Abstract
INTRODUCTION Recent advances in the treatment of locally advanced NSCLC have led to changes in the standard of care for this disease. For the selection of the best approach strategy for each patient, it is necessary the homogenization of diagnostic and therapeutic interventions, as well as the promotion of the evaluation of patients by a multidisciplinary oncology team. OBJECTIVE Development of an expert consensus document with suggestions for the approach and treatment of locally advanced NSCLC leaded by Spanish Lung Cancer Group GECP. METHODS Between March and July 2023, a panel of 28 experts was formed. Using a mixed technique (Delphi/nominal group) under the guidance of a coordinating group, consensus was reached in 4 phases: 1. Literature review and definition of discussion topics 2. First round of voting 3. Communicating the results and second round of voting 4. Definition of conclusions in nominal group meeting. Responses were consolidated using medians and interquartile ranges. The threshold for agreement was defined as 85% of the votes. RESULTS New and controversial situations regarding the diagnosis and management of locally advanced NSCLC were analyzed and reconciled based on evidence and clinical experience. Discussion issues included: molecular diagnosis and biomarkers, radiologic and surgical diagnosis, mediastinal staging, role of the multidisciplinary thoracic committee, neoadjuvant treatment indications, evaluation of response to neoadjuvant treatment, postoperative evaluation, and follow-up. CONCLUSIONS Consensus clinical suggestions were generated on the most relevant scenarios such as diagnosis, staging and treatment of locally advanced lung cancer, which will serve to support decision-making in daily practice.

Abstract
BACKGROUND Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is considered the investigation of choice for sampling mediastinal nodes. A major drawback of EBUS-TBNA is its lower diagnostic yield for lymphoma and benign diseases. EBUS-guided mediastinal cryobiopsy (EBUS-MCB) is a novel technique that provides larger nodal biopsy samples, with an acceptable safety profile. In this study, we aimed to evaluate the diagnostic yield of EBUS-MCB in patients with an inconclusive rapid on-site evaluation (ROSE). METHODS This is a prospective study of patients who underwent EBUS-TBNA for undiagnosed mediastinal lymphadenopathy. Patients in whom ROSE did not yield a diagnosis (nondiagnostic ROSE) or ROSE revealed scanty atypical cells (inadequate ROSE) were subjected to EBUS-MCB. The diagnostic yield, adequacy, and complications of EBUS-MCB were analyzed. RESULTS Of the 196 patients undergoing EBUS-TBNA, 46 patients underwent EBUS-MCB. Thirty-two cases underwent EBUS-MCB for a nondiagnostic ROSE. EBUS-MCB confirmed the diagnosis in 19/32 (59.3%) cases. The additive diagnostic yield of EBUS-MCB over EBUS-TBNA was 43.7% (14/32 cases). In all 14 cases where EBUS-MCB was performed for an inadequate ROSE, the material obtained by EBUS-MCB was adequate for ancillary studies. The most common complication observed was a minor bleed in 13 cases. CONCLUSION EBUS-MCB has a diagnostic yield of 59.3% when performed in cases with a nondiagnostic EBUS-ROSE. The tissue obtained by EBUS-MCB is adequate for ancillary studies. We propose EBUS-MCB as an additional diagnostic step in cases with an inconclusive ROSE while performing EBUS-TBNA. Larger studies are, however, needed before EBUS-MCB can be incorporated in the diagnostic algorithm for the evaluation of mediastinal lesions.

