What was of screen-detected stage I lung cancer in the National Lung Screening Trial (NLST), and was it affected by screening method, patient or tumor characteristics, or treatment method? The study cohort consisted of all NLST participants with screen-detected stage I lung cancer. Lung cancer-specific survival for stage I overall and for IA and IB substages were compared in the low-dose CT and chest radiography (CXR) screening randomization arms and with an analogous cohort from the Surveillance, Epidemiology, and End Results Program of the National Cancer Institute; the cumulative incidence competing risk method was used for analysis. Cox proportional hazards models were used to evaluate the association between lung cancer-specific survival and screening arm, patient factors, primary tumor size, and treatment. There were 324 screen-detected stage I lung cancers in the low-dose CT arm and 125 ter with low-dose CT imaging than with CXR screening or in the general population, for smaller primary tumor size, and with surgical treatment. The diagnosis of peripheral pulmonary lesions (PPL) continues to present clinical challenges. Despite extensive experience with guided bronchoscopy, the diagnostic yield has not improved significantly. Robotic-assisted bronchoscopic platforms have been developed potentially to improve the diagnostic yield for PPL. Presently, limited data exist that evaluate the performance of robotic systems in live human subjects. What is the safety and feasibility of robotic-assisted bronchoscopy in patients with PPLs? This was a prospective, multicenter pilot and feasibility study that used a robotic bronchoscopic system with a mother-daughter configuration in patients with PPL 1 to 5cm in size. The primary end points were successful lesion localization with the use of radial probe endobronchial ultrasound (R-E
