Short- and long-term outcomes in elderly patients with locally advanced non-small-cell lung cancer treated using video-assisted thoracic surgery lobectomy

BACKGROUND: In recent years, video-assisted thoracic surgery (VATS) lobectomy has been used to treat locally advanced non-small-cell lung cancer (LA-NSCLC). However, VATS has not been reported in elderly patients (≥70 years) with LA-NSCLC. The purpose of this study was to compare short- and long-term outcomes of patients with LA-NSCLC aged ≥70 years and 55–69 years treated with VATS. PATIENTS AND METHODS: From January 2012 to January 2018, a total of 83 patients with LA-NSCLC who were ≥55 years of age underwent VATS. Patients were divided into ≥70 years group (37 cases) and 55–69 years group (46 cases), based on their age at the time of VATS. Short- and long-term outcomes of these two groups of patients were compared. RESULTS: American Society of Anesthesiologists scores of ≥70 years patients were higher than those of 55–69 years patients. No significant differences were observed when comparing the general preoperative data. For short-term outcomes, there was no significant difference between the two groups of patients in length of surgery, intraoperative blood loss, conversion to thoracotomy, postoperative 30-day complication rate and severity, postoperative 30-day mortality, pathological results, compliance with adjuvant chemotherapy, or other factors. Long-term follow-up results showed that recurrence, overall survival, and disease-free survival were similar in both groups. Furthermore, multivariate analysis showed that age was not an independent predictor of overall and disease-free survival. CONCLUSIONS: VATS in elderly patients (≥70 years) with LA-NSCLC can result in short- and long-term outcomes similar to those of 55–69 years patients with LA-NSCLC.