Deep Learning Using Endobronchial-Ultrasound-Guided Transbronchial Needle Aspiration Image to Improve the Overall Diagnostic Yield of Sampling Mediastinal Lymphadenopathy. Diagnostics (Basel) 2022; 12:diagnostics12092234. [PMID: 36140635 PMCID: PMC9497910 DOI: 10.3390/diagnostics12092234] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2022] [Revised: 08/23/2022] [Accepted: 09/13/2022] [Indexed: 11/17/2022] Open
Abstract
Lung cancer is the biggest cause of cancer-related death worldwide. An accurate nodal staging is critical for the determination of treatment strategy for lung cancer patients. Endobronchial-ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) has revolutionized the field of pulmonology and is considered to be extremely sensitive, specific, and secure for lung cancer staging through rapid on-site evaluation (ROSE), but manual visual inspection on the entire slide of EBUS smears is challenging, time consuming, and worse, subjective, on a large interobserver scale. To satisfy ROSE’s needs, a rapid, automated, and accurate diagnosis system using EBUS-TBNA whole-slide images (WSIs) is highly desired to improve diagnosis accuracy and speed, minimize workload and labor costs, and ensure reproducibility. We present a fast, efficient, and fully automatic deep-convolutional-neural-network-based system for advanced lung cancer staging on gigapixel EBUS-TBNA cytological WSIs. Each WSI was converted into a patch-based hierarchical structure and examined by the proposed deep convolutional neural network, generating the segmentation of metastatic lesions in EBUS-TBNA WSIs. To the best of the authors’ knowledge, this is the first research on fully automated enlarged mediastinal lymph node analysis using EBUS-TBNA cytological WSIs. We evaluated the robustness of the proposed framework on a dataset of 122 WSIs, and the proposed method achieved a high precision of 93.4%, sensitivity of 89.8%, DSC of 82.2%, and IoU of 83.2% for the first experiment (37.7% training and 62.3% testing) and a high precision of 91.8 ± 1.2, sensitivity of 96.3 ± 0.8, DSC of 94.0 ± 1.0, and IoU of 88.7 ± 1.8 for the second experiment using a three-fold cross-validation, respectively. Furthermore, the proposed method significantly outperformed the three state-of-the-art baseline models, including U-Net, SegNet, and FCN, in terms of precision, sensitivity, DSC, and Jaccard index, based on Fisher’s least significant difference (LSD) test (p<0.001). For a computational time comparison on a WSI, the proposed method was 2.5 times faster than U-Net, 2.3 times faster than SegNet, and 3.4 times faster than FCN, using a single GeForce GTX 1080 Ti, respectively. With its high precision and sensitivity, the proposed method demonstrated that it manifested the potential to reduce the workload of pathologists in their routine clinical practice.

Abstract
OBJECTIVES To develop and validate a CT nomogram and a radiomics nomogram to differentiate mass-forming chronic pancreatitis (MFCP) from pancreatic ductal adenocarcinoma (PDAC) in patients with chronic pancreatitis (CP). METHODS In this retrospective study, the data of 138 patients with histopathologically diagnosed MFCP or PDAC treated at our institution were retrospectively analyzed. Two radiologists analyzed the original cross-sectional CT images based on predefined criteria. Image segmentation, feature extraction, and feature reduction and selection were used to create the radiomics model. The CT and radiomics models were developed using data from a training cohort of 103 consecutive patients. The models were validated in 35 consecutive patients. Multivariable logistic regression analysis was conducted to develop a model for the differential diagnosis of MFCP and PDAC and visualized as a nomogram. The nomograms' performances were determined based on their differentiating ability and clinical utility. RESULTS The mean age of patients was 53.7 years, 75.4% were male. The CT nomogram showed good differentiation between the two entities in the training (area under the curve [AUC], 0.87) and validation (AUC, 0.94) cohorts. The radiomics nomogram showed good differentiation in the training (AUC, 0.91) and validation (AUC, 0.93) cohorts. Decision curve analysis showed that patients could benefit from the CT and radiomics nomograms, if the threshold probability was 0.05-0.85 and > 0.05, respectively. CONCLUSIONS The two nomograms reasonably accurately differentiated MFCP from PDAC in patients with CP and hold potential for refining the management of pancreatic masses in CP patients. KEY POINTS • A CT nomogram and a computed tomography-based radiomics nomogram reasonably accurately differentiated mass-forming chronic pancreatitis from pancreatic ductal adenocarcinoma in patients with chronic pancreatitis (CP). • The two nomograms can monitor the cancer risk in patients with CP and hold promise to optimize the management of pancreatic masses in patients with CP.

