Abstract
Objective Endoscopic ultrasound-guided fine-needle aspiration/biopsy (EUS-FNA/FNB) is an accurate technique for sampling the pancreas and mediastinum. The aim of this study was to determine the value of EUS-FNA/FNB in the diagnosis of mediastinal lesions. Methods Data from 107 patients who underwent EUS-FNA/FNB for mediastinal lesions were evaluated. Results The sensitivity, specificity, positive predictive value, and negative predictive value of EUS-FNA/FNB for mediastinal lesions were 92.00%, 100%, 100%, and 85%, respectively. The sensitivity, specificity, positive predictive value, and negative predictive value of EUS-FNA for malignant mediastinal lesions were 92.00%, 100%, 100%, and 86.00%, respectively. The sensitivity, specificity, positive predictive value, and negative predictive value of EUS-FNB for malignant mediastinal lesions were 92.00%, 100%, 100%, and 82.00%, respectively. Except for the discomfort caused by conventional gastroscopy, none of the patients had any complications, such as damage to surrounding large blood vessels or nerves. Conclusion EUS-FNA/FNB is an effective tool for diagnosing unknown mediastinal lesions, without any obvious complications.

Tamura T, Ashida R, Kitano M. The usefulness of endoscopic ultrasound in the diagnosis of gallbladder lesions. Front Med (Lausanne) 2022; 9:957557. [PMID: 36106323 PMCID: PMC9465250 DOI: 10.3389/fmed.2022.957557] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2022] [Accepted: 08/08/2022] [Indexed: 11/27/2022] Open
Abstract
Gallbladder tumors are neoplastic lesions; however, it can be difficult to distinguish between benign and malignant gall bladder tumors before surgery, although endoscopic ultrasound (EUS) is useful for differentiation. Fundamental B mode EUS (FB-EUS) and contrast-enhanced harmonic EUS (CH-EUS) are reported to be useful for the diagnosis of gallbladder tumor because they allow evaluation of polypoid lesion and gallbladder wall thickening. Scoring systems based on FB-EUS imaging are available for the diagnosis of malignant gallbladder polypoid lesions. The characteristic findings of malignant gallbladder polypoid lesions on CH-EUS include the presence of irregular intratumoral vessels and perfusion defects. The characteristic findings of malignant gallbladder wall thickening on FB-EUS include wall thickening >12 mm, hypoechoic internal echogenicity, inhomogeneous internal echo pattern, and disrupted wall layer, whereas CH-EUS findings include hypovascular enhancement and inhomogeneous contrast distribution pattern. In addition, FB-EUS and CH-EUS are useful for evaluating the stage of gallbladder carcinoma because they allow the evaluation of the depth of invasion of the gallbladder wall. It is usually difficult to obtain pathological evidence from gallbladder tumors before surgery and chemotherapy, even though the histological diagnosis is necessary for determining treatment policy. EUS-guided fine needle aspiration (EUS-FNA) is useful for obtaining pathological samples from gallbladder tumors before surgery and chemotherapy. The accuracy rate of EUS-FNA for gallbladder tumor is as high as 90%, but complications such as bile leakage and needle track seeding can be a problem, although it was reported that contrast-enhanced harmonic imaging is useful for avoiding them.

Abstract
BACKGROUND/PURPOSE The objectives of this study were: (1) to determine the incidence of lymphoproliferative disorders in a cohort of patients requiring a biopsy at a tertiary pediatric center; and (2) to elucidate the demographic, clinical, laboratory and diagnostic imaging characteristics associated with a malignant diagnosis. METHODS A retrospective review of pediatric cervical lymph node biopsies performed between 2012 and 2019 at a tertiary center was undertaken. Demographic data, clinical presentations, laboratory results, diagnostic imaging findings, and pathology results were compiled and analyzed to identify characteristics associated with a malignant diagnosis. RESULTS Malignancy was identified in 49.5% of patients (55/111) subjected to a cervical lymph node biopsy. The median age of patients with a benign diagnosis was lower than malignant diagnosis (11.0 vs. 14.0 years, p < 0.01). Mediastinal lymphadenopathy based on chest radiography and/or computed tomography scan was identified in 37/49 malignant cases (75.5%) CONCLUSION: In this retrospective study, 49.5% of biopsies performed at a tertiary pediatric setting yielded a malignant diagnosis. Traditional clinical characteristics such as weight loss, night sweats and nodal texture were not informative when derived retrospectively. The most valuable features identified were increased age, increased long and short axis measurements of the involved node(s), and the presence of mediastinal lymphadenopathy. LEVEL OF EVIDENCE Level III.

