BACKGROUND/AIM: The benefit of adjuvant chemotherapy for patients with pN1 non-small cell lung cancer (NSCLC) according to the location of lymph node (LN) metastases remains unclear. In this study, we examined the location of LN metastasis and prognosis to identify the significance of adjuvant chemotherapy. PATIENTS AND METHODS: Thirty-five patients with pathological T1a-2bN1M0 NSCLC who underwent curative resection between 2010 and 2016 were enrolled in the study. We defined patients with LN metastasis extending in stations 10-12 as the hilar group (n=22), and only in stations 13-14 as the intralobar group (n=13). RESULTS: There was a significant difference in the overall survival (OS) (p=0.042) and disease-free survival (DFS) rates (p=0.021) between the intralobar and hilar groups. In the intralobar group, there were no significant differences in the OS and DFS rates according to adjuvant chemotherapy. However, patients without adjuvant chemotherapy had a poorer OS (p<0.001) and DFS rates (p<0.001) in the hilar group. CONCLUSION: Prognosis significantly differed according to adjuvant chemotherapy in the hilar group.
