Improved staging using intraoperative ultrasound for mediastinal lymphadenectomy in non-small lung cancer surgery

摘要

Background: Extent of lymph node involvement in patients with non-small cell lung cancer (NSCLC) is the cornerstone of staging and influences both multimodality treatment and final outcome. The aim of this study was to investigate accuracy and characteristics of intraoperative ultrasound guided systematic mediastinal nodal dissection in patients with resected NSCLC.
