Summary
Brief summary (as posted)
Sublobar resection (SR) has been recognized as non-inferior to lobectomy for small-sized non-small cell lung cancer (NSCLC). This study aimed to systematically identify the potential factors influencing the feasibility and surgical margin quality of SR for small-sized NSCLC. Patients with small-sized NSCLC (≤2 cm) who underwent SR or lobectomy between 2020 and 2023 were screened. Surgical procedures were determined by discussion under the guidance of 3D-CTBA. A surgical margin ≥ the maximum tumor diameter was considered sufficient. SR with a sufficient surgical margin was considered eligible. Univariate and multivariate logistic regression analyses were performed to identify factors affecting the feasibility and margin quality of SR.
