[Postoperative adjuvant treatment for non-small cell lung cancer].

The subjects in this study were patients who received postoperative adjuvant treatment for non-small cell lung cancer, had pathological stages I through IIIA, and underwent complete resection of their tumors. Many phase III trials with chemotherapy, radiotherapy, chemoradiotherapy or other modalities as postoperative adjuvant treatment have been conducted. However, no adjuvant treatment has been established as a result of those trials.
