EP05.01. An Analysis of Lymph Node Metastasis Patterns in Surgical Cases of Non-small-Cell Lung Cancer - PDF(Abstract)

Pdf Summary

This study analyzed lymph node metastasis patterns in surgical cases of non-small-cell lung cancer (NSCLC) and examined the prognosis by primary site. The researchers included 441 NSCLC patients who underwent lobectomy and lymph node dissection between January 2013 and December 2020. They classified the patients based on the presence and number of metastatic lymph nodes. The results showed that the 3-year postoperative recurrence-free survival rate was highest in patients with N2a1 metastasis, followed by N2a2 and N2b. Most of the metastatic lymph nodes in N2a1 were included in the selective dissection area. However, skip metastasis to the N2b region was also observed, suggesting a need for further investigation of lymphatic flow pathways. <br /><br />The findings have implications for the TNM classification system and treatment strategies for NSCLC. Understanding the patterns of lymph node metastasis can help guide the selection of lymph node dissection areas during surgery. The study also highlights the importance of identifying skip metastasis, where lymph nodes in a certain region are skipped and metastasis occurs in a different region. This information may influence treatment decisions and improve patient outcomes. <br /><br />Overall, the study provides insights into lymph node metastasis patterns in NSCLC and their impact on prognosis. It emphasizes the need for further research to better understand the lymphatic flow pathways involved in metastasis. The findings contribute to the growing body of knowledge in pulmonology and staging, ultimately helping to improve the management and treatment of NSCLC patients.
