Results These 93 patients were referred from 12 hospitals and 20 had undergone previous undiagnostic procedures (6 EBUS, 14 bronchoscopy). The mean age was 67 years (range 27 - 87) and 50 were male. 82 were performed under local anaesthesia using lignocaine spray and intravenous midazolam (1 - 10 mg; mean 4 mgs) and the remaining 11 under general anaesthesia. 200 lymph nodes (2R, 4R, 4L, 7, 10R, 10L, 11R) and 13 lung lesions were biopsied. Results were as follows: Adequate samples were obtained in 99% (91/93) and the NSCLC - NOS rate was 2%. 31 adenocarcinoma, 10 squamous cell carcinoma, 10 small cell carcinoma, 1 NSCLC - NOS, 1 large cell neuroendocrine carcinoma, 1 soft tissue lesion (repeat EBUS showed myxoid spindle cell mesenchymal lesion), 1 breast carcinoma, 19 nonspecific benign nodes, 15 sarcoid and 2 TB. There were no complications. ...
Purpose: Anaplastic lymphoma kinase (ALK) fusion genes represent novel oncogenes for non-small cell lung cancers (NSCLC). Several ALK inhibitors have been developed, and are now being evaluated in ALK-positive NSCLC. The feasibility of detecting ALK fusion genes in samples obtained by endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) was determined. The clinicopathologic characteristics of ALK-positive lung cancer were also analyzed.. Experimental Design: From April 2008 to July 2009, NSCLC cases with hilar/mediastinal lymph node metastases detected by EBUS-TBNA were enrolled. Positive expression of ALK fusion protein was determined using immunohistochemistry, and ALK gene rearrangements were further examined to verify the translocation between ALK and partner genes using fluorescent in situ hybridization and reverse transcription-PCR. Direct sequencing of PCR products was performed to identify ALK fusion variants.. Results: One hundred and nine cases were eligible for ...
Im sorry that you are having to deal with this now. I agree with Kathy that you should join Smart Patients website where you will find more individuals with a Stage 4 diagnosis, and that have had a mediastinal lymph node issue. It is also a wonderful site with caring, educated people who want to help....just like here. Some people belong to both sites. Im concerned that you are being treated by your urologist. If I were you I would be seeing an oncologist, hopefullly a urological oncologist. I find it interesting that your doctor has sent you to a pulmonologist before sending you to an oncologist. An oncologist will look at things differently...more the whole picture. The pulmonologist is looking at your lungs. To me its like tunnel vision on a specialists part. I think it goes with the territory. They want to do what they can to help you. I am hoping that your swollen mediastinal lymph node is nothing. Its possible its nothing, and you need to keep that in mind. However, if it is possible ...

Patient J.P. (date of birth 04/01/69) was diagnosed in October 2005. A wide excision with 2-cm safety margins was carried out. The left axillary sentinel lymph node biopsy (SLNB) was negative and computed tomography (CT) showed no metastasis. Peginterferon α-2b was administered at a dose of 3 μg/kg/week s.c. from December 2005 to September 2006. In August/September 2006, suspected pulmonary and mediastinal lymph node metastases identified on a thoracic CT scan were confirmed by thoracotomy and pulmonary biopsy. From September 2006 onwards the patient received numerous courses of polychemotherapy (DTIC, cisplatin and vindesine on days 1 and 8) achieving a partial response on the CT scan. In May 2007, there was no evidence of mediastinal lymph node metastasis or residual lung metastasis by CT; PET indicated that lung metastases were inactive. In September 2007, progression of the residual lung metastasis and suspected hepatic metastases (segment 8) was noted and confirmed by excision 2 months ...

