Molecular profiling of lung cancer and lymph nodes

Molecular Signature From Tumor to Lymph Nodes: How to Identify the Right Candidate for IIIA-N2 Lung Cancer Surgery?

Observational Assistance Publique - Hôpitaux de Paris · NCT04677205

This study is testing how the genetic makeup of lung tumors and lymph nodes in patients with early-stage lung cancer can help predict their recovery and guide better treatment options.

What this trial studies

This observational study aims to conduct a comprehensive molecular characterization of tumors and lymph nodes in patients with stage IIIA-cN2 non-small cell lung cancer (NSCLC) who have undergone surgery with curative intent. The study will analyze both primary tumor tissue and lymph node tissue to evaluate the impact of molecular signatures on disease-free survival. Additionally, circulating tumor DNA (ctDNA) will be assessed as a potential prognostic marker and surrogate for molecular heterogeneity, utilizing next-generation sequencing for accurate screening. The goal is to identify specific molecular profiles that may inform treatment strategies and improve patient outcomes.

Who should consider this trial

Good fit: Ideal candidates for this study are adults over 18 years old who have undergone surgery for stage IIIA-cN2 NSCLC with curative intent.

Not a fit: Patients with advanced disease stages or those who have not undergone radical lymphadenectomy may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more personalized treatment approaches for patients with stage IIIA-cN2 NSCLC, potentially improving their prognosis.

How similar studies have performed: Other studies have explored molecular profiling in lung cancer, but this specific approach focusing on N2 involvement and ctDNA analysis is relatively novel.
