Mediastinal Staging for Lung Cancer.

Abstract

Mediastinal lymph node staging in the setting of known or suspected lung cancer is supported by multiple professional societies as standard for high-quality care, yet proper mediastinal staging often is lacking. Neglecting pathologic lymph node sampling can understage or overstage the patient and lead to inappropriate treatment. Although some cases of nodal disease are radiographically obvious, others are not as apparent, and both situations require pathologic proof to allow for appropriate treatment selection. This article discusses the nuances of mediastinal staging and emphasizes the usefulness of a multidisciplinary approach and dialog to address lung cancer staging and treatment. We summarize the relevant guidelines and literature and provide a case scenario to illustrate the approach to mediastinal staging from our viewpoints as a thoracic surgeon and pulmonologist.