Abstract
Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) technology is important in the diagnosis of intrathoracic benign and malignant lymph nodes (LNs). With the development of EBUS imaging technology, its role in noninvasive diagnosis, as a supplement to pathology diagnosis, has been given increasing attention in recent years. Many studies have explored qualitative and quantitative methods for the three EBUS modes, as well as a variety of multimodal analysis methods, to find the optimal method for the noninvasive diagnosis using EBUS for LNs. Here, we review and comment on the research methods and predictive diagnostic value, discuss the existing problems, and look ahead to the future application of EBUS imaging.

Abstract
OBJECTIVE To evaluate the value of EBUS-TBNA in the diagnosis of lung and mediastinal lesions. METHODS Prospective cohort study that included 52 patients during a 2-year period (2016 to 2018) who underwent EBUS-TBNA. RESULTS Among the 52 individuals submitted to the procedure, 22 (42.31%) patients were diagnosed with locally advanced lung cancer (N2 or N3 lymph node involvement). EBUS-TBNA confirmed the diagnosis of metastases from other extrathoracic tumors in the mediastinum or lung in 5 patients (9.61%), confirmed small cell lung cancer in 3 patients (5.76%), mediastinal sarcoidosis in 1 patient (1.92%), and reactive mediastinal lymph node in 8 patients (15.38%); insufficient results were found for 3 patients (5.76%). Based on these results, EBUS-TBNA avoided further subsequent surgical procedures in 39 of 52 patients (75%). The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were 86%, 100%, 100%, 77%, and 90%, respectively. No major complications were observed. CONCLUSIONS EBUS-TBNA is a safe, effective, and valuable method. This technique can significantly reduce the rate of subsequent surgical procedures required for the diagnosis of lung and mediastinal lesions.

Abstract
BACKGROUND EBUS is being widely used today for echolocation of lymph nodes for FNAC. We present a systematic review and meta-analysis to assess the diagnostic accuracy of EBUS characteristics of lymph nodes in diagnosing malignancy. METHODS A systematic search of published literature was undertaken using databases like PubMed, Web of Science, Cochrane, Google Scholar and Researchgate. Those studies reporting any endobronchial ultrasonography features of malignant lymph nodes like size, margins, echogenicity, shape, central hilar structure (CHS), coagulation necrosis sign (CNS) or color power doppler index (CPDI) were included for review. Random effects model was used to calculate pooled sensitivity, specificity, positive and negative likelihood ratios (LR), and diagnostic odds ratio (DOR). The review protocol was registered with the International prospective register of systematic reviews (PROSPERO registration no. CRD42019117716). RESULTS 992 articles were retrieved of which 542 articles were evaluated in detail and finally 29 articles met the inclusion criteria. All EBUS features except CPDI showed a statistically significant area under the SROC curve. CNS showed highest area under the SROC curve [0.81 (SE: 0.09)] with maximum pooled specificity [0.93, 95%CI: 0.92-0.94], maximum pooled LR+ [5.12, 95%CI: 2.56-10.2] and DOR [9.23, 95%CI 3.85-22.15]. Maximum sensitivity was seen for CHS 0.91 [95%CI: 0.90-0.92]. CONCLUSION EBUS features have the potential to help in more precise location of a malignant lymph node thereby helping in increasing the diagnostic yield. However, high diagnostic accuracy of various EBUS features can currently only be said to supplement tissue diagnosis.

Abstract
Lung cancer is generally diagnosed through traditional bronchoscopy by pulmonologists, whereas data on the application of transesophageal endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) for lung cancer diagnosis in China are very rarely reported. We herein describe a case of a 62-year-old woman who presented with non-productive cough and was found to have a pulmonary mass in the upper lobe of the right lung. The results of positron emission tomography revealed an elevated level of 18F-fluorodeoxyglucose accumulation (maximum standardized uptake value of 13.6) in the left adrenal gland. Thus, EUS-FNA was performed to identify the suspected metastasis to the left adrenal gland, and the histopathological examination of the bioptic specimen demonstrated an adenocarcinoma, confirming the value of EUS-FNA as a first-line minimally invasive approach for diagnosis and staging in patients with lung cancer.

