Small Airway Disease in Pre-Chronic Obstructive Pulmonary Disease with Emphysema: A Cross-Sectional Study.

Rationale: Small airway disease is an important pathophysiological feature of chronic obstructive pulmonary disease (COPD). Recently, "pre-COPD" has been put forward as a potential precursor stage of COPD that is defined by abnormal spirometry findings or significant emphysema on computed tomography (CT) in the absence of airflow obstruction. Objective: To determine the degree and nature of (small) airway disease in pre-COPD using microCT in a cohort of explant lobes/lungs. Methods: We collected whole lungs/lung lobes from patients with emphysematous pre-COPD (n = 10); Global Initiative for Chronic Obstructive Lung Disease (GOLD) stage I (n = 6), II (n = 6), and III/IV (n = 7) COPD; and controls (n = 10), which were analyzed using CT and microCT. The degree of emphysema and the number and morphology of small airways were compared between groups, and further correlations were investigated with physiologic measures. Airway and parenchymal pathology was also validated with histopathology. Measurements and Main Results: The numbers of transitional bronchioles and terminal bronchioles per milliliter of lung were significantly lower in pre-COPD and GOLD stages I, II, and III/IV COPD compared with controls. In addition, the number of alveolar attachments of the transitional bronchioles and terminal bronchioles was also lower in pre-COPD and all COPD groups compared with controls. We did not find any differences between the pre-COPD and COPD groups in CT or microCT measures. The percentage of emphysema on CT showed the strongest correlation with the number of small airways in the COPD groups. Histopathology showed an increase in the mean chord length and a decrease in alveolar surface density in pre-COPD and all GOLD COPD stages compared with controls. Conclusions: Lungs of patients with emphysematous pre-COPD already show fewer small airways and airway remodeling even in the absence of physiologic airway obstruction.

A randomised phase II study of extended pleurectomy/decortication preceded or followed by chemotherapy in patients with early-stage pleural mesothelioma: EORTC 1205.

BACKGROUND: The role of surgery in pleural mesothelioma remains controversial. It may be appropriate in highly selected patients as part of a multimodality treatment including chemotherapy. Recent years have seen a shift from extrapleural pleuropneumonectomy toward extended pleurectomy/decortication. The most optimal sequence of surgery and chemotherapy remains unknown. METHODS: EORTC-1205-LCG was a multicentric, noncomparative phase 2 trial, 1:1 randomising between immediate (arm A) and deferred surgery (arm B), followed or preceded by chemotherapy. Eligible patients (Eastern Cooperative Oncology Group 0-1) had treatment-naïve, borderline resectable T1-3 N0-1 M0 mesothelioma of any histology. Primary outcome was rate of success at 20 weeks, a composite end-point including 1) successfully completing both treatments within 20 weeks; 2) being alive with no signs of progressive disease; and 3) no residual grade 3-4 toxicity. Secondary end-points were toxicity, overall survival, progression-free survival and process indicators of surgical quality. FINDINGS: 69 patients were included in this trial. 56 (81%) patients completed three cycles of chemotherapy and 58 (84%) patients underwent surgery. Of the 64 patients in the primary analysis, 21 out of 30 patients in arm A (70.0%; 80% CI 56.8-81.0%) and 17 out of 34 patients (50.0%; 80% CI 37.8-62.2%) in arm B reached the statistical end-point for rate of success. Median progression-free survival and overall survival were 10.8 (95% CI 8.5-17.2) months and 27.1 (95% CI 22.6-64.3) months in arm A, and 8.0 (95% CI 7.2-21.9) months and 33.8 (95% CI 23.8-44.6) months in arm B. Macroscopic complete resection was obtained in 82.8% of patients. 30- and 90-day mortality were both 1.7%. No new safety signals were found, but treatment-related morbidity was high. INTERPRETATION: EORTC 1205 did not succeed in selecting a preferred sequence of pre- or post-operative chemotherapy. Either procedure is feasible with a low mortality, albeit consistent morbidity. A shared informed decision between surgeon and patient remains essential.

Joint ERS/EACTS/ESTS clinical practice guidelines on adults with spontaneous pneumothorax.