Researchers used a cost-minimization model to compare various diagnostic approaches in the evaluation of patients with NSCLC. It was less expensive to use an initial endoscopic ultrasound (EUS) with fine needle aspiration (FNA) to detect a mediastinal lymph node metastasis ($18,603 per patient), compared with combined EUS FNA and endobronchial ultrasound ...
The esophagus presents an excellent window for visualization of surrounding structures in the mediastinum. present nomenclature divides the mediastinum into three parts: the upper section (upper esophageal sphincter to aortic arch), middle (aortic arch to subcarinal region, just distal to the azy-gos vein), and lower (subcarinal region to cardia). Figure 3 demonstrates paraesophageal structures and organs. The trachea is seen only as an air column; thus its wall cannot be delineated. Lymph nodes may be visible along the length of the esophagus, even in normal individuals. They may be especially pronounced in the subcarinal region. peri-aortic tissue is seen alongside the distal esophagus.. Lymph nodes can be identified in the posterior mediastinum, retroperitoneum, and celiac regions. posterior mediastinal lymph nodes are predominantly left-sided and communicate with the para-aortic lymph nodes of the abdomen; hence thorough evaluation of the celiac region is important. Additionally, metastases ...

The mediastinum is the anatomic region medial to the pleural sacs between the sternum, vertebral column, rib 1, and the diaphragm. The mediastinum is further divided into inferior and superior parts by a horizontal plane passing through the sternal angle to the T4-T5 intervertebral disc (Figure 5-1A). The inferior mediastinum is classically subdivided into anterior, middle, and posterior parts. Therefore, the four subregions of the mediastinum are as follows: ...
Introduction: Elastography has been proposed for quantitative imaging of strain and elastic modulus distributions in soft tissues. This method generates a strain profile through external tissue compression from the ultrasound transducer.. It has been shown to increase the sensitivity and specificity of FNA for the detection of malignancy. Recently, it has become possible to perform elastographic measurements via an EBUS-bronchosope. It is unclear whether this technique is able to increase the accuracy of EBUS-FNA of mediastinal lymph nodes by a better guidance of the puncture sites. The aim of this study is to check whether elastography using the new ultrasound processor is feasible within a clinical routine and whether it could improve the accuracy of mediastinal lymph node sampling in patients with malignancies.. Method: Elastography was performed in 14 patients with 29 lymph node stations qualitatively (pattern) and quantitatively (strain ratio). All bronchoscopies were done in conscious ...

Accurate diagnosis of enlarged hilar/mediastinal lymph nodes is mandatory for adequate management of patients with known primary malignancy. We aimed to determine the sensitivity,specificity,accuracy of EBUS-TBNA for clarification of the nature of enlarged hilar/mediastinal lymph nodes in patients with known extrathoracic malignancy. Patients with extrathoracic malignancy who had undergone EBUS-TBNA for assessment of enlarged hilar/mediastinal lymph nodes in December 2008-September 2011 were reviewed. 48 patients who underwent EBUS-TBNA were included. Mean age of 12 male,36 female patients was 57.38 ±11.60. Malignancy was detected in 18(37.5 %),tuberculosis in 6(12.5%),sarcoidosis in 4(8.3%),anthracosis in 2(4.2%),reactive adenitis in 18(37.5%). EBUS-TBNA was also found to offer an effective accurate and minimally invasive strategy for evaluating nonmalignant lesions of pathological hilar and mediastinal lymph nodes such as tuberculosis and sarcoidosis. The sensitivity and specificity of ...

A mediastinoscopy is a surgical procedure performed to examine the mediastinum. The mediastinum is the space behind the sternum (breastbone) in the middle of the chest that separates the two lungs. It contains lymph nodes, the heart and its great vessels, the trachea, the esophagus, and the thymus gland.. The mediastinum can be visualized by the use of an endoscopic instrument called a mediastinoscope. A mediastinoscope is a lighted, long, thin, flexible tube that can visualize the organs and structures of the mediastinum. It also has the capacity to transmit images onto a TV-like monitor.. The procedure is performed in an operating room under general anesthesia. The surgeon makes a small incision in the neck above the top of the sternum and inserts the mediastinoscope. In addition to directly visualizing the mediastinum, tissue samples of mediastinal lymph nodes may be obtained. These lymph nodes receive lymphatic drainage from the lungs. A biopsy of these lymph nodes helps to identify disease ...

All patients with lung cancer may have mediastinal metastases. Although PET scans are quite sensitive for identifying mediastinal metastases, they remain less accurate than mediastinoscopy (see Chapter 70). Preoperative mediastinoscopy is indicated for all patients with a PET scan-positive mediastinum and should be considered for certain patients with a PET scan-negative mediastinum (i.e., those with enlarged nodes on CT scan or with hilar lesions). Although the PET scan remains useful for ruling out distant metastases, it should not be the only study performed to evaluate the mediastinum. Many patients have been denied resection because their PET scan was positive in the mediastinum, only to find a more knowledgeable physician who, on mediastinoscopy, diagnosed mediastinal granulomatous disease instead and then successfully resected the patients stage I cancer (Table 71-1). ...

