Comparison of Thoracoscopic Segmentectomy and Thoracoscopic Lobectomy for Small-Sized Stage IA Lung Cancer

Thoracoscopic segmentectomy is a safe option and provides comparable oncologic results to thoracoscopic lobectomy for small (≤2 cm) peripheral stage IA non-small cell lung cancer. Tumor size is an independent prognostic factor of disease-free survival for stage IA patients with small-sized lesions.
