[Efficacy of postoperative adjuvant therapy for resected non-small cell lung cancer--an evidence-based review].

Efficacy of postoperative adjuvant therapy for non-small cell lung cancer (NSCLC) was examined based on recent evidence. In 2003, when a clinical guideline for lung cancer had been published, the efficacy of postoperative adjuvant therapy had not been established. However, results of randomized controlled studies and metaanalysis on the efficacy of postoperative chemotherapy, platinum-based chemotherapy or UFT, were presented at the annual meetings of the American Society of Clinical Oncology (ASCO) held in 2003-2005. Thus, postoperative adjuvant chemotherapy for completely resected NSCLC cases is now a standard care of therapy.