BACKGROUND: The optimal management for spontaneous pneumothorax (SP) remains contentious, with various proposed approaches. This joint clinical practice guideline from the ERS, EACTS and ESTS societies provides evidence-based recommendations for the management of SP. METHODS: This multidisciplinary Task Force addressed 12 key clinical questions on the management of pneumothorax, using ERS methodology for guideline development. Systematic searches were performed in MEDLINE and Embase. Evidence was synthesised by conducting meta-analyses, if possible, or narratively. Certainty of evidence was rated with GRADE (Grading of Recommendations, Assessment, Development and Evaluations). The Evidence to Decision framework was used to decide on the direction and strength of the recommendations. RESULTS: The panel makes a conditional recommendation for conservative care of minimally symptomatic patients with primary spontaneous pneumothorax (PSP) who are clinically stable. We make a strong recommendation for needle aspiration over chest tube drain for initial PSP treatment. We make a conditional recommendation for ambulatory management for initial PSP treatment. We make a conditional recommendation for early surgical intervention for the initial treatment of PSP in patients who prioritise recurrence prevention. The panel makes a conditional recommendation for autologous blood patch in secondary SP patients with persistent air leak (PAL). The panel could not make recommendations for other interventions, including bronchial valves, suction, pleurodesis in addition to surgical resection or type of surgical pleurodesis. CONCLUSIONS: With this international guideline, the ERS, EACTS and ESTS societies provide clinical practice recommendations for SP management. We highlight evidence gaps for the management of PAL and recurrence prevention, with research recommendations made.

The Prognostic Role of the Number of Involved Structures in Thymic Epithelial Tumors: Results from the ESTS Database.

BACKGROUND: The role of the number of involved structures (NIS) in thymic epithelial tumors (TETs) has been investigated for inclusion in future staging systems, but large cohort results still are missing. This study aimed to analyze the prognostic role of NIS for patients included in the European Society of Thoracic Surgeons (ESTS) thymic database who underwent surgical resection. METHODS: Clinical and pathologic data of patients from the ESTS thymic database who underwent surgery for TET from January 2000 to July 2019 with infiltration of surrounding structures were reviewed and analyzed. Patients' clinical data, tumor characteristics, and NIS were collected and correlated with CSS using Kaplan-Meier curves. The log-rank test was used to assess differences between subgroups. A multivariable model was built using logistic regression analysis. RESULTS: The final analysis was performed on 303 patients. Histology showed thymoma for 216 patients (71.3%) and NET/thymic carcinoma [TC]) for 87 patients (28.7%). The most frequently infiltrated structures were the pleura (198 cases, 65.3%) and the pericardium in (185 cases, 61.1%), whereas lung was involved in 96 cases (31.7%), great vessels in 74 cases (24.4%), and the phrenic nerve in 31 cases (10.2%). Multiple structures (range, 2-7) were involved in 183 cases (60.4%). Recurrence resulted in the death of 46 patients. The CSS mortality rate was 89% at 5 years and 82% at 10 years. In the univariable analysis, the favorable prognostic factors were neoadjuvant therapy, Masaoka stage 3, absence of metastases, absence of myasthenia gravis, complete resection, thymoma histology, and no more than two NIS. Patients with more than two NIS presented with a significantly worse CSS than patients with no more than two NIS (CSS 5- and 10-year rates: 9.5% and 83.5% vs 93.2% and 91.2%, respectively; p = 0.04). The negative independent prognostic factors confirmed by the multivariable analysis were incomplete resection (hazard ratio [HR] 2.543; 95% confidence interval [CI] 1.010-6.407; p = 0.048) and more than two NIS (HR 1.395; 95% CI 1.021-1.905; p = 0.036). CONCLUSIONS: The study showed that more than two involved structures are a negative independent prognostic factor in infiltrative thymic epithelial tumors that could be used for prognostic stratification.

European Respiratory Society guideline on various aspects of quality in lung cancer care.