Abstract
New technologies in endoscopic ultrasound (EUS) evaluation have been developed because of the need to improve the EUS and EUS-fine needle aspiration (EUS-FNA) diagnostic rate. This paper reviews the principle, indications, main literature results, limitations and future expectations for each of the methods presented. Contrast-enhanced harmonic EUS uses a low mechanical index and highlights slow-flow vascularization. This technique is useful for differentiating solid and cystic pancreatic lesions and assessing biliary neoplasms, submucosal neoplasms and lymph nodes. It is also useful for the discrimination of pancreatic masses based on their qualitative patterns; however, the quantitative assessment needs to be improved. The detection of small solid lesions is better, and the EUS-FNA guidance needs further research. The differentiation of cystic lesions of the pancreas and the identification of the associated malignancy features represent the main indications. Elastography is used to assess tissue hardness based on the measurement of elasticity. Despite its low negative predictive value, elastography might rule out the diagnosis of malignancy for pancreatic masses. Needle confocal laser endomicroscopy offers useful information about cystic lesions of the pancreas and is still under evaluation for use with solid pancreatic lesions of lymph nodes.

Abstract
AIM: To assess the usefulness of contrast-enhanced harmonic endoscopic ultrasonography (CH-EUS) for lymph node metastasis in pancreatobiliary carcinoma.
METHODS: All patients suspected of pancreatobiliary carcinoma with visible lymph nodes after standard EUS between June, 2009 and January, 2012 were enrolled. In the primary analysis, patients with successful EUS-fine needle aspiration (FNA) were included. The lymph nodes were assessed by several standard EUS variables (short and long axis lengths, shape, edge characteristic and echogenicity), color Doppler EUS variable [central intranodal blood vessel (CIV) presence] and CH-EUS variable (heterogeneous/homogeneous enhancement patterns). The diagnostic accuracy relative to EUS-FNA was calculated. In the second analysis, N-stage diagnostic accuracy of CH-EUS was compared with EUS-FNA in patients who underwent surgical resection.
RESULTS: One hundred and nine patients (143 lymph nodes) fulfilled the criteria. The short axis cut-off ≥ 13 mm predicted malignancy with a sensitivity and specificity of 72% and 85%, respectively. These values were 72% and 63% for the long axis cut-off ≥ 20 mm, 62% and 75% for the round shape variable, 81% and 30% for the sharp edge variable, 66% and 61% for the hypoechogenicity variable, 70% and 72% for the CIV-absent variable, and 83% and 91% for the heterogeneous CH-EUS-enhancement variable, respectively. CH-EUS was more accurate than standard and color Doppler EUS, except the short axis cut-off. Notably, three patients excluded because of EUS-FNA failure were correctly N-staged by CH-EUS.
CONCLUSION: CH-EUS complements standard and color Doppler EUS and EUS-FNA for assessment of lymph node metastases.

Abstract
The objective of this study was to assess the utility of endobronchial ultrasound (EBUS) morphology of lymph nodes in predicting benign cytology of transbronchial needle aspirates in a prospective observational study. Five ultrasonic morphological characteristics of mediastinal and hilar lymph nodes were recorded: size, shape, margins, echogenic appearance and the presence of a central blood vessel. These characteristics were correlated with the final diagnosis. A total of 402 consecutive patients (237 males and 165 females) undergoing EBUS were studied. The final diagnosis was malignant disease in 244 (60.6%) and benign disease in 153 (38.05%) subjects. Out of 740 sampled nodes, in 463 (62.6%) malignant cells were identified, whereas in 270 (36.5%) nodes, no malignant cells were identified. On univariate analysis small size, triangular shape and the presence of a central vessel were predictive of a benign aetiology. In the final multivariate model, a predictive probability of 0.811 (95% CI 0.72-0.91) for benign disease was found if lymph node size was <10 mm and a central vessel was present. Sonographic appearances of lymph nodes improve the predictive probability of EBUS for benign aetiologies, and may reduce the number of nodes requiring sampling and the need for further invasive investigations.