We report the case of 20-year-old man with a history of Ewings sarcoma in the left humerus diagnosed at the age of 15, who has been in medical oncological follow-up since then. After the diagnosis, he received 5 cycles of neoadjuvant VAC/ifosfamide-VP-16, followed by radical surgery, resulting in pathological complete response according to pathology reports. The patient completed 12 adjuvant cycles of the same regimen and proceeded to regular monitoring. After 2 years free of disease, he received a diagnosis of probable pleuro-pulmonary relapse on a PET-CT, which showed hypermetabolic foci in the oblique fissure of the right lung and in the right subcarinal and hilar lymph nodes, although the latter were described as probably of a non-specific inflammatory nature, and close monitoring with imaging techniques was recommended. No known drug allergies. No toxic habits or occupational exposure. Student; no significant family history. He was referred by the medical oncology department to the ...
Mediastinal fat necrosis (MFN) or epipericardial fat necrosis, as it is commonly referred to in the literature, is a rare self-limiting cause of chest pain of unclear etiology. MFN affects previously healthy individuals who present with acute pleuritic chest pain. Characteristic computed tomography (CT) findings include a fat attenuation lesion with intrinsic and surrounding increased attenuation stranding. There is often associated thickening of the adjacent pericardium and/or pleural effusions. We present two cases of MFN manifesting as ovoid fat attenuation lesions demarcated by a soft tissue attenuation rim with intrinsic and surrounding soft tissue attenuation stranding and review the clinical and pathologic features of these lesions. Knowledge of the clinical presentation of patients with MFN and familiarity with the characteristic imaging findings of these lesions should allow radiologists to prospectively establish the correct diagnosis and suggest conservative management and follow-up.

The results of this systematic review suggest that the transesophageal use of the echobronchoscope is a safe and effective method of accessing the mediastinum, and provides incremental diagnostic yield over and above that achieved with EBUS-TBNA alone. Overall, we found a good incremental yield (approximately 8%) of adding EUS-B-FNA to the EBUS-TBNA procedure in the diagnosis of mediastinal lymphadenopathy. The sensitivity of the combined technique was significantly higher than EBUS-TBNA alone (91% vs 80%), in mediastinal staging of lung cancer. In fact, only 10 combined procedures need to be performed to achieve a diagnosis in one additional patient, when compared with EBUS-TBNA alone. The sensitivity of the combined technique is similar to the sensitivity (86%) reported in a meta-analysis of combined EBUS-TBNA plus EUS-FNA by Zhang et al10 However, our analysis is different from the previous meta-analysis in that we have included only those studies that have utilized the same echobronchoscope ...

This chapter aims at introducing the interested Pulmonologist/Interventional Pulmonologist to the esophageal ultrasound. In this chapter, we give short descriptions of some technical aspects of the endobronchial ultrasound (EBUS) scope and explain in detail why we believe the EBUS scope is well suited to be an esophageal scope in the hands of the trained pulmonologist. The chapter then explains indications and benefits of this procedure that we consider central to the practice of chest physicians. We also describe in steps how to reach each lymph node station using the EBUS scope as a EUS scope (EUS-B) from our own experience. Procedure-related complications and contraindications are also described.

100 years ago, lung cancer was a rare disease.1 Over time it has become one of the leading causes of cancer death worldwide.2 Along with this the diagnostic and also the therapeutic implications have changed several times over the last few decades. In 1968 the first TNM description was published, trying to standardize the tumor staging and thereby the specific therapeutic recommendations. Today the 7th edition of the TNM system is still in use and the fact that the staging of the mediastinum is one of the most important topics has still not been challenged.3. In 1964 Werner Maaßen published his first full report about mediastinoscopy as a staging technique and in the following years the technique was established as the gold standard for the mediastinum.4. Even after the implementation of improved imaging techniques like computer tomography (CT) and Positron emissions tomography (PET), the surgical option was not discussed.3.