Abstract
Lung cancer is 1 of the leading causes of cancer-related deaths and bronchoscopy is an essential tool for the diagnosis. The diagnostic yield varies based on the characteristics of the lesion and bronchoscopic techniques employed. There is limited data regarding outcomes of patients suspected of thoracic malignancies with a non-diagnostic initial bronchoscopy. The goal of the study was to evaluate the outcomes of patients with a non-diagnostic bronchoscopy for suspected thoracic malignancies and to evaluate variables predictive of a diagnostic bronchoscopy.Retrospective analysis of adult patients at BronxCare Hospital Center who underwent bronchoscopy for suspected thoracic malignancy. The study period was January 2012 to February 2019. Exclusion criteria included patients who underwent only inspection bronchoscopy or bronchoalveolar lavage as the diagnostic yield for malignancy with these techniques is low. All other bronchoscopic procedures were included that is, endobronchial biopsies, transbronchial biopsies, and endobronchial ultrasound guided-transbronchial needle aspiration. Bronchoscopy was considered diagnostic when a specific histopathological diagnosis was established.311 patients underwent bronchoscopy to rule out malignancy. A diagnosis was obtained in 153 (49.2%) patients, 81 (52.9%) had primary lung cancer and 14 (9.15%) other malignancies. 158 (50.8%) patients had initial non-diagnostic bronchoscopy; 86 (54.43%) were lost to follow up. Of the remaining 72 (45.57%) patients, radiological resolution or stability was observed in 51 (70.8%) patients. Primary lung cancer was found in 13 (18.05%) patients and other malignancies in 5 (6.94%). Predictive of a diagnostic bronchoscopy was the performance of endobronchial biopsies and endobronchial ultrasound guided-transbronchial needle aspiration.This study highlights some of the barriers to the timely diagnosis of thoracic malignancies. Following patients with a non-diagnostic procedure as well as all those patients with diagnosed malignancies it of the utmost importance. In patients available for follow up, close to 25% of additional cases with treatable malignancy could be identified and patients diagnosed with cancer could receive timely treatment.

Abstract
BACKGROUND Infectious complications after endobronchial ultrasound-guided transbronchial biopsy with a guide sheath (EBUS-GS-TBB) are serious in that they may delay or change scheduled subsequent therapy. The aim of this study was to identify risk factors for infection after EBUS-GS-TBB. RESEARCH QUESTION What are the risk factors for infection after EBUS-GS-TBB? STUDY DESIGN AND METHODS We retrospectively reviewed the medical records of 1,045 consecutive patients who had undergone EBUS-GS-TBB for peripheral lung lesions between January 2013 and December 2017 at Fujita Health University Hospital. We evaluated the following risk factors for infectious complications after EBUS-GS-TBB: relevant patient characteristics (age and comorbidities), lesion size, CT scan features of target lesion (intratumoral low-density areas [LDAs] and cavitation), stenosis of responsible bronchus observed by bronchoscopy, and laboratory data before EBUS-GS-TBB (WBC count and C-reactive protein concentration). RESULTS Forty-seven of the study patients developed infectious complications (24 with pneumonia, 14 with intratumoral infection, three with lung abscess, three with pleuritis, and three with empyema), among whom the complication caused a delay in cancer treatment in 13 patients, cancellation of cancer treatment in seven patients, and death in three patients. Multivariate analysis showed that cavitation (P = .007), intratumoral LDAs (P < .001), and stenosis of responsible bronchus observed by bronchoscopy (P < .001) were significantly associated with infectious complications after EBUS-GS-TBB. Prophylactic antibiotics had been administered to 13 patients in the infection group. Propensity matched analysis could not show significant benefit of prophylactic antibiotics in preventing post-EBUS-GS-TBB infections. INTERPRETATION Cavitation, LDAs for CT scan features of target lesions, and stenosis of responsible bronchus observed by bronchoscopy are risk factors of post-EBUS-GS-TBB infection. In the cohort, prophylactic antibiotics failed to prevent infectious complications.

