Brief Summary:
This study is a prospective, multicenter randomized controlled trial (RCT) designed to compare the efficacy of segmentectomy and lobectomy for invasive lung adenocarcinoma with a diameter of 2-3 cm and intraoperative frozen section-confirmed IASLC pathological new grade 1-2. The non-inferiority of segmentectomy is primarily evaluated by 5-year relapse-free survival (RFS) and overall survival (OS) after surgery, while secondary endpoints include pulmonary function preservation, perioperative complications, etc. With a planned enrollment of 587 patients over a 3-year recruitment period and a 5-year follow-up, this study aims to identify an optimized surgical approach.
Detailed Description:
Lung cancer is the most prevalent and lethal malignant tumor worldwide. Surgical resection remains the most effective treatment for early-stage lung cancer, with lobectomy historically serving as the standard procedure. Recent studies have demonstrated that segmentectomy can achieve comparable outcomes to lobectomy for tumors ≤2 cm and those with ground-glass opacity dominance (CTR ≤0.5). However, for invasive lung adenocarcinomas measuring 2-3 cm with solid predominance (CTR \>0.5), high-level evidence supporting segmentectomy as an alternative to lobectomy is lacking. The 2020 International Association for the Study of Lung Cancer (IASLC) proposed a new grading system for invasive adenocarcinoma, which stratifies prognosis based on histologic subtypes. Tumors with IASLC Grade 1-2 (≤20% high-grade components) have better outcomes, but their optimal surgical approach (segmentectomy vs. lobectomy) in solid-predominant lesions (2-3 cm) remains unproven. Intraoperative frozen section has shown high accuracy in diagnosing IASLC grades, enabling real-time surgical decision-making. The primary objective of this study is to evaluate whether segmentectomy is non-inferior to lobectomy in terms of 5-year relapse-free survival (RFS) and overall survival (OS) for patients with 2-3 cm lung adenocarcinomas confirmed as IASLC Grade 1-2 by intraoperative frozen section.