Abstract
Ultrasound imaging has gained importance in pulmonary medicine over the last decades including conventional transcutaneous ultrasound (TUS), endoscopic ultrasound (EUS), and endobronchial ultrasound (EBUS). Mediastinal lymph node (MLN) staging affects the management of patients with both operable and inoperable lung cancer (e.g., surgery vs. combined chemoradiation therapy). Tissue sampling is often indicated for accurate nodal staging. Recent international lung cancer staging guidelines clearly state that endosonography should be the initial tissue sampling test over surgical staging. Mediastinal nodes can be sampled from the airways [endobronchial ultrasound combined with transbronchial needle aspiration (EBUS-TBNA)] or the esophagus [endoscopic ultrasound fine needle aspiration (EUS-FNA)]. EBUS and EUS have a complementary diagnostic yield and in combination virtually all MLNs can be biopsied. Additionally endosonography has an excellent yield in assessing granulomas in patients suspected of sarcoidosis. The aim of this review in two integrative parts is to discuss the current role and future perspectives of all ultrasound techniques available for the evaluation of mediastinal lymphadenopathy and mediastinal staging of lung cancer. A specific emphasis will be on learning mediastinal endosonography. Part 1 deals with an introduction into ultrasound techniques, MLN anatomy and diagnostic reach of ultrasound techniques and part 2 with the clinical work up of neoplastic and inflammatory mediastinal lymphadenopathy using ultrasound techniques and how to learn mediastinal endosonography.

Abstract
Different imaging techniques can bring different information which will contribute to the final diagnosis and further management of the patients. Even from the time of Hippocrates, palpation has been used in order to detect and characterize a body mass. The so-called virtual palpation has now become a reality due to elastography, which is a recently developed technique. Elastography has already been proving its added value as a complementary imaging method, helpful to better characterize and differentiate between benign and malignant masses. The current applications of elastography in lymph nodes (LNs) assessment by endoscopic ultrasonography will be further discussed in this paper, with a review of the literature and future perspectives.

Abstract
BACKGROUND Lymph nodes (LNs) echofeatures on endoscopic ultrasound (EUS) and concurrent fine needle aspiration (FNA) are alternatives to highly invasive approaches for etiologic diagnosis of mediastinal lymphadenopathy (MLAD). AIMS To evaluate the efficacy of LNs echofeatures and FNA via EUS to distinguish benign LNs from LNs involved by sarcoidosis, lymphoma, and metastasis in non-lung cancer patients. METHODS A retrospective review of patients who underwent EUS-FNA for MLAD was performed. Echofeatures of LNs including echogenicity, margins, shape, and LN size were recorded. Final diagnosis was made based on surgical sampling or clinical diagnosis with long-term follow-up. Only patients diagnosed as benign MLAD, sarcoidosis, lymphoma, and metastasis included. Diagnostic value of echofeatures and FNA was evaluated. RESULTS Included were 162 patients with final diagnosis of benign (68), sarcoidosis (33), lymphoma (20), and metastasis (41). The median LN along axis in the benign group [20.5 mm (6-76)] was significantly shorter than in the metastasis [28 mm (9-82)] and sarcoidosis [27 mm (17-50)] groups (p < 0.05). The median LN short axis in the benign group [11 mm (2-50)] was significantly shorter than in the metastasis [17 mm (5-44)] and lymphoma [16 mm (7-47)] groups (p < 0.05). No other echofeatures showed a discriminant value among the groups. When performing FNA, the sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of EUS-FNA were 73.7, 100, 100, 72.2, and 84.4 %, respectively. CONCLUSION Although benign MLAD tend to be smaller than other etiologies, echofeatures of LNs are not reliable etiologic diagnostic approach to MLAD. Therefore, FNA is suggested when feasible. However, due to relatively low sensitivity, LNs with benign FNA results should be subjected to further work-up if they are clinically suspicious.