Abstract
Whilst adequate for most existing pathological tests, formalin is generally considered a poor DNA preservative and use of alternative fixatives may prove advantageous for molecular testing of tumour material; an increasingly common approach to identify targetable driver mutations in lung cancer patients. We collected paired PAXgene® tissue-fixed and formalin-fixed samples of block-sized tumour and lung parenchyma, Temno-needle core tumour biopsies and fine needle tumour aspirates (FNAs) from non-small cell lung cancer resection specimens. Traditionally processed formalin fixed paraffin wax embedded (FFPE) samples were compared to paired PAXgene® tissue fixed paraffin-embedded (PFPE) samples. We evaluated suitability for common laboratory tests (H&E staining and immunohistochemistry) and performance for downstream molecular investigations relevant to lung cancer, including RT-PCR and next generation DNA sequencing (NGS). Adequate and comparable H&E staining was seen in all sample types and nuclear staining was preferable in PAXgene® fixed Temno tumour biopsies and tumour FNA samples. Immunohistochemical staining was broadly comparable. PFPE samples enabled greater yields of less-fragmented DNA than FFPE comparators. PFPE samples were also superior for PCR and NGS performance, both in terms of quality control metrics and for variant calling. Critically we identified a greater number of genetic variants in the epidermal growth factor receptor gene when using PFPE samples and the Ingenuity® Variant Analysis pipeline. In summary, PFPE samples are adequate for histopathological diagnosis and suitable for the majority of existing laboratory tests. PAXgene® fixation is superior for DNA and RNA integrity, particularly in low-yield samples and facilitates improved NGS performance, including the detection of actionable lung cancer mutations for precision medicine in lung cancer samples.

Abstract
INTRODUCTION Endobronchial ultrasound-guided trans-bronchial needle aspiration (EBUS-TBNA) has emerged as a minimally invasive, highly accurate technique for sampling intrathoracic lymph nodes. The complication rate after EBUS-TBNA is estimated at between 0.22% to 1.44%. Analysis of the different series of EBUS-TBNA reveals that mediastinal haematoma has not been described as a complication. CASE REPORT We describe the case of a 65-year-old-man who underwent an EBUS-TBNA of a subcarinal lymph node. Few days later the patient presented with haemoptysis of average amount associated with a haematoma in the subcarinal area seen on CT-scan. It was suggested that puncture of a bronchial artery occurred during passage of the needle. This complication occurred during the change from treatment by low molecular weight heparin to antivitamine K. The patient was monitored in the intensive care unit and received medical treatment only. CONCLUSIONS This patient developed a complication after an EBUS-TBNA that is rarely described and probably under diagnosed. This complication occurred during the change between two anticoagulant treatments, which requires special attention in this particular context.

Abstract
This editorial comments on the study by Paravati et al., which reported on the incidence of occult regional lymph node metastases in PET-CT T1T2N0 non-small cell lung cancer (NSCLC) patients. A central location and the size of the tumor were shown to be the strongest predictors of the risk of occult nodal disease. Authors comment that in view of limitations of modern imaging, as well as the reported negative predictive value (NPV) of invasive staging methods, the choice of therapeutic options as the extent of surgery (lobectomy or sublobar resection) or radiotherapy [stereotactic body radiation therapy (SBRT) or conformal radiotherapy (RT) with some forms of elective nodal irradiation (ENI)] should consider tumor's characteristics and not be based only on imaging and invasive staging modalities.

Abstract
Pericardial recesses are formed at sites of reflection of the visceral to parietal pericardium around the great vessels of the mediastinum. Identification at endobronchial ultrasound (EBUS) of a "high-riding" superior pericardial recess, masquerading as a lower paratracheal lymph node, has previously been reported. Although the potential for the posterior pericardial recess to be seen in the subcarinal region on computed tomography has been described in the radiology literature, its identification with EBUS has not. We report a case where the posterior pericardial recess was seen with EBUS in the lower subcarinal region adjacent to the bronchus intermedius. It can be clearly differentiated from a lymph node or vascular structure due to its hypoechoic appearance and lack of a color Doppler signal. Bronchoscopists should be aware of the potential to image the posterior pericardial recess with EBUS in the subcarinal region, to avoid confusion at the time of endoscopy.

Endobronchial ultrasound-guided transbronchial needle aspiration for diagnosing mediastinal lymphadenectasis: a cohort study from a single center. CLINICAL RESPIRATORY JOURNAL 2015; 11:159-167.

