Accurate staging of the mediastinum is essential to evaluate prognosis in non-small cell lung cancer and to devise an appropriate treatment plan. Mediastinal staging by surgical techniques (mainly cervical mediastinoscopy) is considered to be the gold standard, although surgical staging is invasive, requires general anesthesia, and is subject to potential serious complications. Endobronchial ultrasound (EBUS)-transbronchial needle aspiration (TBNA) is a new modality for the evaluation of mediastinal and hilar lymph node metastasis from lung cancer. Compared to other diagnostic methods, EBUS-TBNA is a real-time procedure that enables multiple biopsies with high-quality histologic cores under local anesthesia. However, there have been few data on the head-to-head comparisons of mediastinoscopy and EBUS-TBNA. The aim of this prospective study is to determine the sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of EBUS-TBNA and mediastinoscopy in identifying N2 and N3 lymph node for patients with non-small cell lung cancer.

The aim of this prospective study is to determine the staging accuracy of endobronchial ultrasound guided fine needle aspiration biopsy of mediastinal lymph nodes compared to the 'gold sta...
Proper staging of Lung cancer is of paramount concern when determining a treatment regime. Currently the assessment of surgical candidacy is performed with the staging process, mainly the ...
In the UK, staging of lung cancer is time consuming (taking on average more than 3 weeks), costly and inaccurate in up to 20% of cases. The investigators wish to determine whether using th...
Enlarged glands in the chest (mediastinal lymphadenopathy) is a common problem and may have a variety of different causes. In the past an operation (mediastinoscopy) was required to diagno...
Objectives: This study is designed to evaluate the added utility of endobronchial ultrasound transbronchial needle aspiration (EBUS -TBNA) over PET and CT (or PET/CT) for detecting ...
BACKGROUND Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) and guide sheath (EBUS-GS) are gaining popularity for diagnosis and staging of lung cancer compared to CT-guided...
To evaluate the accuracy of systematic mediastinal staging by endobronchial ultrasound transbronchial needle aspiration (EBUS-TBNA) (sampling of all visible nodes measuring ≥5mm from stations N3 to ...
Endobronchial ultrasound (EBUS) has revolutionized the diagnosis of lung cancer over the last decade. This minimally invasive diagnostic method has also become increasingly important in the case of ot...
Endobronchial ultrasound-guided transbronchial needle biopsy (EBUS-TBNA) has proven to be an effective and minimally invasive tool to diagnose and stage lung cancer. However, its use for the diagnosis...
Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is usually performed under moderate sedation through the oral approach. Oral insertion is performed owing to the larger siz...
Malignant neoplasm arising from the epithelium of the BRONCHI. It represents a large group of epithelial lung malignancies which can be divided into two clinical groups: SMALL CELL LUNG CANCER and NON-SMALL-CELL LUNG CARCINOMA.
A form of highly malignant lung cancer that is composed of small ovoid cells (SMALL CELL CARCINOMA).
A heterogeneous aggregate of at least three distinct histological types of lung cancer, including SQUAMOUS CELL CARCINOMA; ADENOCARCINOMA; and LARGE CELL CARCINOMA. They are dealt with collectively because of their shared treatment strategy.
An anaplastic, highly malignant, and usually bronchogenic carcinoma composed of small ovoid cells with scanty neoplasm. It is characterized by a dominant, deeply basophilic nucleus, and absent or indistinct nucleoli. (From Stedman, 25th ed; Holland et al., Cancer Medicine, 3d ed, p1286-7)
A carcinoma discovered by Dr. Margaret R. Lewis of the Wistar Institute in 1951. This tumor originated spontaneously as a carcinoma of the lung of a C57BL mouse. The tumor does not appear to be grossly hemorrhagic and the majority of the tumor tissue is a semifirm homogeneous mass. (From Cancer Chemother Rep 2 1972 Nov;(3)1:325) It is also called 3LL and LLC and is used as a transplantable malignancy.
Lung cancer is the uncontrolled cell growth in tissues of the lung. Originating in the lungs, this growth may invade adjacent tissues and infiltrate beyond the lungs. Lung cancer, the most common cause of cancer-related death in men and women, is respons...
