NSCLC, non-small cell lung cancer; 5-YSR, 5-year survival rate; Seg., segmentectomy; MST, median survival time; N/R, not reported; DFS, disease-free survival. *, Extended segmentectomy is defined as resection of both the affected segment and adjacent subsegments plus the exploration of mediastinal and hilar lymph nodes by intraoperative frozen sectioning.
