Purpose:
To determine the survival following segmentectomy versus lobectomy in elderly patients with early-stage non-small cell lung cancer (NSCLC).
Methods:
We identified 12324 elderly (≥ 70 years) patients with stage I ≤ 3 cm NSCLC in the Surveillance, Epidemiology and End Results (SEER) database. Propensity score methods were used to balance baseline characteristics of patients undergoing segmentectomy or lobectomy. Overall survival (OS) and lung cancer-specific survival (LCSS) of patients treated with segmentectomy versus lobectomy were compared in Cox regression models after adjusting, stratifying or matching patients based on propensity scores.
Results:
Cox models adjusting, stratifying or matching propensity scores all showed that patients treated with segmentectomy had significantly worse OS and LCSS compared to lobectomy. Subgroup analysis of patients with tumors ≤ 2cm, aged ≥ 75 years, or had ≥ 7 lymph nodes examined also revealed survival advantage associated with lobectomy.
Conclusion:
Elder age alone could not justify the application of segmentectomy in early-stage lung cancer. Prospective randomized trials are warranted to validate our results.
