For this group of patients, brain metastases are one of the major sites of tumor failure. Radical therapy of symptomatic brain metastases is seldom possible and only very rarely, long term survival can be achieved. PCI has shown to reduce the incidence of brain metastases in patients with non-small cell lung cancer to the same extent as in limited disease small-cell lung cancer. However, the exact value of PCI in stage III NSCLC patient, treated with contemporary chemo-radiation schedule with or without surgery, remains unsettled. Therefore this study is launched, in order to investigate whether PCI should become the standard of care in patients with stage III NSCLC who are treated with curative intention.