Abstract
BACKGROUND AND AIMS Endoscopic ultrasound (EUS)-guided fine needle aspiration (FNA) has been becoming the standard tool for acquiring pancreatic lesion tissue. However, a single cytologic or histologic evaluation is not satisfactory for diagnosis. In this study, we evaluated the diagnostic yield of EUS-FNA for pancreatic solid masses and intra-abdominal lymph nodes using a triple approach. METHODS This study included patients undergoing evaluation for a solid pancreatic mass (n = 59) or intra-abdominal lymph nodes (n = 16) using EUS-FNA with a 22- or 25-gauge (G) needle, respectively. The specimens from each pass were analyzed by on-site cytology using Diff-Quick stain, cytology using Papanicolaou stain, and histology with immunohistochemical (IHC) staining. RESULTS A total of 75 patients (49 males; mean age; 63.7 years) were included. The median number of needle pass for diagnosis of malignancy was 2.0, and there was no technical failure. The diagnostic accuracies with on-site cytology, cytology using Papanicolaou staining, and histology were 70.7, 80.0, and 80.0 %, respectively. The diagnostic accuracy using a triple approach was significantly greater than cytology using Papanicolaou staining alone (94.7 vs. 80.0 %; p = 0.007). In patients with malignant lesions, cytology identified 12 of 71 (16.9 %) malignant lesions that were not diagnosed by histology using IHC, and histology identified six (8.5 %) malignant lesions that were not diagnosed by cytology. CONCLUSION On-site cytopathologic evaluation combined with cytologic and histologic analysis with IHC stain for one-pass specimen is considered to be able to increase the overall accuracy of EUS-FNA in pancreatic solid masses and lymph nodes.

Abstract
OBJECTIVE Endoscopic ultrasound (EUS) is established as the most accurate technique for pre-operative locoregional staging of gastroesophageal junction (GEJ) adenocarcinoma, the purpose of the present study was to evaluate the distant lymph nodes (LNs) EUS-fine-needle aspiration (FNA) impact in therapeutic decision for patients with GEJ adenocarcinoma. MATERIALS AND METHODS Retrospective study was made, with cross-sectional, non-probabilistic analysis from prospectively collected database for all GEJ adenocarcinoma staging patients referred between January 2009 and August 2012 in Paoli-Calmette Institute in Marseille-France. RESULTS A total of 154 patients with GEJ adenocarcinoma were managed in our institution, of whom 113 (73.3%) had non-distant metastatic disease at computed tomography (CT) scan and underwent EUS for initial tumor staging prior to a treatment decision. On A total of 113 patients undergoing EUS, 8 (7%) patients underwent endoscopic resection and 6 (5.3%) underwent direct surgical resection. Of the remaining 99 patients (87.6%), 24 (21.2%) distant LN EUS-FNA were made. Seventeen LN had EUS malignant features, including 9 (52.9%) that were confirmed as malignant and underwent palliative treatment with chemotherapy. Ninety (79.6%) patients were treated with pre-operative neoadjuvant therapy and were revaluated after. 4 (4.4%) had metastatic disease at CT scan (underwent palliative treatment) and 65 (72.2%) underwent EUS restaging to treatment decision revaluation. Of these, twelve (18.4%) distant LN EUS-FNA were performed. Seven had LN EUS malignancy features, including 4 (57.1%) that were confirmed as malignant and underwent palliative treatment. The remaining 61 patients underwent surgery. As stated above, 21 patients (23.3%) did not undergo EUS restaging, including 10 (47.6%) that did not go to surgery because patient's age, poor general status and comorbidities, 6 (28.5%) had a loss of follow-up, 1 (4.7%) underwent to surgery due to chemotherapy collateral effects, 3 (14.2%) were still on pre-operative chemotherapy and 1 (4.7%) died for sepsis after mediastinal EUS-FNA, this was the only complication event evidenced. EUS-FNA changed clinical management in 54.2% of patients who met the criteria inclusion (distant LN with malignancies EUS features), which corresponds to 11.5% of patients with GEJ adenocarcinoma. CONCLUSION EUS-FNA was able to provide a different tumor staging and these differences were associated with treatment received. EUS-FNA had a significant impact on treatment decision.

