Patients undergoing EBUS-TBNA for clinical reasons as deemed necessary by the managing physician or multidisciplinary team will be randomised to undergo either EBUS-TBNA or Flex 19G EBUS-TBNA. The procedure will be performed under local anaesthesia using conscious sedation or general anaesthesia according to usual practice at the trial centre. Specimens will be placed in saline and formalin and forwarded to the pathology laboratory. The specimens will be spun down to create a cell pellet which will undergo cytological and histological examination as per usual protocol at the trial centre.The pathologist, who will be blinded as to which technique was used to obtain the sample, will grade the quality, quantity, and cellularity of the specimens.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n1.
