Objective To evaluate the clinical efficacy and complications of cryoablation for T1N0M0 non-small cell lung cancer (NSCLC).Methods  The clinical data of 38 patients with T1N0M0 NSCLC who underwent CT guided percutaneous cryoablation between October 2019 and March 2021 was retrospectively analyzed. The study outcomes included technical success, the local control rate, 1-year and 2-year progression free survival rate and complications.Results  All patients obtained satisfactory iceball coverage and the rate of technical success was 100%. The median follow-up was 14.9 (6.3 - 25.5) months. During the follow-up, 11 patients achieved completed remission, four cases suffered local progression, the local control rate was 89.5%. 1-year progression free survival rate was 96.7%, and 2-year progression free survival rate was 87.9%. The comparison of progression free survival between the T1a-b and T1c was conducted, but no significant difference was detected (P=0.35). There was no death happened during follow-up. The intraoperative complications were pneumothorax and alveolar hemorrhage, and the postoperative complications were exacerbation of cough and pneumothorax. All complications were mild and controllable.Conclusion  CT-guided percutaneous cryoablation is clinically feasible, effective and safe therapeutic method for inoperable T1N0M0 NSCLC.
