Even with improvements in preoperative staging, surgical techniques, neoadjuvant/adjuvant options and postoperative care, there are still great difficulties in significantly improving survival, especially in locally advanced disease while early tumor stages theoretically represent the most consistent possibility of modifying the outcome of non-small cell lung cancer