This European Respiratory Society guideline is dedicated to the provision of good quality recommendations in lung cancer care. All the clinical recommendations contained were based on a comprehensive systematic review and evidence syntheses based on eight PICO (Patients, Intervention, Comparison, Outcomes) questions. The evidence was appraised in compliance with the GRADE (Grading of Recommendations Assessment, Development and Evaluation) approach. Evidence profiles and the GRADE Evidence to Decision frameworks were used to summarise results and to make the decision-making process transparent. A multidisciplinary Task Force panel of lung cancer experts formulated and consented the clinical recommendations following thorough discussions of the systematic review results. In particular, we have made recommendations relating to the following quality improvement measures deemed applicable to routine lung cancer care: 1) avoidance of delay in the diagnostic and therapeutic period, 2) integration of multidisciplinary teams and multidisciplinary consultations, 3) implementation of and adherence to lung cancer guidelines, 4) benefit of higher institutional/individual volume and advanced specialisation in lung cancer surgery and other procedures, 5) need for pathological confirmation of lesions in patients with pulmonary lesions and suspected lung cancer, and histological subtyping and molecular characterisation for actionable targets or response to treatment of confirmed lung cancers, 6) added value of early integration of palliative care teams or specialists, 7) advantage of integrating specific quality improvement measures, and 8) benefit of using patient decision tools. These recommendations should be reconsidered and updated, as appropriate, as new evidence becomes available.

An Overview of the Use of Anti-Angiogenic Agents in the Treatment of Thymic Epithelial Tumors.

Angiogenesis significantly influences the carcinogenesis of thymic epithelial tumors (TET). Both thymomas and thymic carcinoma (TC) overexpress VEGF-A and VEGFR-1 and -2. This review aims to provide an appraisal of the use of anti-angiogenics in the treatment of TET. The literature research identified 16 studies that were deemed eligible for further analysis. Seven studies assessed the clinical efficacy of sunitinib and five studies the use of apatinib and/or anlotinib. The multicenter Japanese phase II REMORA trial investigated the efficacy of lenvatinib, which is a multi-targeted inhibitor of VEGFR, FGFR, RET, c-Kit, and other kinases. The objective response rate was 38% (25.6-52%), which is the highest documented in TET that progressed after first-line chemotherapy. Anti-angiogenic agents may be useful in the treatment of TET, which are not amenable to curative treatment. Their toxicity profile seems to be acceptable. However, angiogenesis inhibitors do not appear to have a major influence on either thymomas or TC, although multikinase inhibitors may have some effect on TC. The current evidence suggests that the most active agent is lenvatinib, whereas sunitinib could be proposed as an acceptable second-line therapy for TC. Further research concerning the combination of immune checkpoint inhibitors with anti-angiogenic drugs is warranted.

Cholesterol granuloma mimicking an anterior mediastinal tumor - a case report.

There are many different types of mediastinal masses, which makes it challenging to diagnose them. Furthermore, the clinical presentation can range from asymptomatic to life-threatening. We present the case of a 68-year-old male with an incidental finding of a tumor located in the anterior mediastinum. A computed tomography (CT) of the thorax and an 18-Fluorodeoxyglucose positron emission tomography (PET) suggested a thymoma, which is the most common primary tumor of the anterior mediastinum. The patient was scheduled for a robotic-assisted thoracoscopy (RATS) thymectomy. Both this procedure and the postoperative course were uneventful. The pathology report showed multiple cholesterol granulomas in the mediastinal fat. Furthermore, no malignancy (e.g. a thymoma) could be found. A cholesterol granuloma mimicking an anterior mediastinal tumor is extremely rare.

Navigating Diagnostic and Treatment Decisions in Non-Small Cell Lung Cancer: Expert Commentary on the Multidisciplinary Team Approach.

Non-small cell lung cancer (NSCLC) accounts for approximately one in five cancer-related deaths, and management requires increasingly complex decision making by health care professionals. Many centers have therefore adopted a multidisciplinary approach to patient care, using the expertise of various specialists to provide the best evidence-based, personalized treatment. However, increasingly complex disease staging, as well as expanded biomarker testing and multimodality management algorithms with novel therapeutics, have driven the need for multifaceted, collaborative decision making to optimally guide the overall treatment process. To keep up with the rapidly evolving treatment landscape, national-level guidelines have been introduced to standardize patient pathways and ensure prompt diagnosis and treatment. Such strategies depend on efficient and effective communication between relevant multidisciplinary team members and have both improved adherence to treatment guidelines and extended patient survival. This article highlights the value of a multidisciplinary approach to diagnosis and staging, treatment decision making, and adverse event management in NSCLC. IMPLICATIONS FOR PRACTICE: This review highlights the value of a multidisciplinary approach to the diagnosis and staging of non-small cell lung cancer (NSCLC) and makes practical suggestions as to how multidisciplinary teams (MDTs) can be best deployed at individual stages of the disease to improve patient outcomes and effectively manage common adverse events. The authors discuss how a collaborative approach, appropriately leveraging the diverse expertise of NSCLC MDT members (including specialist radiation and medical oncologists, chest physicians, pathologists, pulmonologists, surgeons, and nursing staff) can continue to ensure optimal per-patient decision making as treatment options become ever more specialized in the era of biomarker-driven therapeutic strategies.

