Among various ablation techniques, cryoablation has been demonstrated to be therapeutic efficacy with several advantages, including high safety, clear ablation borders, and minimal local pain. With the development of navigational bronchoscopy, pilot study on transbronchial cryoablation for peripheral lung cancer has proved its efficacy and safety, but there is a lack of prospective randomized controlled trials to verify its near-term as well as long-term efficacy and safety. This study was designed as a prospective, randomized controlled, multicenter clinical trial. A total of 110 participants will be randomly assigned to either the transbronchial group or the transthoracic group in a 1:1 ratio. The primary endpoint is the complete ablation rate at 12 months post-ablation.
