No.	Bronchoscopic intervention	Anesthesia time / Procedure time, min^a	Additional treatment	Baseline FEV₁ and FVC, L (% predicted value)	Post-procedural FEV₁ and FVC, L (% predicted value)	Follow-up duration (month) and final patient status
#1	Debulking, laser	31 / 23	No	2.41 (55) / 3.91 (73)	4.04 (93) / 4.96 (93)	42.5 / Under follow-up
#2	Debulking, laser	43 / 23	Surgical resection^b	2.22 (88) / 2.75 (80)	NA	42.5 / Under follow-up
#3	Debulking, laser	42 / 16	No, suspect recurrence^c	1.75 (71) / 2.29 (64)	2.82 (112) / 3.07 (85)	2.8 / Lost to follow-up
#4	Debulking, laser	30 / 15	No	3.47 (87) / 4.25 (86)	3.59 (89) / 4.30 (87)	5.6 / Under follow-up

FEV₁ = forced expiratory volume in one second, FVC = forced vital capacity, NA = not available
^a Anesthesia time refers to the time from the start of general anesthesia to awakening from general anesthesia. Procedure time refers to the time from rigid bronchoscopic intubation to extubation
^b He underwent left lower lobectomy via video-assisted thoracoscopy surgery (VATS) seven months after rigid bronchoscopy. There was residual tumor tissue with a clear surgical margin in the surgical specimen
^c Suspect recurrence because of the presence of a small nodule at the proximal left main bronchus on surveillance computed tomography at three months post-rigid bronchoscopy. No confirmational biopsy was performed on this patient, however, because he was lost to follow-up