Abstract
OBJECTIVE Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is commonly used for clinical diagnosis of mediastinal lymphadenectasis. This study aimed to evaluate the diagnostic significance of EBUS-TBNA for mediastinal lymphadenectasis in a large single center. METHODS A total of 846 patients who were not definitively diagnosed with mediastinal lymphadenectasis underwent EBUS-TBNA were retrospectively analyzed in this study. RESULTS In total, 842 patients underwent EBUS-TBNA successfully. There were 589 patients with malignancy, including squamous carcinoma (118 cases; 20.6%), adenocarcinoma (187 cases; 32.7%) and small cell carcinoma (88 cases; 15.4%). A total of 253 patients were diagnosed with benign disease, including tuberculosis (111 cases; 43.9%) and sarcoidosis (93 cases; 36.7%). The diagnostic sensitivity of lung cancer, tuberculosis and sarcoidosis were 94.4%, 81.1% and 51.6%, respectively. The overall sensitivity of EBUS-TBNA was 92.0%. N2 stage in lung cancer patients who were diagnosed by EBUS-TBNA was significantly higher than other stages. The positive rate of targeted puncture is high for the lymph nodes whose short-axis diameters were larger than 1 cm. CONCLUSION The operation risk of EBUS-TBNA is relatively small. In diseases complicated by mediastinal lymphadenectasis, malignant diseases are most, and benign diseases mainly are granulomatous. EBUS-TBNA is a valuable diagnostic technique in patients with mediastinal lymphadenectasis whose diagnosis have not been determined.

Abstract
A wide variety of pathologic processes, both benign and malignant, affect the central airways. These processes may be classified into 4 distinct groups: anatomic variants, lesions that result in focal or diffuse airway narrowing, and those that result in multinodular airway disorder. Key to the accurate assessment of the central airways is meticulous imaging technique, especially the routine acquisition of contiguous high-resolution, 1-mm to 1.5-mm images. These images enable high-definition axial, coronal, and sagittal reconstructions, as well as advanced imaging techniques, including minimum intensity projection images and virtual bronchoscopy. Current indications most commonly include patients presenting with signs and symptoms of possible central airway obstruction, with or without hemoptysis. In addition to diagnosing airway abnormalities, computed tomography (CT) also serves a critical complementary role to current bronchoscopic techniques for both diagnosing and treating airway lesions. Advantages of CT include noninvasive visualization of the extraluminal extent of lesions, as well as visualization of airways distal to central airways obstructions. As discussed and illustrated later, thorough knowledge of current bronchoscopic approaches to central airway disease is essential for optimal correlative CT interpretation.

Abstract
Lung cancer is one of the most prevalent types of cancer in the world. A complete diagnosis of lung cancer involves tissue acquisition for pathological subtype, molecular diagnosis and accurate staging of the disease to guide appropriate therapy. Real-time endobronchial ultrasound transbronchial needle aspiration (EBUS-TBNA) is minimally invasive and relatively safe procedure, which can be done on an outpatient basis under moderate sedation. EBUS-TBNA has been shown to be a safe modality to obtain tissue for diagnosis, staging and molecular profiling in lung cancer. EBUS-TBNA stands out in comparison with other modalities for tissue acquisition in lung cancer. EBUS-TBNA performed with the patient under moderate sedation yields sufficient tissue for sequential molecular analysis in most patients. In this review, we describe the role of EBUS-TBNA in various aspects of diagnosis and staging of lung cancer in the present era along with its future aspects.

Abstract
Summary Transbronchial needle aspiration (TBNA) of the hilar and mediastinal lymph nodes and lung masses is a powerful tool in the diagnostic evaluation of mediastinal adenopathies including malignancies. As its use becomes more widespread, few cases have been reported with complications. We present a case of a 57-year-old man who was transferred to our institution for uncontrolled haemoptysis following endobronchial ultrasound-guided TBNA. At our institution, emergent bronchoscopy revealed a large clot distal to the right upper lobe bronchus without a visible fistula tract. A CT pulmonary angiogram and a subsequent pulmonary angiogram showed an aneurysm originating from the right superior pulmonary vein. Management was conservative with strict blood pressure control and lowering the left atrial pressure allowed spontaneous resolution of the bleed.
