Abstract
BACKGROUND: The application of video-assisted thoracoscopic surgery (VATS) for complex carina surgeries in treating non-small cell lung cancer (NSCLC) patients with involved carina is controversial. This study compared short- and medium-term outcomes of VATS versus thoracotomy for carinal lung resection with carina reconstruction in treating locally advanced NSCLC, aiming to assess the potential benefit of VATS over thoracotomy for these patients. METHODS: A total of 37 consecutive NSCLC cases receiving VATS (n = 14) or thoracotomy (n = 23) for carinal lung resection with carina reconstruction from 2016 to 2021 were retrospectively identified. Baseline clinicopathological characteristics, perioperative outcomes, and survival profiles were investigated. RESULTS: Patients in the VATS and thoracotomy groups had comparable baseline clinicopathological characteristics (all p > 0.050). VATS decreased postoperative drainage volume compared with thoracotomy (1280 [1170-1510] vs. 1795 [1510-1905] mL, p = 0.012). Regarding surgical-related pains, VATS reduced numeric rating scale scores on the postoperative day 1 (4 [3, 4] vs. 5 [4, 5], p = 0.021) and day 2 (3 [3, 4] vs. 5 [3-5], p = 0.023) than thoracotomy. No difference was found between the VATS and thoracotomy groups in other perioperative outcomes, postoperative complications, and assessment of lymph nodes (LNs) and LN stations (all p > 0.050). Moreover, patients in the two groups had comparable 3-year disease-free survival (DFS), overall survival (OS), and recurrence and mortality patterns. Further subgroup and Cox hazards regression analyses also observed no difference in DFS or OS between the two groups. CONCLUSIONS: VATS reduced postoperative drainage volume and ameliorated surgical-related pain, and achieved comparable medium-term survival compared to thoracotomy for carinal lung resection with carina reconstruction in treating locally advanced NSCLC.
