Evaluating lymph node dissection in early-stage lung adenocarcinoma

Systematically Mediastinal Lymph Node Dissection or Not in Stage T1 Ground-glass Dominated Invasive Lung Adenocarcinoma: a Multi-center, Prospective Clinical Trial

Not applicable Interventional Fudan University · NCT04527419

This study is testing whether skipping lymph node surgery can still help people with early-stage lung cancer live longer without their disease coming back.

What this trial studies

This clinical trial investigates the necessity of systematically mediastinal lymph node dissection (SLND) in patients with clinical stage T1 ground-glass dominated invasive lung adenocarcinoma. Participants will be randomly assigned to either receive SLND or not, with the primary endpoint being the 3-year disease-free survival (DFS). The study aims to determine if the non-SLND group can achieve a DFS rate comparable to the SLND group, based on previous data suggesting high survival rates. A total of 638 patients will be recruited across multiple centers to ensure a robust analysis.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 75 with a single ground-glass nodule diagnosed as clinical stage T1N0M0 and planned for curative surgery.

Not a fit: Patients with other types of lung cancer, prior thoracic surgeries, or those who have received previous treatments may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could help refine surgical approaches for early-stage lung adenocarcinoma, potentially reducing unnecessary procedures.

How similar studies have performed: Previous studies have indicated high disease-free survival rates in similar patient populations, suggesting potential success for this approach.
