Pros: Should a patient with stage IA non-small cell lung cancer undergo invasive mediastinal staging?

Carme Obiols, Sergi Call

Abstract

Mediastinal lymph node involvement is an important prognostic factor in patients with non-small cell lung cancer (NSCLC). The American and European guidelines for preoperative mediastinal lymph node staging agree in which situations a pre-surgical exploration of the mediastinum is required in order to avoid futile pulmonary resections (1,2). Invasive mediastinal staging with cyto-histological confirmation is indicated when computed tomography (CT) shows enlarged mediastinal or hilar lymph nodes, when positron emission tomography (PET) shows an increase uptake in the mediastinum or hilum, when the tumour is centrally located and when the tumour size is more than 3 cm, especially in adenocarcinoma with high 18F-Fluorodeoxyglucose (FDG) uptake.
