Patterns and risk factors of lymph node metastasis in non-small cell lung cancer 2 cm or less

Key Points

• Lymph node dissection can significantly impact treatment strategies for tumors ≤2 cm, especially regarding metastasis risk.
• For tumors in the upper lobe 1 cm or larger, the recommendation is to consider station 7 dissection for effective management.
• Assessment emphasizes the need for tailored approaches based on the tumor's appearance, particularly for GGO nodules.
• Findings highlight the importance of lobe-specific dissection techniques in managing lung cancer effectively.
