Ultrasound-Guided Needle Biopsy of Neck Lymph Nodes in Patients With Suspected Lung Cancer Are the Specimens Sufficient for Complete Pathologic Evaluation to Guide Patient Management?

摘要

Background: The purpose of this study is to determine the ability of ultrasound guided needle biopsy of a neck lymph node to provide adequate tissue for complete pathologic evaluation of suspected metastatic lung cancer, including molecular testing for epidermal growth factor receptor gene mutations by pyrosequencing and anaplastic lymphoma kinase gene rearrangement by fluorescence in situ hybridization.
