All patients will undergo CT and PET/CT. The patients without dissemination of cancer will be randomized into the EBUS/EUS and the TEMLA arms. All patients with mediastinal metastasis discovered during staging will be referred to oncological treatment. Patients without mediastinal involvement will be treated with radical surgical treatment (lobectomy or pneumonectomy with lymphadenectomy) with open or video-assisted (VATS) technique. The patients undergoing sublobar resection will be excluded from this study.
