survival reached 45% without significance between tumour stages. CONCLUSIONS Curative lung resections in selected octogenarians can be safely performed up to pneumonectomy for all tumour stages with a perioperative mortality, morbidity, and 5-year survival rate comparable to younger cohorts.

Abstract
Background and Objectives: There is a paucity of data concerning the impact of the sedation technique used for endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) on diagnostic accuracy. The aim of this retrospective study was to compare the diagnostic accuracy of EBUS-TBNA in deep and moderate sedations, and to investigate other possible determinants of diagnostic accuracy in three lymph node locations (mediastinal, subcarinal, and hilar). Materials and Methods: The first consecutive patients at our institution undergoing EBUS-TBNA for selective sampling in deep sedation were compared with the first consecutive patients in moderate sedation between 2006 and 2014. Diagnoses based on EBUS-TBNA were compared with those on surgical or radiological follow-up. Results: In a total of 232 patients, the overall diagnostic accuracy for correct diagnosis at the mediastinal, subcarinal, and hilar locations irrespective of the sedation technique was 91%, 93%, and 92%, respectively. At the three mentioned lymph node locations, overall diagnostic accuracy of EBUS-TBNA in deep sedation compared to moderate sedation was 88.5% and 95.5% (P = 0.3), 93.2 and 93.6% (P = 0.9), and 88.6 and 94.0% (P = 0.4), respectively. Conclusions: The sedation technique does not seem to influence the diagnostic accuracy of EBUS-TBNA.