Evaluation of Temporal Artery Duplex Ultrasound for Diagnosis of Temporal Arteritis.

BACKGROUND: Temporal arteritis or giant cell arteritis is a form of systemic inflammatory vasculitis closely associated with polymyalgia rheumatica. It may have serious systemic, neurologic, and ophthalmic consequences as it may lead to impaired vision and blindness. Definitive diagnosis is made after histopathologic analysis of a superficial temporal artery (TA) biopsy, which requires a small surgical procedure often under local anesthesia. We investigated whether a noninvasive technique such as duplex ultrasound of the TA could replace histopathological analysis. METHODS: Eighty-one patients referred to our department for TA biopsy were first screened with a duplex ultrasound for a surrounding halo and/or occlusion of the TA. Presence of visual disturbances and unilateral pain (headache and/or tongue/jaw claudication) was noted before TA biopsy. Pathological analysis was considered the gold standard. Correlation between duplex findings, symptoms, and pathology was determined by Spearman's Rho test. The predictive value of a halo and TA occlusion on duplex were determined by ROC curve analysis. RESULTS: A halo or TA occlusion was found in 16.0% and 3.7% of patients, respectively. Unilateral pain was reported in 96% of cases while 82% complained of visual disturbances. Correlation coefficients for halo and occlusion were 0.471 and 0.404, respectively (P < 0.0001), suggesting a moderate correlation between duplex and biopsy. There was no significant correlation between visual impairment or pain and histologic findings. The ROC curve analysis showed a sensitivity of 53.3% and 20.0%, and specificity of 91.9% and 100% for presence of a halo and occlusion of the TA on duplex, respectively. CONCLUSIONS: Arterial duplex is a moderately sensitive but highly specific test for exclusion of temporal arteritis. We observed a moderate correlation between these findings on duplex and histopathological analysis as a gold standard. Arterial duplex may serve as a valuable diagnostic addition to prevent unnecessary surgical procedures and can even substitute biopsy in patients where surgery is not an option.

A combined intrapleural administration of dornase alfa and tissue plasminogen activator is safe in children with empyema - A pilot study.

OBJECTIVE: There is still no consensus regarding the treatment of empyema in children. Intrapleural combination of tissue plasminogen activator and dornase alfa is a promising treatment for empyema in adults. The aim of this pilot study was to determine whether this combination is safe and successful in pediatric empyema. METHODS: Previous well children diagnosed with empyema as classified by the British Thoracic Society. After chest tube insertion, intrapleurally dornase alfa 2.5 mg for 2 days and tissue plasminogen activator 0.15 mg/kg for 3 days was given after which the chest tube was clamped for 4 h. Primary outcome was safety. RESULTS: Ten consecutive children were included (4 boys, aged 3.2 (1.3-15.0) years old). No serious adverse events were seen. One child developed urticaria but additional intervention or cessation of the trial was not needed. There was no bleeding or mortality and no additional procedures were performed. The median hospital stay after intervention was 7.5 days. CONCLUSIONS: The intrapleural treatment of dornase alfa and tissue plasminogen activator as treatment of empyema was safe in ten children with empyema. If confirmed in further studies, this combination of intrapleural therapy may improve the management of pediatric empyema.

ERS/ESTS/EACTS/ESTRO guidelines for the management of malignant pleural mesothelioma.

