[Indications for surgery in non-small cell lung cancer with lymph node invasion]

Abstract

Surgery is indicated for N1 non-small cell lung cancer and performed, with good results in some patients, when N2 disease is not diagnosed preoperatively "minimal N2". Following the publication of the "EORTC 08941" and "Intergroup 0139" trials, it remains debatable for patients with proven N2 disease. Good prognostic factors before treatment or post-induction favour surgery, which seems superior to radiochemotherapy if the operative risk is low (lobectomies, and some pneumonectomies). N3 status is a contraindication to surgery, except in some rare cases with a strong response to induction treatment.