Abstract
OBJECTIVE To evaluate the utility of different ultrasonographic (US) features in differentiating benign and malignant lymph node (LN) by endobronchial ultrasound (EBUS) and validate a score for real-time clinical application. METHODS 208 mediastinal LN acquired from 141 patients were analyzed. Six different US criteria were evaluated (short axis ≥10 mm, shape, margin, echogenicity, and central hilar structure [CHS], and presence of hyperechoic density) by two observers independently. A simplified score was generated where the presence of margin distinction, round shape and short axis ≥10 mm were scored as 1 and heterogeneous echogenicity and absence of CHS were scored as 1.5. The score was evaluated prospectively for real-time clinical application in 65 LN during EBUS procedure in 39 patients undertaken by two experienced operators. These criteria were correlated with the histopathological results and the sensitivity, specificity, positive and negative predictive values (PPV and NPV) were calculated. RESULTS Both heterogenicity and absence of CHS had the highest sensitivity and NPV (≥90%) for predicting LN malignancy with acceptable inter-observer agreement (92% and 87% respectively). On real-time application, the sensitivity and specificity of the score >5 were 78% and 86% respectively; only the absence of CHS, round shape and size of LN were significantly associated with malignant LN. CONCLUSIONS Combination of different US criteria can be useful for prediction of mediastinal LN malignancy and valid for real-time clinical application.

Abstract
BACKGROUND Despite an increasing number of procedures being performed, there is no consensus on an optimal approach to EUS-guided FNA (EUS-FNA) or interventions. OBJECTIVE Validate an algorithmic approach to EUS-FNA/interventions with the objective of improving technical outcomes and resource use. DESIGN Prospective study. SETTING Tertiary-care referral center. PATIENTS Consecutive patients undergoing EUS-FNA and/or interventions. INTERVENTION Phase I was a retrospective analysis of EUS-FNA/interventions performed in 548 patients. The 19-gauge needle was used for interventions, and the 22- or 25-gauge needle was used interchangeably for performing FNAs. At phase I, the technical failure rate was 11.5%. Based on these observations, an algorithm was proposed by which all transduodenal FNAs were performed by using a 25-gauge needle and other FNAs with a 22-gauge needle. All transduodenal interventions were performed with a Flexible 19-gauge needle and others with a standard 19-gauge needle. This algorithm was tested prospectively in phase II on 500 patients. MAIN OUTCOME MEASUREMENTS Compare technical failure, diagnostic adequacy, procedural complications, and average needle costs between both phases. RESULTS The technical failure rate was significantly less in phase II compared with that of phase I (1.6% vs 11.5%; P < .001) for both FNA (1.8% vs 10.9%; P < .001) and therapeutic interventions (0% vs 16.4%; P = .001). Although there was no difference in diagnostic adequacy (97.1% vs 98.4%; P = .191) or complications (0.4% vs 0.2%; P = 1.0) between phases I and II, the average cost per case was significantly less in phase II ($199.59 vs $188.30; P = .008). LIMITATIONS Single-center study. CONCLUSION An algorithmic approach to EUS-FNA/interventions yielded better technical outcomes and cost savings without compromising diagnostic adequacy.

Abstract
BACKGROUND AND OBJECTIVE Endobronchial ultrasound (EBUS) is now widely used in patients with resectable non-small-cell lung cancer to sample mediastinal lymph nodes (LN) for preoperative staging. The aim of this study was to investigate prospectively the utility of six ultrasound criteria to predict malignancy in mediastinal LN. METHODS EBUS was performed in patients with mediastinal lymphadenopathy irrespective of the underlying disease. The following criteria were expected to predict malignancy: short axis >1 cm, heterogeneous pattern, round shape, distinct margin, absence of a central hilar structure and high blood flow in a LN. A sum score prediction model for malignancy was built. If more than two criteria were present, LN was classified as high risk for malignancy. Moreover, interrater variability of two blinded investigators was evaluated. RESULTS Two hundred eighty-one LN in 145 patients were analysed. Forty-four percent of LN were found malignant, 10% revealed sarcoidosis, and 10% revealed tuberculosis. Interobserver agreement was very good. Positive predictive value was best for heterogeneity (73%), with a negative predictive value of more than 80%. The sum score resulted in an odds ratio of 15.5 if more than two criteria were positive (P < 0.00001). CONCLUSIONS The assessment of ultrasound criteria during routine EBUS examinations is feasible and reproducible with very good interrater agreement. If less than three of the described criteria are present, a LN has a very low chance of being malignant. The best single criterion to predict malignancy is heterogeneity. The introduction of the sum score of ultrasound criteria could potentially increase diagnostic accuracy.

