ABSTRACT
To determine if wedge resection is equivalent to lobectomy for Stage I Non-Small Cell Lung Cancer (NSCLC) and to evaluate the impact of radiologic and pathologic variables not available in large national databases. Records were reviewed from 2010-2016 for patients with pathologic Stage I NSCLC who underwent wedge resection or lobectomy. Propensity score matching was performed on pre-operative variables and patients with ≥1 lymph node removed. Clinical variables were compared. Kaplan-Meier curves and multivariable Cox proportional hazard models for 5-year overall survival (OS), disease-free (DFS), and locoregional-recurrence-free survival (LRFS) were created. A total of 1086 patients met inclusion criteria; 391 lobectomies and 695 wedge resections. Propensity score matching yielded 167 pairs of lobectomy and wedge resection patients. Complications were fewer for wedge resections than lobectomies, 19.2% for wedge resection patients vs 34.1% for lobectomy patients, p < 0.01. OS was equivalent between groups, 86.2% for lobectomy patients vs 83.4% for wedge resection patients p = 0.47. DFS was similar, 79.0% for lobectomy patients vs 72.5% for wedge resection patients p = 0.10. Overall LRFS was worse in wedge resection patients vs lobectomy patients, 82.0% vs 93.4% p < 0.01. However, in the matched wedge resection patients with a margin >10 mm the LRFS was equal to that of lobectomy patients, 86.4% for wedge resection patients vs 91.8% for lobectomy patients p = 0.140. Patients with Stage I NSCLC can experience similar OS, DFS, and LRFS with wedge resection as compared to lobectomy, when wedge resection margins are >10 mm and appropriate lymph node dissection is performed.
