In spite of the developments in chemo- and radiotherapy, surgery remains the mainstay of curative treatment of early stage non-small cell lung cancer (NSCLC). In stage Ia/Ib (T1, T2, N0), NSCLC lobectomy offers the best chance for cure, yielding survival rates of between 58 and 76%. Since the extent of mediastinal lymph node dissection does not seem to play a major prognostic role in stage Ia, video-thoracoscopic lobectomy yields equally good results as the open approach. Due to the necessity for a small thoracotomy when harvesting the specimen and the time-consuming lymph-node dissection minimally invasive lobar resections have failed to become routinely used. Minor resections, though sometimes necessary from the functional point of view, have a lower curative potential. They yield the best results if applied in tumors measuring less than 2 cm. Stage II, characterized by involvement of the N1-position and/or a more central tumor growth, has a 5-year survival of 45-52% and requires treatment by lobectomy or pneumonectomy. Sleeve resection may obviate the need for pneumonectomy in central upper-lobe tumors. In interlobar N1, however, pneumonectomy is indicated from the oncological point of view, since even meticulous lymph-node dissection is unable to achieve tumor control in this situation.
