Objective: Central-type Non-small Cell Lung Cancer (NSCLC) treatment involves different surgical techniques, including Video-Assisted Thoracoscopic Surgery (VATS) and Open Thoracotomy Sleeve Lobectomy. However, there remains a lack of consensus on the most effective treatment modality.
Methods: This study strictly adhered to PRISMA guidelines. Four electronic databases were searched without time or language limitation, and studies comparing VATS and Open Thoracotomy in patients with central-type NSCLC undergoing sleeve lobectomy were included. Primary outcomes were perioperative outcomes (blood loss, operation time, intraoperative lymph node dissection count, postoperative hospital stay, and complication rates), 3-year Progression-Free Survival (PFS) rate, and Overall Survival (OS) rate.
Results: The meta-analysis included six studies with 569 patients. VATS was associated with longer operation time [SMD = 0.75, 95% CI (0.29, 1.21)], less intraoperative blood loss [SMD = -0.23; 95% CI (-0.44, -0.01)], and shorter hospital stay [SMD = -0.53; 95% CI (-0.73, -0.34)]. There were no significant differences in the number of lymph nodes dissected, postoperative complications, and 3-year PFS and OS rates between the two groups.
Conclusions: VATS sleeve lobectomy for central-type NSCLC results in less surgical trauma and quicker postoperative recovery without adversely impacting tumor prognosis compared to open thoracotomy sleeve lobectomy. Despite a longer operation time, VATS could be considered an alternative to open thoracotomy sleeve lobectomy. VATS sleeve lobectomy is a safe and effective alternative to open thoracotomy in treating central-type NSCLC, as it results in less surgical trauma and quicker postoperative recovery without impacting tumor prognosis negatively. More well-designed randomized controlled trials are required to verify these findings.