The European Respiratory Society (ERS)/European Society of Thoracic Surgeons (ESTS)/European Association for Cardio-Thoracic Surgery (EACTS)/European Society for Radiotherapy and Oncology (ESTRO) task force brought together experts to update previous 2009 ERS/ESTS guidelines on management of malignant pleural mesothelioma (MPM), a rare cancer with globally poor outcome, after a systematic review of the 2009-2018 literature. The evidence was appraised using the Grading of Recommendations, Assessment, Development and Evaluation approach. The evidence syntheses were discussed and recommendations formulated by this multidisciplinary group of experts. Diagnosis: pleural biopsies remain the gold standard to confirm the diagnosis, usually obtained by thoracoscopy but occasionally via image-guided percutaneous needle biopsy in cases of pleural symphysis or poor performance status. Pathology: standard staining procedures are insufficient in ∼10% of cases, justifying the use of specific markers, including BAP-1 and CDKN2A (p16) for the separation of atypical mesothelial proliferation from MPM. Staging: in the absence of a uniform, robust and validated staging system, we advise using the most recent 2016 8th TNM (tumour, node, metastasis) classification, with an algorithm for pre-therapeutic assessment. Monitoring: patient's performance status, histological subtype and tumour volume are the main prognostic factors of clinical importance in routine MPM management. Other potential parameters should be recorded at baseline and reported in clinical trials. Treatment: (chemo)therapy has limited efficacy in MPM patients and only selected patients are candidates for radical surgery. New promising targeted therapies, immunotherapies and strategies have been reviewed. Because of limited data on the best combination treatment, we emphasise that patients who are considered candidates for a multimodal approach, including radical surgery, should be treated as part of clinical trials in MPM-dedicated centres.

Local treatment of stage IIIA-N2 nonsmall cell lung cancer: surgery and/or radiotherapy.

PURPOSE OF REVIEW: Controversy exists regarding the optimal treatment of patients with stage IIIA-N2 nonsmall cell lung cancer because of its heterogeneity. Patients are at risk for both local and distant disease relapse after primary local treatment. However, there may be a window of opportunity for surgery, if mediastinal downstaging has been obtained after induction therapy. This manuscript reviews the outcome of patients treated by neo-adjuvant chemotherapy (NA-C) followed by surgery, compared with patients treated with either definitive sequential or concurrent chemoradiotherapy (cCRT), illustrated by a single-centre retrospective case series. RECENT FINDINGS: Of 53 eligible patients, 19 received NA-C and underwent surgical resection, whilst 20 and 14 received concurrent or sequential definitive CRT, respectively. A significant difference in progression-free survival favouring NA-C followed by surgery over both CRT modalities was found. However, this translated only in an overall survival benefit in comparison with sequential definitive CRT. A trend for better outcome was observed in selected surgical patients with single-level mediastinal involvement and complete resection. SUMMARY: Our case series results are consistent with the present standard of care of CRT, which restricts surgical resection to carefully selected patients. Immunotherapy will likely change the treatment paradigm.

Use of Robotics in Surgical Treatment of Non-small Cell Lung Cancer.

OPINION STATEMENT: Robotic-assisted videothoracoscopic surgery (R-VATS) has become increasingly popular and widely used since its introduction and is nowadays considered a standard treatment approach in many centres for the treatment of non-small cell lung cancer. R-VATS was initially developed to overcome the drawbacks of VATS by offering surgeons more flexibility and three-dimensional optics during thoracoscopic surgery. The effectiveness of R-VATS lobectomy regarding oncological outcomes, morbidity, mortality, and postoperative quality of life (QoL) has been shown in an increasing number of studies. More recently, these results have also been corroborated for sublobar resections, more specifically for segmentectomy. However, no well-powered, multicentre randomized trials have been performed to demonstrate the superiority of R-VATS compared with open surgery or conventional types of VATS (total VATS, uniportal VATS, etc.). The majority of the evidence currently available is based on non-randomized studies, and many studies report conflicting results when comparing R-VATS and conventional VATS. Moreover, there is a lack of data regarding the cost and the cost-efficiency of robotic surgery compared with VATS and open surgery. Current evidence suggests that R-VATS costs are higher than VATS and that a deficit can only be prevented when up to 150-300 thoracic surgery procedures are performed annually. Finally, robotic-assisted laparoscopic surgery showed better ergonomics and reduced musculoskeletal disorders compared with non-robotic laparoscopic surgery.

The Role of c-Met as a Biomarker and Player in Innate and Acquired Resistance in Non-Small-Cell Lung Cancer: Two New Mutations Warrant Further Studies.

