Older age is not a negative factor for video-assisted thoracoscopic lobectomy for pathological stage I non-small cell lung cancer: a single-center, retrospective, propensity score-matching study.

Purpose: Video-assisted thoracoscopic surgery (VATS) has changed the surgical approach to non-small cell lung cancer (NSCLC) dramatically. The current study compares the outcomes of older and younger patients who underwent VATS lobectomy for NSCLC.

Methods: In total, 424 eligible patients with pathological stage I NSCLC underwent VATS lobectomy between 2007 and 2017. Patients were classified into two groups (< 75 and ≥ 75 years old), after which propensity score-matching was performed.

Results: After matching, 143 patients were identified. No significant difference in postoperative complication rates was observed; however, the ≥ 75-year-old group had a longer postoperative hospital stay (p = 0.001). The 5-year overall survival, relapse-free survival, and lung cancer-specific survival rates of the < 75- and ≥ 75-year-old groups were 87.1% vs. 85.6% (p = 0.537), 82.1% vs. 79.0% (p = 0.531), and 93.5% vs. 92.7% (p = 0.832), respectively.

Conclusion: Despite the longer postoperative recovery following VATS lobectomy, the short- and long-term outcomes of older patients did not differ from those of younger patients. Thus, for early-stage NSCLC, older age alone was not a negative factor for lobectomy performed via minimally invasive surgery. Naturally, the systemic condition of this population must be evaluated carefully before surgery.
