Therapy of localized non-small cell lung cancer (take home messages).

Surgery remains the mainstay in curative therapy of stage I and II NSCLC and selected patients with stage III disease. The high rate of distant metastases occurring in patients after complete surgical resection demonstrates the need for effective adjuvant systemic therapy. However, outside of trials, (neo)adjuvant chemotherapy is currently not considered as an established standard in localized NSCLC. Postoperative radiotherapy increases local tumor control in completely resected N2 disease and after R1/R2 resections and is generally recommended in these situations. In inoperable patients radiotherapy offers the only chance of cure. Combined radiochemotherapy and the highly accelerated CHART radiotherapy have been shown to be superior to standard radiotherapy. Progress in the treatment of localized NSCLC over the last decades has been only modest and with the exception of favourable subgroups, prognosis of NSCLC remains grim. In the light of the high rate of local and distant metastases multidisciplinary approaches appear necessary in the vast majority of patients.
