title: Multidisciplinary approach in stage III non-small-cell lung cancer: standard of care and open questions.
abstract: Lung cancer is the most frequent cause of cancer death worldwide and its global incidence has been steadily increasing during recent decades. A third of patients with newly diagnosed non-small-cell lung cancer (NSCLC) present with locally advanced disease. There is not a single widely accepted standard of care for these patients because of the wide spectrum of presentation of the disease. Although feasible and safe in experienced hands, evidence that surgical resection after induction treatment improves overall survival (OS) is lacking. For resectable or potentially resectable stage III, the findings of two phase III trials suggest that surgical resection should not be considered a standard of care but rather reserved for selected patients after critical multidisciplinary assessment, in whom surgery improves survival after downstaging if pneumonectomy can be avoided or in some T4N0-1 resectable tumours. For unresectable stage III NSCLC the standard of care is a combination of chemotherapy and radiotherapy. In those patients with good performance status and minimal weight loss, the concurrent approach has resulted in a statistically significant improvement in OS rates compared with a sequential approach in randomised clinical trials, although several questions remain unresolved.
