    Abstract:
    PURPOSE: Sublobar resection has been increasingly adopted in elderly patients with stage IA non-small cell lung cancer (NSCLC), but the equivalency of sublobar resection versus lobectomy among young patients with stage IA NSCLC is unknown. METHODS: Using the Surveillance, Epidemiology, and End Results (SEER) registry, we identified patients aged ≤35 years who were diagnosed between 2004 and 2013 with pathological stage IA NSCLC and treated with sublobar resection or lobectomy. We used propensity-score matching to minimize the effect of potential confounders that existed in the baseline characteristics of patients in different treatment groups. The overall survival (OS) and lung cancer-specific survival (LCSS) rates of patients who underwent sublobar resection or lobectomy were compared in stratification analysis. RESULTS: Overall, we identified 188 patients who had stage IA disease, 32 (17%) of whom underwent sublobar resection. We did not identify any difference in OS/LCSS between patients who received sublobar resection versus lobectomy before (log-rank p = 0.6354) or after (log-rank p = 0.5305) adjusting for propensity scores. Similarly, we still could not recognize different OS/LCSS rates among stratified T stage groups or stratified lymph node-removed groups before or after adjusting for propensity scores. CONCLUSIONS: Sublobar resection is not inferior to lobectomy for young patients with stage IA NSCLC. Considering sublobar resection better preserves lung function and has reduced overall morbidity, sublobar resection may be preferable for the treatment of young patients with stage IA NSCLC.