Abstract
BACKGROUND AND OBJECTIVE Excision and histological assessment of the first draining node (sentinel lymph node) is a frequently used method to assess metastatic lymph node involvement related to cutaneous melanoma. Due to the time required for accurate histological assessment, nodal status is not immediately available to the surgeon. Hence, in case histological examination shows metastases, the patient has to be recalled to perform additional lymphadenectomy. To overcome these drawbacks we studied the applicability of photoacoustic tomographic imaging as an intra-operative modality for examining the status of resected lymph nodes. MATERIALS AND METHODS In melanoma patients undergoing lymphadectomy for metastatic disease, six suspect lymph nodes were photoacoustically (PA) imaged using multiple wavelengths. Histopathologal examination showed three nodes without tumor cells (benign nodes) and three nodes with melanoma cells (malignant nodes). PA images were compared with histology and anatomical features were analyzed. In addition, PA spectral analysis was performed on areas of increased signal intensity. RESULTS After correlation with histopathology, multiple areas containing melanoma cells could be identified in the PA images due to their increased response. Malignant nodes showed a higher PA response and responded differently to an increase in excitation wavelength than benign nodes. In addition, differences in anatomical features between the two groups were detected. CONCLUSIONS Photoacoustic detection of melanoma metastases based on their melanin content proves to be possible in resected human lymph nodes. The amount of PA signal and several specific anatomical features seem to provide additional characteristics for nodal analysis. However, it is as yet preliminary to designate a highly accurate parameter to distinguish between malignant and benign nodes. We expect to improve the specificity of the technique with a future implementation of an adjusted illumination scheme and depth correction for photon fluence.

Abstract
Mediastinal lymphadenopathy may be detected by CT-scan or positron emission tomography. Malignant (e.g, lung cancer, metastatic cancer, lymphoma), infectious (e.g, tuberculosis, histoplasmosis), and systemic processes (e.g, sarcoidosis) can cause mediastinal adenopathy. In the posterior and inferior mediastinum, endoscopic ultrasound visualizes and directs transesophageal fine needle aspiration of adenopathy. In the anterior mediastinum, endobronchial ultrasound visualizes and directs transbronchial fine needle aspiration of adenopathy. We discuss the role of EUS and EBUS in the evaluation of mediastinal adenopathy according to their anatomical localization.

Abstract
This article reviews different techniques available for diagnosis and staging of patients with non-small cell lung cancer (NSCLC). The advantages and disadvantages of each staging method are highlighted. The role of the gastroenterologist in NSCLC staging is explored. A new algorithm is proposed for the staging of NSCLC that incorporates endoscopic and endobronchial ultrasonography for mediastinal staging in patients with intrathoracic disease.

Abstract
The main purpose of staging in non-small cell lung cancer (NSCLC) is to assess mediastinal lymph node involvement, with thoracic CT being the main non-invasive test for this. However, given that up to 15% of patients who show no mediastinal lymph node involvement in the CT have lymph node metastasis during surgery, other examinations are required. Endoscopic ultrasonography guided fine-needle aspiration (EUS-FNA) has shown to be able to detect advanced disease (metastatic mediastinal lymph nodes, adrenal metastasis, mediastinal invasion by the tumour) in approximately 25% of patients with a CT that suggested a non-advanced disease. Another situation in which CT has a very limited value is in the evaluation of the response to induction therapy, with its most limiting factor being its intrinsic inability to distinguish between a tumour and necrosis. In this context, EUS-FNA has shown to have a good performance, with a sensitivity, negative predictive value and precision of 75%, 67% and 83%, respectively. In conclusion, EUS-FNA may be considered a good alternative in the pre-operative staging of patients with NSCLC, with and without diseased mediastinal lymph nodes in CT, and could play an important role in the mediastinal re-staging of these patients by identifying a patient sub-group who might benefit from additional surgical treatment.
