Endobronchial Ultrasound- Transbronchial Needle Aspiration (EBUS-TBNA) Versus Mediastinoscopy for Mediastinal Lymph Node Staging of Non-small Cell Lung Cancer (NSCLC)

2014-07-23 21:09:56 | BioPortfolio

Summary

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.

Medical and Biotech [MESH] Definitions

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.
