ABSTRACT
BACKGROUND:
Whether wedge resection is oncological suitable for ground glass opacity (GGO)-dominant non-small cell lung cancer (NSCLC) ≤2 cm is still debatable. The aim of this study is to investigate the short-term and long-term outcomes of intentional wedge resection and segmentectomy for those patients. MATERIALS ANDMETHODS:
This was a real-world study from one of the largest thoracic surgery centers in West China. Patients who underwent intentional wedge resection or segmentectomy for ≤2 cm CTR (consolidation-to-tumor) ≤0.5 NSCLC were consecutively included between December 2009 and December 2018. Data were prospectively collected and retrospectively reviewed. Inverse probability of treatment weighting (IPTW) was used to balance baseline characteristics. Long-term outcomes, including overall survival (OS), recurrence-free survival (RFS), and lung cancer-specific survival (LCSS), were analyzed using Cox proportional model.RESULTS:
A total of 1209 patients were included (497 in the wedge resection group, 712 in the segmentectomy group). Compared to segmentectomy, wedge resection had a significantly lower rate of complications (3.8 vs. 7.7%, P =0.008), a shorter operating time (65 min vs. 114 min, P <0.001), and a shorter postoperative stay (3 days vs. 4 days, P <0.001). The median follow-up was 70.1 months. The multivariate Cox model indicated that wedge resection had survival outcomes that were similar to segmentectomy in terms of 5-year OS (98.8 vs. 99.6%, HR=1.98, 95% CI 0.59-6.68, P =0.270), 5-year RFS (98.8 vs. 99.5%, HR=1.88, 95% CI 0.56-6.31, P =0.307) and 5-year LCSS (99.9 vs. 99.6%, HR=1.76, 95% CI 0.24-13.15, P =0.581).CONCLUSION:
Intentional wedge resection is an appropriate choice for ≤2 cm GGO-dominant NSCLC.
