摘要: Background We investigated the association between survival and number of examined lymph nodes after sublobar resection for node-negative non-small cell lung cancer with size 2 cm or less. Methods The Surveillance, Epidemiology, End Results database was used to identify patients diagnosed less from 2004 2014 underwent wedge segmentectomy. Patients were stratified by procedure (wedge resection, segmentectomy), tumors (≤1 cm, 1 cm), (0, 3, 4 9, ≥10). relationship resected overall (OS)/lung cancer-specific (LCSS) analyzed. A total 2,298 566 segmentectomy identified. Segmentectomy performed bigger (1.43 versus 1.38 cm) associated more (median number: 3 1). Multivariable analysis propensity score matching revealed that node improved undergoing while not In group, OS 9 LCSS compared without evaluated lesions No benefit observed when 10 resected. For incremental improvement in appeared increase number. More than 16 conferred no additional Conclusions should be respectively. segmentectomy, did confer benefits
