The Clinical Outcomes of Thoracoscopic Versus Open Lobectomy for Non-Small-Cell Lung Cancer After Neoadjuvant Therapy: A Multi-Center Retrospective Cohort Study.
Clinical lung cancer(2023)
Abstract
BACKGROUND:The safety and efficacy of video-assisted thoracic surgical (VATS) versus open lobectomy for non-small-cell lung cancer (NSCLC) following neoadjuvant therapy remained controversial. The aim of this study was to compare the outcomes of VATS with those of open lobectomy for NSCLC after neoadjuvant therapy.
METHODS:Patients who had undergone VATS or open lobectomy for NSCLC following neoadjuvant therapy in nine hospitals in China from July 2014 to July 2020 were retrospectively reviewed. The clinical characteristics and overall survival (OS) of patients were analyzed using Cox regression models and propensity score matching.
RESULTS:We identified 685 patients, 436 (63.6%) who had undergone VATS lobectomy and 249 (36.4%) who had undergone open lobectomy. Patients who had undergone VATS lobectomy tended to have had fewer nodes removed than those who had undergone open lobectomy. However, compared with open group, the VATS group had a better perioperative outcome, such as smaller blood loss volumes and shorter postoperative stays. The groups had a similar operation durations and postoperative complications, and there was a nonsignificant difference between their 30-day mortality rates. After propensity score matching, there was no significant different between the OS of the groups, and only postoperative adjuvant therapy was associated with worse OS.
CONCLUSION:This multi-center analysis of patients with NSCLC who had undergone surgery subsequent to neoadjuvant therapy reveals that VATS lobectomy tended to have a better perioperative outcome, and have a similar OS compared to open lobectomy. These findings suggest that VATS lobectomy is appropriate for NSCLC following neoadjuvant therapy.
