European Multicentre Study Evaluating the Prognosis of Peripheral Early-Stage Lung Adenocarcinoma Patients Operated on by Segmentectomy or Lobectomy

This article assesses the outcomes of segmentectomy versus lobectomy in treating peripheral, early-stage lung adenocarcinoma. In a multicenter study involving 674 patients, the authors compared overall survival (OS), lung cancer-specific survival (LCSS), and disease-free survival (DFS) between the two groups. Five-year survival rates were comparable between patients undergoing segmentectomy and those receiving lobectomy, even for cases with aggressive adenocarcinoma patterns (e.g., solid or micropapillary). Segmentectomy did not emerge as an independent risk factor for worse outcomes, and no significant difference in locoregional recurrence was found.  This study is significant to the field of cardiothoracic surgery as it supports segmentectomy as a viable, less invasive alternative to lobectomy for specific patients, aligning with trends toward personalized surgical approaches.
