- Patients with early-stage NSCLC who underwent sublobar resection and had ≥1 lymph node examined (LNE) had better OS and disease-specific survival than those who had no LNEs.
- Sublobar resection with anatomic segmentectomy yielded more lymph nodes for examination than wedge resection.
Why this matters
- Even though increased lymph node examination confers a survival advantage, 49.5% of wedge resection patients and 23.5% of segmentectomy patients had no lymph node examination.
- 3916 patients with early-stage NSCLC from the Surveillance, Epidemiology, and End Results database who underwent sublobar resection were analyzed.
- Funding: None disclosed.
- 18.5% underwent segmentectomy and 81.7% underwent wedge resection.
- Only 50.5% of patients who had a wedge resection and 76.5% of patients who had a segmentectomy had at least 1 LNE at pathology.
- Having ≥1 LNE was associated with better OS (OR, 0.66; P<.001 and disease-specific survival p>
- After multivariable analysis, there were no differences in OS or disease-specific survival in patients who had ≥1 LNE, regardless of surgical approach.
- Retrospective study.