The c-Met receptor is a therapeutically actionable target in non-small-cell lung cancer (NSCLC), with one approved drug and several agents in development. Most suitable biomarkers for patient selection include c-Met amplification and exon-14 skipping. Our retrospective study focused on the frequency of different c-Met aberrations (overexpression, amplification and mutations) in 153 primary, therapy-naïve resection samples and their paired metastases, from Biobank@UZA. Furthermore, we determined the correlation of c-Met expression with clinicopathological factors, Epidermal Growth Factor Receptor (EGFR)-status and TP53 mutations. Our results showed that c-Met expression levels in primary tumors were comparable to their respective metastases. Five different mutations were detected by deep sequencing: three (E168D, S203T, N375S) previously described and two never reported (I333T, G783E). I333T, a new mutation in the Sema(phorin) domain of c-Met, might influence the binding of antibodies targeting the HGF-binding domain, potentially causing innate resistance. E168D and S203T mutations showed a trend towards a correlation with high c-Met expression (p = 0.058). We found a significant correlation between c-MET expression, EGFR expression (p = 0.010) and EGFR mutations (p = 0.013), as well as a trend (p = 0.057) with regards to TP53 mutant activity. In conclusion this study demonstrated a strong correlation between EGFR mutations, TP53 and c-Met expression in therapy-naïve primary resection samples. Moreover, we found two new c-Met mutations that warrant further studies.

Conservative treatment of a posterior intercostal lung herniation: a case report.

Introduction patients: A rare posterior intercostal lung herniation was diagnosed after a coughing spell by computed tomography and treated conservatively. Two years later, there were no specific complications or progression of the herniation. Methods, results and conclusions: There is no consensus on the indications for surgery and optimal treatment of this disorder.

Pancreaticopleural fistula: a rare cause of pleural empyema.

Aim: Pancreaticopleural fistula (PPF) is a rare complication of acute or chronic pancreatitis. When the pancreatic duct disrupts, pancreatic fluid may leak into the retroperitoneum and fistulate into the pleural cavity. Patients usually present with thoracic complaints, making it hard to suspect an abdominal etiology. Although PPF is uncommon, one must consider this diagnosis in patients with thoracic complaints and a history of alcohol abuse or pancreatitis. Methods: We present an illustrative case and review of the literature on PPF. Results: A 47-year old man was presented with recurrent PPF due to pancreas divisum, pancreatic stones and chronic exudative pancreatitis, resulting in unilateral empyema. After initial conservative treatment, operative measures were needed. We report omentoplasty against the diaphragmatic hiatus in combination with VATS (video-assisted thoracoscopic surgery) thoracotomy with decortication and debridement as a feasible operative option for resolving PPF. Conclusion: PPF is a rare complication of pancreatitis. The diagnosis is difficult to make and can be confirmed by thoracocentesis and proper imaging, preferably MRCP. Treatment options include conservative, endoscopic (ERCP) or surgical measures. Omentoplasty positioned against the diaphragmatic hiatus is a feasible technique for closure of PPF.

Myasthenia gravis appearing after thymectomy heralding recurrent thymoma.

INTRODUCTION: Thirty to fifty percent of thymoma patients develop myasthenia gravis (MG). In 1.5-28% of cases, MG appears many years after removal of a thymoma. PATIENTS AND METHODS: We present a case report of a 72-year-old female who presented with MG four months after total thymectomy. RESULTS: A 72-year-old female patient presents with MG four months after total thymectomy. Imaging revealed a PET-positive nodule anterior to the superior vena cava. By median sternotomy, the nodule was removed at our hospital. Pathology confirmed a recurrent B2/B3 thymoma with R0 resection. No adjuvant therapy was given. Large population studies show the appearance of new-onset MG associated with recurrent thymoma in 3% of cases. CONCLUSIONS: New-onset MG postthymectomy heralds recurrent disease in 3% of cases. Thorough screening is needed in such patients.

ERS statement on harmonised standards for lung cancer registration and lung cancer services in Europe.

The European Respiratory Society (ERS) task force for harmonised standards for lung cancer registration and lung cancer services in Europe recognised the need to create a single dataset for use in pan-European data collection and a manual of standards for European lung cancer services.The multidisciplinary task force considered evidence from two different sources, reviewing existing national and international datasets alongside the results of a survey of clinical data collection on lung cancer in 35 European countries. A similar process was followed for the manual of lung cancer services, with the task force using existing guidelines and national or international recommendations for lung cancer services to develop a manual of standards for services in Europe.The task force developed essential and minimum datasets for lung cancer registration to enable all countries to collect the same essential data and some to collect data with greater detail. The task force also developed a manual specifying standards for lung cancer services in Europe.Despite the wide variation in the sociopolitical landscape across Europe, the ERS is determined to encourage the delivery of high-quality lung cancer care. Both the manual of lung cancer services and the minimum dataset for lung cancer registration will support this aspiration.
