Selective Lymph Node Dissection for cT1N0M0 Invasive Non-small Cell Lung Cancer With CTR>0.5 Located in the Apical Segment: a Single-arm, Multi-center, Phase III Trial
This is a clinical trial from Eastern Cooperative Thoracic Oncology Project (ECTOP), numbered as ECTOP-1018. The goal of this clinical trial is to confirm the theraputic effect of selective lymph node dissection for cT1N0M0 invasive non-small cell lung cancer with CTR\>0.5 located in the apical segment. The main questions it aims to answer are: The 5-year overall survival of patients having cT1N0M0 invasive non-small cell lung cancer with CTR\>0.5 located in the apical segment; The post-operative lymph node metastasis and recurrence-free survival. Participants will receive selective lymph node dissection as the surgical procedure.
• Patients who sign the informed consent form and are willing to complete the study according to the plan;
• Aged from 18 to 80 years old;
• ECOG equals 0 or 1;
• Not receiving lung cancer surgery before;
• Resectable peripheral cT1N0M0 tumors with CTR\>0.5 located in the apical segment;
• Non-lepidic predominant invasive NSCLC dignosed by frozen section;
• Not receiving chemotherapy or radiotherapy before.
