Data are presented as mean±sd. EBUS: endobronchial ultrasound; TBNA: transbronchial needle aspiration; PET: positron emission tomography; PTV: planning target volume; D95%: treatment volume receiving >95% of planned dose; NTCP: normal tissue complication probability. ^#: EBUS-positive/PET-negative, n=4, dose was changed; ^¶: EBUS-negative/PET-positive, n=4 (because two out of six patients where EBUS identified a lesser extent of lymph node disease could not reasonably be encompassed within a radical radiotherapy field when planned based on PET alone and therefore plans were not created), potential change in dose.
