The definitive diagnosis of<unk><unk>  of the lung is made by immunohistochemical staining and pathological subtyping of the specimen collected from biopsy, needle aspiration, sputum cytology or surgical resection of the tumor. Specimen for immunohistochemical analysis and pathological subtyping may be collected by transthoracic needle biopsy, bronchoscopy with biopsy, surgical resection, video-assisted thoracoscopic surgery (VATS), endoscopic ultrasound-guided fine needle aspiration (EUS-FNA), endobronchial ultrasound guided transbronchial needle aspiration (EBUS-TBNA) and rarely sputum cytology.
