Towards complete endoscopic staging of the mediastinum?

Introduction

Accurate staging of the mediastinum is a critical part of the management for newly diagnosed cases of lung cancer. It is well recognised in non small cell lung cancer (NSCLC) that stage at presentation is the main determinant of survival. Furthermore, the degree of spread will determine the most appropriate and optimal treatment strategy. NSCLC usually metastasises initially via the lymphatic system to locoregional lymph nodes (hilar and mediastinal) and subsequently to distant organs by haematogenous spread.
